Are you using a guitar amplifier? If so, I'd suspect the pre-amp tubes if 
you don't have the amp cranked up very loudly. Turn on your amp and tap 
on each pre-amp tube (they're the little ones). If you hear a loud 
"thump" through your speakers, the tube is microphonic and should be 
replaced. Microphonic pre-amp tubes are very common (especially in this 
era of suckola pre-amp tubes).
