.. and what could I do about it. This Fender Jaguar, a workhorse in a Grunge Band, has undergone a bridge pickup swap. Originally it was equipped with two P90s (neck: 7.8K and bridge 8.25K). It's owner let me put in a Dimarzio Super Distortion DP209BK (13.2K) to enhance ...distortion. I set it up to be just a tad louder than the neck pickup. Both pickups sound fantastic on their own and they complement each other. But if I switch to the middle position there's an annoying drop of volume. I don't think the pickups are out of phase - it certainly doesn't sound oop. What went wrong? Any ideas for a cure?
