Pardon if this has been addressed, but I have had a similar problem with a handful of old Solid State amps: On the Clean channel, whenever I play a loud note (especially noticeable with bassier notes), there is a distortion/static sound I hear. The first Amp I noticed this was a Carvin SX-200 2x12 combo. I sold that to a shop and the owner said something about "Bad Output Capacitors". Later i got the same issue with a Fender M-80 Pro head. I used several different speaker cabs and got the same thing. Next came an old Kustom head. I am currently using a Trace Elliot Super Tramp Combo, and have started having the same issue. Is this an indication of capacitor failure? Just looking for a little guidance.
