I just finshed dropping in a Duncan JB in the bridge poistion of my Ibanez RG. I noticed that the high e string and the b string are not centered over the pole piece in the pup, but only at the bridge pup. They seem to be ok at the neck pup, ok at the middle, and seem to "stray off course" at the bridge pup. The high e is worse than the b string. What's the deal? I can tell that there's a volume drop when I hit the high e with the bridge pup engaged. Is this a neck issue? The pup spacing seems to be OK. The low e is centered over the pole and the trem looks straight.
