Thanks Doc! I should have just explained my desired end result. I was a bit out of it yesterday and feeling more lucid today.
I have a guitar with the P-rails with triple shots installed. It is bottom routed and has holes for one pot, one LP style toggle and one mini toggle.
I'd like to set it up so I control the p-rails from the triple shots and be able to select whether the p-rails are in parallel or series when in the middle position.
I don't think I'd have much need for in-phase/out of phase. I really don't want to have to drill a larger hole, I'm afraid it might go badly since it has a gloss finish.
Any advice would be appreciated.
Thanks,
FTB
