Ok so I got a new guitar today (epi g400) and plugged it into my peavey aud 20 and it all of a sudden started to freak out after about a minute of playing. Why so? It can't be the guitar, it works fine in my other amp. BUT i used my other guitar on the peavey and it works fine. What is going on?

Um well it was playing clean then stopped working totally. Then started to work in a lower tone. Then it would go from one sound to the next. I'm not really sure how to describe the sounds, kind of like when you turn the treble all the way up on a car stereo and everything down.
