Hi, my uncle gave me a Martin Sigma acoustic a couple of years ago.
It is a dreadnaught style with serial # 801155.
It has an electric pick up with a single volume control but I'm not sure if this is original.
It has, "Sigma Guitars Est. 1970" at the top but no other defining marks.
He won this guitar in a raffle sometime in the late 70's or early 80's I'm pretty sure.
He used it as a spare guitar in his country band so it wasn't used a lot.
It is in great condition and sounds great.
Does anyone have a clue what model this could be?
