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).

thanks

Dustin

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. Because the Martin Co. does not deal in the used or vintage market we do not appraise instruments. Please contact a dealer in your area that deals in the used market.


Thank you,
