My grandma told me she wanted to give me the old upright bass she used to play on in the 50's and 60's because I'm now the only other musician in the family. She said she wants to get it appraised before she gives it to me. She's had a few appraisals done, but doesn't necessarily trust any of the people that have done them because apparently the prices varied by quite a lot. I understand that the value will depend on the condition, but I just need to know a ball-park range so that I can let her know what to expect, so that I can tell her what to expect and hopefully expedite this process and start learning how to play some bass. It's a Kay Jazz 3/4 bass made in 1942 that hasn't really been played since the early 70's.
