I used the two old volume pots for the pre-existing pups, and one of the old tone pots for the new pup. I would imagine that the volume pots were 250k and the tone pot was 500k, and that is why I had the issues. when I turned the new pup pup pot down just a little, it shut the pup off entirely, and the original two pups got much louder. I just ordered 3 250k pots for the volumes and one 500k for the tone, and will hook it up with those when they come. That should solve the problem, if not.....?
