Here is a classic mod to a Les Paul that provides that signature Jimmy Page sound. All four control pots are push/pull control pots. They act as both volume/tone pots and switches. When all four switches are pushed in, you get the standard Les Paul control and sound. When they are pulled out, here’s what you get:
Bridge Volume: splits bridge pickup
Neck Volume: splits neck pickup
Bridge tone: puts bridge & neck pickups out of phase with each other
Neck tone: puts bridge & neck pickups in series together
This mod does not change the look of the Les Paul. The wiring is not very difficult if you have pretty good soldering skills. There are many versions of this on the web. Just Google “Jimmy Page Wiring” and you get many versions and even a few pre-wired harnesses. This version is from Seymour Duncan . I like it because it is easy to follow and does not require reading an electrical schematic.
I also like the version from Gibson. It simplifies keeping track of the lugs on the push/pull pots.
