My setup as of now is in my sig. The amp has just been rewired and resoldered and it had ran fine for about a month. Then I started to get this distortion in the background of the note whenever I played certain notes on the g or d strings. I didnt let it bother me as the drums in my band usually covered it up. Then I picked up my new Fender, plug into the passive slot and it sounds good. But now it really expresses the distortion alot worse. Ive taken it in after buying the Fender and the most recognized electronic around here didnt find anything wrong with the cab or head. Can any of you maybe point out this problem? I have no idea what so ever.
