Re: pickup question
Gain = hotness. Hotter pups transfermore signal to the amp. Think of them as more sensitive, quicker responding, etc. All distortion/fuzz is caused by the amp not being able to handle that much signal. It could happen in the preamp, or the poweramp. Hot pups push a preamp tube over the edge, and a really pushed output tube causes output distortion. Preamp and output distrtion has different qualities. Keep the gain low and the output not too high and you should ge a clean sound. If not, turn the guitar volume down a bit. If none of that works, you need a different amp.
