Ok, here's my problem:
I replaced my stock peavey jazz bass pickups with EMG selects. I was told by several people that the new pickups were humbuckers, so I should use 500k pots. As the old ones were 250's, I ordered three from Stewmac, along with a new capacitor. Tonight, a friend and I wired it all up. Problem is, unless both volume pots are all the way up, I get a nasty buzz. If the volumes are up, I can play with the tone. If I mess with the volumes, I have to turn the highs out of the tone to get rid of the buzz. Also, the buzz would change as a moved the guitar around. Softer then louder.
We followed the diagram supplied with the pickups, and can't see any problems with how things were soldered, but obviously there is one. Could we have damaged a pot by getting it too hot? Also, the solder had a hard time sticking to the pot. He scratched the surface to expose bare metal on each.
Any ideas?
