I have a sigma dm2 serial "sk 230114" made in Korea. Headstock says sigma guitars est 1970. Paper label with pink rectangle. Adjustable truss rod at headstock and fixed bridge. I've read somewhere that this is possibly early 1970s. Any info would be appreciated.

I have seen a number of Sigma SDR-28H guitars with ebony bridges and rosewood fretboards. Normally the same wood is used.

Just to put a bit more information forward regarding the Sigma DM 4 model I'd flagged up a couple of months ago ...
The guitar had originally been purchased by the seller as a brand new instrument in 1983, from a shop in Liverpool.
The DM 4 model is based on the Martin D 18.
It was made in Korea for C.F. Martin & Co. - this is branded into an NFL football shape on the internal back bracing along with its serial number and model number.
There is no paper label inside the body.
The 'propeller' inlay at the 12th fret position is alternatively referred to as 'cats eyes' - we'd wondered whether this inlay design was significant to date of manufacture or materials of construction?
Any assistance would be greatly appreciated.

I purchased a sigma DR28 in the early 1980s from a guitar shop. It is in amazing condition still today and can see it definitely has a solid top. Sn 076081 made in Japan.
Does not have a paper label, oval stamped inside. The back looks to be two piece rosewood.

Can anyone tell be about this guitar? History. Is is laminate sides?
What would it be worth.
Only one owner. Loved and looked after by myself...

A pal has recently bought an old Sigma DM-4 acoustic guitar, s/no. 90090097.
There is an internal 'branding' - no paper label.
Significantly, it has what appears to be a propeller inlay marking at the 12th fret.
Allegedly, it is in excess of 20 years old?
I am trying to find out as much info about this particular guitar on his behalf - any info would be much appreciated.

Martin used to own them. When they sold them to a German outfit, they sold the rights to existing designs.

Sigma have improved the quality since moving production to the Chinese manufacturer the German owners use. Nowadays, all guitars from anywhere over £100 can be made to be ok. I've often considered adding a Sigma mahogany twelve fret parlour to the collection.

In terms of Martin copying, I have a Recording King, same solid woods and similar build quality (a bonus) to a D18. Stunningly good, embarrassingly outperforms some of my £2k+ guitars yet cost £390 new, and what's more, from Amazon.

The label appeal of large American outfits such as Martin and Gibson will always be there and smaller manufacturers here in The UK or increasingly Canada will always get the nod of approval when you take them out of the box.

But for concert bashing around, the likes of Sigma are becoming fairly widespread.

Add me to the list of Sigma owners who's not completely (or even close to completely!) sure what he has.

For starters, it's got the "Sigma Guitars, Est. 1970" headstock. What it DOESN'T have is Sigma label inside...though it DID have the "Picador" label that you hear about on guitars that weren't of first quality.

To that end, there's a lone number---2----on the inside where the Sigma label might have been; I had to peel off the "Picador" label to find that (was hoping for a little more than a single digit). The "2" almost looks hand-written, but I imagine it was done by stencil.

I've heard and read that "second quality" Martin-related guitars were often blemished or victimized by poor glue jobs. The latter is certainly true in my case; there's a nasty splash of glue below the sound hole which is not what you'd expect from any Martin product. It's led me to believe this was, indeed, a second-quality box.

Anyone got an intelligent guess on this? The previous owner thought it was a D-18 (based on shape and size) but I'm not quite convinced. If you know a Martin or Sigma expert with knowledge, I'm all ears.

Thanks!

I reckon they have come on well since Martin ditched them and the German company who know owns them have improved them.

I rather like their solid mahogany topped range, especially the 00 size. The 12 fret slot head is rather close to the Martin in sound when new, and set up correctly, is as rewarding to play.

I reckon it's headstock snobbery. If they had a unique headstock design to remove the poor man Martin image, I reckon they could stand on their own merit more. The £2-500 market is cramped and lot of good guitars in it, but when asked, I always advise people to give them a try. The more expensive end of the D28 copies, especially the D42 copies are too expensive for what they are and you can get a Recording King with similar spec and solid rosewood back and sides for around the same money and quality. The torch headstock being less of a "wannabe."

But I like them. I just see a difference between the newer ones and the ones Martin had made. The German owned ones are all made in China by the way.

I bought it used back in the mid 2005 to 2006. It is in almost mint condition but the tuning machines have been upgraded I believe. I bought it from and old man who owned a small music shop and at the time I was going to buy a blue ridge but he said this was a better guitar and I paid close to 200.00 for it used. Never seen or heard of another custom sigma. If anyone has info please share. It is a very good sounding guitar with great projection. Spruce top mahogany sides and back.

Date: 29 Jul 13 - 11:38 AM

I've been reading many of the previous comments, and wanted to see if I can find out more information about my Sigma CR-7. Sterling's comments (among others)have helped me, and are much appreciated.

Solid spruce, very even color and fine grain over the entire soundboard, along with great crossgrain. No logo on the headstock, but a paper label inside printed in gold, but has aged somewhat and look more like copper now. The label is stamped in ink CR-7 with a 4-digit serial number 6486 and Made in Japan. This seems to match with my research for made between 1970-1978, but I read that with that serial number it is likely it was one the earlier models, as the serial number eventually went to 5-digits for models manufactured during the early years. The rosewood is lighter in color than EIR, quite similar to my Renato Bellucci Concert classical, which is by far my best sounding nylon string guitar. But my Sigma runs a close 2nd.

My question has to do with the upper and lower bindings and backstrip purfling. It consists of light colored strips with a turquoise colored strip in between. I've never seen anything like it before, and it's never been identified by anyone who has described their Sigma classical guitar. It's difficult to see with the naked eye unless under bright light, then it really pops! Is my guitar different, or was the turquoise marquetry used throughout this early time period? Any help regarding the serial number or marquetry would be appreciated greatly.

Date: 10 Jul 13 - 07:38 PM

Hi all - since no-one else seems inclined to answer the spate of recent Guest postings about their Sigma finds, let me try...

1. Serial numbers of early Sigmas (70's to 80's) are of no help. It would appear that Martin didn't have any consistent system and their contracting guitar workshops, firstly in Japan, later in Korea (and there were quite a few over the years) probably used their own numbering systems, or just made them up. No-one to my knowledge has ever attempted to classify the serial numbers in a way which would identify the place or year of manufacture and I suspect that it isn't going to be possible now. Later models might, but I don't know of any sources for this. Serial numbers can sometimes confirm things: there are at least three Sigma 12-strings in New Zealand I know of with close serial numbers, which indicates that they may have been part of a batch imported here at the same time.

2. Model designations were sometimes stamped on the back brace and sometimes follow the Martin model designations. Mine is stamped "DR28-12", which means that it's a 12-string D28 body with rosewood sides and back. But sometimes they don't.

3. There is usually a "country of origin" brand on the back brace. This is oval, and is in three parts, the top lettering reading "Sigma Guitars", the middle the country (Japan on mine) and the bottom "C F Martin". Lacking this brand, the guitar probably isn't authentic (but who knows, really!).

And finally, Guests, do your homework! Read through all the posts on this thread. Yes, all 600-plus. You might learn something. The Sigma story is an interesting piece of history and learning about it will add to your experience when you pick up your guitar. Good luck - if you have found a nice old Sigma, look after it and it will repay you with many years of music.

Hi there

Great thread. About to take a look at the new Sigma range. I currently have two dreads a 70s Yamaha FG336 which sounds amazing and a Blueridge BR40 which is also a great sounding guitar once the poor intonation was sorted out.I like the idea of adding a rosewood backed guitar maybe in 000 shape. Certainly these Chinese clone guitars offer very good value for money but I begin to think they are pretty much the same guitars in different guise. Blueridge, Recording King, Eastman all look suspiciously similar in design and build. Still excellent guitars for the money but I wonder if Sigma are part of this club or offer something different.Thanks again for all the posts.

Awesome thread on Sigma Guitars...read as much as I could then skipped to page 15 14 & 13 to read the entries made by the illustrious Sterling Webb...this thread must be the authority on Sigma Guitars...Just purchased a Sigma DM 3 with 2nd Gen Logo and 800516 stamped inside...plenty of wear on the fret board which tells me someone loved playing this guitar...(well Shiela that is, since that's her name)...figure it was made in 1980 in Korea (also has the sticker inside saying made in Korea, and also a second set of numbers SK 107466 on the paper label, has an adjustable saddle, open backed tuners, oval thin tuning pegs)...perhaps not one of the coveted Japanese or "N" Sigmas but I love the clear crisp even tone...As someone who makes a living in bars and clubs in the Atlanta area playing some great Telecasters through old Fender amps mostly, this guitar has an even tone that is certainly more Martin like than my Takamine or Guild Acoustics...I appreciate all the info here...looks like a bone saddle and maybe a K&K Pure Pickup/Mic might be the way to get good tone amplified...I consider this a "Poor Man's Martin", which suits me just fine...I love it's tone...
Thanks, Tom Hill

Hi,
I have a rather unique Sigma, meaning that I didn't see any mention of it here after reading this whole thread (unless I missed it, lol). It is a DV-4M. A while back I did do some exhaustive research on it and found little info, but I did find some. At any rate, I acquired it a yr or so ago in pretty much "new" condition. It looked like it had never been played or even handled much. I fitted a bone nut, saddle and bridge pins from Bob Colosi on it and it really sounds good, exceptionally good! If any one can provide additional info about this model I would appreciate it,,,thanks.
PS - I tried a few different strings but this guitar really came alive with Dean Markley Alchemy goldphos CL 12-54s.

Great thread. I just picked up a a Sigma 12-string. Has a paper label that says "DM12-2" and it's made in korea and the "sigma 1970" in the martin script logo. Also has a sticker on the back of the headstock that says "made in Korea" so I guess it's definately not a Japan model.... I haven't been able to find much info about it though. One site says the model was only produced from '87-'93, but I've only found one source that says that, and I thought that the Korean models had Martin model numbers, and not the old japanese 2, 3, 5 etc. grading system. Sounds great though, and it's in fabulous condition. Even that sticker on the headstock isn't frayed or anything ;-) I'm happy with it, don't really care much about it's value or anything, it's a keeper, but a bit of history would be nice. Anyone have any info?

My dad passed away and left me several guitars. Anyways I need help identifying a Sigma guitar that I have. The hard part is the sticker is missing but I have looked and found a close match on ebay and I think it is a late 70s or early 80s one due to the style of tuners and logo.

Just wanted to add one more thought. I have seen in other threads where people were referring to the "side ways M" as the symbolic M for the Martin brand that was put sideways so that when the guitar was in the playing position the M would be right side up so people would recognize it as part of the Martin brand. Well, I am not about to claim that is not what the Japanese manufacturers had in mind when they produced the gen one headstocks, but the fact that the Greek symbol for the word "SIGMA" looks like a cap M laying on it's side is kinda ironic right!

I have a Sigma DR 45 with the Made in Japan stamp in back bracing that has the Sigma logo in MOP on the headstock. Interesting story about how I ended up with it. I bought an american strat from Guitar Center 4 months ago and about 2 weeks after I purchased the strat I was back in Guitar Center to buy some acoustic strings. Every time I am in the store I go to the acoustic room and play some of the guitars. I looked up on the wall that they use to hang their used guitars on and noticed at first what I thought was a Martin D45 from a distance with seeing the abalone inlay on the fingerboard. It also had abalone purfling on every edge of the body back and front. I saw the sigma logo and pulled it down to see what it sounded like. At the time I knew all about the sigma history with reading it on Wikipedia back when I bought a sigma dm4 from a pawn shop. The strange thing is the Guitar Center had the guitar labeled as the model being R200. Price was $499. The guitar sounded outstanding and very similar to my Gibson songwriter and sounded as good, IMO, as my Gibson J45. So, I handed the guitar to one of the guys in there that has sold me several in the past and asked him to hold on to it and I would be back in an hour. I went home and got the strat and traded it in on that sigma. They have a policy with new guitars that you have 60 days to return for a refund if you are not happy. Anyway, I really like the sound and seems well built. I can't tell if the back and sides are solid rosewood or not, but I know the top is solid spruce from the grain pattern in the soundhole. It only has a few light scratches and would be flawless except the white binding looks yellowed from the aging nitro finish. The Sigma logo is a MOP that looks golden when it reflects light. Gorgeous instrument that was obviously taken very good care of and prob lived in the case most all of it's life. I would imagine someone prob inherited the guitar and traded it in on a new whatever. The guy that sold it to me said they gave the guy $400 credit for the sigma and so only made $100 when they sold it to me. I still do not understand why they had it labeled as R200 and not a DR45. The stamp is not easy to see and when I was in the Guitar Center I had trouble seeing it and had to use my cell phone as a flash light to see the DR-45. I assume they couldn't really see it very well and didn't bother getting a light to look closer. Sorry for the long post.

Be wary of proclaimed experts describing Sigma models of solid tonewoods. Those who are active traders on Ebay may have a financial stake in proliferating misinformation. While Sigmas of the Japan build era are generally well crafted and they produce good sound, almost ALL of them are laminate sides and backs. Having owned several Sigmas, ALL with lam sides and back (DR-7, DM-5, DM-2 Korean, DM-1, and DM-1Korean and late DM-1ST), none can compare to my favorite git, a 1990's Korea built Alvarez 6010 model which has been confirmed by St. Louis Music--importer of the Alvarez brand-- as a handmade solid wood special. However, its price back in '96 was $675 with a hardshell case. Over 16 years, its playing action and neck have remained awesome, and the intonation at every string, every fret measures to virtual perfection. A special violin finish is a nice touch, too. It is more playable and has a more nuanced, balanced tone-- superior to the D10 Anniversary Sigma in my opinion. Written 9/27/2012

Well, thanks Olaf from Sweden, that was an interesting and useful comment about the New Sigmas and I agree with you that guitars tend to look better without a lot of bling. Glad to hear that the new owners seem to be keeping up the quality even if they are now made (as I understand) in China.

The rest of the new Guests, please don't ask for valuations on your Sigmas - it will depend on so many factors. Mudcat is an world forum and the value will depend on your local market, apart from anything else.

And if you read back the forum, you will come to learn that serial numbers on Sigmas tend to be decorative (internal bling, if you like) rather than informative. No-one, not even Stirling Webb himself, who hasn't been on the forum for years, could decipher the system Martin/Sigma used and they can't or won't say. It is probably correct to say that they didn't have a system as such, but each contracting guitar factory - and there were quite a few of them - used its own system, or just made the numbers up.

The only things that mean anything at all are i) the country of origin stamp - usually branded onto the internal brace along with the model designation and ii) the shape of the headstock "Sigma" . Internal labels are also quite useful if they are there, but they aren't always...

If you really need a valuation, take it to a guitar professional.

Great Forum and THANK YOU hugely to all who have contributed.

I found in a Maryland junk pile my Sigma SDM-18...wooden burn stamp inside Saying Korean.

I rebuilt the headstock..reattaching it to the neck with some walnut (I am restoration specialist and this bit of luthiership appealed to me)

I loved it!! deep abiding love. I play for myself.

Now...from one of the inspired messages I just found here, I machined a perfect replica of the Saddle from 1/8"Brass..old soft brass..
I lifted the action a scant hair in the process.

And it sounds like a clarion to all other dreadnoughts!

Great advice!

Great informational post. Thank you mr. Webb for sharing your passion.

I have a DR12?. The label was missing when I got it a few years back. It clearly is from the 70's as it has the first generation headstock logo and adjustable bridge. I am pretty confident it has a solid spruce to and solid rosewood back and sides. The guitar is probably 8.5/10 for overal condition. I would say it is at least a grade 4 instrument in Sigma's scale, could perhaps be as good as a 7.

I am considering selling it so that I can find a same period DR7. If anyone is interested please contact me at [e-mail].

i have a sigma DR7 with serial # 3151 that i bought and haven't played a whole bunch. i recently got it down and played it some and found the action was way too high for me. a pro-setup finds the neck is somewhat warped and it has been heated/clamped and straightened twice, but it keeps going back.

question, is it worth putting more $ into it? the tech says he thinks the best thing is to take the fingerboard off, reface and reinstall the fingerboard, or something like that. i'm not sure i understand what he's saying. i hear the words, but the meaning is foreign.

i have abt $350 plus setup in it right now... but it isn't worth a dime to me this way. if all i played were cowboy strums in first position, it'd be fine, but up the neck the intonation and touch go crazy.

sooo, what's your opinion?

Hi there all Sigma fans/owners !
Just found this VERY informative discussion about Sigma Guitars, thank you all!
There's a comment from "Fossil" (16 may 2012) about if anyone have a new Sigma.....well, I have recently bought a new DRC-28E, this one:

http://www.sigma-guitars.com/index.php?id=257

I paid 440 euros from a Ebay dealer (about 550 USD).
New, only unpacked and used for his photos - and it was "as new" when I got it!
Sigma Guitars hompage says "listprice" 670USD.

I was searching for a good "mid-price" acoustic, and ended up choosing between the DRC-28E, a Takamine EG340SC and a Tanglewood TW115-ST-CE, but finally decided for the Sigma, mostly because it looked best, in my opinion. Classic without a lot of sparkling inlays and bindings.

I must say that it's great value for the money (without beeing an acoustic expert). Sounds great, specially after changing the original Martin 0.10-strings to Elixir 0.11's. Think that 0.12's will improve the sound even more (but beeing a mostly electric guitar player using 0.09's, my fingertips have to take it "step-by-step")
The changing of strings was something someone at harmony-central recommended:

http://acapella.harmony-central.com/showthread.php?2884779-Sigma-DRC-28E

Haven't been able to compare to a real Martin, but played it A/B with my friends Gibson (don't remember which model, but it's quite similar, a dreadnought cutaway) and actually he was a bit...hmmm...."confused" that my Sigma sounded so good compared to his Gibson which he bought for about 3-4 times as much. Of course there was a difference in sound but no one of us could say which one sounded "better".
Also did some A/B-ing with my other acoustics a DEAN "exotic zebrawood" and a LAG T200D, both dreadnoughts, no cutaway, no electronics. Selling my DEAN now.....no place for more guitars !!!

So - my "5 cents" must be "great value for the money".
Looking for and older/used/vintage SIGMA now.........to eventually replace the LAG T200D

Best regards

Olof from Sweden

One thing we can certainly be assured of with Sigma guitars: We are not likely to ever unravel all the mysteries about them and their origins.

Even though this discussion centers around a finite space of time, I believe that it will never be truly over. There are simply too many inconsistencies surrounding their make-up and manufacturer(s.)

With regards to Sterling Webb, and I do thank him profusely for the information he has provided, I must say that from my own personal experience I can not agree with all he has said. He should not take my comment as an insult because I too am aware how difficult it is to consolidate and verify information about these wonderful instruments. As stated, even Martin seems confused and will only offer "stock" answers these days. In fact I got a rather rude reply to a query I made about my guitar a few years ago.

I have often wondered if Sigmas were made by more than one Japanese company in those days which might explain the model and serial differences as well as other physical inconsistencies/ discrepancies?

Some personal history: From the time I was about 6 yrs old, I wanted to be a drummer and became one. However, while in college in Bethlehem, Pa. during the mid-'70's about 10 miles from Nazareth I began to realize that not everyone appreciated the drums, especially the girls, and that drums were much, MUCH harder to carry around than a guitar. So in short and having a few guitar playing friend's, I too took up the guitar.

My best friend had purchased a brand new D-18 around 1974, so he & I went to a local music store on September 23rd, 1977 to check out what was there and in my price range. In short, and knowing I wanted a 12-string, we decided a new Sigma DM12-5 was the guitar for me. $199.50 retail plus another $35.50 for a good hard shell case... which I still have BTW.

I'm sure the guitar had been there for at least 6 months before I bought it so it must have been a '76 or '77 model. The serial number was 017482. It had open-back tuners which have held up better than the frets over the years. It also had the Martin style headstock decal (Sigma Guitars/Est. 1970,) which Mr. Webb calls the second gen instruments beginning around 1980. Obviously this can't be completely correct.

And up till now, I always assumed it was a plywood guitar but it sounded so sweet and had decent volume too. I had removed the rear strap pin on many occasions and was never able to truly tell.

So about ten months went by and this instrument began to belly, badly! Being so close, I took it to the Old Martin factory (c1835) on North St in Nazareth (June 27th, 1978 to be exact) which was then being used as the "Import House."

One of their luthier's looked it over very well and even though I begged him, he said it simply was not worth fixing. He went to another room and brought out 3 brand new DM12-5's, fresh from their boxes and asked me if I liked any of them? If not he would get three more. I chose one and handed it to me and said, "How do you like that?"

I told him I was new to guitar but really liked the way the other was set up. So for the next 2- 2-1/2 hrs he tediously went over it and adjusted everything, occasionally handing it back to me for my approval. When I was satisfied, he installed a new set of Marquis strings for me (my chosen strings) and carefully put it in my case for me. "Here ya' go!" was all he said. I wish I knew who he was and where he is today. I would love to be able to thank him much better than I was able then. Nice guy, and very patient with someone who wasn't quite sure what he wanted at the time. I played that (2nd) guitar for over 30 yrs.

Fast forward to Sept 2009, the Friday before Labor Day. While at work, our home was broken into and three of my guitars were stolen... the three I played regularly (naturally,) among them the 12-string. I was heart-broken. 31 yrs of friends, parties, playing with friends and Gigs, all gone.

So I went in search of another 12-string and purchased what I think is a '79-'80 DR12-7. Pretty std stuff, except the "economy" tuners were bad so I replaced them. Also the bridge pins, saddle and nut were replaced w/bone.
A few weeks later I also purchased a 52SDR-9 which by and in all views seems to be made of solid woods!!

I've had it all apart, looked inside with an inspection mirror, etc and am still looking for further clues, but it has the 1st Gen Sigma headstock logo, beautiful rosewood 3-pc back and sides, non-adjustable bridge, no zero fret, interesting fret board inlays (not quite like snow flakes. More like a maple leaf in mirror image of itself.) single bound headstock and fretboard. Currently I am having a few frets professionally replaced and a bone nut/saddle installed on it too. When it comes home, I have new tuners (Grover 18:1 ratio) to install as well, and the case it came with to do some repair work to.

As a Sigma owner (Japanese DR28-12, 1982) who has been watching this thread forever, it's a bit sad to see that this whole page is Guests, who obviously haven't bothered to read back to the informational stuff.

Believe me, it's worth doing.

So, Guests, whoever you may be. Your Sigma is worth whatever you can persuade the market to pay for it. No-one here is qualified or can can be arsed to give you a valuation. If you read back the thread, you should be able to get a county of origin and might, just might, be able to get a date for it. Japanese-made ones are the cream, really early Japanese ones are the creme de la creme. Otherwise it's up to you to spin the story in your sales pitch.

Stories of interesting or rare variations (viz, the MoP headstocks) are that; interesting. We'd all love to know the full story, but it doesn't look like we ever will.

Anyone yet bought/tried/played a New Sigma? That would be a really interesting contribution...

Thanks in large part to the information in this venerable thread (and a special hat tip to Mr. Webb, wherever he may be), I just bought a DR12-7 for a bit under $300, and I almost feel guilty of theft. Great tone, great volume & projection, no bridge lift or belly buckle. Stout as can be, and cosmetically 9/10+. I don't pose as an expert, but the back & sides are either (a) solid rosewood, or (b) a laminate with the external and visible internal grain perfectly matched; and I'm certain the top is solid sitka, judging from the visible soundhole grain. I've not removed the endpin for a closer check on the side wood, simply because I don't want to risk it. Personally I don't greatly care, but my tentative conclusion is that it's solid wood all around, & that jibes with what Mr. Webb and others have stated. There is some Sigma inconsistency, however: it has the original headstock logo, a zero fret, and an adjustable saddle, all (especially the zero fret) supposedly indicating a '70 - but the paper label seems to be the 2nd type and has a long serial number beginning with "74", indicating (again according to a Webb post) perhaps a '74. In any case, she's a hell of a 12-string in my book, and way ahead of the beater I was expecting to get for what I could spend.

Officially Sigma are no more, but Thomann - a german mail order company - seems to have them for sale.

Go to www.thomann.de and search for sigma guitars - they have more than 10, all strikingly similar to Martin models, in naming and spec, many in stock, the others available in 2 to 5 days.

Has production restarted?

I sent an email to Martin to ask but they didn't answer (yet)

I have a Sigma OMC Sunburst finish acoustic electric Model OMC-3OS, volume and tone on the upper body near the neck, made in Japan with an OVAL sound hole - similar to the Keith Whitley guitar shown on the site
http://www.facebook.com/note.php?note_id=10150361283484477
This is the only location I have seen showing anything even resembling this guitar. It has a sharp edge cutaway while mine is rounded, and the cable jack is out the bottom, while mine is integrated into the strap peg at the end of the guitar. Any ideas on the origins and value of this guitar would be appreciated.

Amazing to see that this thread is still running, some six years since the Sigma brand ended! What is it about this mysterious brand? My experience is limited to just one, a Taiwanese made DR-28 from c1995. It's still just about my favourite all-rounder guitar.

I bought my DR-28 new from Hanks in Denmark Street W1 in '96 or '97. It was my first "half-decent" guitar so I didn't know anything about the make or the woods etc. The sales guy asked me what I wanted and I said that I want a Martin dreadnought but couldn't afford one. He immediately pointed me towards the Sigmas (as well as a few other similar priced guitars), and this DR-28 just rang out louder and clearer than any of the others (including a Sigma DR-28H) so I bought it for the asking price (which was <£300). They also threw in a hard case.

This guitar has been a mix of good news and bad news:

The good news is that, 15 years on, this guitar sounds bigger and better than ever. I know I've upset a few Martin players (particularly those with new Martins) because it sounds better than the DR28s Martin are currently selling (I appreciate that this could be an "age" thing). Strange thing is that I still envy them their Martin logos (silly old superficial me!). I recently replaced the plastic saddle with bone and the pins with ebony, and it now sounds even better. I've also fitted a K&K pure western mini pickup which replicates the acoustic tone faithfully.

Now for the bad news: how do I upgrade from here? could I be happier with anything else?

Since my playing has improved over the years (and my bank balance) I felt it was time to get a "really decent" guitar. I spent many hours playing new Martins and Taylors up to the £1500 range, but none of them came close to the sound of my Sigma. Again, perhaps this is because they were all brand new, or maybe down to the horrible habit that guitar makers/shops have of putting coated strings on their stock guitars. Either way, it was terribly disappointing (I still really wanted CFMartin on my headstock, even if it cost me more, but not at the sacrifice of tone and sustain).

In the end I bought another far-east made guitar (a Freshman FA500 GACED) which is a very lightly braced, highly resonant, Cedar/Rosewood tone machine that is great for fingerpicking Celtic style music and is a great addition. It will not, however, replace the Sigma.

