Can you use a 250K pot on one PUP with 500K on a second?

    I have snapped the shaft on one of my pots and need to replace it.

    The Guitar has 2 B500K's (one which needs replacing) and an A500K.

    Just wondering whether I can replace the forward pup pot with a 250K and get a warmer tone on one pup, whilst keeping the 500K's on the rear two?

    I'm in a similar situation...
    P-Bass with a 250k
    and Humbucker with 250k.

    Would changing the Humbucker's pot to a 500k brighten it up... Thats what I was hoping it would do as the Humbucker is quite dark at the moment... Leaving the P as a 250k.

    Go for it. From what I have read, Richard's Micawber is wired with a 500k on the neck humbucker and a 250 on the bridge. Should be no tear in the time-space continuum to wire this way and should brighten your sound up some.

    I would try it, if the sound is not to to your liking, try somthing else.

    I agree with Line6Man. In a standard passive setup, the pickups are all interconnected via the path that leads to the output jack. If you change one pot to a lower value, all the other pickups will "see" that lower resistance between signal & ground.

    No, it won't tear a hole in the universe to try it - you might even like it. But I don't believe you can darken (or brighten) just the one pickup without also affecting the other(s).
