S10 Excel guitar, NV112, Telonics 84PU & Vol pedal...Same kit for 20 years...very low hum developed; pedal on full, amp set for studio volume , as soon as I turn on the tone control (just on ) the hum is gone...?? Not audible when band is here...everything grounded .......Larry

I'd check for chassis ground on the tone pot. Remove pot, look at the mating surfaces, clean and sand lightly.
The cap might be dying, as well. They're cheap.
