Do pots make much difference to the sound, as I have bought some, what seem to be good quality pots that are non Fender. The problem I am getting is a slightly overpowering harshness when the volume is above 5, and if I hit the strings quite hard I get a harsh sound. The do not seem to like distortion effects. This is the second time I have had this problem as I recently bought some CS 54's and they were worse. Could it be the kind of pickups that I am buying? I am looking for a John Fruishante/ Floyd kind of sound.
