Sigma-Martin USA guitars built in 1981 and 1982 had serial numbers 900,001 to 902,908. A guy at a music shop said some of those sigmas could be worth a few hundred bucks. Id like to have an idea on it before i try to fix it myself.the serial number is 87110807 on the paper tag in soundhole that also says c.f. It has the sigma guitars est.1970 logo on the headstock.any info would be appreciated. History Initial construction was in Japan by various manufacturersfactories from 1970 through 1983. The first Sigmas were typically dreadnought acoustics, although Grand Concert Series (GCS) and classical models were also produced from the early 1970s (1971) onward. Dreadnought models DM-5 and DR-7 are the most common early Sigma guitars until the late 70s. D for dreadnought, R for rosewood, M for mahogany and the number denoting the grade of wood, 5, 7, 9, 11, 15. Construction moved from Japan (197083), to Korea (1984-9394), and finally Taiwan (19932007). In 1980, model designations were added to capitalize on Martin model numbers: the DM-18, DM-19, DR-28, DR-28H, DR-35, DR-41, and DR-45. The DM-5 and DR-7, as well as other early models continued to be built during this time as well. Headstock Logos Sigma guitars made in Japan from 1970 through 1983. The early 70s models (1970 -1975) can be distinguished by a headstock logo consisting of the single word SIGMA surmounted with the symbol (the Greek letter sigma), in mother of pearl. Interestingly, while playing a Sigma guitar the sideways M becomes right side up suggesting M for Martin. By the mid 1970s (c1976) the headstock logo design changed to utilize a gold Martin style decal stating Sigma Guitars in script with Est. Basses As is tradition in classical instruments, Sigma classical guitars do not have the headstock logo, and one must rely on the inner label for identification. Labels and Brands Sigmas made in Japan from 1970 through 1979 used a paper label to identify the model and serial number of the instrument. The earliest examples had a plain black on white inner paper label giving the model and serial numbers. ![]() 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 GuitarsMade in JapanForC.F. Martin Co. followed by an ink stamp of the model number, and prefixed by the serial number assigned to the instrument. L-R as seen through the sound hole: Serial number, Brand, Model number.) Early Korean made guitars show this same brand, only Made in Korea in place of Japan Serial Numbers Sigma serial numbers do not provide an indicator of the year in which a particular model was built. 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. For example, serial numbers on the earliest DR-7s start with 4 digit numbers on through 5 digit numbers. One Sigma DR-7 owner stated I have an old Sigma DR-7 Guitar.sn 6860. ![]() Further, DR-7s with a four digit ink stamped label serial number and a zero fret strongly suggests a very early build date. Some early 70s Sigma guitar serial numbers started with 7 suggesting the 197 build date (e.g. XXXXXX possibly equates to a build year 1975.) It is widely assumed by owners and Sigma historians that this is correct, though C.F. Martin cannot, or will not confirm this.