My most recent acquisition is a beautiful, hand-made, custom Brook Tamar. For about the same price as a new (production line) Martin D28. This has at last satisfied the itch for a high-quality, well made, guitar that represents the best of the Luthier art/craft. It has a wonderful tone that sings out even though it's still less than a year old. It even gives the Sigma a run for its money, although the Euro-spruce, claro walnut combination of the Brook provides a very different tonal palette.

Anyway, my points are: you don't have to spend a lot of money to buy a great sounding guitar; spending a lot of money does not guarantee a great sounding guitar; buying an iconic "name" does not guarantee even a "half-decent" sound.

I still regularly gig with my Sigma, it's perfect for that Neil Young sound, and I'll never part with it (except to hand it on to my daughter when the time comes). I've dropped it several times, and it bears the scars of battle with pride.

If I sold it now I would never get its true value. If you can find a decent one (of any period) grab it, it will be a bargain you will never regret.

I need the money to deposit towards a classical guitar that Iʻm having built.

The wood is part of the problem - it's not as dark as the rosewood sigmas I've seen - is is a lighter almost caramel color with a slightly wider grain... Don't suppose this is a DJ-7? The guitar has the white binding on the headstock and body, rosewood bridge and fretboard - very odd

Subject: RE: sigma guitars

Date: 08 Sep 11 - 02:01 PM

Well, Oddball, you should be able to tell right away whether or not it is a DR or a DM. The difference is pretty big. Rosewood has a lot of wood grain throughout and Mahogany has smaller grain lines and is lighter. If it has the greek letter headstock, then it was made prior to 1978 and in Japan. There were no DM-7's as far as I know. DM-5 is highest, unless you talk about newer models like the D10 and others. Could be a DR-7 though. There is no real way to tell the number 1-7 though. You can only guess if the label is missing I think.

So, I recently found an oddball sigma that I had to pick up - it's clearly a 70s model; greek letter above the sigma logo. The guitar is, unfortunately, missing the label from the inside, so I have no serial or model number. The guitar seems to be a DR or DM 7, judging by the body and headstock binding. However, the bridge is not adjustable. It's either a replacement bridge, or, like I said, an oddball model. Any ideas?

I recently found a 1979 (Ithink) Sigma DR-7 that had been hanging in a music store for about six months. After learning the Sigma story, I bought it. There was a wall full of pretty nice acoustics in the store, and with the dead strings and no setup, this guitar sounded as nice as they did, minus the dampning effect of the strings. I took it to a high quality luthier and told him to make it a "player". The nut and saddle had already been replaced with some very inexpensive plastic ones, so he made new ones out of bone, set the truss and string height, and did a nice intonation setup. I thought it was good when I bought it, now it rings like a bell! The increase in bass is incredible, and I now have a very nice guitar that sounds really nice, is very playable, looks great (not a scratch on it), stays in tune, and didn't break the bank. I'd put it up against alot of much more expensive models I have played and heard. If you can find one in good shape, and it has the solid spruce top and is made in Japan, buy it and get it professionally set up. You will not be disappointed.

Subject: RE: sigma guitars
From: GUEST,B-Rad
Date: 06 May 11 - 04:54 PM

Didnt have time to read through every post, but here is what I (think) know about sigmas.

-DM or DR 1-7's ....1 being lowest grade woods, 7 being best. early 70's models have sideways M, some later 70's models have sigma guitars EST 1970.

- 1983 moved manufacturing to Korea. Then late 80's moved to Taiwan. Taiwan models are the worst of the bunch, Jap models are best, but some Korean models can still be quite nice in sound.

If there is an S in the Model number, most likely a solid top. The laminated backs or sides are all over the place, you have to look to see if the wood grain in the sound hole is there for solid backs and sides.

- DM1st models are solid tops,the ST stands for it. some have laminated sides and backs, some have solid sides and backs.

- The DR 28, DR 18, DR 15, DR 11 and some others are all over the place. Some are really nice, some are not. DR 41's are really nice if you find an early model I think.

Look up Sigma on Wikipedia for some other good info.
Everyone asking what their Sigma's are worth are not really going to get an accurate answer. The market can only really decide this. Whatever someone will pay for it I guess. The problem is, you need to hear them to know if it's a lemon or a good one. I've heard of early DR1st models sounding way better than DR -7's and I've heard that some Sigmas sound better than some Martins. Me personally, I would take an old Sigma over a new Martin. You can't get that aged wood tone on a modern built guitar. AND there alot cheaper.

I have a 1970 DR-7 that I am needing to sell. The paper label has come out, but I discovered an interesting marking where the label should have been and where they later burned in the "Made in ...." It reads 47.6.21
My guess (and that's all it is) is that, perhaps before putting on the label with a serial number(which is useless for dating Sigmas)they did put on a production mark, in this case 6/21 #47. If that were the case, this would be a fairly early guitar since they began introducing them in Spring 1970. It has the zeroth fret and the original adjustable bridge. I would rate this in very good condition (9/10) with no repairs or damage. E-mail me for pics or with an offer @ [e-mail]. Thanks. I may put this up on EBay if I don't get any response this week.

Greetings! I've a Sigma GCS-6 that I purchased new in 1974 after sampling similarly priced Yamahas, etc., and the Sigma outshone them all. This info should be pretty accurate for dating GCS-6 Sigmas made from '70-78. The early models were solid wood, in this case a spruce top, mahogany sides and back, rosewood bridge. The original peghead logo for Sigma is in gold with Greek symbol Σ above in mother-of-pearl. There is a paper label with a silver gray border which has SIGMA with CF Martin & Company underneath. Then there's the model, serial number and "Manufactured in Japan". On the back of the peghead there's a label that reads "Made in Japan." I never learned to play her but now I think I will.

I know it says here if they do not have the M on headstock they cannot be a 70's, well, I SWEAR I bought mine new in 79, has the Sigma guitars est 1980 emblem. serial #020909, no adjustable bridge. I graduated High School in 1980, I KNOW I bought it while still in school. I remember playing it with my first band at an outdoor party, so it would have had to be summer of 79 as I graduated in May 1980. Let me know if you think this is possible.

Haven't been here in a long time. Took my DR-28C to a pro last June. Got the frets dressed and brought the action down as far as practical. I paid $350 or $375 for this guitar and a nice, hard case when I bought it from a coworker, a few years ago. I've been trying to get the action down myself. Every string change, I would sand a wee bit off the saddle. Eventually figured out that my favorite strings for this guitar and my clumsy fingers are D'Addario Custom Lights. Also figured out that it would be good to let a pro set it up. I spent $93 on the set-up. It was worth it, to me. The guitar still sounds great (some buzz can be induced if frammed on really hard), and it's easier to play. Other than strings, I've got less than $500 invested. Me happy.

Just picked up a dr 28, which looks nearly new except for the nice colour and patina. Put new strings on it and wow, I'm amazed at the sound. Now I always thought that all Sigma's were laminate back and sides, but if I look very carefully and follow the grain pattern inside to out all around the sides and back, it matches the outside. This would make me think solid, but I was under the understanding they were laminate. Does anyone know if they grain matched the inside and outside of their laminates?

I guess in 1980 I got tired of my '59? Les Paul Jr 3/4 (wish I still had it tho) and Ray traded me straight up for a Sigma which was my acoustic ever since. Recently it started buzzing from too many hard knocks, needed frets, had deep gouges in the fret board, etc so I started considering purchasing a new guitar, but I couldn't justify sending over $1000. Thing is, even though I knew Sigmas don't necessarily rate high, I always liked the tone, the neck, and overall playability. So when I started trying to figure out what I had, it turned out to be the D10 Anniversary, and only ONE OUT OF 100! Long story shorter, I just spent $500 having it refretted, the end block refastened, and some amazing refill on the fretboard. I couldn't be happier. Cosmetically, it may never be worth what I put into it, but that's not the point. So thanks to this and other forums for validating what I always suspected - I have a really nice instrument.

Here in the US, Sigmas are pretty available used. I got my first and current 52SDR-7 rosewood git new in the latter 70's, and it has aged beautifully. Its action and neck yield no ground to any Martin I have plunked on (not to say I wouldn't want one), and after setting it up with Grover tuners and bone nut and saddle, I'm set to keep it as my go-to guitar. I've recently acquired a Sigma DM-2 in mahogany (build nation not stated on soundhole label or otherwise marked), which needed truss-rod adjustment, re-hydration, a bit of fret tweaking, and nut replacement, and it now has great attributes, though mid and upper fret action a bit higher than on the DR-7. I got crazed and worked the soundhole to Martin's D-28 Clarence White edition specs (plus pickguard mod) and it really cranks out volume! Next guitar? Don't know, but I am mighty impressed with the 1970's vintage K. Suzuki guitars out of Nagoya, Japan.

i did a bone saddle only. that really opened up the sound. went from being tinny to nice full lows and highs. this is my travel guitar so its been exposed to the elements many times and always took it well.
don't think the hd-28 could take the same abuse. we'll see after a few years of ageing.

i wanted to reply to this particular post so i reprinted it. the 4 digit # 3993 is shown on the paper label as the serial #. the 227 is stamped on a brace near and under the sound hole.

i took it to a technician friday morning and he thinks its a solid wood. regardless, he says, i got a bargain! so i'm tickled. we're "boning" up the saddle and nut. i have a set of tusque pins and bone pins, i'll see which sounds best.   i've been told the tusque provide a bit more sustain than bone.

Pardon me again, everyone---I think I might have answered my own question as to the SE-19's vs. the SEMC-28's.
Found this on ebay (the auction has ended, so you'll have to scroll down to view the pic of this guitar): http://cgi.ebay.com/Sigma-SE-19-Acoustic-Electric-Made-JAPAN-w-extras-/220644619262?cmd=ViewItem&pt=Guitar

This guitar is identical to my SE-19---the inside is also stamped with "SE-19". I personally feel the guy sold it for waaaaay too low (perhaps his frustration with the pick-up had something to do with it---I had the Martin factory in PA replace mine in 1992, and I've never had a problem with it since). Also, the inside of the guitar looks pretty dirty, so I'm guessing it either had no case or a cheap gig bag (he states he bought it originally off eBay also, so who knows where all this guitar's been).

Thanks everyone for your indulgence---didn't mean to leave so many posts, but I kept being riveted to more and more searches on Sigmas and finding more info.

One additional note to add to my previous post:

I read on some other "Sigma info sites" that "S" sometimes can mean "spruce" or "solid". Apparently it can depend on the guitar's appearance itself (when you get down to it), as some variances in the "letter model's meanings" I have read could fluctuate as a result of different countries of manufacture over various years.

I am convinced that the SE-19 that I have is sapele wood (as I mentioned in the previous post), and here's why: I've seen guitars with "spruce" wood---my SE-19 looks nothing at all like spruce. The wood of my SE-19 is very characteristic of sapele---it is a reddish-brown wood, with the grain having the characteristic "interlocking and changes in direction in frequent, irregular intervals" (http://www.eastteak.com/products/finehardwoods/sapele_data.html ). This would explain why the guitar appears to what I call "shimmer" and change wood tone color depths, depending on how the light hits this unique grain at various points. All 4 sides of this SE-19 are the same exact wood: sapele. The only contrasting wood is on the bridge support and in the decorative "Native American-looking" stripe I had mentioned that goes down the back (as well as of course the fret board and front of the headstock). Everywhere else, it's the same reddish-brown, intriguing grained wood.

My only confusions are these: a Wikipedia article on Sigmas stated that the SEMC-28 had the "arched back" (I realize that Wikipedia can be wrong on many things, however). My SE-19 is stamped (as I stated above) on the inside bracing as an "SE-19"---yet, the back of it is slightly rounded (not sure if this would qualify as an "arched back", as it certainly visually appears to qualify for such)---is it possible my SE-19 is actually an SEMC-28 and was stamped wrong? Or is Wikipedia wrong? Is the SE-19 also an arched back and Wikipedia just failed to mention that feature for the SE-19 as well? These are just a few of my questions.

Furthermore, my SE-19 is a cutaway (a thin-bodied acoustic electric with the cutaway as described in my previous post). The SEMC-28 (from what I understand about these letter codes) is also a cutaway, as the "C" apparently stands for "cutaway"? This further makes me wonder if someone stamped my guitar incorrectly as an SE-19 rather than an SEMC-28. I would certainly think, however, that since Martin inspected these guitars before sending them out to the dealers, they would have caught any possible "mis-stamped" guitar in their inspections, if a "mis-stamp" were the case. I don't know.

The only way I would know the differences in these guitars is if someone knows a lot about these 2 specific models, or I had a picture/specs of the SEMC-28 to compare my SE-19 with. Anyone that has any comments or solutions for my questions, I greatly appreciate your help;)   I don't think I can email Martin, as they state on their site that they don't keep serial number records for Sigmas--so I highly doubt they would have kept specifics such as these on record, or the number of how many SE-19's or SEMC-28's were actually made.

Many thanks to all who have contributed history and information here--I've found it all extremely helpful;)

I've got an SE-19 I received as a gift from my father in January of 1985--I was 15 years old when I first received this guitar, having only been playing guitar for 2 years at that point. Thanks to this forum, I now finally (after all these years) know that the "S" stands for "sapele"--I never knew the wood this guitar was made out of; but after reading about sapele wood and it's characteristics, it certainly explains why this guitar appears to "shimmer" when light hits it various ways!

My SE-19 has an oval sound hole, with alternating black and creme stripes going around it. The back of this guitar is somewhat rounded, but only very slightly, and with a "Native American-looking" type of designed stripe going down the back, the stripe itself being made up of inlaid wood, of a darker brown color and creme color. The cutaway ends in a sharp point, not the rounded curve you saw in later Sigma models. The logo on the head stock says "Sigma Guitars, Est. 1970", and has a "gold-look" to the lettering. Looking through the sound hole to the inside, you see burned into the center bracing the words "Sigma Guitars Made in Japan for C.F.Martin & Co.", as well as the "SE-19" to the right of that. Further up (on the same brace) near the neck joint, there is a 7 digit number burned in, but the first 2 are burned in very darkly, as though on purpose--I can't make them out, and one might even be a letter (it looks like "S") as opposed to a number; but the last five numbers are "11968".

The thin binding around the front edges of the guitar body matches the brown and creme stripes that surround the sound hole; the binding on the back of the body looks like those mottled guitar pics, the dark reddish tones with splashes of lighter rust color---like those reddish brown Fender Tortoiseshell guitar picks.

After more research tonight, I discovered that the SE-19 was one of only 4 Sigma models (along with it, the SE-28, SEMC-28, and SE-36) that were manufactured for no more than 4 years, and the quantities of each were extremely limited (much more so than I had thought before). I'm trying to find the exact number of SE-19's made, but still haven't come up with that yet. Does anyone happen to know?

My father purchased my SE-19 brand-new in a Martin dealership store in Newark, OH--he got it on sale, the half off price bringing his purchase to only $300 or a bit over. He was so excited to bring this guitar home to me. He chose it because, as he proudly stated, "it was the only one like it---the purtiest one in the store!!"

A few years later (1989), I took my SE-19 to the Martin store where dad had purchased it--they were having a free "String Day", where they'd put the strings on for you as well. I thought, "Why not? It'll save me for once the job of putting on new strings--be nice to have someone else do it for a change." While the strings were being changed, a crowd of guys gathered around my guitar---and within minutes of finding out it belonged to me, 3 of the guys were bidding for it, each offering to write me out a check. The highest bid was $3,000. I told them that the memories attached to this guitar were too great and beyond what any of them could pay. I knew the guitar was also quite unique, and no way was I going to get rid of it for anything in the world. (Some guys thought that because I was "a girl", then they would somehow be able to persuade me to give up the guitar. I let them know that this Sigma was NOT for sale, nor would it ever be.)

I don't know what this guitar would be worth today. It does have some wear around the first 3 frets (from the old "capo use" days, before I had discovered bar chords--lol), as well as some scratches/finish cracking around the plug in jack; I had the pick-up system replaced (it was faulty) by the Martin factory in 1992, and they fixed the finish around the plug in jack. Aside from those cosmetic flaws (which are only noticeable to the player or someone really looking closely at the guitar), this SE-19 is in extremely good shape. It's only had one owner (myself), and I've had it for 25 years. I'll never give it up.

Thanks for all the Sigma info here---very difficult to find info on these older guitars;)

i received mine this morning and i'm amazed by the sound. it appears to be about a 75 model from the information earlier in the thread.

the serial # is 3933, it has the paper label, the bridge is NOT adjustable... the M is pearl and the Sigma is gold.

i can't tell if its lam or solid. i pulled the end pin, and its really a pin, not a screw in, but a push in, but i still couldn't really tell.

doesn't matter though, other than for a bit of ego. i have another acoustic that cost 3 to 4 times what i paid for the sigma, and the old sigma puts it down...

does this serial # tell anything? there is another number burnt into a brace near the sound hole, 227. any idea?

however, i just got a brand new hd-28 martin for a great price.when i got home, of course i had to compare the sounds between them. when played side by side, the martin has better sound,at least i think so. but for value, you can't beat the sigma.

I have 2 Sigma's. A DR 28H ser. 96531 purchased in 1980 as a campfire guitar, and a DM 12-5 ser:23257 which I traded for a fiddle in 1981. They both have exceptional tone but the DM12-5, which I play as a 6 string rather than 12 has the sweetest, richest, softest tone that brings goosebumps when you listen to it. These guitars have a beautiful vibrating sound unique only to themselves. I am also familiar with old Gibson (sort of like myself), Fender, and Martin, and although these old classics are great sounding and smooth to the feel and aged with time, sweat and possibly spilled beer, these two Sigma's aren't far behind.

If you come across a Sigma missing it's logo and has the label removed or inside marking removed it's because it is a Sigma factory second. I recently purchased a Picador 12 string guitar for $100. After peeling the Picador metal label from the headstock I found the Sigma E and the faint outline of 'Sigma' still in the finish. The outline of the removed label is still visible thru the soundhole.
I am still trying to figure out the model number but it is a very early 70's model with an 0 fret, adjustable bridge and open tuners. I'll soon be turning it over to Roy Toepper at rtcusomguitars.com for upgrades and to clear up a bit of a clouded finish.
I also own a 52 SDR-7 that I just love. I still wonder though about the exact age of this guitar because this model was supposedly produced from 1979-81 yet the Head has the Sigma E and a paper label which supposedly ended in 77.

I have acquired what appears to be a 1970 GCS-7. The paper label is all but removed, however, it has an adjustable bridge and the "zeroth" fret which narrows down the production year (according to Sterling Webb's descriptions). It looks just like the Martin 000-21 with rosewood back and sides. I've never seen one of these before, so I have no idea of it's value (compared to the DR-7 which are always coming up on EBay these days it seems) since there is little to compare it to. I am also the proud owner of 2 Japanese made DR-28's as well as a D-10 Anniversary model, all in great condition. I am looking to sell the GCS-7 as well as possibly one of the DR-28's.

After many many years of not playing anything, I dug my Sigma SDM-18 out of storage and brought it to my local guitar shop (shout out to Noll Guitars in RI). After a fresh set-up, strings, etc, she sounds gorgeous.
Here's what I know about this guitar:

-I bought it new somwhere in the mid 80's, certainly no later than '88.
-It has "Sigma Guitars est. 1970" inlayed on the headstock.
-Stamped inside on the back brace is: 286982, this is followed by an oval shaped stamp which reads "Sigma Guitars made in (?unreadable)for CF. Martin & Co", followed by "SDM-18". Also inside the guitar on the base of the neck is another number which reads: 804158.
-By looking at the edge of the soundhole, I can see the woodgrain countinuing through leading me to believe that it is a solid top.

From what I've picked up in this most excellent forum is that:
A. The "S" in SDM-18 may stand for "solid", "D" means "Dreadnought" and "M" means "Mohagony"
B. The stamping on the back brace, as opposed to a paper sticker, gives it a build date in the 1980 - 1984 range.

Anyhow, I love the sound and playability of this guitar. It has inspired me at 46 years old to take some formal lessons and learn to play her for real.

Gidday to anyone thats interested by the same facination with sigma guitars that i have been afflicted by since first strumming an old ex buskers DR28 for sale on behalf in a guitar shop many moons ago.
I have played gibsons,martins,takamine,larrivee and guild among others of similar stature but consider the tone produced by the japanese made guitar from this era as superior.
On close examination of the construction it appears to have laminate back and sides,solid,fine grained spruce top,20 fret neck,serial no.847721 made in japan stamped on the back brace(which would place the date of construction between 1979-1983)from 1984 on they were built in korea with different headstamp.
In my view,this guitar produces a loud full tone due to the quality of the spruce used for the top and attention to detail shown by the luthiers from japan who crafted the necks by hand and only used completely seasoned woods during construction,making a budget guitar from 50 year old components,i bet the folks at martin were impressed.
good on ya

I own a mid-90s dr28-h copy. think it was a special edition, with the herringbone inlay. absolutely terrific guitar, virtually indistinguishable from martin equivalent in sound and feel.

whenever i mention it to knowledgeable dealers they stress that it will hold its value and try to convince me to part exchange it for whichever of their guitars i'm interested in. i paid about £500 for it in (i think) '96, though i think the guitar was a couple of years old at the time. it plays much better than a lot of more expensive models (including newer martins).

of course quality will vary from model to model, year to year, but personally i wouldn't part with my sigma. seriously worth trying out at least if you are looking at martins- if the brand isn't important to you, you can get an older, played in guitar for much less than a brand new martin and still with that martin feel.

C.F. Martin has discontinued the Sigma line of guitars, as of about two years or so ago, so I was told. If there is one out there to be had, in good shape and a good price, I recommend you get it.

Sigma Guitars are made by Martin Company no finer guitars are made .
The top is probably made of Sitka Spruce an the back and sides are
made of laminate mahogany. The fret board can be made from any number
of hardwood as long as it meets the standards of the Martin Company.
Check the guitar make sure it is not damaged in any way.The neck should be streight with no bowing up are down .
Play the guitar before you purchase . The sound quality should be clear and clean.

Excellent information. I have a Martin sigma DR12-7 with a repaired cracked neck from an airplane ride to Houston several years ago. I paid $100 for it about 10 years ago. I has been repaired but has not been strung for quite a few years. Do you think it will still hold a tune? Thanks again for all the great information.

I have not seen much about the DR1-ST. I just bought one for under $100. It sounds fantastic! Great sustain and low action. It was converted to a lefty prior to my purchasing it so I jumped on it since I'm a lefty and decent used lefty guitars are hard to find. Pickguard was removed and not replaced. This one has the paper label with serial number 707026 and says Made in Korea. Any clue to how old this might be? And any other info would be great too. Thanks.

I thought it was about time I added to this sigma fray. About 20 years ago I was teaching my brother how to play guitar (no I didn't charge him though I thought about it;) and having only one guitar at the time (Alvarez model 5227)it seemed only prudent to purchase a used guitar with reasonable sound at a better than reasonable price for him to learn on. I came across a 1980 Sigma Anniversary (anniversary on the 20th fret)with some minor fret wear on the third fret, the cost was in my neighborhood - $75.00. After playing, it quickly became one of my favorites (I only had two). Long story short, When he got married I gave it to him as a wedding present - He still owns that marvellous guitar. Since then I have been fortunate enough to purchase two (2) more anniversary guitars on ebay. One purchased in 2002 and the other more recently. After I replaced the plastic saddles with bone saddles the guitars just rock. There is no doubt in my mind these guitars are hands down some of the best made acoustic guitars. The tone is brillant, the neck remains straight (30 years old)on all three of these guitars. My brother and I now know how lucky we were to stumble across one (let alone three) of these guitars thanks to Sterling Webb. Big shout out to Sterling for his painstaking research and willingness to share with all of us Sigma fans. I am proud to say, as it stands, my family owns a full 3% of the market of Sigma Anniversary Guitars. Now if I can just find where the other 97% of them are hiding......:)

HI Carl thanks for the offer but I dont really think I could part with the Tram we have been too much history.

The Sigma guitars to go for are the ones made before 75 as they were made from very high class woods, the stock ran out about this time and Sada san the old man who founded the factory in Nagoya was bankrupted also about this time. Im not saying that the Korean ones are not good value for money but the ones from this era are fantastic instruments.

I bought a new Korean built Sigma 000-18 in the early '90s (serial number starts 9308, the rest is obscured by the 000-18 stamp but might end 0092). Although cosmetically it is not perfect (the body end of the fretboard is badly finished) I've had no complaints about it's sound. I bought it from a shop owned by a local Luthier who was extolling the virtues of these guitars for their price.
From what I've read these guitars have a solid Spruce top (mine definitely has)& laminated mahogany back & sides. Mine (chosen from 2 in the shop at the time)has a flamed maghogany neck and a fine chevron flamed mahogany back (split from the centre seam outwards). This is not some photo-flame effect which they apply to cheap electrics, as the flame moves as you tilt the guitar. The flame is visible on the inside (back) of the body as well, although not matching the direction of the pattern on the outside. What I don't understand is why they would use flamed mahogany on the inside of a comparatibely inexpensive guitar !

For information (for those interested in current prices) - there is a Sigma DR41 for sale in a local guitar shop for £299.00

Proto.....Here is a paste from way up this thread from Stirling Webb,a well advised contributor. He has not responded in a long while so I fear he is no longer with us. AS FOLLOWS............... "Also made in small numbers in 1979-81 were Sigma models with the prefix 52S, as in 52SDR-7. Curiously, they are made entirely from some very strange laminates. The 52S series were sold as "professional" instruments; they have a pure clean resonant tone (like a high-end maple Gibson) which combines well with the human voice and records cleanly without a fuss. (I've had three of these, and all had thoroughly rigid construction, dead straight necks that had not moved in 25 years, low fast action, and great playing ease, as well as fine sound.)

I bought my sigma CS2 in the late 80's, new with a black cardboard case for $138. I have used it for many years at campfires with the Girl Scouts. I started taking classical guitar lessons and my teacher told me I needed something better to improve. I got a R3 Ramirez with a hard case for 6 times the costs. I kept the CS5 but bought a Alvarez steel string for more volume at camp. And I wonder how I ended up with 7 guitars! Now down to 5 after selling one and giving another to a student of mine.

amgis80      S is for solid TOP    the earliest Sigmas were made of both laminate and solid tops but neither carried the S designation. You just had to look real hard to see what the top was made of. the S came sometime later as they moved to all laminate construction, then it became a premium. There is no set rule though as the strangest thing. show up!   Your D-10 is all solid

I'm glad to have found this Sigma thread. I have one of the elusive Sigma D-10 Anniversary models (serial # 815924). Received it as a Christmas gift in 1980. Thirty years old and going strong. Always knew it was beautiful in looks and sound, and would never part with it, but until recently I did not know the backstory of the D-10 and the desirablity of this great guitar.   

