For the third time, it's not my equipment, my amps, or the cables. Like I said, if I plug any other guitar into it, it works fine.
Hallowed is probably right, it's probably a shitty pot that went bad. It doesn't appear that any of the wires inside the guitar are disconnected or damaged in any way.
I had a pot go bad on an amp once, real pain in the ass to replace manually, being on a circuit board and all, but I'm sure its much easier to replace on a guitar.
It's just really weird how it happened. I plugged in, picked up the guitar, turned on the gear, struck a chord, THEN it just cut out for no apparent reason. I don't know much about what causes pots or anything to go bad suddenly, but I guess the only thing really to do is have the music shop test it out. I don't have extra pots or electronics for guitars lying around.
