Vintage Synth Repair

Scott thanks for the quick response.

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