I do have question, but it is about the SDR-28 versus DR-28. I recently purchased a Korean (1993)SDR-28 (serial # 93060187). My initial understanding was that the "S" in SDR stands for "solid" spruce top, but my understanding is that the DR-28 of the same era also had a solid spruce top. If both of these models have solid tops, then why the extra "S" in SDR-28? From discussion on other sites, most folks describe the SDR-28 as having laminate back and sides (like the DR-28), but then exactly what does the "S" stand for? I've wondered whether the S in SDR means solid body, too. Wishful thinking? Anyone know?

Zach The top may or may not be solid, check the edge of the soundhole for clues as to whether it's laminated. Back and sides will be laminate. You really need to play it with a fresh set of strings and compare it to similar sized guitars to know. If you like the sound that is the real question, if you do grab it.
Look for a flat top/solid bridge connection/straight neck/action and if thes is enough saddle to modify, and other structural issues.

To Guitaaress,   Shame on you , you didn't do your homework therefore you are commenting on something you shoudn't because you lack information. No worries, we will educate you. There were Sigma models made at the Nazareth plant. The DR-28N and the DR-35N are 2 of them. The N suffix tells us this. Taylor, Santa Cruz and Collings are good instuments but not everyone can afford them Your comment on the Sigma brand..."they are excellent value if carefully chosen as the quality varies greatly"....applies to ANY mass produced brand at any price point. Tonal deficiencies appear at ALL prices, I own and have owned and played/recorded Martins and Taylors. My Japanese DR-7 competed with these guitars on many occasions and performed very competently.
I have read this thread from top to bottom and I have yet to read a post stating these intruments were renuine Martins.
What I have read is that there are many owners that tested their Sigmas agaainst the big dollar brands and couldn't justify the huge difference in cash for, at times a minimal gain in performance.
Your 76 tour to Martin enforces the claim that all Sigmas were setup and inspected in Nazareth before being delivered to the dealers. Thank you for that.
Please don't be a "brand snob", spend some time reading this thread.
You will learn a lot.

I toured the Martin factory in 1976 and saw literally piles of Sigma guitars at the factory that were inspected restrung and sold to Martin retailers with CF Martin backing. Any idea that they are anything but imitations of the real thing ie genuine Nazereth made Martins, is fanciful. But as Leadfingers points out they are are very workmanlike instruments.
The tonal deficiencies will be exposed when you take a Sigma into a recording studio and discover the absence of the extended harmonics that are the halmark of genuine handcrafted Martins and the other quality makers like Taylor, Santa Cruz and Collings especially. But as a budget instrument that plays well and does the job they are excellent value if carefully chosen as the quality varies greatly.

To Rick with the DR14.

Rick, I am allmost positive that all Sigmas imported and sold by Levin was all laminate. I have had that information first hand from people with background in the Levin company, and it is also stated in the Sigma catalogs distributed by Levin.

Levin had their own people sourcing instruments from Japan, and in the beginning they were sold under the brand name Nippon Best. Nippon Best were available in both Gibson style and Martin style. Later they branded all Japanese import guitar Sigma, and there were still models starting with SG which had a typical Gibson shaped headstock. These are the only Sigmas I have seen which does not have a Martin shaped head.
One example here:
http://www.vintage-guitars.se/1970s_Sigma_SG-9_black.jpg

For those thinking all "greek-Sigmas" have solid top, I can say for shure that my greek GCR-7 (sideways M and zerofret, and adjustable bridge) is all laminate. I have reset the neck and inspected the wood under the fretboard carefully, there is no doubt.

Still a great sounding guitar.

I see this is an old thread, but it was still great to read so much information about the history of Sigma guitars. I have a DR-15 with a S/N of 35089 that I bought brand new in 1978 in Harrisonburg, VA. My DR-15 is pretty much the same as Bob Spradlin's except it does not have abalone inlay around the hole. Mine has alternating black and white inlay around the hole.   

I had contacted Martin a couple of years ago to see if I could get any information about my DR-15. The representative at Martin told me they didn't retain serial number records for Sigmas, but noted the DR-15 model wasn't produced by Sigma until the mid-1980s. It's good to know someone else purchased one in 1978.

My eBay finger got the better of me & I bought a Sigma CS2 classical guitar.

I'm interested to find out about how when it was made & if the CS2 is regarded as a good instrument.

The label inside says "Sigma Guitars, Est. 1970, C F Martin Company, Model CS2, Serial No: 890900024, Made in Korea".

It is in very good condition & has come up nicely after a clean & some lemon oil on the fingerboard.

As for my own perception of the CS2, it seems to be a pleasant instrument to play, although it feels very different from my "everyday" guitar (A Santos Martinez SM44). However, each time I play the Sigma I get more used to it. I am intending to use the Sigma for guitar pieces that use non-standard tunings (I am learning a couple at the moment) without having to disturb my main guitar. At least that's my excuse for having 2 classical guitars ;-)

Stefan, Glad you got a chance to see that ebay listing. The real answer to the identity of the guitar I believe was under the soundhole label the dealer had applied. I did send a note to the seller asking if he could see any clue of a stamping. He said he would look and get back but that didn't happen, no surprise. He also did not post my question. There is a very good chance the new owner uses this forum, so we may find out in due course.
Look forward to news of the database, a good idea.
I also am interested in MIJ guitars.
I have 4 Hohners, 3 Suzuki's, 1 Aria, all acoustic. I have 2 acoustic and 1 electric telly copy NORTHERN brand guitars that were made in japan for the Canadian market, info on these is virtually non existent. They are easily identified by the maple leaf on the headstock. My best guess is Hoshino made but I think the electric could be Tokai, high quality stuff.
My DR-7 is MINT and my best player.
My 65 Harmony Rocket and 66 Harmony Bobkat, and Seagull SM12 round out the collection.

My other Japanese collectible is my 1977 Toyota Celica GT Liftback.

Hi Neil,
I just had a quick look at that "logo-less" DR-7 on eBay, and although I'm of course by no means an expert on Sigma guitars - I just started to learn about them a bit more, also courtesy of the various contributors of this very thread - my "gut feeling" somehow makes me doubt that this is indeed an original Sigma...

For me the key indicators are the fact that it simply doesn't have a Sigma logo on its headstock plus its internal label doesn't mention that it's a Sigma either (and I've also never seen a Sigma yet that had a label that looks the same as this particular one), so I'm inclined to think that this is not a Sigma DR-7, but who knows (as the variations of this brand are seemingly alarmingly endless)...

I've now somehow become quite fascinated with those old Japanese-made Sigma's, so I decided yesterday to create a little database (in MS Excel format) for myself (and maybe some others will be interested as well one day?) & attempt to bring a little "method to the madness" here...:)

My "Sigma-database" will exclusively consist of Japanese-made models from the 70's (so the original Sigma line), and I've decided to add as many as possible data - as found on the www - to it (currently based on 23 different categories, e.g. model name, adjustable bridge or not, type of label, body material etc. etc.), and in this way I'll hopefully be able to get a better understanding of the many existing variations out there of this fascinating brand...

Neil, the spelling of "The CF Martin Organisation" with an "S" was actually implemented in the second half of the 70's by...the Martin company itself, believe it or not.

I've seen literature/brochures by Martin from the 70's where they used this name, and apparently the reason why they decided to use this spelling was simply because Martin's management at the time thought that "The CF Martin Organisation" had a somewhat more "wordly" and international ring to it...:)

I read somewhere that only the very earliest Sigma's had this particular paper label (and this sounds quite possible, considering the low serial number of this example), however note that the Sigma that was for sale here until last week had an even lower serial number (4747) yet had the same type of label as my example...

Stefan, You're going to drive yourself nuts trying to make sense of this brand. Yor fingerboard is most likely "ebonized" rosewood, a fancy way of saying "rosewood stained black". You will likely be able to see the rosewood grain pattern if you study it closely. This technique is widely used in guitar manufacturing Looked at your photos. Nice guitar! Looks as though it could have been made at the same location a my DR 7. I see a lot of similarities to the Tokai(Cat's Eyes)guitars that makes me think some Sigmas were made there. It's very likely there were a few Japanese plants under contract to make this brand that explains the difference in finishes/labels etc. I was interested to see your label quote"Imported and inspected by the CF Martin Organisation" in an above post. Organisation with an s instead of the American OrganiZation, Wonder what that signifies? Probably just a British influence on the Japanese.

1. the end of the fingerboard of the GCS-6 with serial number 5628 that was recently sold on eBay has a rather prominent curve, whereas the fingerboard of my example does not have this curve;
2. The headstock and the neck of the Sigma with serial no. 5628 have a GLOSSY finish, whereas the finish of my Sigma's headstock & neck is matte;
3. All Sigma's from the early 70's that I've seen so far clearly seem to have a rosewood fingerboard and bridge, but oddly enough the fingerboard and bridge of my Sigma almost appear to be made of EBONY, as the wood has a really dark (almost black) appearance...

I made a few addional observations about some of the earliest Sigma guitars, based on pics I've seen that were posted on recent eBay auctions :
- there were obviously different internal labels used on the early Sigma models; a Sigma GCS-6 with serial number 5628 (and which featured an adjustable bridge) was recently sold on eBay, and this guitar's paper label is quite different than the label of my example; this guitar's label bears the text "Imported and inspected by the CF Martin Organisation", whereas the label of my GCS-6 (which is only some 600 digits away from this one) does not have this text; the tuners of this example are b.t.w. also different than my guitar;
- Another GCS-6 with an 8-digit serial number (starting with "73") that was listed on eBay a while ago also has an adjustable bridge (plus the old SIGMA logo) but had exactly the same label as my guitar...
- Then there was a Sigma DM-5 (with serial number 4747) for sale here in the Netherlands until last weekend, and this model had the same features as my example : the "old" Sigma logo in big bold letters, non-adjustable bridge, no zero fret, the same paper label as my example & its serial number was 4747...interestingly enough its owner stated in her ad that she had bought her DM-5 NEW in 1981, and the previous owner of my GCS-6 told me that he had bought the guitar ALSO around this time, and it was new as well...

So, it appears that there's indeed not a lot of consistency here when looking at some of these early Sigma's...:) serial numbers of examples that were made in the early 70's are completely different (4 digits vs. 8 digits), most appear to have an adjustable bridge but some don't, then there are different internal paper labels etc..
Could it be that these earliest Sigma's were simply made by different manufacturers in Japan at the time, which could explain these differences?

Stefan,    6260 should be an early model. Does the guitar have a "zero" fret? That is a fret very close to the nut (approx 3/16th inch. That is a good clue that it's an early one. Most early Sigmas will have the adjustable bridge but not all,depends when the stocks ran out and where it was made. I will take a fixed bridge anytime over an adjustable. As Iv'e said before, the only consistent thing with Sigmas is inconsistency.

Hi,
there's some pretty interesting info so far in this thread about Sigma guitars, that's for sure!

I hope one of the experts can help me with the following question as well : I've got a GCS-6 (bought for approx. US $90) since last year, and its serial number is 6260;
Based on this serial number (plus the fact that it has the original "Sigma" logo in gold block letters) I'm assuming that it must have been made in Japan in the very early 70's, however what confuses me is that it does NOT have an adjustable bridge, which apparently all of the earliest GCS-models by Sigma should have...

So, is there any way of finding out if my GCS-6 is a really early model, or is it simply a fact that the serial numbers of those Japanese-made Sigma's from the 70's don't have any real consistency?

Thanks for your help!

Hello, Multiple Sigma Owner,

I just wanted to let you know that at least some of the 52 series Sigmas have solid tops. I have a made-in-Japan 52SDR-9 which I purchased new in 1977, and it definitely has a solid spruce top.

My particular guitar has a laminated 3-piece rosewood back and sides, with white ivoroid bound top, back, fingerboard, and headstock. The greek "sigma" letter (sideways M) is inlaid on the rosewood covered headstock in MOP, with "SIGMA" in gold capital letters below it.

The rosewood fingerboard has inlaid MOP "snowflake" position markers, and the headstock is covered in rosewood veneer. The enclosed tuners have octagon shaped covers, and are silver in color.

This sound of this guitar has continued to improve with age, as would be expected with the solid top. I played it side-by-side back in '77 with other guitars of comparable price, and it sounded better by a significant margin. Not as good as the D-35 Martin I wanted, but definitely not run of the mill. It sounds better, in my opinion, than many of the lower end Martins of today, and at any rate, I would never let go of it because we have been together for so many years now.

Well I just aquired my 2nd 1980 Sigma Anniversary mod.10. It is in very good condition, about a 9 in a scale of 1-10. My first one has brass nut, saddle, and pins. This one has Tusq saddle, pastic pins, and nut?
It was very dusty when it arrived, but after a good cleaning and some Gibson polish, along with a new set of strings,WOW what a great guitar these things are.

Just a note to express my thanks and admiration for the amount of effort and even scholarship that has gone into this thread, and for the information I've gleaned from it. I own a Sigma 52SGCS-4, serial number 25569, which I bought (I think) in 1979-80. Like a lot of players, I bought it as a cheap alternative to the higher end models. I played it for a while, but gradually moved on up to other, different and more expensive guitars. I basically abandoned my Sigma and it eventually was picked up by my teenage daughter. She and her friends horsed around with it for a time, but she eventually just stuck with her violin and left it alone. It sat in a corner of her room, uncased, unplayed and unloved for probably five years, essentially gathering dust. Not a case of abuse, exactly, but certainly neglect. When we decided to renovate our house, I retrieved it and decided to spruce it up and try it out. I cleaned it up, oiled the fingerboard, re-strung it and adjusted the action (a slight lift in the strings was the only structural change that had occurred in all that time of inactivity). I was astonished! It sounded beautiful and played with more ease and fluidity than far more expense guitars I had tried in the intervening years. It was like running into an old girlfriend, finding out she was as gorgeous as ever and . . . well, we won't go there. Let's just say I fell in love all over again, discovering qualities and charms I was too unevolved to see before, and now it's my acoustic of choice. Viva Sigma!

RE: C

When I purchased my Sigma SDR-28C in 1989 I was told that the S was for Solid, the DR was for Dread-Rosewood with rosewood sides and the C was for Cedar top. I could be wrong, but mine does look more like cedar and sounds much more mellow that a spruce top.

Odd to put cedar on a dreadknot, but I believe this to be true.

I am very happy with mine after 20 years. It is nowhere near the HD-28 LSV we also have in the house in terms of sound, but far beyond any sound that I have gotten from any guitar for less that $2000.

I have a Sigma DM-4 that I purchased brand spankin' new back in 1980 at the Guitar Center in Hollywood. After reading some of the previous posts I'm a little perplexed. It's been stated paper labels were phased out around 1979 and that Korean production began around 1984 or so. My DM-4 does have a paper label but it also says "Made in Korea" on the label. I bought this guitar in early 1980, so it could have been some leftover store stock from 1979. The top and back appear to be solid (I'm still trying to determine if the sides are also). The serial number does have a "79" in it but who knows if that indicates a production year. It also has the "1970" headstock decal and no sideways M. Based on this info it seems that the Korean manufacture of these guitars likely started much earlier than the 1984 date that has been discussed. I'm also wondering if during this transition period that some of the solid wood stock that was used in Japan was ported over to the Korean plant until it was exhausted and replaced by laminates later on. Any thoughts or comments from the Sigma experts?

I just picked up a Sigma that someone tried to disguise - they scraped of the headstock logo, blacked out the Sigma stamp on the inside and tore out the label. I can see that it was made in Japan and the serial number is 526649. It's a solid spruce top with a black pick guard and thick white binding with an thinner black/white/black/white/black inside of the thick binding, and the sound hole has a triple ring of black and white. The back and sides are rosewood - I can't tell if it's ply - and the two piece back has what looks like a maple and rosewood checkered inlay. The neck is rosewood with dot fret markers. Any ideas as to what I got or how old it is? I just brought it home and am about to restring it, but even with ancient rusted strings it sounds pretty good.

Thanks for any help you can give.

Hello, I have a acoustic cutaway Sigma guitar made by Martin. It says it was made in Korea for Martin & Co (Stamped on the inside). I'm assuming somewhere after 1984. I was wondering what info you could give me on this guitar. Year it was made and if it is a rare guitar or vintage? Can anyone send me perhaps a link or pictures of an old catalogue (pdf) file or something with pictures and info? Looking through the sound hole on the neck block there is a number stamped. Looks like 803134. The first #8 is hard to tell if it is an 8 or maybe a 3. Looks more like an 8. There is another number stamped when I look directly straight down into the sound hole (NOT on neck block). This number is 249332 and there is also(separately)DR-3C. I can't find anything on a DR-3C on the internet or in any books. I thought maybe it was DR-30 and not DR-3C but after taking a realy good look with a flashlight it IS DR-3C.(very odd). Unless it is a perfect half print of the number 0 but sure doesn't look like it. This thing sounds amazing. Any info would be greatly appreciated. Thanks

Joseph & Teawhy,

Not sure you're going to get much more information here than what is already posted. There just isn't much out there related to these guitars.

The guitars are worth what you can sell them for, and I don't mean that to be flippant. There just is no guide. The "most desirable" after the d-10 are the early dr-7's that were made in Japan. They "top out" at under $500 for a dead mint one, mostly, but there's always an exception. Without seeing your guitars and playing them, I have no idea. $200 - $300 is probably typical, maybe. Japanese typically bringing higher value than korean.

Joseph, the closest you'll come to a date, is a "range". Here's the best guide I can give you.

If it has the greek sigma headstock, with the sigma symbol that resembles a "sideways M", it is pre-1978. Most likely then a 1977 as the serial number is fairly high. (then you have to assume that they were numeric and there is little evidence of that but it's logical). If it has the "established 1970" headstock, it is 1978 or newer as that began the "second generation". We know this from looking at and collecting old advertisements.

It seems that if it has the "1970" headstock and a paper label, it is most likely 1978 or 1979, and if it has no paper label but a branding on the back brace it is most likely 1980-1984 if it's "made in Japan". Korea production started after that, and is typically thought to have ended around 1988, when it moved to taiwan.

Hope that helps, not much more to say, I'm afraid.

Thanks -

Hi, I've just aquired a Sigma DR-7 and I'm trying to find out a bit more about these guitars. The one I have has the sideways "M" on the headstock, adjustable bridge and seems to be of all laminate construction. It came with the original hard case and inside is the factory inspection certificate with the test played date showing 47.12.27. I believe this dates it to 1972 (the 47th year of Hirohito's reign) although the seriel number begins 74----. This certificate also states that the guitar was fitted with "light" strings which I'm assuming means 11's. The questions I have are: I've read on here and on Wiki that DR-7's of this era are all solid construction so why is mine laminated? Also, I cant find any information on the material used for the neck. It looks too light to be mahogony and is more like a teak colour with a very deep ebony? fingerboard. Any info would be appreciated. Finally, the action is quite high, despite little neck relief, a low nut and low saddle. I cant detect any raising of the top, so it looks like thats how it was meant to be. Is this true of all of these guitars? Any answers or info would be really appreciated!

I Just listed this 1974 DR-7 on eBay if anyones interested.
Auction #220461866200

***************************************************

Just picked up my first Sigma - a DR-7 with Rosewood sides and 2 piece back and looks like spruce on the top. The serial number is in the 11,000's and it's the original style with the paper label and the sideways M on the head. Probably '73 or so?

Someone was giving it away on craigslist . . I happened to just be in the right place at the right time - the woman who owned it told me the strings were too far off the neck to be played, and a local music store told her the neck was warped and couldn't be fixed.

Anyway, it ends up that the top is just bowed out a little behind the bridge and the neck isn't warped at all. Probably has been leaning on a wall for the last nn years with some Black Diamonds on it.

It sounds as big as a Martin and the workmanship is just fine.
I remember when Martin came out with the Sigmas. They didn't really strike me as being a "low end" guitar and were priced along with the high - mid range instruments. I mean - I bought a Martin D 12-20 for a little over $300 and the Martin D45's could be had for just over a thousand bucks at the time.

I buy and sell guitars mostly, but after looking at what these are going for on eBay (200-300) I might just keep it. There is not a guitar out there anywhere right now that has the quality and big sound that this has for less than a grand.

It has, "Sigma Guitars Est. 1970" at the top but no other defining marks.
He won this guitar in a raffle sometime in the late 70's or early 80's I'm pretty sure.
He used it as a spare guitar in his country band so it wasn't used a lot.
It is in great condition and sounds great.

I've been playing for 15 years, and bought a 1973 DR-7 a year ago from its first owner, with S/N starting by 73XXXX. I love the feeling of this guitar and will take good care of it to keep it forever.

Its plastic nut was dying from aging, it had a adjustable bridge with 2 metal pins on the extremities. All laminate, but with very nice woods, i believe the sides to be brazilian rosewood, color is really chocolate and veins are stunning. Back is more red, so probably indian rosewood, with a dark part, probably meaning it was taken from the center of the tree, which as i've read is a very good point. Spruce top is with very close veins. Visually all woods are exceptionnal and no crack at all. It has crappy tuner. I wonder if the all laminate construction isn't making this guitar even more martin voiced than a martin, if that makes sense to anyone.

I had nut replaced, and adjustable bridge removed and replaced by tusq directly in contact with the table, action was high so bridge was a little shaved down too, all done by a luthier. I later had a seymour mag mic installed in it and changed the pins (4 low to tusq, 2 high to ebony). i'll soon change tuners and fit a strap pin on the basis of the neck to make it fully playable on stage.

One important fact the luthier told me is that the frets are probably glued with epoxy as it was usual at this period on cheap guitars, which could make replacement of frets very hard. Any feedback on this point from other sigma owners is more than welcome as it could be a serious drawback on the sigmas.

I put martin red SP on it, don't put lighter strings if you want to hear the wood sing. V shaped neck is a bit tricky at first. This guitar is hard to play and needs to be attacked heavily to give its best. I would not advise it to a begginer but consider it like a pure gemn, especially for my muddy pentatonic blues style.

Been lurking this forum for a couple of years- I have an SDR-28H that I bought new in 1987 or 88. Love that guitar- changed the saddle to Tusq, and I believe that it can go toe to toe with many of the martins in my local guitar center (and most of the Gibsons and Breedloves...and some of the Taylors...) But I bought a D10 today and it blows away any other acoustic I've ever owned.   The price? $200. Yes, it has a few battle scars on the spruce top, but no cracks whatsoever, neck straight as an arrow, almost NO fretwear. Yes, I feel incredibly lucky.   Previous owner bought it new and had a martin passive pickup professionaly mounted under the saddle about 9 years ago. I also own a 1937 martin 017- (nyc stoop sale- $90!) and a 2005 Taylor 210e- nice sounding, no-frills solid body player. The D-10 is now hands down the nicest guitar I own.

To Pierre    I once had a friend in the 70's that owned a GM car. The name on the front was "ASTRA" (Pontiac) but at the back it read "VEGA" (chevy)! I think you have the luthiers equivalent. The factory either attached a Tokai neck to a Sigma body, or picked up the wrong branding iron by mistake. It certainly gives strong evidence that Tokai was a manufacturer of the Sigma line. I have always thought my early DR-7 could have been made there.
A very unique instument of obvious high quality.

Hi "Multiple Sigma Owner"

Thanks for the reply - I had suspected the same thing at one point -and I had heard the same claim - that maybe tokai was the manufacturer for sigma at some point. I have searched online catologues that date from 1975 to 1984 from Tokai and have not found a guitar that I can confirm as my model (especially since mine has the "sigma" logo stamped inside).

To be more specific - the head of my guitar has a "mother of pearl torch inlay" - its not spelled out "Cat's Eyes" like the Tokai Guitars (although some Tokai guitars have the same logo).

Any further help would be great!

Pierre,

I think you've got a Tokai guitar, not a sigma, though there are some who claim that Tokai was one of the manufacturers for Sigmas when they were made in Japan. They manufactured, and still do, a guitar called "cats eyes". Early ones were made in the Japan factory, and also some were made in Korea.

I don't know much about them, but the guys at the tokai registry sure do. They love them over there too. Bet you'll find your model there along with a year from their serial number database.

Good luck!

Wondering if anyone has ever heard of this Sigma model which I bought from an old family friend!! She said her husband had bought it a "guitar" show in the early 80's.

I have been told by 2 local shops that its a solid body rosewood (vertical bracing on the sides) with a solid spruce top (the grain matches) - they had never seen a Sigma that looked like this.   The original warranty paper says the Model Number is s2000 ("2000" is stamped on the inside) but I think its a mistake, there is no other identifialble model number on the guitar -it has the body of a D28. The serial No is 1390581.

The inside is also stamped with "sigma guitars made in Japan for Martin Co", but the headstock does not have the sigma 'logo' rather a "Cats Eyes" inlay. It also has inlay snowflake/diamond position markings on the neck, inlay around its body, and around the sound hole.

At first I though it was an Anniversary Sigma made by Martin but the descriptions in other postings don't match. Any information you could provide would be greatly appreciated. I can provide photos for anyone who is interested!!

Thanks,

Pierre

Richard,

DR-9 just sold on ebay for $432.50. It is very similar to the way you've described your DR-11. Has the 3 piece back. It is stamped on the back brace, so that would indicate 1980-1984. IIRC, you indicated yours was earlier than that, but it is still made in Japan.

Brought some pretty good money, I'd think. Whoever bought it got a very nice guitar, and whoever sold it got a very good price for it...

Richard,

My experience has been that they're worth what someone will pay for them. Sometimes it is a lot, sometimes, not very much. People either love them or hate them.

I happen to like them, and have 5 of them, but others see them as an inferior Martin knockoff.

A few months back, I saw a Japanese DR-15 which is similar to yours sell for $450 on ebay, yet, a couple of months ago, I picked one up (also Japanese) in a resale shop for under $200. You just never know. This one had an annoying open fret buzz on the high "E" at the 3rd fret. I knew it was just dry and needed humidification. 2 months in a hardshell case fixed it and it's PERFECT now.

Honestly, if it were me, I'd keep it. But, hey, I understand the quest for a Martin. I've got a 000-15S which I bought new 3 years ago. Love the look, love the 12 fret, but honestly, while it's a better guitar, it's not "that much" better. I'd not sell it, and I play it often, it is different than my Sigmas. Better construction clearly, but it takes a discerning ear to hear the difference. If you didn't know what to listen for, you wouldn't hear much difference.

Hope that helps.

Hello Again,

I posted several months ago inquiring if anyone new the going price / value (these might be different!) of a late 1970's Japanese DR-11 (solid spruce top, three piece solid rosewood back, and rosewood sides)?

I've had several folks / musicians look at it, and tell me it's a "keeper," and it continually sounds better than just about every new top shelf Martin, Taylor, and Gibson I pick up.

Hey Multiple Sigma Owner, you are right! A guitar collector buddy was over and confirmed the solid spruce top on the gcs-6. He owns a Martin 000...same guitar the gcs was meant to emulate. He pointed out the wood grain. Evidently the grain is optimal if it is tighter in the center of the guitar, and should fan out in to wider grain patterns. My Sigma has the desired pattern. A couple of things he noted that separate the Martin from the Sigma were the cheap tuning keys, the lack of scalloped bracing, and the not-so great "rosewood" stain finish on the mahogany body. He said my 35 year old ax has a straighter neck than my 2 year old BR 160. Then, to top things off, I see somebody has a 6 on ebay currently, and they're asking over $400. As indicated earlier, you can ask whatever you want, but clearly the early/mid-70's Sigmas are something special.

