I am doing cash/trade thing on local CL for an Ibanez 5 string and the thing offered in trade is a Bass made by a company called DeRosa. I have never heard of this name before. The bass itself is a viola bass, like the McCartney/Beatle bass, it looks ok and appears to be in good working order. I really just want to know what kind of value the thing has. He said he got it new for $250...so I'm guessing it's not worth much....but you never know, maybe its some old 60s relic or something...so I thought I would ask. any help will be greatly appreciated.
