History Initial construction was in Japan by various manufacturers/factories 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 -7 are the most common early Sigma guitars until the late '70's. 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 (1970–83), to Korea (1984-93/94), and finally Taiwan (1993–2007). 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 Σ symbol (the Greek letter ), in mother of pearl. The sigma symbol is often described as a 'sideways M.' Interestingly, while playing a Sigma guitar the 'sideways M' becomes 'right side up' suggesting 'M' for.

By the mid 1970's (c1976) the headstock logo design changed to utilize a gold 'Martin style' decal stating 'Sigma ' in script with 'Est. 1970' underneath in a smaller block font. As is tradition in classical instruments, Sigma classical guitars do not have the, and one must rely on the inner label for identification. Labels and Brands Sigma's 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. Later one's (c1972 onward) had white labels that had gold lettering with a border, often reddish-brown or purple in color. 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.F. 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.)

Sigma Guitar Serial Number LookupSigma Guitars Serial Numbers YearThis 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-7's start with 4 digit numbers on through 5 digit numbers. One Sigma DR-7 owner stated 'I have an old Sigma DR-7 Guitar.s/n 6860. I bought it new in 1970.' Further, DR-7's with a four digit ink stamped label serial number and a zero fret strongly suggests a very early build date. Sigma Serial Number LookupSome early 70s Sigma guitar serial numbers started with 7* suggesting the 197* build date (e.g. 75XXXXXX 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. 'Sigma-Martin USA' guitars built in 1981 and 1982 had serial numbers 900,001 to 902,908. Just bought my first Sigma lens. While trying to register the warranty, I discovered that the serial number on bottom is one digit less than the serial number on the warranty card. The lens body's number has 7 digits but the card has 8 digits. The numbers are identical except for the last digit on the warranty card. Got an old Sigma-Mod 52sdr7 ser.12674. Serial number look up. Bought guitar only marking is serial number ( e.g. 680-2rg ms) any help. Dec 19, 2018 Hi folks, Can someone tell me how can I decode the serial number to production year for my new sigma lens? Canon has for example a table which says where and when the lens produced.

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. In 1980 the paper labels were discontinued and the inner back brace was 'branded.' With the move of production to Korea in 1984, paper labels, this time with a fancy border, were reinstated, although some early 1984 models still retained the back center brace stamping. Sigma identified their dreadnought and grand concert guitars as 'Second Generation' when the headstock design changed to utilize a gold decal stating 'Sigma Guitars' in script with 'Est.
