okay I have a p/j set up with standard config from the seymour duncan site. here is the problem. I picked it up to play and the e and a strings had a quaky sound with the p is soloed or when the jazz is turned all the way up. sounds pretty good if I roll back both the volume pots a tad. when the quake is there the e and a alway have only about a thrid of the vol of the others.
