I wonder can anybody help me. My 90's amp head seems to suddenly dropout with sound, crackles and sputters when i play it. It does this more if i turn the presence pot and other pots, but not as much. I have tried to clean the pots but cannot get right behind them. If i let it settle im happy with the tone but all of a sudden it will splutter and crackle again. This makes it impossible to chance it at a gig.Im gutted cos i love the tone and dont want to pat with it. Thanks for reading, hope someone can advise me.