The CFM-2RTT Sigma was a for runner of the Sigma SE Series in the late80S early 90S. In 1992 it was cataloged as a SE-40T. The guitar was
constructed with a Sycamore top and was avaliable in
Burgandy,Blue,Black,and Tobacco Sunburst. There is no record of

Fret nut,
Pardon my 2 week response time. Since my DR-28C is the only Sigma I've handled or seen, I can't ID any custom features. To answer your question, no, it has no abalone purling or inlay. I asked a few of my friends if they thought anything about its construction was other-than-expected. Nothing seems truly unique. I got several positive comments about the materials. It's a solid, tight-grained Sitka top with rosewood back (2 piece) and sides. The Yamaha, Strat and Taylor owner likes the volume and looks. The Yamaha and Simon&Patrick owner says it plays really nicely, it's pretty, and louder than both his 6 and 12 string S&P's, which have the satin finish. Someone made a comment about how nice the tuners feel. Oh well, the "C" designation remains, for now, a mystery.

Im using DR Rare phosphor bronze strings on the SDR-28. So far so good. I replaced the plastic pins with bone and brought down the action a bit by filing the bone nut. I also tightened the truss rod a little but found that as soon as I had "tension" on it my e string buzzed so very little relief needed. Shes playing nicely now, almost sings with tone so no complaints.

Yes, 895 sounds way high especially for the era. As far as I'm concerned these guitars are of exceptional quality. I lucked into mine second hand at 200.00, hard shell case included. The guitar was well kept and in near pristine condition. I changed out the saddle and bridge pins to "tusk" and adjusted the action down a bit via the saddle. This guitar gets a whole lot of second glances at the bluegrass jams (I'm a flat picker mostly).

For the time being I am using Elixer phosphor/bronze lights (I have the old acid skin problem lol). I tried Martin bluegrass strings a while back and really liked the sound for bluegrass but just couldn't make them last. D'Addario strings were also good and bright but again dead in short time. I'm hoping to find a coated bluegrass mix of strings in the future. BTW, I really like the tonal qualities of Elixer strings - have you tried them yet?

I'd be interested to know what strings you find best and your style of playing.

Hello again learned Sigma owners -

I now proudly join your ranks as I've added a Sigma D-10 to my tiny collection of instruments. I'm so proud to report that I was able to negotiate a reasonable price on a recently mentioned Anniversary model. It has its share of battle wounds, some mentioned in the description and some conveniently left out, but with the beauty in my hands, I feel that I made a fine choice in the end. The sound, in general, is as described by other D-10 owners -- well balanced and very clean, favoring the crisp, treble side but possessing its own deep, mahogany foundation.

Thanks to those here who have provided such thorough commentary on these Sigmas, whether it was highly subjective or coldly objective or somewhere in between. All of it helped inform my ultimate decision and I am indebted to the forum for the guidance nonetheless.

So, add one more to the circle...

Proudly and respectfully,

Cutter,
Thanks for the response. Mine is a solid top as well no question. The construction appears to be very solid. Ive ordered some bone bridge pins to replace the plastic ones, and I need to work on the action a bit from the new nut installed. But other than needing some tweaking on the setup its a great sounding guitar.

The original owner swears its at least 20 years old, bought in the late 80's in Austin Texas. But with the serial starting with 91 I figured this was pretty close to meeting what he remembered as purchase date.

Doesnt $895 sound a bit high for buying new in that time period? Apparently it was marketed as a very high quality guitar.

What strings do you have on her?

Sounds exactly like the SDR-28 I got awhile back. Not sure on the nut but you should be able to measure it and find the specs on the new one. Contrary to some of the stuff I've read, mine does have a solid top. When I look at the sound hole cut out it's very easy to see the wood grain from top to bottom. Love mine, wouldn't trade it for the world. I'd put it up against most of the newer DR-28s I've heard.

Oh as for the serial no. - It's anybody's guess on these (just my opinion).

Enjoy the guitar

I traded for a mint condition Korean SDR-28 yesterday. The serial starts with 91 but the guys swears he bought it earlier that that and paid about $900 for it. That amount seems high but he actually had the original price tag in the case.

--Can I assume with 91 starting the serial number thats its a 1991?
--Also, for those with dr-28's, whats the brige pin and saddle sizes? I want to upgrade to bone but want to do it myself. Should I go by the pre 1994 Martin specs of a 2A bridge pin?

To Dana    If yor guitar wears a "C" and is not a cutaway it probably means " custom" in Martin speak.
That will mean it could have abalone binding/purfling on the body/neck/fingerboard or all. Is this the case, or is there any other feature that is not familiar with Sigma's?
There are Sigma's that sport an "H" after the model # that signifies "herringbone" binding like the Martins.

Hey all you SIGMA lovers!

I have a sigma DR-7 I am planning to put up on Evilbay (E-bay) : P soon. I ran into this forum, read a ton of posts, and learned a lot.

Maybe someone on here wants first crack at it.

It's an Early 1970's SIGMA DR-7. It has the old style headstock and with the sideways M. It also is stamped "as it fits" concerning the model and "made in japan" stamp on the label inside the guiar as others have talked about and indicates a early MIJ.

Serial number is in the 9000's, so it's rather low.

Just to keep the interest going, I've just bought for a very good price from TradeMe (the Antipodean EBay competitor website), an oldie-but-goldie Sigma 12-string. So, I've been using all the info on this thread to try and date it.

Here are the specs: Headstock: is inlaid mother-of-pearl "Sigma Guitars est 1970", (no sideways M), which (I think) dates it at later than 1980; interior stamp says it's a DR 12-28 model, which makes the body style the dreadnaught D-28, top solid spruce and the back and sides rosewood (R) - and very nice they are, too, only a couple of very minor dings. I've polished it up with Martin guitar polish and the wood just glows with that beautiful patina that old guitars get.

One stamp on the back-brace; "Made in Japan for G.F. Martin & Co"; and a separate stamp for the serial number S46 82. Which places it as no later than 1984, when they moved production to Korea and went back to paper labels.

I suspect that these items may place it at around 1982, which was during the time they were using Martin body design numbers.

Anyway, for all that it's over 25 years old, the neck is as straight as a die, the action is low and sweet, the volume of sound you can get out of it is awesome and the tone sounds very nice. Also it has an under-bridge pickup (which is still working) so I can put it through my amp when I play with my church music group. I'm glad I got it!

Incidentally, IMHO, the reason G.F. Martin shitcanned the Japanese operation was that they were getting a bit embarassed by the quality of the products: this one certainly sounds well equal to any Martin 12 I've ever heard and probably sold for about a third of the price!

FretNut,

thanks for letting me know that. I've never seen an all wood sigma that was made in japan, and I've never seen one with a laminate top... so, that's one thing about Sigma's - there is NO consistency.

The Japanese Sigmas that I've seen used pretty good tonewood, even the laminate pieces are pretty good wood. So, I'd assume that it would fool many players. After all, it's all about what it sounds like.

There were several manufacturers in Japan, so maybe one of the builders used all laminates. The "52s" series are all laminate. They are really nice sounding guitars. were marketed as "professional instruments", and geared toward performers. Maybe yours is one of those rebadged.... Martin used that 52s series to test some of the glues and laminates that they use today on their lower end guitars.

I like to set up a few chairs in my living room, then make my friends sit facing away from me.

Then I play my 5 best guitars. Two are sigmas, one is a Martin, one Gibson, and one is a Thompson. Frequently they can't tell the difference, occasionally you'll get one who prefers the sweeter, clearer sound of the thompson, but all are amazed that the $400 Sigmas that I have hold their own against the Martin and Gibson and mostly against the Thompson.

To Dave E

If you look at the edge or the sound hole you can check to see if the grain goes through the thickness of the top. Follow a few different grain lines to verify. If its laminate you wiil be able to see the core material.
As far as I know Sigma did not try to hide the fact that they used laminates by "rolling" the veneer over to hide a core. You can use a mirror to check the underside of the top to see if the grain pattern matches.
Just so you know I own an early (sideways "M") Jap DR-7 all laminate that has fooled many seasoned players. I could also be argued that a laminate will stay flat longer given it's "stable" construction as it it not subject to the natural stresses of a drying solid piece.

Hope this helps

Thanks to the Guest who commented on my posting, and the "potential" clarfication about date. I need to do some work to find out precisely when I purchased my Sigma DR-11. I was pretty sure it was 1978 or 1979, but with the comments you provided regarding the change in lettering on the head from the Greek to the Est. 1970...hmm...got me thinking.

My dilemma, however, continues. I recently bought a Taylor cut-away 12 string--started first looking at the Martin's--so now am still looking to purchase my first "real" Martin (I have a Little Martin LXM), and will continue to look at their 6-string cutaways.

Problem is, my Sigma sounds GREAT, and I'm not sure I can justify keeping it AND purchasing another new guitar.

The bottom line is, that I'd like to know how much my Japenese DR-11 is worth! It's aged quite nicely, has only a few minor dings, and sounds better than many of the new Martins I've played...which of course probably leads some people to say "why do you want to replace it with a Martin?" Well...first, I want a cutaway, and second...I want to be a Martin owner...call it status, perhaps longer-term quality, maybe an acoustic electric feature...??

Still pondering in Bozeman...

Thanks so much for the info. That helps narrow it down a bit. Mine does not have the open back tuners. It makes sense that they were manufactured in different factories, since many of these posts have said that these older ones are all solid woods- mine is definitely not. It's difficult to tell but I think it's all laminates.

Either way the guitar is in really good shape the bridge is not separating from the top (I keep it stored with no tension in the strings) The previous owner had medium gauge strings on it when I got it and the top was a little bowed, but I changed them and it hasn't gotten any worse in the 25 years I have owned it

The wood and condition is beauitful, it has six strings and have no idea of a value, he says that he has maybe less than five hours of trying to self teach. He has never learn to play and our nine year old wants to learn but don't want him to ruin it, if it has any value to it.
Can anyone give me some advice?

Keith,

There is no reliable way to date Sigma's. Unless you've got a sales receipt (and even then you don't know when it was made, just sold), all you can do is guess.

Here's what I know.

Sigma started the second generation of guitars in 1978. I know some said 1980, but it was earlier than that. I've got a couple of magazine ads from 1978 that tout the "second generation". Since yours has the 1st generation logo, you can safely say it is pre 1978. Next, it has the zero fret. Typically, you'd expect that to be an early one. My 1973 DM-5 doesn't have a zero fret, so it may be earlier than that. Also, if your guitar has open back tuners, that's another sign of early manufacturing.

I suspect that the serial numbers were manufacturer specific, meaning that sigma had multiple companies building their guitars. Some early serial numbers start with a year (presumably) and then a dash, my 73 Sigma is 73-XXXXXX

Sadly, no one except Martin can tell you when it was made, and they aren't talking!

I forgot to mention in my first post- my DR 12-7 has the "sideways M" or Sigma symbol in perloid above the block letter SIGMA name. It also has the "zero fret" which I have not seen on any other guitar

I was wondering if someone could help me figure out when my Sigma 12 string was made. It is a DR 12-7 serial number is Z2914. It also says manufactured in Japan.

I've read through most of these posts and never seen anyone else mention the letter Z in a serial number. I bought it used in the early 80's and I don't think it has a solid top or back and sides.

It's been sitting in my closet for 20 years, and I was thinking about selling it, but I was hoping to find out a little more about it before I do

Thanks, Keith

Don,

I have the original sigma catalog from 1970. It doesn't say "solid spruce top", it says "spruce top". However, I have a 1973 DM-5, the 1975 GCR-7, and what I date to either 1976 or 1977 DR-7s. All three have a solid top. I am positive of that. The catalog also says "spruce top" for those.

If your Sigma is made in Japan, with the sideways greek sigma letter in pearloid, I believe it to have a solid top. The 1994's were made in Taiwan. A laminate top for those would not surprise me. On a Japanese one? Yes that would surprise me a lot.

Other than the 52s series (which are all laminate), Martin used these to test glues and such, I believe all Japanese Sigma's to be solid tops. I know some think that Sigma initially made all solid wood guitars, I've never seen one, and I've seen lots of them.

I've also got a 1980 Sigma D-10 (anniversary model) and I doubt that it has a solid back and sides. I'm not positive but fairly certain. Nonetheless, it sounds FANTASTIC.

While I wish it had a solid top, The Official Vintage Guitar Guide indicates (pg 207) the GCS (Grand Concert Series) 6 has a laminated spruce top with mahogany back and sides.I know for sure that mine has mahogany back and sides, and Martin Company folks indicated the top was (likely) laminated...though the one sited in the OVGG was a 1994 and I bought mine in 75.

From what I've seen, you can ferret out the year your guitars were produced from the serial #...as someone indicated previously. My GCS-6 begins with 74, the year I'd expect it was born, as it was purchased in 75. Several have asked about the value of the GCS model. Sterling indicated the higher the # of the various models, the higher the quality of the instrument at production (ie 1 at low end). Elderly music recently had a really beat 6 with an asking price of $35. I've seen others sold on ebay in the low to mid $200 range. I've also seen where folks were asking considerably more...but you can ask whatever you want. Bottom line to those wondering what their GCS-6 is worth;if you have an early model (72-78)in good shape, ask $250 and maybe come down a little from there.

Wow, what a good place for info on Sigma guitars. Last year I purchased a used SDR-28. The top looks to be solid and I assume the "S" in SDR stands for solid top. I did change out the saddle to a tusq and lowered the action. I'm using light gauge Elixer coated strings on it. What a player. Intonation is closer than what I've heard on guitars costing much more. I've compared it to a couple of Martins, thus I think I've ended my quest for a high end Martin. This guitar has exceptional tone and has aged well. I can't make out the engraving inside as to it's origin. If I was to go home tonight (at work now) and post the serial no. would this possibly provide me with origin and year?

What a great discussion I fell upon. I have a DR-7 that I got new in 1970. It has the zero fret and adjustable bridge and a great booming sound. I have had other guitars come and go but I have never, ever considered letting go of my Sigma(I currently own a couple of Taylors I use for finger picking). This guitar is a war horse and has taken lots of abuse over the years but it remains in great shape.

A few years ago I had new tuners installed. After reading some of the comments here I might consider replacing the bridge saddle and nut with bone. Recently, I decided to get serious about playing slide and easily set up my Sigma for the job. The adjustable bridge made it easy to raise the strings and the zero fret allows for buzz free slide action at the top end of the fret board. I have gotten lots of comments about how great it sounds with slide. I think I will take this guitar to the grave with me.

Thanks

Just thought of letting you all know there is a D10 currently for sale on eBay. It´s for sale on "Buy it now" or "Best offer" deal for another 3 days and 4 hours from this moment. Buy it now price is $1000 with shipping included. Once again being from Finland, Europe, I´m out of the game since the seller states to ship only to USA. And no, I don´t know the seller neither am in any kind of relation or connection to, neither have absolutely no personal interest in who gets to buy the guitar. Unless you want to define "personal interest" that I would be happy to hear someone that really appreciates it also gets it.

And please come back to the forum to share your happiness, disappointment or simply brag with what you´ve gotten to yourself :) And of course to tell how the guitar is ;)


Take care, good luck and happy bidding to you all who decide to give it a try!

   From reading through many of the posts on this very informative site, it would appear the guitar was made between 1980 - 1984? Does the S in "35S" stand for sunburst?
The guitar has been well lived in, but the only flaws appear to be purely cosmetic. Any ideas on its value or the year of make?? I think I'll get it properly set up before I re string it. Cheers Geoffrey

To Bozeman: I too have an early DR-11 in great shape. Mine has the SIGMA with Greek M name on the head as opposed to EST 1970 . The Sigma name is in mother of pearl (I know of only two that have the Sigma name in MOP).
Your guitar was made 1980 or later as that was the year they changed the headstock wording from SIGMA Greek M to the EST 1970, even though they did start making them in 1970. The DR-11 was top of the line when it was made. Almost all of the DR-11 were made in Japan and all of the ones that have the SIGMA with the Greek M on the headstock were made in Japan. The consensus is that the Japanese were better made. I also a pristine D-10 Anniversary model. With good light strings it does stomp Martin D-18 Butt.

About two months ago, I bought a Martin D16RGT (dreadnaught with scalloped braced solid sitka spruce top and solid rosewood back and sides) and a used mint condition Sigma DR 41 (dreadnaught with scalloped braced solid spruce top and laminated rosewood back and sides.)

Both guitars sound much better now than when I bought them. I have changed the saddles and bridgepins to bone and adjusted them for close action, and added Fishman Gold + pickups in each.)

The Martin is more expensive and more prestigious than the Sigma...but which one is better? I really can't say. The Martin is a little sweeter sounding, but doesn't have nearly as much volume and clarity on the treble strings. The fingerboard on the Sigma is a little wavy but it feels fine.

Which do I like to play more? I really can't say, but the question of the advantage of solid back and sides over laminated back and sides has been a puzzling one. It would appear that for the type of bracing these guitars have the rosewood tone is due to reflection rather than vibration.

Cosmetically, I would prefer that the Sigma didn't have all that fake pearl inlay, and perhaps a darker top like the Martin, but I wish the Martin had a glossy beautiful finish like the Sigma.

Now I wonder how many of the solid top Sigma guitars are beautiful like mine. I bought it as a back up guitar and it has far exceeded my expectations. I have three Martin dreadnaughts and on a given day, the Sigma is as nice as any of them.

I bought myself several sigma guitars in the last 12 months, looking for "the" guitar, lowsuite, for me.

i don't want to say that i found it now, cause this would be too early, but the best playing and sounding sigma guitar i have is definatly the DR-35N i purchased some days ago.
this one has a solid top and laminated back and sides, martin tuners and a martin serialnumber.

the sound is great, and it plays really well.

i'm sorry to say, but all other sigmas i have (all laminates, but with old sigma logo (dm-5 12, dm5, 52sdr7 and another one without a modelnumber but a green Martin papaerlabel???...) are nothing compares to the dr-35n.

i don't know, maybe its the solid top, or the made in usa, i dont know, but this guitar really is balanced on all strings and played strummed, it sings and sounds just great...

what do you think of it. does the solid top makes the differance?

keep on playing,

I'm hoping someone can help me get some information about a Sigma SDR-28 I bought my son second-hand a couple of years ago, serial number 89098551. It is in beautiful condition and came with the original hard plush-lined case. He was just starting to play at the time, and since then has gotten lots of compliments from experienced players on the sound and quality. I'd love to have more information about the guitar. (Not that he wants to sell; he's quite happy with it.)

Following internet links, I gather we lucked out. It sounds from the SDR, that it has a solid spruce top, but I am not sure if it has mahogany or rosewood sides and back, and suspect those are laminated. I also suspect it was made in Korea, from other internet chat, but am just guessing. Can anyone guide me to a Sigma serial number site, help me get additional information, and get a sense of what it's worth?

I now have three Martin dreadnaughts that I really like...and a Sigma DR 41. It's really hard to say which is the nicest sounding guitar. I know the old D 18 and the new D16RGT and the new DCX1E are more valuable, but playing them side by side the Sigma holds up well.

I've been involved in discussions about the value of solid woods and the consensus seems to be the top is most important. The back and sides are more important for reflection than vibrations...meaning the Martin road series of solid tops with laminated rosewood backs sound as nice and many of the higher end Standard series.
(However, I've learned from a respected luthier that much older Martin standard guitars had a different bracing on the backs making them vibrate more.)

Anyway, my Sigma which is still in mint condition and has a white looking top...sounds fantastic. I haven't played any others like it so I don't know if it's an anomaly, but I paid $295 for it with a case a few months ago and had a Fishman Gold + pickup and I love playing it. I wish my solid wood Martins were as loud. To be fair, my D16RGT is a little sweeter, but this is one of the nicest guitars I've ever owned.

I did manage to find a Sigma catalog and flyer and for the original owner, they carried the same warranty as the Martins. The repair man at the Martin factory agreed that the sound was remarkable. Others at the factory said they stopped making Sigma when the Mexican plant opened and a solid top Sigma is like getting a Martin for less.

I am pretty stoked actually. As I sit here playing my Anniversary for some reason I decided to look it up. I am so glad I did, but now I wish I would have taken better care of it. Still in fine playing shape and looks pretty good. I inherited it from my Aunt who died when I was 15 so I would never sell it. I am glad to know that it is even more special than sentimental though. What I know about the Anniversary is that there were only 100 made to mark the last from Japan. Spruce top with mahogany back and sides. The binding and pick guard are tortoise shell and the finger board is rosewood with pearl "snowflake" inlays and the word Anniversary on the 20th fret. 2 more snowflake inlays on each side of the bridge. I love this guitar and every time I look to replace it I cant find anything that sounds or plays better for less than 2K. Find one if you can, they are a bargain even today. Stays in tune forever.

To All interested in Sigma DR-11

I have a Sigma DR-11 that I purchased new in 1978 for about $335. It has a solid spruce top, rosewood keyboard, and I believe solid (?)rosewood back and sides. Like others described here, it is a three-piece back, and has mother of pearl inlays around the sound hole and on the neck.

It has gold leaf "Sigma" on the head, AND it says "Est. 1970," which contradicts another post in this thread that use of this didn't start until 1980.

I've wanted a real Martin ever since I bought this guitar, and just today took my DR-11 in to a local music shop here in Bozeman (a signature Martin Dealer), and my DR-11 sounded as good or better than some of the new D-28s I played: Honestly!

Though my older Sigma, which is one of the "Made in Japan for CF Martin" models has a few dings and would probably benefit from a good retooling, it's in pretty good shape and I am amazed at the sound quality. The dealer was quick to offer me $350 on a trade in on the Martin I was looking at, and I decided since my Sigma sounded notably better than the JC16RGTE Premium I was looking at to keep it. Glad I did after doing a bit more research and reading here that apparently (a) many of the 1970's Japanese Sigmas are considered to be pretty good guitars, and (b) the DR-11 may be one of the rarer models.

Perhaps the lesson in all of this is that when I bought this guitar, a friend of mine who DID own several Martins said that the quality of wood--and of course the general quality of the design--was VERY important. At that time, the DR-11 was thought to be very similar to Martin's D-35. Over the years, my spruce top / rosewood sides and back guitar has aged nicely, and if my sound test today--confirmed by two others--is any indication, my original buy was a darn good deal!

I'd love to hear more from others who own a DR-11, or from anyone who knows more about their history and current value.

I bought my Sigma DR-28c new in 1983 for around $650 at a guitar shop in London, Ontario. After a minor adjustment, the action is low, fast, and light. I normally string with extra light coated strings and am really impressed with how well it holds tune. I've had a few professional musicians play my guitar, including Kix Brooks from Brooks and Dunn, and all were very impressed. One player offered me $800 and I believe he was low-balling me (he knows guitars!). Although it's hard to find info on it, I believe it's design is based on the Martin D28.

Hi all!

I just decided to come and spread the word here. As far as I know the rarest and most wanted Sigma model is for sale at eBay for another 15+ hours. We are talking about D-10 model here that I understood was Sigma´s 10th anniversary model and they made only 100 of them IN Nazareth, PA. The highest bid right now is $405.12 and yet the reserve is not met. I would be interested in this guitar myself too but the seller states he doesn´t accept bids from outside the lower 48 US states, so I´m out of this game. What would make me a bit hesitant in offering much more is that purchases from this seller have only $200 buyer´s protecton. But... if some one is interested at least there´s a chance to get in correspondence with the seller should the reserve not be met during this auction. If you´re near Ozark, Missouri, US, you might be able to arrange viewing too, if the guitar doesn´t sell in the auction of course.

Here´s the link to ebay:

PS: I'm in no relationship of any kind with seller. Just thought some one of the readers here could be interested in, since these don't show up very often.

I just bought a used Sigma DR 41 in mint condition with a hard shell case. It was a little tight, but I restrung it, took down the action on the saddle and nut and after playing it for a few days...it sounds wonderful. It's not as bassy as my new DCX1E. It's not as sweet as my 30 year old D 18, but it's somewhere between the two and very responsive.
It's far better than my Alvarez (which has a nice pickup and onboard tuning).

It's very light colored (like my D18 used to be) but if it sees more time out of the case, I bet it will get to be that same honey color.
It was relatively inexpensive for a solid top scalloped braced guitar and is a real pleasure to play.

I'm looking at another used Sigma tomorrow. For a small fraction of the cost of a Martin, the DR 41 has a large fraction of the feel and sound of a Martin. I don't know if they're all that nice, but I like having something I can enjoy playing without worrying about it as much as my higher end guitar...and it sounds good enough for acoustic gigs.

Nice to find some info on Sigma. I bought a DR-28 (C) with a very good case a few years ago for $350 US from a coworker. I was sold by the resonance/volume, even though the action was painful. It has not a scratch nor a ding. I'm no luthier or, for that matter, no real guitarist but I have been sanding the saddle down a bit each time I change strings. The action is getting better and the intonation is still good. Maybe I'll mess with the nut if I don't get satisfaction from the saddle tweaks. I E-mailed Martin my serial number and asked for info on materials, price, date of manufacture, etc. Martin's rep said I "did good" buying this guitar at the price. Also, the rep told me that Martin doesn't have a lot of information on Sigma. She did tell me that my Sigma was made in 1989. She confirmed that it is Sitka spruce and rosewood. Friends of mine have Taylor, Yamaha, Takamine, Simon and Patrick, et al and I believe the sound of my Sigma is in the same ball park if not the same presumed league with any of them. All of you who are happy with your Sigma play on, enjoy it, and save/invest the grand or two you could have spent on a more coveted guitar.

Hi,

I fairly knowledgeable about guitars, or so I thought...

...but someone just offered to sell me a Sigma GCS-1...and I know nothing about Sigmas - except for the fact that they are (were) made by Martin.

Are these "decent" guitars? I'm really just looking for a "beater" to leave out in my family room (i.e., I don't plan on humidifying it or anything).

Thank you,

Comment on Paul M:s SG-5 Hummingbird copy.

After speaking with several people with background in the Levin company, there were some models imported to Europe by Levin, besides Martins Sigma models. Initially they were sold under the brand name Nippon Best. There were Martin style models labeled SM-X and Gibson style models labeled SG-X where the M is for Martin and the G is for Gibson.

In the later years of the 70:s these Guitars were branded Sigma, but the model numbers remained. I have never seen these Sigmas without the "Guaranteed by Levin" marking.

The information I have is that these instruments were all laminate, so I would check that Hummingbird top again.

During these Years the Levin Company handled the complete European distribution of Martin, including Sigma.

