Get some Seymour Duncan 4 conductor humbuckers (Little '59 for neck and Hot Rails for bridge works amazing)...then get your volume and tone pots switched for DPDT switches so you can pull them up and push them down..one for each setting... Get the pups wired series/parallel...and have them wired to each of the pots..so for example..the tone pot controls the neck and the volume controls the bridge. Now you have 8 or 9 pup configurations.

BTW this is almost my setup exactly..except I have an SH-1 in the neck, which is almost the same thing as the Little '59.
