This is an active EMG style guitar tone circuit. The strange thing is I can hear the "wiper" of the tone potentiometer. It almost sounds like a dirty pot, but for sure it's not. It's not a crackling sound, it's a smooth "crrrrrrrrrrrr" sound when you turn the wiper. The control is brand new, and I have tried 3 others.
The wiper noise is still there when the guitar volume is down. There are other active circuits in the guitar.
Where should I start looking for an issue. Would a constant DC voltage on the pot make this type of sound? Is there any other way to "hear" the wiper of a pot?
