i got myself a set of new strings for my bass just recently. all was well but wen i tried to do a neck bend ala billy sheehan, the tunings all screwed up. it wasnt like this before, even wen i changed strings. i did pull n tighten the strings to let em sit in. now before i splashed some money or waste time doing a bass autopsy, can anyone suggest the possible reasons why my bass acted dis way? the patient is a yammy attitude limited 1.