My experience is also that the Sigmas of the 70:s with the "Greek-Sigma" marking are all laminate. I have one myself (GCR-7) and I have had correspondence with Ebay sellers, who have checked for me.

I have a Sigma DM-5, circa 1976. When I got it, the action was too high and the sound was a bit muddy. I took it to a guitar shop, had both the bridge and the nut replaced with bone, the frets filed, and the action lowered. After those modifications, the guitar sounded wonderful and played beautifully. And still does in 2008. In my book, the Sigma DM-5, when properly finished, is a Japanese Martin classic. Amazingly, they are still relatively cheap, albeit without modifications. So, if you are lucky enough to find one of these guitars and are willing to put a little money into it, you'll have a friend for life. -JAG

Hi people.I want to add to my previous post from the above date and correct a couple of errors.I recently discovered a build/serial number on the bracing between the soundhole and the bridge of my 52SGCS-6.#493.I also previously stated that I had purchased a DK-28-12 string from New Zealand since I was told thats what it was,in fact it is a DR-12-28.The serial being #S46806.To add to my tale I recently had success on ebay Australia and landed an 52SDM-12-5,as luck would have it,it was only 10kms from where I live and my bid posted with 3 secs left on the clock and I got it.After getting it home and looking it over I found the serial number of #496.This makes me think that both my 52,s were practically built side by side and yeah they are fairly low numbers.They both have the SIGMA symbol inlay and gold lettering on the headstocks.I believe that all 3 guitars have solid tops and suggest this is indicated in the 52 model codes and in the S***** serial of the DR-12-28.I also suggest that L***** serials may indicate laminate on other later models.My collection seems to be growing real fast at the moment as I am also holding 2 Tokai Cats Eyes with another in transit from Japan,as most would know Sig's and Tok's were all made at the same place and I have keen interest in both but am not limited solely by them.My luthier(another recent associate) and definitely someone I rely on at the moment says I have got G.A.S..............Guitar Accumulation Syndrome and you know --He's right.For anyone with guitar problems it's well worth getting to know a luthier or guitar tech.Most minor faults can be cured with a set up and it doesn't cost a fortune.If your guitar is not playable,its useless.Great forum this one and I'll be watching more often than in the past.Somethings got to keep me off ebay!!!!!!!!!!!!!!!!!!!!!!!!

Firstly - Great thread here. I bought a Sigma bass a few years ago. It's a 1973 natural finish through neck ric type bass with mono /stereo outs and single truss rod. The bass plays very smooth. Looks gorgeous. Just wonder how many were made as I can't find any info about it. Can anyone tell me about the serial markings which are only REAI on headstock.

Subject: RE: sigma guitars
From: GUEST,Thomme
Date: 25 May 08 - 12:44 AM

yeah, mine has the zero fret, truss rod adjustment on the headstock and a midseam on that back. It also suffered from some terrible structural issues in the top. The bridge itself actually cracked horizontallyabout 2mm above the soundboard, as well as pulling the top laminate off the board, bellying the board, the top laminate cracking vertically down the front of the guitar and chewing up the bridge plate. About $200 in repairs, but I'm almost happy to pay it to get it fixed (I love the guitar so much). There is almost no consistancy with these older Sigmas and it really frustrates me.

Subject: RE: sigma guitars
From: GUEST
Date: 24 May 08 - 06:20 PM

Just as Thommes DR12-7, my GCR-7 with sideways M is all laminate. I have been lead to beleive that the model coding means GC for "Grand Concert size" and the R is for Rosewood. The 7 is model level, where 7 was one of the highest levels. My sample has a zero fret, but I have seen other GCR-7:s without it, and with sligtly differrent design. Mine does not have any pattern in the midseam of the back, whereas others do.

I have read in Levin brochures from the seventies (Levin Guitars was the Martin and Sigma distributor in Europe in the 70:s)that the Sigmas where bought from several different producers in Japan, which explains why there may be a differrence between instruments with same model code.

From: GUEST,Thomme
Date: 21 May 08 - 04:04 AM

I should pop in an let this be known. I've got a Sigma DR12-7 that's currently in the shop for a bridge that was bellying up and pulling, with it, the top laminate off the guitar. These things definately aren't solid wood. Not a chance in hell. Mine's got the early Gold Sigma logo (with the sideways M) and a seriel number of 8200. This guitar has an awkwardly figured internal grain on the back (it looks flamed) that doesn't match the outside at all. The top is definately a laminate top. I'm a little disapointed in this fact, as for 6 years, I thought differantly. But, I love that guitar, and it's honestly a fantastic sounding guitar, too, especially for an all laminate guitar. People I meet have always been impressed with how nice the guitar sounded, but now my spirits a little broken with it. Now, everyone's more impressed with my Blueridge.

I'm wondering if anyone here can direct me to a good internet resource or help me to identify approximate vintage and Model Number of one of my Sigmas. It's an oldie from Japan, missing the label from inside, so I'm at a loss to identify it.

It has the old Greek Sigma character on the headstock, with "Sigma" spelled out just below. It appears to be cedar top with Rosewood back and sides, with white binding around the body edges and headstock, but the fingerboard is unbound. It has plain generic sealed tuners, (like my old Ventura), and a sunburst finish on the back of then neck, but natural everywhere else.

The rosette and pfurling around the top edges are plain, no abalone, and although everything seems solid as a rock, the strings are a mile high off the fretboard, leading me to wonder how to bring their height down to a more playable level. It has a wonderful Martin-like boomy, percussive tone, and I think its worth the effort, but I sure would appreciate if anyone can help me to identify it as to model and approximate vintage.

Thanks.

hey Rich, i too own a DR28C Japanese made that was given to me as a gift in '82. it is a beautiful florentine single cutaway that as you say was not made in very large quantities. the later Sigma cutaways have a more rounded style and i have seen many of this type whereas, the one i have comes to a nice pointed tip on the cutaway. this guitar was bought brand new with an excellent hard- shell case and was just under 275.00. originally, it was very brassy sounding with a lot of treble but as it has aged over almost 30 years it has mellowed in tone but not in volume. i love using this guitar in open tuning as it rings out with great tone and volume. I have never seen one up for sale anywhere so cannot say what it it actually worth but if i was pressed to sell mine i would take no less than 400.00 for it.

one of the three Sigmas i have is an original low number(5435) DR-7
that was made in japan and has the paper label inside with rubber stamps on the label denoting model,serial number and Made in Japan.
the label itself reads:

    IMPORTED AND INSPECTED BY
    THE CF MARTIN ORGANISATION
    NAZARETH,PENNSYLVANIA USA
Model
DR7   SERIAL NO. 5435 MADE IN JAPAN

It also has the greek symbol SIGMA and gold lettered SIGMA on the headstock.

I read that Martin took the M from their name and turned it sideways to perfectly create the SIGMA brand.
As SIGMA guitars returned from Japan to the USA they came through the Martin factory in Nazareth,PA to regulate action,intonation,finish,machinehead adjustment and saddle adjustment.


i can only guess i have an early 70's model. It plays absolutely beautifuly with some 30 odd years of age to what at the time was very good quality tonewood from Japan. It has crisp clean high notes and very good mid and low end tones with an overall balance that few other acoustic guitars that i have played can match. The action is low and the neck and fretboard are a joy with ease to play. I will admit to being biased as i own three Sigmas and love them all.

All of the Sigma's with the Greek sideways M were made in Japan. They changed to the new headstock logo in 1980, but the guitars were still made in Japan through 1984, at which time they switched to having them made in Korea. Your guitar with that low of a serial number is probably very early 1970's. Serial numbers on Sigma's are confusing, but that is a very low number. According to what they sell for on E-bay, if it is in really good shape, it should be worth
$300 to $500. The early Japanese DR-7's are worth more than later ones and seem to have really good tone.

I'm trying to figure out if it is one of the early 1970's DR-7's or from the early 1980's. Mr. Webb suggest that there was a run of these from 1980-1984, unless I mis-read that part of his post. The paper label does not specifically state that it was made in Japan nor is it stamped anywhere. Any information would be appreciated as well as approx. value.

Unfortunately, in general information on Sigma guitars is quite scarce. Aside from this forum, from which you will glean almost
as much info on these Japanese guitars as there is to be found.
THe only other place i have gotten Sigma information is from Sigma
items on EBAY or from direct promotional material like old magazine
adverts.
As production moved to Korea(1984-93/94) then Taiwan(1993/94-2007) there became no back info especially since production of the
Sigma was ended in 2007.

I have a Sigma twelve string 52SDR serial 25445 made in Japan. Sigma cf Martin and Company on the label. Bought it back in the eighties new. I think it was about $460.00 Canadian. It's been strung tight all these years and the action in as good as the day I got it. A beautiful instument in my opinion.

Hi everyone. There are some GREAT guitars up on EBAY at the moment -

As valkyrie guy said, there is a D-10 up there,as well as:

a few Dr-28H (H = herringbone)
1972 MIJ DR-7 12 string
an SE-19 - thinline acoustic / electric w/ Florentine cutaway
SE-28 - thinline acoustic / electric w/ Florentine cutaway
An SMC-68 - does anyone know ANYTHING about this axe?? I've never heard of it or seen one in an advertisement - I'm quite intrigued...
EJ-35B - semi hollowbody double cutaway - only made for one or two years in the early 90's. I have a ej-75 that is a solid guitar, and I assume the 35 is just as capable. Great tone.

If anyone knows anything about the hollow bodies or specifically about the SMC 68, please enlighten me!

thanks

hello, i have a 80-82 DR-28C MIJ that is a beautiful single cutaway that i have never heard of or seen anywhere. it cost under $300 brand new with a solid case in 1982. when new it was very brassy and very loud and i used it mainly for slide. as the years have passed it has mellowed in tone and sounds great for open D or C as it really rings out with the overtones of open tuning. the soundboard has become a beautiful deep amber color from its almost blonde spruce when new.
i have two other Sigmas, a DR-7 and a GCR-6 both early logo MIJ guitars that i will post about next time.

re:the dr-28n .... it's good to know it survived your travails Jim as this model was actually the only Sigma model that was built in the US at the Nazareth,PA (which gives it the n designation)factory! It's virtually a clone of a Martin D-28,was built in small numbers and should be labeled MartinSigma/USA.

I've had plenty of work done on it to keep it up to snuff over the years but have generally abused it by hauling it all over north america from the mountains and campfires to the ocean life on extended exposure.

To guest nick long, my 52SDR-9 has the same neat cross style fret markers. It is the only Sigma I have seen with it. Mine is a little earlier, has the Greek Sigma symbol on the headstock. These 52S models were a professional series and really well made, with great sound, even if they did have strange laminents on back and side. They were higher end than the DR-7. Enjoy your guitar.

To guest Karen. Yes the DM-1 is the lowest quality, but is still worth every penny you paid and then some. The case could be worth the $75.

Previous owner says he bought it ten to fifteen years ago. Inside label says made in Korea. How did I do? Sounds like I bought the bottom of the barrel (I was excited because I knew Sigma was an off shoot of Martin). I am bummed though because the first string is buzzing really bad - so right off the bat I've got to have it looked at. Give me feedback please, good/bad/ugly all appreciated!

To guest Martin, The highest number DM I have seen is a DM-5, not to say they do not have higher numbers. If it is a DM-8 it ia assuradly rare I would say. Could have been made from early to mid 70's on. Does it have the inverted M headstock or the "est, 1970" headstock?
The M in DM stands for mahogany back and sides, and I have seen some DR models in the higher numbers such as DR-7-9-11-14 & 15 but not the DM models. Of course I certainly have not seen them all, but yours is probably pretty rare. Look in the sound hole at the sticker to see if it was made in Japan. The Japanese are the best of the Sigma's.

If you add up all the Anniversary model owners on these pages, we may well account for at least a third of the 100 made! I also have the Sigma Anniversary Model from 1980 and am the original owner. Back in 1981 I really, really wanted a Martin coz all my favorite musicians played them. As a high school senior, I quickly found that option out of the budgetary question. The salesman told me to try this Sigma. It had been kickin' around the showroom for a while as it was not a "real" Martin like most folks wanted. Soon as I played it I was sold. It has been my primary guitar ever since and it sounds even better as the years have passed. I do a lot of flesh picked fingerstyle and it gives a perfect balance of bright and warm with amazing natural volume. Strummed it fills a space with ease, losing nothing in nuance. I was so glad to stumble upon this forum and find out more about my Sigma. Now more than ever, I feel blessed to own this special guitar!

I just bought a Sigma DR-7 with serial# 6465, located in Amsterdam (Holland). First I thought it was ragged (bad photographs), but when I had it in my hands it was actually in great shape. Headstock has the SIGMA in gold capitals with the sideways M (or greek sigma) in "golden mother of pearl" above it. Inside is a paper label saying:
                                             SIGMA
                               C F MARTIN & COMPANY
                                        MODEL DR-7
                                     SERIAL NO. 6465
                              MANUFACTURED IN JAPAN
Bridge saddle is not adjustible. Topnut, saddle, endpins and strap-pin are very cheap plastic (will change). I am pretty sure that top, sides and back are laminated: looking at the side of the soundhole rim shows the venation (lines in the wood) are only in the top mm of the wood and then another colour wood starts. The lines on the sides and back are not near the same on the inside and outside. Nevertheless a beautiful guitar with great sound, now I know what people mean with a grand piano sound from a guitar. I installed new tuners and a bone saddle, new strings and set it up right, and it really sings, the lower strings vibrate like a baritone in a cathedral. As far as I remember, my father's old Martin D-18 sounded a bit more sofisticated, but this Signa seems to have more power (could also be strings or set-up off course). I payed 170 euros ($250) to a friendly beginner, who thought the sound too soft (??), he knew what it's worth, and had other bidders, for the same price. So this is what you pay for a 70's Sigma in Holland (although I have seen people ask 450 euros ($650) for a post 1984 DM-2, probably still on sale). I am very happy with this beauty, it's just the price/quality combi that's right for me. And I love early 70's gear...

The Japanese Sigma's are the best and some of the Korean are pretty good (DR-28,35,41 and 45) also the DM (Mahogany) withe higher numbers ie. DM-5 is better quality than say a DM-4 and so forth. The Taiwanese or Indoniesian are all of lower quality than the others. They are the later Sigma's and most are DM-1 status which is the lowest quality you can get. If you want to have it as a collector guitar, but the Japanese models. If you want good players, also Japanese but lots of the Korean made sound very good. The older they are (aged) the better they sound.

I'm pretty sure the DM-4 was made in Korea, but some may have been made in Japan just prior to the change. If you can see or have someone read the sticker in the soundhole, it should say. The M in DM stands for Mahogany back and sides. The DR-7 with that serial # would most likley be early 70's and if sound in body, an excellent guitar. I don't know the exchange rate of the euro, but that sounds pretty fair in price. Then again the Mahogany guitars sound rally good, so if it is mint, depending on price???, you may like it really well.

Have not heard from Mr. Webb in a long time, but if you are still reading this thread, I have one of your mystery Sigma's. Sticker is missing from inside. It has the Greek Sigma symbol and the word sigma is inlaid in MOP just like the one you stated you had seen only one of before. I think it is a DR-11 from earlier descriptions on this thread, it looks just like the DR-41 but with silver tuners instead of gold and has a three piece back. It is easy to tell it is all solid wood, top, back and sides. Some finish cracks going with the grain but not into the wood. Sounds fantastic. Also have a
52SDR-9 with the earlier logo and snowflake markers. In minty shape. It aslo sounds great, like an aged D-28. If Mr. Webb is out there, please respond if you can, about the MOP SIGMA on the first guitar.

As an owner of a 52SGCS-6 since 1984,purchased as a used model I am always interested to see comment regarding this lesser discussed model.I absolutely treasure mine and of the 7 playable guitars currently in my collection the sigma I would play more than 90% of playing time.I never realised back in 1984 just how good a guitar I was getting for that $110,it seems to just sound better and better and the action is simply excellent.I recently purchased another Japan built circa 1983 Sigma DK28 12 string with Martin thinline p/u installed from the original owner in New Zealand which I have to collect sometime along with a 1983 Tokai CE320.Playing time will have to be shared with these 2 when I get them home.I always thought that the 6 indicated 6 strings now I have seen 4 and 7 so now am aware that this is likely a reference to model updates.I read that the 4 has no neck trussrod.My 6 definitely does and adjustment is via coverplate on headstock.Headstock has the sigma symbol abalone/paua inlay some refer to as the sideways M with the gold stamp "SIGMA" across the face.ID is by way of paper sticker in body and has no serial numbers.

I recently purchased a Sigma DR-28HC. It appears to be a post 1980 Sigma due to the absense of the 'sigma' greek character on the headstock. It does appear to be an older model though so I'm guessing it was made in the early 1980's. I'm wondering what the 'C' designation refers to in the model 'DR-28HC'. It is not a cutaway model so I have no idea. One other trait of this guitar is its soft-V neck. I've never played a Martin or Sigma with a soft-V neck until I found this one. Please let me know if there is anyone with more information about my guitar. Thank you.

I purchased my 52sdr-9 in late 1974. It cost me close to $300.
The head logo is SigmaGuitars in Martinlike script, with EST.1970 underneath it.   The DR-9 is amost indestinguishable from the martin d-28 of 1974 from the front. It has a three piece back in the same pattern dividing splice as the D-28..just 2 splices.   The D-28 I compared it to had looser grains for wood, and it's tone was not as bright un the upper ends or as deep in the lower tones. This with identical freshly strung strings.

The SigmaGuitars logo does not mean your guitar is from later vintage as mine was purchased in 1974   

Serial #29428, so the owner of the 52sDR-9 with serial # 11209 or something like that has at least a '74 or before.

I have been blessed to aquire another D10 anniversary model after selling my first one 25 years ago. Funny thing is I paid the same price for both. $300.00 at Guitar Center in Santa Ana CA. in 1980 and I found one in Ill. 3 weeks ago in a little used guitar store on the internet (which I love). I would like to acknowledge and show apprecation to STERLING K. WEBB for his willingness to educate the masses on the greatness of the early Sigma line of guitars.
    Most people think that so-called lower end off brand guitars made for high end companies are crap. Well I know that Orvilles made in Japan for non-export and non-export Epiphones not only rival but can surpass Gibson Custom shop guitars. As do the non-export Fenders. I know because I have all of them with my Sigma and a hand made Mockingbird by Bernie Rico, owner/inventer of B.C.Rich guitars. Also a 1959 Gibson Classical once owned by Merle Haggard. I will never sell My Sigma. It's sound is so fantastic that I can't put it into words. I think you all know what I mean. Good luck to all, Tim

Hi everyone

This is the only site that I have ever found any meaningful Sigma information on. In order to start building information about Sigma guitars, I created a wikipedia article, searchable by "sigma guitar" There is nothing listed there as of yet that is not available on this site (with the exception of me mentioning that sigma also made basses, mandolins and and electric guitars of different body types) but I would liek that to change. Any and all !cited! information you can provide would be INCREDIBLY helpful and equally welcome. Please post here if you have any questions.

Additionally, I have included an emailed correspondence I received from an employee of C.F. Martin & Co. regarding my recent inquiry about the Sigma line. Enjoy, and I hope to see a lot of information added to the wiki article! I would specifically like to have photos of the different logos (sideways M versus inlaid mother of pearl headstock logos).

Email from Martin -

Thank you for contacting C.F. Martin & Co., Inc.

The Sigma program was initiated in 1970. They were manufactured in Japan, Korea, and Taiwan. They were imported by Martin to serve the lower priced markets. Each Sigma Instrument is brought into the Martin factory to be inspected and adjusted by Martin personnel before going to the authorized retail store for retail sale. In more, recent years, Martin has introduced what they call the "Second Generation Sigma's" with solid tops and extended warranties. As of September 17, 1984 all solid top Sigma's had the limited lifetime warranty to the original owner. All Sigma Guitars are constructed with laminated (ply) backs and sides. Sigma Banjos and Mandolins are of the same origin. For a short time the Martin Co. Imported Solid Body Electric Guitars under the Sigma name.


The Sigma Guitars were discontinued in 2007.


The Martin Co. does not keep Sigma serial number records; therefore Sigma Guitars and Mandolins cannot be dated. The Martin Serial Number list on our website is for Martin Guitars manufactured in the Nazareth plant.

Nippon Best was a Japan made import brand offered by Levin Guitars in the early to mid 70:s. The steelstrings were available in Gibson style versions with model SG-XX and Martin styled labeled SM-XX.
There were also some nylon low priced versions, the cheapest marked "School".

From what I have heard Nippon Best were all-laminate guitars.

I think they were offered under the Sigma brand in the latter half of the 70:s.

I have a Sigma DM-43 (I think it is a 43 or 4S??? - hard to read) It was my dad's; unfortunately he died right after he got it so it is never played. Can anyone let me know @ this model & price it would go for. It is mahagony, says Sigma Guitars Est. 1970 @ top & it was purchased @ 1997 or 1998. Thanks so much!!! Kat

I bought a Sigma DR-11 new in Cookeville, TN sometime in 1979 when I was in college. It has mother of pearl inlay around the face of the guitar as well as the soundhole, and oblong hexagonal mother of pearl inlays on the fretboard. It also has the three piece back with a decorative inlay on the back that pieces the three pieces together. I too have been told my guitar model didn't exist. I am thankful for the information I have found on this website, and hope to learn more. I believe the name of the music store was Middle Tennessee Music where I bought this guitar. I had just come in on a delivery from Nashville. I was told by the saleman at the store that this guitar was especially made for a Guitar Show in Nashville. Being in college I had to go borrow the money and almost lost the guitar to any buyer before I got back to the store. I believe I paid around $350 with a hardshell case. I still have this guitar today and treasure it. Although I collect them and have over 30 guitars, this is still one of my favorites and is the one I have owned the longest. I will never sell it. I use only light gage strings on it and the neck is still straight as an arrow after over 27 years.

Someone asked about the Sigma Anniversay and if 500 pounds is to much. I don't think so, I have one and it is the best guitar I have ever had. It stands up to every Martins in the world, the sound is amazing and if you're willing to pay 500 pounds for a cheap Martin, you should pay 500 for this one that sands up to a expencive Martin.

I bought a Korean made Sigma DM-12-4 at a pawn shop this week. You don't see many older 12 strings that are playable, but the action on this one is still good. The number inside next to the truss rod adjustment says 83007, and the serial number on the inside sticker says 8301729. I love to play a 12 string, but not many of them last long. You can't beat the warm tone of a seasoned older guitar. I have been fascinated by all of the information in these posts. Any additional info would be appreciated.

Lost in Sigma. I have one of the best sounding guitars I've ever played
but not sure what it is. There is a sticker on the headboard that says Sigma Guitars, Est.1970.
Inside has a sticker that says PICADOR, made in Korea. Inside against the neck has a serial #324007. It has no model number or anything else on it anywhere. It looks identical (almost) to my Martin HD28.
It plays as well with not as much tone.
I've seen a few others in this forum made in Korea, but not with PICADOR mentioned. It is a six string.
Thanks Guys, Great info!

Hi Everyone,
I just purchased a Sigma guitar - Model Number s2000 (original warantee paper states this model, but "2000" is stamped on the inside) next to the serial No which is 1390581. The guitar is stamped with "sigma guitars made in Japan for Martin Co", but the headstock does not have either of the sigma 'logos' described above, it has a pearl design very similar to the one I have seen on a "Collings D42", it also has pearl markings on the neck, around its body, and around the sound hole (not sure if that is the proper term). At first I though it was an Anniversary Sigma made by Martin but the models don't seem to match up (model s2000 VS 10?). Maybe I have a different model than I think?

The dealer said he talked to a Martin Rep and they have no records of Sigma ever making this model - its beleived it was made in the late 70's or very early 80's.

Anyone ever hear of this model? Or have any information? I also have pics I would be willing to send out if someone wants to see them.

It sounds great that is why I bought it!

Thanks in advance for any help.

To guest Gary
Buzzing can be caused by a few different things. As you are just starting to play my suggestion would be to lose the med strings right away and fit light or extra light. Your fingers as well as the bridge will thank you for this and the less thick strings may stop buzzing. I if the action is very low the truss rod may need tweaked.
Best option is to take it to a reputable guitar store for a setup, usually cheap and the tech can advise you.

You guitar was likely made between 1980-84

Hope this helps

I recently aquired a Sigma DR-28. It is a "Made in Japan" model. It appears to be solid wood all around (rosewod sides and back, spruce upper) I have a couple questions for the experts atory on how I aquired it (got it for free)

1. Right after I purchased it I restrung it with Martin Med. strings and now I am getting a Buzzing noise off of the frets when I play. I am new to guitars as this is my first guitar and I am learning on it. What is causing this buzzing noise?

2. Aprox. how old is the guitar?

3. Where can I find a replacement Nut fot the guitar?

Now the quick story. My daughters (3 and 5) are starting to take interest in music one wants to learn Piano, the other drums. So I decided that I wanted to take up a new insterment as well (I play brass and some percusion already) I had a nice CD player I had gotten for free in my car so I put it on Craigs List for trade for a PS 2 or guitar. I ended up getting PS 2 with a few games and some controllers for trade. I played it for a couple days then relisted the PS2 for trade for an acoustic guitar and a guy e-mailed me about this Sigma he had so I went and looked at it and it was in really good shape so we made the trade. My wife and I are short on money so tradeing was the only option I have to get anything. So that is the story

Was it a good trade?   Sorry so long.

I have a SIGMA MARTIN DM-5 Guitar manufactured in Japn in the early 70s, SN 73060971. Customer Service at C.F. Martin tells me it is was probably produced in 1973 as they were only made from 1973 thru 1984, and for some period Sigma Manufacturing did use the date as the first 2 numbers of the serial #. Many of these guitars sat in warehouses or stores for years before being sold and it could have been sold to the original owner in any number of years.

This guitar has solid Mahogany Back, Sides, and Neck, Solid Spruce top, Rosewood fret board, and an adjustable Rosewood or Mahogany bridge. If this guitar looked and sounded any better, you would think it was a Martin D-18 of recent vintage. Very nice guitar, it has a rich sound and great sustain.

It was distributed by Levin of Göteborg and has a short serial number. The inlaid writing on the headstock is "Sigma Guitars established 1970". The information pertaining to Levin and the serial number is on the paper seen through the sound hole. I have just had it refretted and bone nut and bridge fitted, it sounds great.

Sigma Anniversary model went for $450 U.S. recently.
It was from a collector and was in excellent condition.
That's about 225 pounds. So, 500 pounds sounds a bit high.

Recently found my late mothers Sigma SG-5 in my friends basement. Had almost forgotten about it so it was nice to find it again. This is the Hummingbird copy, very beautiful and sounds very good, even though i´ve understood that it was a low-price guitar back in the day. Since its the only thing I kept when my mother past away, it´s very special for me. I don't know much about this guitar, coriuos to know about when it was made (I think in the late 70's), what it might be worth now etc. If anyone has the time and energy to help me find out more about it I would be very greatful!

