My P-J washburn's J has quite a lor of hum...any ideas ons solving it?
Get a humbucker J pup.
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.
thanx a lot!
