1970" underneath in a smaller block font, in the familiar Martin headstock decal form. re: My own first Sigma, a DM12-5, which I purchased new in mid-1977 (I still have the receipt) had this second gen "Martin style" decal logo.

It being a smaller, local store, the instrument may have been sitting there for a while before I acquired it.

The answer to the question "Are Sigma guitars solid wood or laminate?

" is best answered "That depends on the year and model." It is safest to assume that the Sigma in your hand is made of laminate sides and back, however it has also been said that some of the earliest Sigma's were made completely of solid woods.

75XXXXXX possibly equates to a build year 1975.) It is widely assumed by owners and Sigma historians that this is correct, though C. These instruments were constructed using preformed and sometimes partially assembled imported parts, built or completed in the C. Martin factory in Nazareth, Pa alongside the regular production line Serial numbers for Sigma guitars built in Korea and Taiwan are perhaps meaningless, though again some seem to indicate the year of manufacture (e.g.

81XXXXXX.) Since we know these instruments were manufactured from 1984 through 2007 in these two countries, it is safe to assume that a serial number beginning with 81XXXXXX was not produced in 1981.

Dreadnought models DM-5 and DR-7 are the most common early Sigma guitars until the late '70's.

The first Sigmas were typically dreadnought acoustics, although Grand Concert Series (GCS) and classical models were also produced from the early 1970s (1971) onward.All other text was printed in black ink, or stamped on in ink by the manufacturer (model and serial numbers.)From 1980 through 1983, the end of Japanese production, the back center brace is pressure stamped, or "branded" in a football shape stating Sigma Guitars/Made in Japan/For/C. This may be due to them being built in several Japanese factories at the same time with no coordination in the serial numbering system.However, while some models lasted the entire run from 1970 through 1983, others did not and were only offered for a limited number of years, so that most models' construction dates can be narrowed down to a reasonable range.While I cannot be absolutely certain of the year it was manufactured, it was certainly by, or prior to 1977.High end models such as the D-10 Anniversary model have the "Second Generation" logo inlaid in the headstock using mother of pearl. Some of these guitars also had the "Est 1970" instead of the C. Martin & Co.," but in a slightly different block font (fatter/wider) from the original 2nd gen instruments.

This is understandable since the Martin customer service department now responds to individual inquiries stating "all" Sigma's had laminate back/sides with solid tops, while Sigma catalogs from the early 70s list the back/side wood as solid.
