First thought was why have you let a guitarist plug into it?... :)

The first port of call, and the easiest one to try a fix out on, would be the 12AX7 valve running the preamp.


EDIT: Is this National Hartke Breakdown Week? This is the third one in three days!!!

Sounds like something loose in there then, perhaps taking it apart and putting it back together has wiggled 'something' back into the right position.
