The Jimmy Page wiring is a fairly complicated switching system made famous by Jimmy Page and was later used in Gibson’s line of Jimmy Page Les Pauls. It uses four DPDT switches and incorporates coil taps for both pick ups as well as a phase switch on the bridge humbucker and a series/parallel switch for combining both humbuckers in series and parallel for a total of twenty one different pick up wiring possibilities. The schematic is available from Gibson’s website.
