so my ibanez RG7321 all of a sudden stopped putting out signal, just buzz like when you touch the end of the cable. what should i do? i guess it's probably a wire that got disconnected, my friend's dad knows how to solder things so if you can just tell me if theres a way to find out what got disconnected, that'd be great
Unscrew the output jack and carefully remove it. Any wire that is just hanging there; not attached to anything, is the one that came off of its contact. Solder it back on.
take cover off the back, and look for a loose wire