I have a Sigma, Model GS2GCR-7. Serial # is 21xxx (I can't remember it off the top of my head). It has the gold stamp SIGMA with the M on it. It was purchased new in the fall of 1978 for either $200 or $250. (I remember trading in my classical guitar and getting $50 for it, which I though was pretty good since we had spent only $70 on it four years earlier.) My mother bought it as a combination birthday, Christmas and high school graduation present. It seems like it's still in pretty good shape, save two scratches on the back of it. It's spent summers in the woods and been dropped more than once, but there's no cracks on it. It still has the original paper information inside (very readable, good shape). I think I had the nuts changed at some point - there's nothing descriptive on them.

If Sterling is still around can you tell me what you mean that these GS2 models were made of some pretty strange laminates? I took it to buy a case for it last weekend and the guy turned his nose up at it and tried to get me to buy a Martin for $915 (you know - I'd have a new case with the Martin, yada yada yada.) He basically told me that the Sigma is worthless. That, of course, is up to the person playing - to me (granted, I'm just a weekend plunker), it seems like it plays pretty well. One of my high school chums actually used it for a recording session in NYC. I had it restrung some time ago and it rarely needs retuning. Since I'm having a Guild 12 string F112 literally rebuilt, I don't think I want to spend $1000 on a low end Martin if the Sigma does the job.

If anybody can offer thoughts on the guitar itself as well as value, I'd appreciate it.

I've joined the Sigma Owners Group.

An SDR-28 was for sale from the original owner, who bought it in about 1995 and never learned to play. It sounds very good, nice tones, lots of sustain, and bass is not too boomy. This one really sings when tapped, just like my hammer dulcimer.

Headstock has Sigma Guitars EST. 1970 (underlined) in MOP. Pearlish fret dots. Paper label inside says Sigma - Prepared and Inspected by C.F Martin - Made in Korea. Serial 90041052.

Solid spruce top, rosewood sides and back may be solid. Glue job is neat and interior construction looks fine. Fingerboard is a very dark wood with slight reddish and black tones. Chrome tuners with no markings. Finish looks good, not overly thick.

I'm happy with it.

Have two old sigma guitars, SE-36 C Thin body / rounded back cutaways( not venetian) both had a martin thin line saddle pick-up in them from birth and were made with 3 of each other according to the S#'s.

They both are made in Japan and have the sideway M stamped before the S# and are brown sunburst. We own martins, taylors and these and I have to say I have never played an acoustic thin body rounded back guitar that played so well and was amazingly loud when not plugged in. I have played them for years now and play up to a 12th fret bar chord and they are true.

I bought the first one in 1985 and another two years ago. My son and wife were in a music store and my son saw it and made my wife buy it. 200.00 dollars. I believe the first one was 530.00 with a "martin" like hardshell travel case. (big lunky ones) Got to love those sons don't ya'.

Anyway, don't know anything about either of them and thought I would try and find a little about them. Bought both because of the way they played and knew Martin Co. was stamped on them. These models also had the closed tuners that were Martin also I believe.

Anybody familiar with this model please respond.

Hi,
I have a Sigma 52sgcs-4. It was made in 1973. It is still in excellent condition. The sound has improved over the years. I always thought this was a Great guitar. I have not been able to find much info on the net about this model. I have noticed that this guitar does not have the adjustment rod in the neck, so I have been very careful to control the humidity level that I keep it in. Supposedly the best level is in the low 40%.
My understanding is that Sigma is an off shoot of Martin. Backed up by the fact that Martin puts their name on it too. They are made in Japan (to the best of my knowledge). I'm no expert but this guitar has served me well over the years.
I recently bought another Sigma. A "DM1stce" it came with a very nice "Martin hard case". Got it at "8thstreet.com" for $380.00 American-delivered. This one is an electric acoustic with the cut away body style.
A couple of my buddies have let me do a closed eye comparison to their guitars (one a Martin DCX1e and the other was an Ibanez AEF37E)
both electric acoustics. I could not tell the difference between the
Martin and my Sigma. The Ibanez (and I was really surprised by this)
I could pick out every time simply because the tone was more muffled than the other two.
As I said I am by no means an expert. But for the money Sigma is a good low to middle price range guitar.

Soeren or "danserinden",

I assume You are danish and bought Your Sigmas in Denmark, which might explain why Your instruments are marked "imported and guaranteed by Levin". Levin was after they were bought by Martin, the distributor of Sigmas in Scandinavia, and possibly also in the rest of Europe. At the takeover, Levin had already started their own import of japanese guitars, sold under the brandname "Nippon Best".

They were laminated wood in top and bottom, presumably of fairly good quality, Levin would never have put their logo on them otherwise.

In the 1975 Levin catalog, these guitars were still in the Levin catalogs, but I do beleive these guitars were later sold under the Sigma name, and that You have one of these.

In the 1975 catalog there is a Nippon SG-2, and I am shure I have seen a Sigma SG-9 on internet with the same shape of the headstock, quite differrent from the typical Sigma/Martin shape. The SG-9 i saw, if I remember correctly, was black, with double pickguards and a bit decorated.

I've read many of the post here about serial numbers and manufactoring dates. Mine is a 12 string DR-12-7 SERIAL #24233.
In reading bout the serial numbers the 24 would be the number of guitars that month, the 2 would be febuary, and the 33 would be the year. this guitar wasnt built in 1933. But it may have come from the future:)

Hi,

Im trying to read and find out about my favorite guitar of all times. It is a Sigma DM5 S, numbers on the inside (stamped on the wood) S 35618, 011402. I bought it new sometimes in 1980?

I always thought it was a cheap peace of crap, but had it at home as a practice guitar. Every "good" guitar I bought lost in comparison with my Sigma. So for years i've tried to found a expensive guitar that match my Sigma.

The thing with this guitar is that it just sounds and plays so well. Im a professional player (from Sweden) and have a lot more expensive guitars, including Martins and Takamines. When it comes down to nail the perfect sound in the studio, my Sigma always nails it.

Please could someone give me some information about my guitar. There's is one for sale on Ebay and im consedering bying it.

I just got hold of a DR 14, which I can see only one guest has referred to earlier. It has the three solid rosewood pieces at the back and inside two wooden coverings instead of one in the middle. Top seems to be laminated My theory is that those numberes DR 14 was meant for import to Scandinavia and the markets of Sweden Denmark and Finland, as this instrument also is imported and garanteed by Levin of Gothenburg, Sweden, and in other countries the model was called DR 41. I also have a black SG 9, imported by Levin too, with some kind of saddle pickup in brass, and plug in at the bottom. Both have a fantastic sound. Any information on the SG 9 ?

I wish to thank all of you on this forum, particularly Mr. Webb. I just purchased a DR-35 Japan model for $285 on ebay. The sound on this guitar is amazing. It has the spruce top, SOLID Rosewood sides and 3 piece SOLID Rosewood back. I looked at and played new Taylors, Crafter, Fender, Blueridge, and Seagulls. I really do not believe that anything I tried matched this guitar for sound or feel. This guitar has its share of "character marks", but sound and playability are all that matter to me. I don't believe I have EVER heard a guitar sound this rich!!! Thanks again to all of you. Without your convincing testimonies, I probably would not have bought a Sigma.

Hi all!

It's nice to get some information on the old Sigmas. I own a Sigma model DR-7S,... with serial nummer 23214. She's been with me through many of the midnight bonfires and those quiet evenings (21 years). I've written a few songs on it and like an old wine she gets better with age. My best song (in my estimation) is a classical piece written in Em in which my lovely wife walked down the isle to.

I was in a classic rock band in the late 90's in which I was the Drummer (my first love), but we would and still do, get together for the midnight bonfires. One of my guitar players loved the sound of my Sigma so much he went out and bought himself a Martin D-21. Although delighted with his investment he still admires my Sigma.

To all those that believe Sigma is a cheap rip off of the famed Martin; when you find a guitar that suits you, just play it and enjoy. Brandnames don't make music, people do.

I just realized that I never completed a thought from my original post.even though this model was supposedly only produced from 79-81, my dad was born in 1959 and bought it age 15 or 16. That would put the date of purchase in 1974-75. Obviously that doesn't match up, and beyond that, most guitars sit in a store or warehouse for a while before they're sold. (There's a Takamine I've had my eye on for years that has never left the guitar center in the kendal region of Mimai.)

I have a Sigma model 52SDR-7 that was bought new by my father and given to me. According to the brief history early on in this thread, these models were made in small numbers from 79-81, and were made entirely out of "strange" laminates. I'm somewhat confused however. As far as I can tell, the guitar is made out of all solid woods. It has the first generation logo on the headstock and a paper label. The serial number is only five digits (127070, all of the numbers I've seen posted here (I confess I didn't read them all) were six. Anyone know what the story might be here? The guitar sounds great and is still in near perfect condition after 30 years of 12 gauge string tension. The only evidence of wear is a slightly worn fretboard and a slight bulging of the top behind the bridge (which I'm having looked at tomorrow). In the last few months (most likely from my recent move from humid Miami to arid Blacksburg, VA) some string buzz has developed when fretting high on the neck. I bought a humidifier, this guitar is too good to take chances.

Does anyone know whether a Tele guard will fit this (a guard with the humbucker hole in the neck, of course). Another question: By the time I'm done with this, it'll have a new pickguard and a new pot or two, plus non-original volume and tone knobs (although they match the originals). How much will this affect the value? Or are these interchangeable without hurting value?

c.fordson, you asked about the Blueridge guitars. I bought a BR160 about a year ago. The inlay, banjo sized headstock and "aged" (call it yellow) coloration on the guitars top are a bit much, in my opinion. But man is this guitar a cannon. Solid rosewood body and solid spruce top (that doesn't match up all that well) make it a real deal at about $500. Google the model you want and you'll find a better deal than the site you have posted. I got mine from a shop in Kentucky. Though I am very leary about online guitar purchases, the salesperson said I could send it back if I didn't like it (a thing I have done with other guitar purchases), but he insisted I'd keep it. He was right.

As a side note, I was offered about the same amount of money that I paid for the BR160 for my gcs-6 discussed on this site, and there is simply no comparison between the guitars. I have 4 guitars laying around my house (washburn and gibson) and I ALWAYS go find the Blueridge...though I will still never part with the gcs, as that's the guitar I grew up with. I expect that in 35 years folks will be discussing their BR's in much the same manner they speak of Sigmas here.

Jerry   they are usually solid , but I also have an all laminate DR-7. Not to worry   the sound is not audibily different to 99 out of 100 ears. Arguably laminates wll stay sraighter/longer than solid woods, given the solids are more prone to warpage.

I would not trade mine for a solid at this time, (It's also one of the first gen sigmas)   Yours is a valuable instument enjoy it and rest assured laminate or solid you own a very fine music maker

You probably get tired of all the e-mails requesting your expertise but it is obvious to me you may be the only one in the USA with such knowledge. I have a seen your comments on the DR-7 as being one of the most desireable Sigmas. I bought a Sigma DR-8 second handed around 1982-83. It has the paper sticker made in Japan in the sound hold. The serial is 34912. The headstock has the Sigma Guitars est 1970 in script and the headstock is bound in white iveroid. The tuners are chromb and are enclosed. It has the usual nicks, for the age but is still a beautiful guitar and is a pure cannon. I have three taylors, a Larivee and have played with a lots of Martins and this Sigma is no slouch. Please sir, if you know anything about this paticular model please let me know.

This is the ONLY page on Google to come up from my search for Sigma 52SRD-9. I have had serial number 18239 since 1978 when I bought it from a high school buddy (I think he bought it new, or maybe used.)

In the 80's had passive pickups put it (Martin brand) and played it to lead music for youth groups on and off. Now, 26 years or so later, I upgraded the pickups. I think its sound compares to ANYTHING I have heard amped.

This model has the sideways "M" or "sigma" in pearl above the gold block letters as have been described earlier. This is a solid top for sure, and I am about 90% sure the three-piece back is also sold (I can see the grain through the sound hole that I believe matches that of the back (rosewood).

This is a flat-picker, finger-picker's dream guitar!

Oh, not for sale. Just thought I'd see if anyone knew actual year info--I KNOW it is over 29 years old, since I have had it that long.

I have a DR-11 I bought in Chicago in 1982 or so I seem to remember paying a litle less than $400.00.   130354 K under the number.   It had s been through the mill, sort of worn in the sound hole from using a pick up but it's all original and I play it all the time. It sounds sweet an looks like a much more expensive guitar (that's been not too gently used.)

I would have sworn it was 1 piece but I look REAL close and found the seam down the center of the top-this after 28 year of playing it. I love it and wouldn't part with it.

You guys with the DR-11's, when I asked about the solid spruce top, I was refering to laminate vs. solid not single piece vs. a splice down the center. Mine is laminate top but it sure sounds good. Just wondering of some were solid top.

Sigmas can be all over the place in quality and sound. The ones to look for have the inlaid name plate and made in japan. I have had two now, the D18 clone was absolutely wonderful and I deeply regret ever having sold it. I now have a DR28 which is something of a D28 clone, laminated back and sides, V neck. Its OK but not a patch on the old 18 model, or for that matter my martins.

I also had a korean one - yuck. Heavy, laminated top, and a transfer logo. Flicked it immediately it was rubbish.

Looks like go for the older you can, and make sure you test it. the good ones are 90% of a martin, for pocket money prices.

Like others, this is about the only thread I have seen dealing with Sigma's. I recently was given a Sigma SDR-28, made in Korea. I would like to find out more about it. the only information I have found suggests that it was made sometime between 1987-1991. There is a "C" stamped on the back brace. Someone suggested in this thread that it might stand for cutaway, but mine is not a cutaway. It appears to have a solid top. If it isn't, someone did a fine job of matching the pieces. I has the Sigma Guitars inlayed with mop and a gold colored est 1970 underneith it. I haven't seen anything in this thread that mentions the "S" before the DR-28. Any information would be appreciated.

Wow! I've been trying to find some info on my Sigma guitar for a year or so and, as has been said by others, I've learned more in this thread than anywhere else. It's a DT-3 model probably from the mid-80s and I'm pretty sure it's a laminate but it sounds great to me. It's acoustic/electric and I play it through an old Fender Musicmaster bass amp. The tubes really give it a warm sound. It really doesn't quite stand up against my friend's all solidwood Blueridge BR-160 though. The best thing about mine is the appearance. The top (layer anyway) is kind of an orange colored sunburst in flamed maple. Also has a matching flamed maple headstock with gold colored Grover tuners (not original) The bridge pins are brass and have tops that match the flamed maple of the soundboard and headstock (even showing a "grain"). Beautiful guitar. Probably not worth much money-wise but that has no meaning to me since it was given to me by my friend for my 40th b-day.

Medic,

Unfortunately I have to disagree with you about the fairness of value pricing on ebay these days, ebay is not what it once was and a lot of folks have discontinued using it for more than reasons of just price.

Ebay has become a bargain hunters forum where value means little and the lowest price means everything. In the case of the Sigma DR-11, it is likely so rare that there may not be much demand for it at all because it is virtually unknown.

I had an idea one time about starting a website called "ConsignmentMusic.com" and even researched the name only to find that someone in Mississippi had the name reserved already. It was a simple idea where sellers could pay a small fee to post photos of their items and then deal directly with potential buyers via email. This concept has been extremely successful in the audiophile quality audio and video arena. I do not know why no one has done it for musicians yet.

I still cannot establish a reasonable value for the guitar yet, but I am working on it. When I do, I will let you know first.

DaveB,

My Sigma DR-11 has a two piece spruce top with a seam so fine you can barely see it. The giveaway is the change in hue and grain right next to the seam. It does not seem to impact the sound enough to tell that it is not a single piece of spruce.

The "K" on your neck next to the serial number is not likely for Korea, mine has a "K" as well and during that era the Sigma guitars were being made solely in Japan. Later they were moved to Taiwan and the quality suffered, but I have never heard of any made in Korea.

By the way, I did get in touch with Adam St. James, but he could not relate any information about his Sigma DR-11 other than when and where and how much he purchased it for. He suggested vintage guitar dealers and a website called Gbase.com. I looked for one on Gbase and returned a big fat nothing, so the guitar is as rare as we believe it is.

Adam St. James has a cool new website where he reviews musicians new releases and sells some very good books about guitars, vocals, recording, lead styles, etc. It is simply AdamStJames.com.

Thanks for asking about my DR-11,

Hey georbro, is your Sigma solid or laminate top? When I got mine I thought it was a solid top but after having it outside in sunlight one day I figured out that it is a laminate top. (Mild bummer for value but I still love the sound) I'm guessing mine may be from right around the transition time from Japan to Korea as it's stamped made in Japan but the number on the neck block has a K in front of it. Of course, that may be coincidence? I just bought some Martin acoustic SP 80/20 bronze strings for it today but have not put them on yet.

I own a Sigma DR-11 that is appointed exactly as described in Dave B.'s post of July 15th, 2006; J. Kaufman's post dated June 16th, 2005 and Sterling Webb's post of November 3rd, 2004 where he states that he had heard the DR-11 was the rarest Sigma model.

Adam St. James, who is or was the editor of Guitar.com, owns a Sigma DR-11 as well. In a product review for the Fishman Aura that Adam wrote for Guitar.com, he describes the Sigma DR-11 as a "beautifully appointed, lower-priced version" of Martin's D-45. Mine looks exactly like a D-45 with the exception of the 3 piece rosewood back and bracing. If anyone knows how to contact Adam, he may be able to shed some light on the value and rarity of this guitar. My emails to him have kicked back as undeliverable.

This thread is the only place I have ever found in the twenty five years I have owned my DR-11 where it has ever been mentioned. I have had numerous Martin dealers tell me that the model number never existed.

I am very interested in establishing a value range for the DR-11 in mint condition with an original hardshell factory case.

Does anyone have any idea other than the original cost in 1980 of around $400?

Please advise,

I wouldn't expect a Sigma to be better than a Taylor but I'd be interested to hear from anyone who thinks I'm wrong.

Great info here!

I just bought a Sigma DR-11 exactly as described in an above post by J. Kaufman on June 16, 05. Same 3 piece back and lots of mother of pearl around the sound hole, the body binding and down the neck. I am a total novice and got the guitar at a pawn shop with a new hard case (that they threw in) which also contained an electric tuner, a sling, a Dean something wooden microphone pickup thingy that goes across the sound hole and a couple of picks. I am teaching myself to play and my daughter and wife are both learning too. Got the works for $179.00 so I expect I did all right eh?

I'm interested in learning more about the DR-11 and it's rarity/production numbers.

Also, several mentions have been made about installing bone nuts, and ebony pins. Where would I look to find these? I'm handy as heck with making about anything and I was wondering about making a nut from something like a piece of deer antler. It would be a piece of cake for me I think, I just don't know about the sound qualities but bone is bone more or less....aint it?

When I was a child, my grandfather bought me a Sigma Martin Classical Guitar made of Rosewood and with ornately carved tuning pegs that looked like mother of pearl. It had to have been one of the first models, as my grandfather died in 1970.

In a misguided effort to simplify my life about ten years ago, I gave it away to a friend's son, but now that my own son is studying guitar, I wish I had it again. Is there any way for me to identify what model it was, find a similar vintage model, and figure out how much to spend???

Aside from the Picador medallion (covering badly damaged gold lettering (SIGMA) and the pearloid Greek letter sigma on the headstock there are no other marks at all!

Description:
Double cutaway;
2-single coil pickups;

2-black tophat knobs (1 volume the other tone) one located on the left side of the f hole the other on the right;
Garish red and yellow pick guard that is screwed directly to the body;
2 white on/off switches on the pick guard;
Body is dark brown, solid front and back and seems to be laminate;
Body is bound top, bottom and neck with what appears to be ivory but is probably plastic;
Three on a side tuners, chromed metal;
Neck seems to be bolt-on;
m.o.p. dot inlays on fingerboard (can't tell what kind of wood)

The only other information I can provide is that I purchased it at auction in Wilmington, N.C. sometime between 1994-1996. That close to Camp LeJeune I'm pretty sure it is Japanese or Korean. I don't really care how much it's worth. I'd just like to know what year, make and model. Please Help!

Other info about Sigma Electrics

Japanese Martins
Martin's first era of flirtation with electrics ended with its GTs, and, in terms of American production, wouldn't resume until a decade later. However, in 1970 Martin joined the growing list of American manufacturers to begin importing guitars made in Japan, introducing its Sigma series. In around 1973, Martin, like competitors Guild and Gibson, began importing a line of Sigma solidbody electrics made in Japan by Tokai.

Like virtually all Japanese-made guitars from that era, Martin Sigma solidbodies were basically copies of other American models. Martin Sigmas employed slightly different headstock designs, unlike many copies carrying Japanese brand names, but essentially these are similar to most other of these early copies.

In 1974 Martin Sigma electrics included two SGs, a Tele and a Fender bass. The SBG2-6 was pretty much a straightforward SG copy with a bolt-on neck, center-peaked three-and-three head, block inlays, large pickguard, twin humbuckers, finetune bridge, and stop tailpiece, in cherry. The SBG2-9 was pretty cool, with a natural-finished plywood body, white pickguard, rosewood fingerboard with white block inlays, gold hardware and Bigsby. The SBF2-6 was a Tele with rosewood fingerboard, three-and-three head, block inlays, neck humbucker and bridge single-coil. The SBB2-8 was the bass, with natural finished body, three-and-three head, rosewood 'board, block inlays, white 'guard, and two humbucking pickups.

Martin's Sigma electrics fared hardly better than its own electric guitar designs of the '60s. After little more than a year, the electrics were dropped from the Sigma line. The Japanese companies' own replicas, of course, did swimmingly well.

Hello Folks,

      This is a copy of a previous post. I still haven't heard from anyone so I'll try it again.

   
      I have a Sigma SEJ35B, serial # 92000016 that is absolutely mint !! This a hollow-body jazz-blues type electric guitar with F-holes very similar to the Gibson 335. I have tried "desperately" to get information on this sigma model but the Sigma dealers throughout the States and Canada seam to know very little about it. I have even called the Martin factory. From what I can gather from Martin, it has a very limited production of about 6 months in 1993, never to be produced again, sold for over $1,000 US and it is considered to be a very high-end guitar. Any information about this Sigma model would be GREATLY appreciated. You can email me at [e-mail] or respond to this site. Thanks.

The paper label on the inside has been long gone, but it is a sweet playing, beautiful sounding instrument. It has a deep body and long neck, but I have no idea what the model is or what it is worth. Can anyone tell me anything about this guitar?? To me it is a wonderful instrument and well worth hanging on to.

I have two sigmas that i will be selling Early DR-7 with the sideways E and a 2DR-35 that appears to be made from two different woods the 7 is stock and has a high action as the neck sees to be pulling slightly from the body but would be fixable and the 35 is close to pristine and has a brand new fishman in it by a very well established Martin luthier in Portland. I will check back here to see if there is interest and get some pictures ready by the end of March 06.We now are playing Martins (D-42 and D-28 Marquis) that replaced the pair of 35s we were playing.Sold one already.

In response to the above posting by Steve Hankins, 05 Feb 04:

I have a DR-7 exactly like yours; bought it "used" in 1988 for $160 after having had to sell my Martin D-28 four years earlier, (which was kind of a "lemon" anyway). Mine also has the stamped brace (Made in Japan for C.F. Martin Co.), and the inner paper label where the serial number 037980 appears, along with the inscription, "Inspected by K. Saigo." It appears to have a solid spruce top, laminated back and sides, closed tuners that display the word "Sigma", lots of white binding, (including up the neck), and the gold "Sigma Guitars Est 1970" headstock logo. (It is interesting to note that the early Takamines from this period sported the exact logo).

This has always been a great sounding guitar; I took it to the local Guitar Center a couple years ago, and played it in the "humid room" along with the Martins. While of course it could not stand up to the higher end models, it held it's own quite nicely against the D-28 in terms of sound quality.

After finding this web, I ordered ebony bridge pins and a bone saddle from the Martin 1833 shop; the sound quality is much improved! (A nice $40 investment).

Regarding the serial numberings: your's is 024680, mine is 037980. I surmise our guitars were manufactured in 1980; your's is the 24th guitar of the month of June, mine is the 37th of the month of September. (I would like to hear Mr. Webb's view).

While I have my eye on one of the higher end Maritns, (HD-28V), this Sigma is definitely a "keeper".

Hello Folks,

      I have a Sigma SEJ35B, serial # 92000016 that is absolutely mint !! This a hollow-body jazz-blues type electric guitar with F-holes very similar to the Gibson 335. I have tried "desperately" to get information on this sigma model but the Sigma dealers throughout the States and Canada seam to know very little about it. I have even called the Martin factory. From what I can gather from Martin, it has a very limited production of about 6 months in 1993, never to be produced again, sold for over $1,000 US at the time and it is considered to be a very high-end guitar. Any information about this Sigma model would be GREATLY appreciated. You can email me at [e-mail] or respond to this site. Thanks.

I have a DR-7 that I fished out of the closet. I learned chords on it in 1972, when my dad bought it for me when I was in high school. Does anyone have the specs for that model or can tell me where to get them? It appears to be Rosewood B&S and Spruce top. It is beat up but in solid shape (some finish checks on top and plenty of dings). The nut is cracked and can be replaced and the frets need dressing and or replacement. I am considering removing the bridge plate with the adjustable angle bridge holder, with a standard Marting style bridge. The tuners need to have several mounting holes filled and tapped as they are stripped. I may replace with better tuners. Any opinions on whether the investment to fix it up would be worth it?

I've posted on this site a couple of times in hopes of learning more about my old GCS6. I came away believing that my old axe is made of sapele, would have a solid spruce top, and was likely built in 1974 The quality of these original Japanese-made guitars were rated on a 1-7 scale, with 7 indicating the highest grade. On a recent net-world wandering, I've come across two GCS6 guitars currently being sold. Both refer to my old guitar as a dreadnought made of mahogany and having a laminated spruce top. I'm assuming the shops that are selling these guitars have not had the benefit of some of the knowledgeable people who have posted here.

There are several reasons I'm going to trust the information gleaned from this site. First, I have three acoustic guitars; a rosewood, a mahogany and whatever the GCS6 is. The sigma's wood does not look like either of the others. Second, if dreadnought refers to size, the Sigma is not a dreadnought. When I pick it up after playing my BR-160 (a dreadnought), it feels like a ukulele. I can't figure out the top, but I interpreted SW's post as saying that anything done in the 70's would have been a solid wood…back and top. Hmmm. By the way, for others who have wondered about the value of this guitar, nobody has bid with less than a day remaining and with a minimum bid of $300.

A proud new owner adding his good fortune to this sight - Thanks to Sterling Webb for the education I received in researching my purchase. There are a couple of questions for Sterling Webb or any other informed poster to please respond.

