AMP WIZARDS My practice amp is showing signs of stress. The signal breaks up as it is processed by the amp. It seems to be sensitive to attack(volume) and specific pitch. Specifically G in any octave. At first I thought it was the speaker, but have used the amp on another cab and got the same results. It is a not a valuable amp and I am wondering if it is worth fixing. I am guessing there is a short in the circuit board somewhere? How hard is that to find and fix if that is the case? It is a Carvin 150 watt pro. Any Ideas what could be causing this?
