Vintage early 1980's Martin Sigma DR-28.
These are excellent D-28 copies for the money, made during the heyday of Japanese "lawsuit" or import guitars, likely at the Tokai factory.
Has that classic D-28 tone that is robust and bright, with a low end that stays tight and crisp. Nice and loud, this is a great choice for when you don't want to take your real Martin out, or for gigging musicians looking for a great workhorse on a budget.
The neck is nice and straight still, playability is excellent in every condition.
Has signs of normal cosmetic wear common to a 40+ year old instrument. Overall a clean example that has been well cared for over the years.
Comes in a hard shell case
