Out of the box my P pickup was set funny, set low on one side and high on the other, on both parts of it creating sort of an arching shape. I lowered them, and set them straight but now everywhere I look the P pick up even in official Fender pictures have that arching offset thing going on, does it hurt my sound to straighten them out, are they supposed to be like that? Also, how low can you position the J pickup without ruining it's volume/tone?
