I just bought a used crybaby bass wah-wah pedal (lots of fun!) but one thing that bugs me is that when I hit the switch to turn it off, it gets noticeably louder. So... I was thinking that I could add a 500k pot to the wire going from the switch to the output and bleed off some of the signal to the ground - essentially like a volume knob that is only in use when the switch is off. Is there any reason anyone can think of why this wouldn't work?
