Long story short. I'm new to double bass and bought a very cheap Chinese Cremona SB-1 upright of Craigslist for $550. So far I have spend $900 on repairs, new strings, bridge, etc. The recent luthier I took it to, David Goad (David Goad Violins), said not to dump any more money into it and get a better bass. I am on the hunt for a better bass but am curious about what I should do with the one I have. It has obvious repairs and still needs work so I would feel badly about taking much money for the bass. On the other hand a friend is a music teacher at a school and she might welcome the instrument donation. What would you do? Thanks!
