The quality and richness of tone expected from USA Martin guitars, right here at a Japanese build price.
From 1980 through 1983, the end of Japanese production, the back centre brace is pressure stamped, or “branded” in a football shape stating Sigma Guitars/Made in Japan/For/C.F. Martin & Co. followed by an ink stamp of the model number, and prefixed by the serial number assigned to the instrument. (e.g. L-R as seen through the sound hole: Serial number, “Brand,” Model number.)
An interesting Vintage guitar magazine link on details of the Generations of Martin Sigma guitars.
