To match with the bridge stormy monday, I think you will need Tim to wind you a lower output P-90. I have neck P-90's with the Crawler and with a Warpig bridge and know that they can keep up with them with no problems!
The sound of a neck P-90 is really sweet, it sits there between a humbucker and a Fender single coil. It has a fatter tone, even though it is only a single coil.
