Damn, people nowadays.. Sounds like the guy is full of crap..Probably One of those youngsters whose parents gave him everything he wanted, let him run over them, got a trophy for being on the losing team, ect, ect..Now the world has to put up with his psycho, spoiled brat B.S. Could the guy even play? Sounds like it might be the case since he obviously doesn't know a lot about guitars. Then he decided learning how was too much trouble and now wants to reneg on the deal? Tough sh*t IMO. Pull a bluff and tell him to back off on the harassment or you're going to contact your lawyer. If he calls it, go hire one..A lawyer will generally call or send a letter to tell them he's gonna litigate if they don't cease and desist for a modest fee. Usually the mere threat of an attorney will make someone like your problem go away! I hate trying to deal with cragslist, or rather some of the people on there. One can find some good deals on there (although that's getting harder it seems) but some of the asshats one encounters on there can be real works of bad art!