1980 Sigma Anniversery Edition Acoustic guitar. Perhaps I overpaid a little at $450 but it made for a content buyer and seller. I purchased from the original owner and workmate, who bought this new for his wife as a gift, and complained because she's only played it about twenty times before finding it's way back into the hardshell case permanently. A few light pickstroke marks across the pickgaurd and perhaps a few about an inch onto the spruce-top finish indicating it those plays. A couple of light scratches only visible on a reflecting light. I would classify the guitar as mint, or near mint. A beautiful guitar and a great sound that carries.

The case was a hard-shell purchased new, but appears to have no brand name associated with the case and no key to lock it.

Identifying marks: Sigma 1980 model Anniversery Edition Made in Japan (stamped Sigma Guitars C.F. Martin & Co, surrounding Made in Japan for…). The number 109 stamped just to the right of this. The 9 was stamped separately than the other, appearing black where the 10 (for model 10) and all other stamping is red-ish brown. Also No S17343 stamped on the same inside cross-brace closer to the fretboard. There is an illegible stamping just to the left of the S (preceding the serial number (could be an N,w/raised o indicating (Serial No), or possibly a capital N, or something else entirely, but I cannot make it out.

There is the numbers 016055 on the inside mahogany woodblock where the fretboard meets the body, with another symbol underneath that looks like the letter K, w/upper & lower V's filled in. 20 frets, solid spruce top, mahogony sides and back (split down the middle/two sections), rosewood fingerboard and bridge with mother of pearl inlays (pointed crosses, alternating square and elongated down the fretboard) w/Mother-of-Pearl Anniversary on twentieth fret, also inlayed crosses on each side of the bridge, with mother-of-pearl inlay also on the end of the string pins. Pickgaurd and binding are tortoise shell and assuming a gloss nitro finish. Tuners are enclosed Sigma. With Mother-of-Pearl SigmaGuitars EST.1970. on the Headstock.

Assuming back and sides are solid Mahogany – definitely the back and sides are Mahogany, just not experienced enough to verify solid versus laminate. I could not get the strap-button off for inspection and the grain inspection matching inside versus out is going to take a another try. The spruce top shows grain wrapping around soundhole – so the top is not laminate. Does anyone know if this is even a concern on the Anniversery Edition?

I read one review that described the Anniversary edition as the marking the end of the solid body tonewoods for Sigma. Are they all solid tonewoods?

Can anyone tell me what the 9 means?

Also will pass along that the dealer told the buyer that this guitar was shipped to the U.S. for assembly. Since I could not clearly make out an N (Nazareth) anywhere I have no way to really know if the dealer was correct.

Sterling Webb - I just discovered you after hours of searching on the web for info on old Sigmas. I am going to be looking at a 52SCS-4 Sigma tomorrow. From what you've already posted, it sounds like this is part of the 52S series made 1979-81 in Japan, "entirely from some very strange laminates". Can you clarify? Should I assume the "CS" stands for a classical guitar made of sapele wood? From what you've written it sounds like it should be a good deal - the seller is asking $125. Any help you or anyone out there can offer would be greatly appreciated!

What an enjoyable evening I have had reading the erudite and knowledgeable posts on this thread. I have been playing guitar for some 27 years the past 22 on my faithful old Fender F3 acoustic bought for £79 in the early 80s. Always a bit of a dog to play, but got much better with age; it did make it onto a couple of major label albums in the late 80s as well! This year I decided I needed something decent for home recording so I budgeted £300 and started looking for a replacement. I had no idea what to get but being more of an "ears" rather than "eyes" buyer – if you get my drift – I blind tested a number of new guitars but never found anything I liked; and that included £1000 Martins. Then a friend of mine brought a 1980s Sigma around and I fell in love with its tone and playability. I decided that I might as well see if I could get a second hand Sigma to try out and a quick net search found an advert for a "1980s DM5" in a nearby city. I sacrificed a day and took the train to Nottingham (yes where the sheriff lives) on a speculation. What I was confronted with was a completely different guitar from the one I expected. At first it seemed "uglier" and older than my friend's but from the moment I picked it up I knew it was the guitar for me. A tone as sweet as a virgin's kiss, and a feel like sugared almonds…..I'm getting carried away here! Well, £220 exchanged hands and she's mine. I now know that she is probably a 1979 dreadnought made from pine and mahogany of the 5th best quality! She has a gold Sigma logo on the headstock with the sigma "M" sign in mother of pearl above and has hardly a scratch anywhere. I have no interest in what she is worth as value is a slippery concept and beneath a true gentleman; however, I would be interested in any information on her making and age. Her back is in one piece and - as with her face - one solid piece of wood. A label inside reads: (M) SIGMA CF Martin and Company, Model DM-5, Serial No. 73103540, Made in Japan. Many years of pleasure await, I have not been able to keep my hands off her since we became one! Indeed she brings the poet out in me as every artiste needs a muse!
Yours prosaically
Alex Peach.

Great site for all Sigma nuts! Hope we hear from Sterling Webb sometime soon. I have a Sigma with a combination of wood, coloring and markings unlike any guitar I have seen before or after. I still think that it is the best looking acoustic (any brand!) I have ever seen. It has quilted maple sides, back and headstock bound in tortoise shell with a thin white stripe. The neck is 20 frets with tortoise shell binding. It has snowflake pearl fret markings and a pearl rectangle with the name SIGMA in the 20th fret. The front binding also has herringbone as does the soundhole and down the back. The tuning keys are gold and enclosed with the Sigma stamp.

The logo on the headstock is "Sigma Guitars, Est. 1970". I bought this guitar around 1980 and the inside bracing has the Sigma Guitars Made in Japan for C.F. Martin stamp. The mystery is the model number. The stamp in the bracing is only partially readable. It looks like D-11 or D-21. I have never heard of a D-21 so I'm guessing D-11 but the first number is hard to make out. I have read Sterlings postings about DR and DM for Rosewood and Mahogany, but what about maple? Anyone heard of or seen a Sigma model fitting this description? I would love to know more about it. Is there any way to tell how many of this type were made and/or its value? Hope to hear more from Mr. Webb on this site. I wish Martin had as much history for us as he does.

Got my GCR-7 Serial # 73010988 "a rosewood 000-21 clone" for $75 from a friend back in 1988. The paper lable is still very readable, and the "M" above SIGMA on the headstock is pearl. There's a black plastic white edged truss rod access cover above the nut. Although not real loud, it's a wonderful sounding guitar with a very comfortable shape. It's been my beater for all these years, but differs from some 000 Martin attributes. Some exceptions are the adjustable saddle, and a 14 frets clear, modified-V neck profile with a 1 11/16" nut (like an OM-21V?).

Based on the GCS-6 post above, I wonder if the first two digits of the serial number could be the year it was made? Thanks for the information, it's cool to finally find some good Sigma info, especially to learn it's one of the "most desirable vintage Sigmas".

    I've been sick for months, but I am now back in tune. I see there are a few "SIGMA NUT" questions for me that have been waiting for answers! I'm going to start answering them in chronological order, a bunch at a time. Soonner or later, I will get to yours!


    GUEST,41815nilsson asks "SIGMA SG-5 marked CF Martin inside and imported to Sweden by LEVIN." This would have been after Martin bought Levin (and then ruined them). All old logo style Sigma's were made in Japan, and almost all are good guitars. Is this a classical guitar?


    GUEST,1980 asks about a "sigma dreadnought in 1980 an anniversary model." These were made for the 10th Anniversary of Sigma, limited run (100-150), SOLID Mahaogany, SOLID spruce, very high quality -- they appear to me (at least mine does) to have been handmade. If it has no problems and is clean, it's worth $400 minimum. Give it a bone nut and saddle and ebony pins and it with go up against any D-18 around.


    GUEST, Bryant asks: "DT-4N 1995 and I was curious as to whether you knew what wood the "T" stands for. Although I'd like to think the "N" means it was assembled in Nazareth, both the stamp and the paper label read "Made in Korea." The T means a maple body, don't know if solid. If made in 1995, it was one of the last Korean Sigmas, as they switched to Taiwan starting in 93-94. "4" is the highest quality number for maple Sigma's I've seen. The "N" is probably designated a finish, like "S" stands for sunburst.


    GUEST,stevehankins asks about, "Sigma DR-7 stamped brace (made in Japan for C.F. Martin Co.), but sports an inner paper label where the serial number, 024680, appears, along with the inscription, "Inspected by K. Saigo." closed tuners that display the word "Sigma", no veloutte (sp), lots of binding everywhere, and the gold "Sigma Guitars Est 1970" headstock logo."

    This would have made 1980-84. To have both stamp and paper label suggests it was right at the 1980 switchover. I've only see n on one other Sigma. I've never seen a DR-7 (which were the top of the line at that point) with SEALED Sigma-marked tuners, so that's unsual, as is the signature. I suspect you got a real good one here. Most (but not all) post-1980 bodies were laminates, the same laminates Martin imported to build Shennandoahs out of, Not too shabby! I've have two post-1980 DR-7's myself and have sold off half a dozen others, 6 & 12's. To be sure about the body wood, look at the grain runs of the back INSIDE, with a flashlight, then compare it with the grain runs on the OUTSIDE back, several times, several places, sides too. If they match, it's solid; if not, not. I've seen only one Sigma from this period that had solid sides with a laminate back, so...


    GUEST,fredvstar650 asks, "sigma dr41 serial number 922055 model number s19752. made in japan. headstock logo SigmaGuitars / EST. 1970" This would be made 1980 to 1984. The S-number means one particular maker that worked for Martin, but I don't know who they were, only the "S" company! DR-41 is the model. ALL Japan made DR-41's were great guitars, solid woods as far as I know. Does it have solid woods? Another really nice one! If it has no problems and is clean, it's worth $500 minimum.


    I know you guys are probably not asking about values and prices, but I throw that in once in a while. The good Sigmas open go for a little more than the cheap Sigma's because they are so greatly undervalued. Hang on to them, enjoy them, and someday the market will figure it out and their values will rise!


    More questions answered next time. Stay tuned.

I'm happy to report that the new Sigmas are every bit as good as the older versions. I just purchased a new DR41 (made in Indonesia). Martin ships the parts over, they are assembled, then the guitars are shipped back to Martin for inspection before selling them. I have several other guitars, including a Guild D46 that I love, but I have to honestly say the DR41 is comparable in a lot of ways. I have played many Martins and this Sigma stands up with any of them. I am glad to hear how solid the older guitars are - I expect this one to last a long time.

Hi! I just bought a second hand Sigma DR-41. It is a Japan model and the one who sold it to me, said that it was made in the seventies or eighties. The serial number is 2781. Can someone give me some information about this model? What kind of wood is used - age of guitar - and so on... I would be thankfull! I bought mine in Norway (where I live!)..

First, let me say I've learned more from about my Sigma from this thread than from any other internet source. Special thanks to S. Webb for sharing his knowlege.
Now, to add to his knowlege...
I have a Sigma DR-11 that I bought in August 1979 (I still have the receipt) for $388.00. It has the newer "est 1970" logo on the head, but inside it has stamped directly on one of the braces "made in Japan for CF Martin & co" and next to it..."DR-11". It has a solid top and apparently laminated back and sides. It also has the abalone inlay around the front binding and around the sound hole and abalone fret markers The curious thing (to me) is that the back appears to 3 pieces. Instead of 1 purfling stripe down the middle, there are 2...eminating from the neck and ending at the bottom about 10" apart. You can see the braces inside following the same lines. I don't know if this is common, but my guitar is the only one I've seen like this.
It's been my only guitar since Aug, 79 (I traded my Madeira A-12 in for it) and It still plays beautifully. I still get compliments on it's looks and sound. I had it professionally set up and re-fretted and a bone nut and saddle installed in 1987 and it's been perfect ever since. [e-mail]

I bought my Sigma in 1990. It's a DR-2 and made in Korea. I new nothing about guitars when I bought it, I got it because I could afford it (AU$299). Now all these years later I have been trying to find out info on it without success. I take it from Sterling Webbs great posts that it is a Dreadnaught Rosewood of lower quality (hence the '2') However, I was at my brothers house last night, and he wants to learn guitar. His in-laws are overseas at the moment, so he swiped his father in laws guitar to have a strum. Low and behold it is a Sigma DR-28N. It has Martin Sigma USA on the headstock, and says it was made in the USA. That was a suprise, I never knew that they were made in the US. It was purchased in 1985, and looks like it hasn't been touched since 1986! It desperatly needs a new set of strings, but aside from that, I'm as jelous as hell! Anyway, if anyone wants to fill me in on the my lowly DR-2, all info greatly accepted.

Finally a thread on Sigmas! I recently aquired a beautiful near-mint SE-1N and I can't tell you how impressed I was with it. It really surprised me and it was quite a find. UNFORTUNATELY, someone screwed around with the pre-amp and now it will not function without the battery check button being pressed. Any idea on what I could do about this?

Hi, what great forum. I have found little information about Sigma's anywhere else. Sterling, you do have a great knowledge of these guitars with what seems very little information out there to help.

I'm now the proud own of a DM-19 with the "made in Japan" stamp. I'm gathering from what I have read that the top is solid spruce with lam. mahogany back and sides. I'm going to bone the nut and saddle and try ebony bridge pins.

I have a few questions. Can you date the guitar by the serial number? Which serial number do you use? I assume the body one. The number 9 in the model number is still the grading of wood used?

Thanks for the info. and knowledge

My second guitar was a Sigma, but like any kid I swappped and sold stuff trying to find the "perfect" axe. Thirty-five years later, I have gotten rid of all my "fancy" guitars and have managed to recreate what I had when I was younger: 1959 Epiphone Cabellero (my first guitar); 1971 Sigma GCS-6 (my second guitar); 1954 Kay Mahogany Archtop; 1968 Silvertone Archtop with pickup. I gig with these more often than with my Martins and Seagulls.

The one thing that I don't have and never had, but that I want, is an old Stella... but I told my partners at work that the next one to come into the shop is mine.

Oh yeah... my old Sigma sounds better than my 90's Martins. Age does have some advantages.

My Sigma solid body electric guitar looks like the American Stratocaster except for the headstock. It doesn't have the rounded shape on the end. It's brown with the wood grain showing through (stained) and fades out to black edges. White pickguard, 3 single coil pickups, slide selector switch and 1 volume, 2 tone knobs. Adjustable string bridge with a wha wha bar. 6 on one side tuners. A black stripe down the back of the neck. Made in Korea with serial #S99060222. The headstock says "Sigma Established 1970. I have a digital camera and could email you a picture. I don't know how to post a URL for public viewing. Near mint condition, I would say.

And not to change the subject, but another rare guitar I have is an S800 Epiphone with these words wrote across the front of the headstock in black letters. "Epiphone by Gibson" from 1986. Very nice condition too! Can't find much information on it either. I bought a price guide on ebay but neither of these two guitars are in it.

What kind of solidbody?
Strat, LesPaul?
As far as i know, Sigma solids were only produced in the early -70s.
Do you have any pictures(check mine out, above)?

I would say a decent specimen would vary in price from 50£ up to 250£.

I've been to the site badboy recommends. While extensive, it doesn't list every model Sigma produced (see my Feb, post regarding my GCS-6). The site, which I believe is provided by Steve's Music, will refer you to Orion Blue Book, which, for $4.00 will indicated the estimated value of your guitar. I found the same source at my local library some years ago...and again, the GCS-6, was not listed. So what do I believe the value of my old Sigma to be? To most, because I bought a hard shell case some time ago, someone might give me the $135 I paid in 1975 or 76. As evidenced by this site, to many, our old Sigma's value is that of an old friend that will get played once a week because we have a relationship. Is it the best guitar in my house? Of course not. Is it my most valued. Without doubt.

Hey, ... neat thread.

My sigma "52SDM 2" has been through hell. It's been backpacked, camped, banged, burned, baked, dropped, and probably kicked a few times. This thing is a tank and fun to play. It has a full wooden tone with zero tin or ring. It really booms out nicely with banjos, fiddles, and mandos.

Obviously it's one of those 52S's Sterling mentioned. I imagine the 'D' is dreadnaught and the 'M' mohogany. Is the 'S' spruce? What about the the '2' ... it has a paper label, a black painted headstock face ("SigmaGuitars Est. 1970"), no internal Martin stamps, a solid top, and a 8612000524 serial number. I can't figure the sides or back. Great guitar.

Hi,

If Sterling Webb is still out there, can You help me with info on my Sigma. I is a dreadnough, all dark, I was told by the seller (bought it in the early 80s, in Gothenburg Sweden)that it was redwood and jacaranda. I imagine the top can be redwood. The guitar in total is a beauty.

The seller was a guy I used to meet windsurfing and he used to work for the Levin Company until they were shut down (by Martin)in the late 70s.

The guitar is marked on the Label in the Soundhole as follows:

"Sigma Guitars, Est.1970, CF Martin & Company, mod. FW 315 G, Manufactured in ....."

It seems allmost like the label is deliberately torn to hide the rest.

It has "Sigma Guitars Est.1970" in gold on the headstock and also "1.7.82" stamped there (a assume build date)

If You share mail adress with me I can send pictures.
([e-mail])

The guitar has adjustible stable (which i don´t are much for) but it plays and sounds great.

I am also intrested in if Sigmas were ever built in the Levin factory (the building were torn down 2 years ago)

Hello:
What a treat to find someone of Mr. Sterling Webb's expertise regarding Sigma guitars. Thank you, sir, and to all who post in efforts to educate about these instruments.

I purchased a Sigma DR-7 recently. It has a stamped brace (made in Japan for C.F. Martin Co.), no "Ms" or "Ns", but sports an inner paper label where the serial number, 024680, appears, along with the inscription, "Inspected by K. Saigo."

It is a solid top, appears to be spruce, has closed tuners that display the word "Sigma", no veloutte (sp), lots of binding everywhere, and the gold "Sigma Guitars Est 1970" headstock logo.

I was drawn to this instrument not by its sound, but by the wood used for the back and sides. I assume its laminate, but it does not appear to be Indian rosewood. It has the chocolate and butterscotch tones of Brazilian rosewood. Not too swirly, but definitely inconsistent with respect to grain width. Bookmatched back. Dynamic sides. Lovely. It is more attractive and, in my opinion, much more desirable than the tight, straight grained, dark browns and blacks of Indian rosewood.

Mr. Webb, and others more knowledgable than I, please help me out here. I'll add this page to my favorites list and check back in a
day or two. If anyone can help me out with identifying the laminate used for the back and sides, I'd be grateful. Also, the guitar's approximate manufacture date would be appreciated.

Hi Sterling,

Thanks for all the info. I have a DT-4N that I bought new in 1995 and I was curious as to whether you knew what wood the "T" stands for.

Also . . . although I'd like to think the "N" means it was assembled in Nazareth, both the stamp and the paper label read "Made in Korea" and there's nothing to indicate otherwise. Any other idea what that "N" means?

Thanks again for sharing all your knowledge. My Sigma has been my one and only 6-string for 8 years now and I really love it. Good to know there are other fans out there.

    Gator, your DR12-7 has the older 1970-79 logo: a pearl greek letter sigma ("sideways M") and the word "SIGMA" in gold, apparently. If so, it probably has a solid rosewood body and solid spruce face. At least all the 70's ones I've seen do, unless it's a 52S DR12-7. Great guitars, built like a tank and very resonant. Go way upstream in this thread to my short history of Sigma for more information.

    Jerry, is it solid rosewood? First, compare the grain pattern on the inside of the guitar with what appears at the same spot on the outside of the guitar. (It helps if the grain is pronounced or stripey.) If they're the same, it's solid woods (one piece).

    If the guitar has a traditonal endpin (not a screw-in strap button) on the butt end, carefully remove the endpin and you can look at the edge of the sidewood and the endpin hole. Very easy to tell if it's one solid piece or a layered laminate.

    To tell if a spruce face is solid, examine the soundhole edge nearest the bridge with a magnifying glass and a strong light. If it's solid, you can see the grain lines run all the way across the edge and disappear onto the underside of the face. If it's a laminate, the grain lines will not match across the edge or not even be visible. You will also be able to see the seam(s) between the layers.

    But the important thing is how the guitar sounds, not the construction details. Yes, as a very general rule, solid is better, but the very best sounding guitar I own has a solid rosewood body and a bi-layer spruce face. It's a hand-built from 1974, made by one of the original luthiers at what became Taylor Guitars, Bob Mossay. After listening to it, old Martins crawl off in a corner and sob uncontrollably...

    Yes, I have other guitars besides Sigma's: Yamakis, Daions, Harptones, G. J. Goulds, assorted Japanese made oddities, a couple of unidentifible guitars, two Harmony's, a pre-war Regal, a few Dobros, Kronbauer, and two of Ted Thompson's wonders, one banjo, and a partridge in a pear tree. I think know a good guitar when I hear it. And like people, they're all different.

    I just bought a Sigma DR-15 like the one described (above) by Bob Spradlin, on eBay (naturally). I just got it today and even with black and ancient strings, it sounds good. In virtually mint condition. It has the GenII logo, so it must be 1980-84, but the serial number is lower than Bob's 1978 model! That's the kind thing that drives ya crazy about Sigma's...

    I can hardly wait to get new strings, ebony pins, and a bone saddle made for it. Drool. Unlike Bob's, it doesn't have an abalone rosette, but does have the herringbone bindings and backstripe, pearl snowflake dots, solid body and solid face, and what looks to be a one-piece neck. It came with the original case which is wood covered in real leather.

    One really odd thing: it has modern sealed tuners (original, not replacements) but instead of cylindrical bodies and caps on the gear drives, they have hexagonal bodies and caps. Very strange. Never seen hexagonal tuners before anywhere.

    CLM, the "N" on the end of your DM-2 interests me. In the older Sigma's the "N" meant a model that was actually assembled in the Martin factory at Nazareth! Look inside on the neck end-block to see if there is anything stamped on it. I had (sold) a DR-35N that had a Martin logo there, with "Made in USA" and a 6-digit serial number. These older "N" models were re-labeled Shennandoahs.

    How'd I learn so much about Sigma's? The hard way. I've bought about 40 Sigma's on eBay. (Yes, 40; fix their problems, set them up, send them on their way again.) Er, some I kept -- too nice, or too much money invested. I also buy up old Sigma catalogs for information, and I scrounge the net for data, too. The really good (rare) Sigma's are possibly the most undervalued high-quality guitars around.

Wow. I guess after 2 years of trying to find out about my DR-28, I guess there isn't much more I could learn. Except when it was actually made to the month and year.
I bought it new in January or February of 1980. It has a body serial # of ES22477 and a stock serial # of 034065 K. Since it is possible it was made in 1979, could it be made with solid rosewood sides and back?

If anyone knows, could they e-mail me at [e-mail] to let me know.

Just a thought, but being as this thread seems to have "outed" LOADS of us Siggy fans, do you think it's time to pressure Martin into re-establishing the strong links they had with then a few years ago, and AT LEAST MENTIONING THEM ON THEIR WEB SITE!!! Or is it that the low end modern Martins don't measure up to the Sigma's!!! Ooooh I DO so like starting a good slagging match!!!

Thanks for the Info. I seem to remember the salesmen at the store I purchased it at said it was a limited edition. To me at that time it didn't mean much. It looked good, sounded good and the price was reasonable. I never regretted that purchase. As for the wood, you have to be right....I was mearly guessing. I am assuming abalon inlay is what my back seam is only because it's different then my top edges. I remember the salesmen telling me that the top edge was a herringbone inlay. So I guess I will keep my eyes open on eBay for another DR-15 and grab it if I can. Thanks for the tip on strings...I always use light strings anyway but now I will not feel bad about tuning it up.

    Bob Spradlin, another mystery Sigma, the DR-15! It has to be Rosewood (that's what the R in DR-15 means). Your description of the DR-15 sounds exactly like my mystery Sigma, except that instead of herringbone inlay for the top binding, my "mystery" Sigma has abalone inlay.

    These "mystery" Sigmas must have been made in very small quantities (or they wouldn't still be mysteries). I knew about the DR-9 and DR-11, but the DR-14 reported here was news to me and now, a DR-15! That's two more models I didn't know about. I haven'e found either one in my collection of old Sigma catalogs. That's another reason to suppose they were only made in small numbers, if they get in the catalogs.

    Since the "15" is what Martin called a "quality" number, it's as good as you think it is! I don't know if you have to tune it down so much as to make sure you never use strings heavier than Lights. Light strings have only 75% of the tension of Medium strings at the same tuning, and I've seen evidence that the use of Mediums will damage Sigmas over the long run.

    R. W. Maiden, all I can tell you is that you have a solid wood mahogany Sigma in the DM-4S. I concentrate on buying the Japan-made Sigmas, so I haven't had the chance to look over Korea-made Sigmas. The serial number suggests it might be from the mid-80's, when Martin and the Japanese manufacturers were setting up their joint Korean factories. In a Japanese Sigma the "S" would mean sunburst finish. Today, the "C" would mean Cutaway. Is it a cutaway?

    The "sideways M" logo means Made in Japan between 1970 and 1980. These models are usually the most valued Sigmas, so it was probably a good one. The "214" is probably an internal stock reference and doesn't help figure on the model. Sorry I can't be of more help.

S.Webb. Thanks for sharing all the info about Sigma guitars. I was curious to know if you could shed any light about my Sigma. It is a DM-4S (as in Sam) model and also has a "C" designation after the model. The embossed stamp inside says it was made in Korea for Martin and Co. The two serial numbers stamped inside are 286850 on the body and 804158 on the base of the neck. What makes it different is the top is Mahogany sun burst. I don't know if this is unusual or just an option that was offered. I, like many others, am pleased with the sound quality of this guitar. I would appreciate any insite or information you might have on the particular model.

I have a Martin Sigma DR-15 S/N 35039 I bought brand new in 1978. This has been and remains a sweet sounding guitar. The neck is as straight as the day I bought it. I have kept the guitar tuned low to reduce stress to the neck over the years. It has pearl snowflake fret board buttons, Solid spruce top, looks like walnut sides and split back with special inlay in the back seam. It is made in Japan. The edges of the guitar have a Herring bone inlay, abalone inlay around the hole, ebony pegs and rosewood fretboard. Does anyone know anything about this guitar? I wouldn't sell it for anything and everyone who plays it wants to keep it. I would say this has been the best investment I have ever made in guitars. How much is it worth, and any history on it would be nice. I am shopping for another one just like this one but I cannot find any information let alone another DR-15.

    Some (partial) answers to some of the earlier questions in this thread.

    Early serial number DR-7's. My DR-7 bought in March, 1970, has the serial number 6860, so a DR-7 with the serial number 6806 should be an equally early one. Two things to look for in a very early model: a "zeroth" fret right in front of the nut and a printed label with no place set aside for model and serial numbers, so they are just ink-stamped on it whereever there's room.

    S. McBay, what is your DR-7 serial number? Numbers up to the low 10,000's are probably before 1974. Sigma serial numbers were neither consistent or continuous, though. I have a 1974 DR12-7 with a serial number 74xxxxxxxxx, eleven digits, and had a 1980 one with a 29,xxx serial number!

