Alrighty then! I have been posting about an old Hondo P bass copy that I have been modding. My last problem was with hum and buzz, which magically disappeared. One problem down. There is a Dimarzio p pick up in neck position and I just installed a Peavey super ferrite in bridge. All is well, both pu's work. By themselves they sound nice. But when I flip the switch to activate both, I get a reall drop in volume on the E and A strings. D and G sound as they should,but E&A almost sound out of phase.Kinda hollow. Im pretty sure I wired everything right as the pu's sound fine when played one at a time. Could this be due to the position of the pole pieces for E & A strings on the p pickup being further away from the neck pickup,and causing a phase issue? Like I said earlier D & G strings sound good. Any thoughts/remedies on this one?????
