    Is this the XB200 ?...(Passive?) ~ One P-type, one J-type, 2 Volume, 2 Tone controls?

    If you're handy with a soldering iron, you should check all the ground connections -
    cold joints, etc. If re-flowing the grounds doesn't help, try this:
    Make sure there is continuous ground throughout the control cavity.
    There IS the concern Re "ground loops". If done properly though, you can
    eliminate the buzz. Normally, the "case" of a pot is used as a ground.
    This is fine if the pots are all secured to a metal plate. Not so good if
    they're secured through the (wood) body. If one of the wires from the J-pup
    is grounded to a pot, make sure that ground also gets to the ground of the
    output jack (along with all the other grounds). If need be, you can
    solder a wire from pot to pot to output jack. Also, make sure there is
    a good ground connection to the bridge. Without it, they act like a big antenna.

    I dropped-in a new pup on my cheapie Yamaha recently. It's pots are secured
    "through-the-wood". I noticed the pups were grounded to the pot's body,
    but that's where it ended. I ran a wire from pot to pot to bridge to jack => no more buzz.
