1988 Sigma by Martin SDM-18. Can send more pics. Trades considered. Solid spruce top with scalloped bracing and ebony fingerboard. Sounds wonderful. It has a V- shaped neck very much like Martin guitars. It has a few finish flaws and a hairline crack near the soundhole on the top that are hard to detect and do not affect sound or playability. This is how it came from the factory as a 2nd. Very nice sounding guitar. Will consider trades for pedals or electric guitars.
