Anyone know what the small capacitor on this volume pot is for?

    What is the purpose of the smaller capacitor?

    Thanks

  2. Treble bleed mod.
     
  3. what line6man said: treble bleed. It's used so that when you turn the volume down the sound does not get muddier.

    Shouldn't there also be a resistor?
     
  5. No, most people don't find it necessary.

    A PRS guitar I used to have was wired that way for volume control not affecting tone. Worked great and seemed to give wider useable range to the tone control then most guitars.

    I have an old Fury that has the bleed cap. It is an axial type that looks kinda like a fat resistor.

    This is only for active pups, yeah?
     
  9. The only difference between active and passive pickups is the nature of the output impedance. Doesn't matter what feeds into the volume pot, it always does the same thing. That being said, the actual effect is subject to change with the signal feeding through it. Treble loss is not usually as big of an issue with a low impedance buffered signal.

    IOW, it's usually for passive pups and passive wiring, not an active system.