    Sashi4, the CB-5 is a classical guitar is made of Bubinga wood. I don't know what the AC-10 stands for, but the two CB-5's I've seen (on eBay) were also stamped AC-10, maybe a manufacturer code. They're from the early 1970's. Sigma never put the logo on the front of the headstock of the classicals.

    Price of Anniversary Model: In varying condition, I have seen them (on eBay) go for $150-$200 with dings and scratches and other detracting features and up to $300-ish if minty. I actually paid $375 for a dead mint one with the original Martin factory case they came with if you bought one from a Martin dealer, but then I'm a Sigma nut, as is plainly evident.

    An old beatup DM-5 from the 1970's is just about the best sounding guitar for the dollar you can get: solid mahogany and solid spruce face, yet they rarely bring more than $150 on eBay. Invest in a set of ebony bridge pins and a good hard saddle (brass or bone) and you'll have sound that would be hard to match at four times that cost in a new guitar.

    Guest! Re-finishing an older guitar (Japan-made DR-28H) tends to re-set the clock on any collector value it may have now or in the future unless there's really horrible damage. It's also hard to do well on a nitro high-gloss finish unless you have a lot of experience with the task. A lot of things can be buffed out of a nitro finish, though. Check with a luthier.

I have one of the bottom of the line Korean made Sigmas.
It is a DM-1B. A black guitar. I bought it for $75. I
needed a guitar I could travel with and not worry about
getting banged up. This guitar is built like a rock. I
have bumped it alot of times with no damage at all. I
have also realized that it is my favorite guitar to play.
I loaned it to a friend of mine who is a banjo player
so he could learn a couple of Tony Rice songs. He has
has it for two months and I truly miss the guitar. It
is an excellent guitar for the price. I have others that
I refuse to play that are more expensive that the Sigma.
Now I play my Martin while looking for another Sigma. Not
to say that the Sigma is better sounding than the Martin
but my Martin costs too much to drag with me.

just my two cents...

I would recommend this guitar to anyone. Even though mine
is Korean made, I would look for one made in Japan.

BTW, I'm saying grab it if it is one of the DR 41 made in Japan models that was mentioned by Sterling in his excellent summary of Sigma guitars above. Like I said, I lucked out with the one I bought, it seems to be one of the rare gems of the 1980-19084 models, that obviously came from one of the better manufacturers. My guitar oozes character, which is why I'm hanging onto it.

Not a pro quality guitar, as everyone else has noted. But damn near perfection for the price, action, and sound factors, especially over time. I never expected an inexpensive guitar to age as gracefully as this baby has--it's one sweet guitar.

I've got the Sigma DR 41, made in Japan, bought in 1982. I got it because after selling off a couple of Martins and Strats from my bar band/partying days when I was broke, I didn't think I was worth spending the money on for another Martin, since I was only playing for pleasure for myself, family & jamming with friends.

It's funny how my feelings have changed about this guitar over the years. When I bought it, my thoughts were "a cheap version of the Martin" even though I brought several folks into the shop to hear this guitar, and we all agreed it just seemed to good to be true for the price.

Nowadays, I realize I have a guitar every bit as good sound and action wise, as most Martins I've ever played, regardless of the model. Everybody who picks my Sigma up says that too, so I know it isn't just me trying to make myself feel better about buying the cheaper version of the Martin D41. And just like the best old Martins, mine's only gotten better with age. It is one sturdy bugger too. I finally broke down and bought a high end case for it about 10 years ago, when I decided me and this guitar would never be parting, and I needed to start treating it with the respect it deserved.

Mine has GORGEOUS sound, especially bright with a new set of strings, and especially for the sound it has for playing trad, bluegrass, walkin' blues...it's as good as anything I've ever played.

Grab that DR 41 and ignore all the "it's only a cheap Martin rip-off" talk. If you love the sound and action of it now, and it seems to be a guitar with personality and is structurally sound (you know, top matched to perfection, that sort of thing) to the point of the guitar seeming too good to be true, BUY IT! I guarantee it will age beautifully for you. You can tell some of these Sigmas are made by true artisans. If you are lucky enough to find one those, you'll only be more pleased with the brilliance of your purchase as time goes on!

Sigma guitars are good - but making comparisons with Martins doesn't do them justice. Compare them to other guitars that cost the same (or less) than Martins to get a true impression of their value.
Martins are over-hyped and over-priced.

Subject: RE: sigma guitars
From: GUEST,Sterling Webb
Date: 03 Nov 04 - 11:01 AM

Hi,


Daniel is right. The naming scheme for Sigmas was originally by size, composition, and quality. The sizes were Dreadnought (D), Grand Concert (GC) or 000, C for classical, and so forth. R is for rosewood, M for mahogany, S for sapele, B for bubinga, J for jacaranda. Originally 7 was the highest quality grade.


So, a DR-7 (the top of the line) is a rosewood dreadnought of top grade, the DM-5 a mahogany dreadnought of lesser grade, and so on.


In 1980, the model lines and designations were changed to capitalize on Martin model names: the DM-18, DM-19, DR-28, DR-28H, DR-35, DR-41, DR-45. But the older model types were also continued as well for another 4 years (1980-84).


My guess would be that the DR-14 is a souped up DR-11, just like Daniel surmised. I've never heard of the DR-14 before so I get to add a new one to my list. I've heard the DR-11 called the rarest Sigma model (just one on eBay in the last 2-3 years), but a DR-14 would have to trump that for rarity!


I've just bought a Sigma that I can't identify. It has the old-style (1970-79) logo with the word SIGMA inlayed in pearl instead of the usual gold leaf, something I've never seen before. It is solid rosewood and spruce, with a Martin-style bridge (not an adjustable thingee) and with pearl snowflake dots on the fretboard and abalone inlays around the soundhole and top bindings. It has a "normal" (two-piece) back and encased tuners (not sealed). It's missing its paper label, so it's a mystery model with great sound.


If anybody has ever seen one like that and can help me identify it, please reply.


Many of these higher quality models appear to have been produced in very small numbers (like 100 to 150), at intervals, as needed to fill in the high-end of the dealer offerings.


Sorry I hadn't figured out the page breaks (first-time poster) and it all came out in one lump. I think I've got it now.

Hi everyone, I'll try and add my two pence in! I presume the D in DR 7 stands for dreadnaught. The R will stand for Rosewood and therefore if you have a DM model the M will stand for Mahogany. I could be wrong but I'm pretty sure that's what it all means.

Now I've got to ask for some help. I've a a DR 14 , it has a three piece Rosewood back, and Rosewood sides of course. It is stamped/burnt made in Japan with a serial number of s21713 but also another serial number of n060100 inside on the neck. If any of that makes any sense. It has Mother of Pearl (the multi coloured kind) inlays, and also round the hole of the guitar and edging round the guitar. The machine heads also have Sigma stamped on then.

It's very similar to the DR 11

I can't find any information on the DR 14 and it's driving me mad. Harmony central has lots of reviews on guitars but alas not the DR 14. I would love to know if anyone else owns one or knows anything about it. Please.

Mr. Webb. Your history lesson on Sigma's is most informative. It is the most complete anthology I have read to date. Thank you for taking the time to post. Sigma appears to have a varied history with a large "window" of different construction methods and wood grades used. Was the DR-7 a dreadnaught "replica", as I was told the DR designate stood for? Do you know anything about the composition of the different finishes used throughout the history of the line?
Thanks again for the info.

I can't help contibuting to a thread about my favorite obsession: Sigma guitars. In the late 1960's there was a strong increase in demand for guitars in the U.S. Martin could not increase production of U.S. made guitars because of the time lag imposed by the need to season hardwoods. The Japanese manufacturers, having saturated their domestic market early in the 1960's, had abundant stocks of seasoned wood on hand. Martin began selling the Sigma line of Japanese made guitars in January of 1970. Sigma guitars made in Japan from 1970 through 1979 can be distinguished by a headstock logo consisting of the single word "SIGMA" surmounted with a greek letter sigma ("sideways M") and an inner paper label giving model and serial numbers. These early models are almost always solid wood guitars, and tonewood of a high grade at that. The early models are encoded by size, wood, and quality-grade number; that is, a DR-7 (the top of the line) is a rosewood dreadnought of top grade, the DM-5 a mahogany dreadnought of lesser grade, and so on. In 1980, the model lines and designations were changed to capitalize on Martin model names: the DM-18, DM-19, DR-28, DR-28H, DR-35, DR-41, DR-45. But the older model types were also continued as well. The headstock logo was changed to the present day form ("SigmaGuitars / EST. 1970"). The models made between 1980 and 1984 in Japan are almost always solid top with laminate back and sides (like Shannendoahs), as the Japanese manufacturers had used up their stock of seasoned woods by 1980. The paper labels were dropped in favor of stamping the back brace. In 1984, production was shifted to Korea, and in 1993-4 to Taiwan, where it continues to the present day. In general, the quality of the guitars declined in Korea to a medium or lesser grade level. A few Taiwanese (like the DR-28) are surprizingly good, but they're rare. It is worth noting that all the currently produced Sigmas except the DR-41 are designated with the quality grade of 1, meaning there is is no lower quality possible, a curous honesty on Martin's part! Which old Sigmas are worth buying? Here's a guide. The most desirable vintage Sigmas are almost any of the "old logo" Japanese made models: the DR-7 (a D-21 clone), the GCR-7 (a rosewood 00-21 clone), the DM-5, the CR-7 classical, the DR12-7 12-string. The first Sigma catalog (1970) also shows a DJ-7, made of jacaranda or Brazilian rosewood, but I know of no one who has ever seen one in the flesh! Secondly, 1980-84 Japanese made DM-18, DM-19, DR-28, DR-28H, DR-35, DR-41, DR-45 are all excellent guitars but are sometimes inconsistent: 1981-83 DR-41's are laminate; the 1984 DR-41 was solid woods! Where they are laminate construction, the veneers are of high quality and it's often hard to distinguish their sound quality from solid wood. (When in doubt, remove the end pin which will expose the edge of the side wood to inspection.) In 1980, Martin produced 100 Anniversary Sigmas (model 10), a solid mahogany dreadnought; equip one of these with a brass or ivory saddle, ebony bridge pins and medium strings and you can hunt down D-18's in the heaviest brush and stomp them to death --- it's a very loud and impressive guitar! In 1981-82, Martin produced a small number of models labelled "MartinSigma / USA" and designated by an "N" at the end of the model name: DR-28N, DR-35N, etc. These were made in the Martin factory in Nazareth, PA. If Martin makes a Martin clone in the Martin factory with Martin serial numbers stamped on the neck block, does the word "clone" have any meaning anymore? They are just re-labelled Shannendoahs, a pretty good guitar. The DR-7 model was also continued through 1980-84 in Japan, with the addition of a DR-9 and DR-11, all made in very small quantities. They sound about as good as an average Martin D-28 of the same time period (not their best period, I admit). Also made in small numbers in 1979-81 were Sigma models with the prefix 52S, as in 52SDR-7. Curiously, they are made entirely from some very strange laminates. The 52S series were sold as "professional" instruments; they have a pure clean resonant tone (like a high-end maple Gibson) which combines well with the human voice and records cleanly without a fuss. (I've had three of these, and all had thoroughly rigid construction, dead straight necks that had not moved in 25 years, low fast action, and great playing ease, as well as fine sound.) I have have owned, played, bought, sold, traded about 30 Sigmas, which include most of the models mentioned above. Because the high-quality Sigmas were made in small lots by a variety of Japanese manufacturers, there is considerable variation from one instrument to another, not in quality but in character. I have two 1980-84 DR-7's. One sounds pretty much like a slightly sweeter version of a D-28. The other sounds like a 1930's Custom Shop guitar (like that B&D Senorita that keeps popping up or an old Vega). My first "bought new" guitar was a Sigma DR-7 purchased in March, 1970 from a Martin dealer and one of the first 100 Sigmas sold. (Martin shipped exactly 100 Sigmas to dealers in 1970!) It cost $139.95 plus tax. It sounds better (to me, at any rate) than all the other Sigmas I've owned, save one. It has a number of construction details not in common with later DR-7's, so it's possible that it would be worthwhile to search for the lowest serial number when shopping for a DR-7. If by the Martin sound, you mean (and most people do) that crisp percussive snap of attack on the bass strings, the only Sigmas that approach that particular quality are the early DR-7's.

I concur, Spike. (Just some background information) I owned a couple of guitars through my teen age years (Fender and an Ovation), but they had been purchased second hand. When I was in the service and could afford to buy my own toys, I saved specifically for, and purchased, my first (as I thought) "real" guitar, a D-28 Martin. It was a great guitar I have to admit; however, it did NOT make me a better player. The guitar, along with every other thing that was of value to me was lost in a fire in '81. I had decided to purchase another Martin, but, quite by accident, I mistakenly picked up a Sigma sitting next to a Martin. I played it and thoroughly enjoyed it. I hadn't realized that I wasn't playing a Martin until the owner came back to me and said, "For a knock-off, they're pretty good, aren't they?" I looked at him like he had three heads or something. (It should be obvious to you now that I am not a professional.) I know I play well, but the only person I've ever entended on entertaining was myself. It hit me right then and there that, if I couldn't tell the differance between this and a guitar that cost $2000 more, why should I pay that? I played a few of the Sigmas and ended up purchasing the DR-18. Everyone that has heard me play it (Mostly family) thinks its a great sounding guitar. I think so too. ...just some imput from a non-professional who enjoys playing.

I agree with you Spike. Perhaps too many students think that if they trade thier Chevette for a Corvette, they can travel along at a nicer pace (they still make chevettes?). I think if the axe does what the person wants it to do, brand or price should not play a factor. As a player progresses and thier style develops, they will find that thier needs of the guitar will change as well. One secret I use when determining a good guitar (aside from action, intonation etc.) is to try to feel the back vibrate against my stomach when playing at a moderate level. I guess resonance would be what I look for. Of course this only applies to acoustic axe's. When I have good resonance, I don't have to work near so hard to get the sounds I'm looking for and can get a better dynamic range out of the instrument.

Yes, good point Mooh, but As my earlier posts say, SOMETIMES you don't need to move on to something better, and it breaks my heart to see young 'uns desperate to buy a "name" on a guitar, thinking it will make them better players!! That's another can of worms, the "I must have a Martin,Taylor, Guld, Santa Cruz, Collins to be a proper musician" mind set, which bugs the nuts off me as well, as my Sigma is owned by choice, not by price, and it would be interesting to hear others views on this.

A Sigma showed up this season in the hands of a young student, apparently it had been his mother's. It is well intonated, has decent action, but the sound is no better than a million others from the import market. Young ears don't much care about that though, they just wanna rock. And there's the rub, how to balance all the properties of playability, durability, sound, and appearance. If a guitar such as this pleases someone, there's a market. Maybe in time those young ears will want something better. Hook 'em with something cheap, the big money comes later.

There's a part of me which sometimes likes a funky old rotten sleezy guitar sound, but not often. Maybe there's a place in every collection...

Thought I'd leave an update on the busted Sigma. I since found out this busted sigma was somewhat considered a write off. The top was broken along both sides of the neck block and considered a fatal break aside from replacing the top.
Not to be swayed and what to hell..."nothing ventured nothing gained" so away I went with my wife's steam iron in my hand and a piece of clean rag. Since the back had become unglued at the neck block, I decided to remove the back to better see the "fatal wound".
After applying lots of heat,( lesson #1...don't get your iron too hot!It discolors the laquer.)I was able to get the back off with no damage to the kerfing. Applying water to the inside seam with a syringe helped considerably. Sure enough, the lower side of the top was broken right through and the upper side of the neck block was broken as well. To compound things, one of the cracks extended right under the neck block and was inaccessable without removing the neck/fingerboard.
Gently pulling the neck of the guitar in a lateral motion, I was able to get the broken top back into it's original position and set it with a couple small dabs of superglue. The upper brace had also broken away from the top.
After several hours of pondering the problem ( I have too much time on my hands), I finally decided that the only way to regain integrity was to "extend" the portion of neck block to include more top area. My reasoning was that 99% of the guitars sound comes from the larger body area near the bridge, I may be able to distribute some of the neck pressure across a larger area of the top with minimum ill effects to the sound. A strip of spruce top reinforcement had to be shortened to accomodate the "wings" I was about to add to the neck block. The "wings were made out of a piece of pine similar to doorstop material. It was sanded into 2 pieces about 3/8 " thick, 3/4"wide and approx 2.5 " long. these were glued to the neck block and the top at the same time with the 3/4 inch side on the inside of the top. Next I had to secure the main brace to the top again. To give it some added strength, I cut two small triangular pieces to repair the cracks extending down to the sound hole. These were made from a piece of eastern white cedar which was split down to approx 1/16" thickness, then sanded smooth then glued cross-grained to the underside of the top once again. Two pieces were used to ensure access to the truss rod adjustment but 1 piece could have worked as well.
Satisfied I had done all I could to keep the neck from moving, I turned my attention to the rest of the guitar. I was right about it being bulletproof. As a side note, this sigma had a mahogany plywood back and sides and was not given the designate DR-18. I still think the Dr-18,28,35,& I can't remember a 41 or 42 all had the solid back and sides as well as solid top.
Anyhow I digress....the glue job was sloppy with drips left all over the place, the gause support at the cross brace junction was extremely large and extended down on to the bridge plate. The bracing was pretty much standard martin braces and don't spare the glue. A support was placed down the center of the top like a running cleat to avoid the top from ever splitting or cracking. The bridgeplate was made from rosewood plywood once again dripping with glue when it was applied originally. This will never do so I took my trusty knife and proceded to cut away any cheesecloth support that was in contact with the top or bridgeplate and cleaned any large drips of glue that was visible. Then with a dremel tool I proceeded to scallop the braces into something like a cross between the old pre-war martins and thier more modern design.I took out a considerable amount of wood all the while wondering am I doing the right thing. I had some examples of pre-war martins and current bracing patterns but I had to adapt the slightly different brace style in my scallops to fit the newer style of brace. Satisfied that I had taken all I dared to out of the braces, I turned my attention to the bridge plate. Well, fools walk where wise men fear to tread and I was jogging pretty good so out came the dremel again with the sanding drum and on to the bridge plate. I didn't think it should be glued to the X braces as well as the top so the whole bridge plate got a bevel job except for the strip where the strings poke through. I left a piece untouched about 1.5"wide along the whole length of the bridge plate directly under where the bridge glues on. Whoops....the grinder hit the center support cleat that run the whole length of the top. And then it hit it again. I own a guitar made by luthier Marc Beneteau and it don't have those cleats so off they come.A little hand sanding along the braces to skinny them a little more and it's time to replace the back before I go too far...if I havn't already. Ok...back is glued on but I still am not satisfied with the resonance to guitar makes when the top is lightly tapped with my fingers around the bridge. Time to get rid of that glossy plastic finish. I get my sanding block and see it has a used piece of #80 grit sandpaper in it. Now it took a real act of courage to take a perfectly good looking guitar and run a piece of sandpaper across it. I closed my eyes and decided to scuff the top once so I couldn't chicken out. As the sanding block hit the top of the guitar, it was very much like hitting a piece of window glass. I opened my eyes and looked in amazement at the tiny little scratch this sandpaper left on the guitar face. With a renewed vigor I attacked the top once again only this time with my eyes open. It was like trying to sand lexan or plexiglass. About an hour later and a couple sheets of sandpaper I managed to take off about 2 cups of plastic off the front of the guitar. Tapping the top once again, success, the guitar was starting to sound like a drum and not a block of wood. With a renewed enthusiam but still guarded that this thing was not going to fold up after I put the strings on it, I went at the back of the guitar. I think I got about 2 cups of shavings off it as well. A small increase in the resonance was noticed but not near as dramatic as when the top was done.
Off to town I go to get new strings and hope this thing works out. After all, I've put quite a few hours cutting, sanding, glueing etc.
By my calculations, the strings are going to be way too high to play comfortably and the slot in the bridge don't appear to be deep enough for me although I don't have a spec to how close the saddle should be to the actual guitar top itself. This one looks like the slot is cut too shallow in the bridge. Oh well I can't wait I'll shave the bone down to get the correct height and maybe after
i get a spec someplace I'll modify as needed. The neck releif looks pretty good so time to string it up and see how it sounds.

I am happy to report that the guitar does not go out of tune, is still holding (3 days now)and I am tickled pink with the tonal response and volume. Not very much bass ( I'm used to rosewood bodys)but very well balanced all the way up to the 14 fret. It is very much like playing a new guitar and over the last 3 days the tone has improved noticeably as well. I'm sure it would fool the most passionate D-18 fan into thinking it was the "real thing".
Anyhow...I don't know how long this stripped down "hotrod" will hold together but I'm sure enjoying it until then.
No Guts ...No Glory.
Thanks all...I'll post again sometime to give you an update.

I owned an early 80's Sigma dr-35. It was stolen however, I have been on the lookout for any older Sigma dreadnaught, models Dr-18, Dr-28, DR-28H (herringbone bindings), another DR-35 or the DR-41 ever since. These were all solid spruce top replica's of the Martin dreadnaught line and the top axes of the Sigma line as well. The main difference I could see between the two (martin and sigma)was the composition of the finish. The sigma finish seemed to be heaver and tougher and not as apt to check in the cold and considerably more durable at the price of less resonance with the top. Other than that, I think they were identical to the martin counterpart except in price and re-saleability. As of this post, I cannot difinitvely say back and sides are solid or ply however, happy days are here again.
I finally found a DR-18 that some guy sat upon and broke the neck block or at least somewhere near that area. The back also started to "pop" out of it's binding at the area where the neck meets the body. Ma The guitar is in rough shape and is going to require extensive repairs, however I'm hoping it was not put together with exoxy or something that won't soften up with heat. It is also the perfect excuse to grind off all that heavy finish that made most Sigma's bulletproof and try to allow the top to resonate like it's american counterpart.
I have also had the experience of playing some of Sigma's lesser line such as the DM-3 and found the plywood top Sigma's were pretty much a beginner's guitar and not really suited to more experienced players and no amount of re-work will ever make them better.

Anyone having any experience in repairing Sigma's I would be most interested in hearing your findings on how easy they come apart.

I have a Sigma DM-18. It is stamped Made in Japan by Sigma for C.F.Martin and Co. Serial number S 42319. I purchased it new in 1981. I have no idea when it was made. It is the best tonal acoustic I have ever owned.

I read somewhere once that Martin started building Sigmas in 1970. I forget exactly when they started in Japan; however I do remember that they moved the Japanese operation to Taiwan in 1984. The article said the quality suffered with the move. I played a couple of the Taiwanese Sigmas. They fall extremely short of the Japanese built ones.

I haven't payed any attention to the model numbers, years they were built, etc.; but if you find out when/where it was built, and it was built in Japan, I'm sure you'll be happy with it.

It has the rosewood back and sides, but one tech told me that the backs and sides could be solid as well as the top. He really had a high praise for these jap knock-offs.

The wood has had a chance to age nicely, and when i heard it in the music store, it took the gold medal as far as sound goes. A loud/projecting sound. Bang for buck was a no brainer. The Japanese ones if you can find a good one will sound very nice. Change the bridge saddle to a Tusq or bone one, and use some good strings, and you will be amazed.

This apparently accounts for the huge volume from the beast, but he also agrees that there's bugger all difference in the sound of mine to a Martin.

I've recently acquired an old Sigma.
Made in Japan so I'm guessing 70's.
There are very small traces of the serial number left but not enough to read,so nailing it down to a year is pretty slim that way.
On the center strip is burned/printed "SIGMA GUITARS Made in Japan for C.F.MARTIN & CO."
The model # is a DM 3.At least I'm about 90% shure it's a 3.
Anyone here know if & when Sigma made a DM 3?

I haven't done an in depth search on the subject yet,but so far I haven't found any info on a DM 3.

This guitar was offered to me as a "parts" guitar for ten bucks.
It was stripped of all it's hardware & had spent the last 15 years of it's life sitting in a barn. Luckily,it appears that some of that time must have been in a case.
Once I cleaned off years of dirt & grime,I discovered I'd actually purchased a good solid instrument with an amazingly straight neck.

It's got plenty of character in the way of nicks/dings/scratches,but once I rounded up & installed the necessary hardware,she came back to life with a very sweet voice.

This Sigma never was & never will be a high end guitar,but I'm real happy with this old ten dollar "beater".

Sigma were the official Martin budget line.

Here in the UK you can probably get a used Sigma DM2 for about £120, DM4 about £200 - both streets better than any new guitar at the price, with quite a fair impersonation of the ringing Martin sound.

I refurbished a DM4 for my daughter with a shadow pickup and a fishman preamp and it is nice. I have told her if she ever decides to sell it I will give her £500 for it.

A very basic L'Arrivee will cost you about £500. A top of the range one, about £2,000. I don't call that "low priced"

I've never met a Sigma that I liked. Looking for a good low priced guitar? Larrivee.

Have a look at this site:
Blueridge Guitars

This is a fine line of guitars, equivalent in sound to others costing 3 times as much. Two of my friends who are long time bluegrass pickers, have bought these, and use them instead of their martins...

About 15 years ago I bought a Sigma, modelled on one of the smaller-bodied Martins, and it has served me very well ever since. Its tone, volume, playability and intonation are better than a number of more expensive instruments that I have played over the years.

I believe Sigmas were (perhaps still are?) made in Taiwan, but to Martin specifications, and using Martin-supplied tools. Of course, their sound is not as rich and subtle as you can get from a well-aged Martin, but how many of us play well enough to deserve one of those? If you can get hold of a good Sigma, Allison, grab it with both hands.

Wassail!

I bought one in 1980. It was the model that was copied off the Martin D12. I liked it a lot. It was well built and had a nice tone. A friend of mine had a real D12. The only big difference I could discern between the two guitars was the Martin had a richer tone on the lower strings.

Sigma Guitars were distributed by Martin and varied in construction from low end with laminated tops to high end solid wood such as the sigma 41 and 45 models. Thes were excellent guitars and I sold a good number of them in my store. I found them quite comparable to even the Martin in tone and quality. Hope this helps a little.

sigma guitars are still available in the uk - sound control in Leeds stock quite a few- the earlier models were made in the far east but assembled by Martin trained techs also the early ones were made from martin parts and were the marquis range at a higher quality - a pal has a very early one and it comes close to martin quality in sound and playabilty and IMHO they are better than some of the budget martins currently available

Martin bought out the old Levin Guitars (Sweden) and carried on making Guitars there for a while under the name Sigma . A mate has one that works very well , though perhaps not up to the higher range Martins , a perfectly workmanlike instrument .

Back in the 60s Sigma Guitars were highly regarded in NZ - but that doesn't mean much. Tone etc was fine... Can;t help you on current availabilty in the UK - but would bui one - ikey probabbly cost a few quid now,,,,
