Somebody in my local classifieds is trying to track down the person he sold a bass to years ago because he regrets it and wants to buy it back. Tragic.
I have lots of seller's remorse but especially for one bass - a Yamaha SB-35 - that I would most dearly love to buy back. I pester the guy I sold it to on a annual basis and he started off being polite but just ignores me now
