Hey, ... neat thread.

My sigma "52SDM 2" has been through hell. It's been backpacked, camped, banged, burned, baked, dropped, and probably kicked a few times. This thing is a tank and fun to play. It has a full wooden tone with zero tin or ring. It really booms out nicely with banjos, fiddles, and mandos.

Obviously it's one of those 52S's Sterling mentioned. I imagine the 'D' is dreadnaught and the 'M' mohogany. Is the 'S' spruce? What about the the '2' ... it has a paper label, a black painted headstock face ("SigmaGuitars Est. 1970"), no internal Martin stamps, a solid top, and a 8612000524 serial number. I can't figure the sides or back. Great guitar.

Jack P.
