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.
