For a more gradual volume control try a 16mm J taper pot. Fender sells a 1M version with pcb mounting bracket. Chop the bracket off and you are good. This will effectively lengthen the volume pot travel at low volume settings but will then become more linear past 2 or 3 and just saturate. You may no...
