hi all/my beloved big muff pi has developed a really loud background buzzing noise/it sounds like when you plug a lead into an amp and grab the other end/ive recently been running an alesis drum machine through it/is this likely to have fried it somehow?/also is this a repairable problem/ive tried using a boss noise suppressor on it and that makes virtually no difference/anyone got any suggestions?/regards//
just had the cover off/i see no loose wires or any other obvious faults/i have noticed though that the buzzing is at its loudest with the tone knob turned fully to the left and as you turn it clockwise the buzzing gets progressively quieter/so it may well be the tone knob/easy job to replace or am i just better off just chucking it in the bin and getting something else?…like a metal muff
