Slight problem, the volume pedal in question is not a pot based one it seems to be more of a electro mechanical/inductor type one see pic.
So not as simple aslo if I can get it to do 100k could use it to control a wah or 500k and I can control a PWM pedal
Anymore input would be much appreciated

Hi seems to me as a photo type ie an l.d.r and a
simple lamp the ones I remember were between 18- 24 volts but other types
are/were around I suppose.usually only the lamps goes bad and occassionally a
bad ldr aswell.
