I stumbled upon an acoustic bass guitar that I would like to buy. It's an EKO and searching the internet I noticed it probably is an BA4:
It resembles the bass on this picture very closely. Only it doesn't have a piezo pick-up system. It's 100% acoustic.
Does anybody know how much this bass is worth? The current owner has asked me to do a bid, but I have no clue as to how much I should bid.
