Why is it that the pole pieces on stock MIM jazz (4 string) pickups never line up properly with every string (particularly the E string)? You'd think they would fix that on an instrument that is produced in such tremendous quantities. I guess the more important part of my question is whether or not there is a set of replacement pickups that correct this problem, preferably without any routing. Alternately, what's the easiest way to alter the bridge pickup cavity if you don't own a router and still want a neat job? An answer to either of these questions would set me inn the right direction, thanks.
