Thanks for the detailed replies.
I actually didn't mount the pickups myself, being not technically proficient with the soldering iron :P. I had a tech work on it to get the config that I wanted.
For positions 2/4 on the five-way switch I actually have the S1 combined with either split neck-side coil from the PafPro, or the Fred bridge-side coil. I also have a tone push-pull to have only the neck-side coil of the PafPro and
the bridge-side Fred on positions 1/5 (something like what Rich is doing).
I have a number of questions here, hopefully you can bear with me
Since both humbuckers have two coils each, how to I make sure that any of them are reversed polarity when combined with the S1? Having done that connection, would that mean that the two coils are out-of-phase or hum-cancelling? Can either one be reversed polarity? Is there any case that one coil from the humbucker coil and single coil combination will not be able ot hum-cancel?
Something out of hte topic, how different is a series connected humbucker compared to a parallel connected humbucker (in terms of wire connection and hum-cancelling? Are parallel connected humbucker technically the same as combining one coil in reverse polarity with a single coil?
Just trying to clear up my doubts here. Thanks
