I am looking for some advice on an incident that is currently ongoing with a bass I sold to someone in the TB classifieds. Here is what happened. I posted for sale a MIM Fender Jazz bass that I recently received in a trade deal. The bass had a couple of mods like different pickups and the input jack had been moved from the control plate to the bottom. The mods were done nicely. The bass played nice and was in overall very good condition. The action was what I would consider medium The bass needed to be set up and I left that to the buyer. I tested the truss rod to make sure it was not broken or stuck and it moved freely in both directions. I packed the bass well and sent it FedEx to the buyer. He received it with no problems. I then received a PM from him saying the neck was warped very badly. The neck was not that way when I packed the bass and sent it to him. He told me he was going to have it checked by a tech and he would get back to me. I messaged him and told him to call me so we could discuss the problem. He has not called me at all. I offered him a refund if he sent the bass back to me. I then get another PM from him stating that the tech he took it to said the neck was no good. I again asked him to call me so we could discuss this issue. He also stated in the PM that he was going to order a new neck from Fender at a cost of $200. I again informed him if he was not happy with the bass to just box it up and send it back to me and I would happily refund his money and I also said I would pay for the return shipping. I am not sure what is going on here but something doesn't smell right. There was nothing wrong with the bass when I sent it to him. The price I sold it to him for was a fair average price for a nice MIM Fender Jazz. There was nothing special about this bass so why would someone spend more money on it instead of just sending it back to the seller. He would have more money in this bass than buying a new one at GC. There are several other nice MIM jazzes for sale in the TB classifieds. Something is just not adding up here. I have asked him numerous times to contact me or just send it back to me. I am not sure what this seller wants but I am starting to think he wants me to either buy him a new neck or at least pay some on a new one. I am not willing to do this as there was nothing wrong with the original that a good setup wouldn't have taken care of. I am beginning to think one of two things are going on here. First is he got the bass set up and is trying to scam me into paying for a new neck. Second either him or his tech ended up breaking the truss rod trying to adjust it. If he sends the bass back to me with a broken truss rod what should I do as it was not broken when I sent it out. Any suggestions on what to do about this situation. I hope I am not jumping the gun here but if I had bought a bass that was as messed up as he says this one was I would be on the phone or emailing the seller as soon as I got it unpacked. This seller has only 4 posts and no feedback so nothing to judge him by. I have sold or bought 10-12 items here on TB and don't want any negative feed back to affect me here in any way. The amount of money is what I would consider a small amount when buying stuff like this. In his last PM he said he is feeling like he got ripped off but once again no response from him when I told him to send the bass back. How the heck can you feel ripped off when someone offers you your money back if you would just send the item back.
