hey there chaps, got an annoying ground hum on my strat that won't go away! at some point i'll hopefully get around to doing the old star grounding or whatever it's called, but til then, any ideas about what to look for to help this? it's really damned loud, and of course goes away when i touch the metal. i'v redone the ground wire to the claw a few times and i'm sure that's got a good strong contact now... so what else could cause such a cacophony? cheers for any input!
