How much feedback do you need to have on here to no longer be able to "look out for the little guy" or wherever the heck you are trying to go with that? I don't think you trying to imply that having a lot of feedback is indicative of anything more than having many successful transactions if going to get you any where.
You haven't really gone much into your efforts in trying to trade back. Other than the guy who has your bass did some mods to it, and he no longer thinks its a fair trade. Its not fair to sell a bass and not disclose issues, but man, if I buy a bass on here with the intention of modding it, I'm not waiting 45 days to do what I want to it.
How would you feel if he had dropped the bass that was previously yours, and cracked the neck in half. Would you still be so keen on trading back? I'm guessing not, because the value changed.
NEW RULE: you must take your own damn photos when selling gear.
What say you, noble moderators?
Like I said, lesson learned.
