1970s Sigma DM-3 Dreadnought Guitar

Overview: Martin imported most of their Sigma-branded guitars from Korea. This DM-3 is an all-ply, daily-driver sort-of guitar -- very practical, with a decent sound, and not fussy at all. It has made a good knockabout/play-anywhere guitar for its previous owner (who had an M1 pickup stuck in the soundhole, previously). I took this in trade and then set-about sprucing it up a bit.


Repairs included: I gave it a level/dress of the frets, cleaned it up, and set it up. It's playing spot-on and ready to serve.

Condition notes: It has some wear and tear in the finish -- light scratches, scuffs, and small dings here and there -- but is otherwise in good shape. The original adjustable saddle still works nicely (and intonates decently) and there are two added strap buttons at the heel and endpin area. The fretboard's finish (it's ebonized rosewood) shows a bit of wear.


It comes with: Sorry, no case.
