Re: P Rails, inner rails in series?
P-Rails in Triple Shots, 2V2T '50s wiring, with pull phase and pickups-in-series/parallel switch. Now what to do with the other 2 possible pull pots... And the Freeway Switch 6-way toggle?
Blower switch(es), maybe? Quick switch to bridge in series (or parallel, could wire it either way)... Maybe a switch from tone to spin-a-split for each pickup?
Like a BC Rich Bich or Mockingbird overflowing with controls, except with every control multi-function so it keeps a classic appearance aside from the pickups...
Then there's magnets. A8 for bridge railside, RCA5 for P-90? Maybe A9 for neck rail, A4 for P-90?
