Just in on trade! The vintage Japanese made Sigma DR-7 Dreadnought Acoustic Guitar is an iconic dreadnought held with a high esteem. Founded by Martin Guitars, Sigma quickly became known for their high quality construction, sound and playability.
Featuring a gorgeous Rosewood back and sides, a Spruce top and a Mah neck, the Sigma DR-7 Dreadnought guitar is made for tone.
The Rosewood fretboard add a beautiful overtone to the very comfortable C shaped, 25.5" scale neck that is easy and enjoyable to play.
Topped off with a dual-bound body, a bound headstock, an elegantly-simple soundhole rosette and a gloss finish.
We found information from one of the original ads for this guitar:
"Sigma guitars are made to the design and specifications of the world famous Martin organization of Nazareth, PA., U.S.A. And they are made in Japan by one of the world's foremost guitar makers who was specially appointed to meet the exacting standards of quality laid down by Martin.
This means with every Sigma you get the economy of production from Japan PLUS the backing and quality of C.F. Martin.
If you're in the market for a new acoustic guitar, do yourself a favour and get a Sigma!"
Guitar maker C.F. Martin & Co. created a line of inexpensive guitars in 1970 to compete with the increasing number of imported guitars from Japan and elsewhere. The result was Sigma Guitars.
The Sigma line was discontinued by C.F. Martin & Co. in 2007.
Sigma guitars made in Japan from 1970 through 1983:
The early 70s models (1970 -1975) can be distinguished by a more squared peghead, shaped similarly to that of a "spatula." The logo consisting of a gold decal with the single word in block lettering SIGMA surmounted with the Σ symbol (the Greek letter sigma), in mother of pearl. The sigma symbol is often described as a "sideways M."
While retaining the same early logo for several more years (c1975/76) the peghead itself began to take on a more tapered shape by 1972.
