I have this cheapo pieces parts PJ that has Model PJ's on it. Last week I decided to go with a new set of strings that required a truss rod adjustment (D'addario balanced tension XL's 40-95 if anyone gives a rat's ass). Had to take off the pickguard, and accidentally yanked the hot wire of the J loose from the stacked volume pot it's wired to. Soldered it back to the middle lug of the correct pot and it works again, but a strange thing now happens when I use the volume knobs...when only one knob is on full and I turn the other knob up full from a lowered setting, it crackles at the point the pickup is turned up full. It also happens if I turn down one pickup when both are on full...as soon as I start to turn one down, it makes a crackling sound as soon as it reaches the point that it's not on full. Never did it before. Whut I did? EDIT: I should have made it clear...the crackling only happens at the point in the pot where the volumes are both on full, and it only happens once and then works normally.
