I have an Andrew Schroetter 3/4 upright bass that I most likely will never use again. I am thinking of either selling it or trading it for an open back banjo, but I have no idea what it is worth. I tried searching for information on the bass, but couldn't find anything other than it looks like they are built in China now. This one is a model 2100 and built in 1985 in Germany. It has a bow and and a soft cover. If anyone can give me some idea what I should asking for it, I sure would appreciate it.
