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......:)
