Hi! :D
I just received my (awesome) Bare Knuckle Pickups: a Riff Raff neck, and a Cold Sweat bridge for my ESP Ecplise II.
For them, I developed my own wiring recipe, for maximal versatility, and cancelling hum as soon as 2 coils are active. Single/Parallel, coil splitting, phase inversion: with three switches (+ the 3-way toggle) get them all, with less get what you want! 8)
You can find a sound demo and all the explainations here:
