Not sure if this should go here or under the "effects" category, so here goes. I have a pair of P-Rails that I want to put in a PRS or LP. My understanding is that you can get three sounds per pickup: P-90, single-coil, and then humbucking, which is basically just both at the same time. For the people who have used these p'ups already, how have you wired it so that you have the option of getting all three sounds? (Plus I think there may be in phase/out of phase options too...) It seems like you could do it any number of ways; I wanted to see what was working best for people who are actually using them. I'd like to avoid adding switches to the guitar; don't want to do any drilling... I had thought about either the Duncan mounting rings with the small external switches, or maybe push-pull pots, if someone makes one with three positions rather than just two. What say you?
