- acoustic guitars
Dates of manufacture:
This guitar is a Sigma by Martin which was produced to compete with the lower priced asian models.
D - Dreadnought
R - Rosewood
28 - Designed after the "classical" D - 28 Martin
Made in Japan 1977 until 1982 when production moved to Korea
The logo on the head actually says "Sigma by Martin Est. 1970"
There are many who flame and spam forums saying that they are fakes and not Martin, and nothing could be further from the truth. Is a Toyota Camry manufactured in the US, not a Toyota?
The later Sigmas manufactured in Taiwan were a little suspect as to quality.
