MARTIN B-1 Acoustic Bass Guitar
I have owned this Bass Guitar for almost 10 years (a long time), its in excellent condition.
The neck is straight does not buzz that you would get from other Acoustic bass guitars and very easy to play on (the strings seat very close to the fret board)
Look for your self and do your own research but you cannot buy this kind by Martin anymore (new) and they are not easy to come across used.
The quality of sound is amazing, you’ll have to hear it for your self.
I’ve been the only owner of the Bass, I’m willing to work with pricing.
