I am about 4 weeks into double bass ownership and it seems I need a different instrument. I have a 1967 Kay M-3, a 1/4 size instrument. It plays and sounds good but it's just too small, which should have been no surprise...but it was. I have no idea how much I should ask for it. It is in very good shape, said the luthier, and it needs nothing except a new bridge and strings; it is structurally sound and has only a few small dings. I have looked everywhere I can think of but I have only come across one of these basses for sale for $1,750. Ideally, I'd like to sell mine and use the money to buy a 3/4 size. I am looking for a ballpark figure so that I can be realistic when I sell it and have some idea what price range I should be looking for in a 3/4 instrument. Is the $1,750 figure realistic? I appreciate your help!
