Out of phase, half-out of phase, power-out of phase

Do you use any of these?

Just to clarify what I mean by these terms:

- out of phase: two pickups of any kind wired in parallel, where the phase of one pickup is (electronically or magnetically) reversed.

- half out of phase: the same two pickups but the one wired reverse phase has a capacitor in series. Bill Lawrence used a 0.01uf in his schematic. The Jerry Donahue wiring is a variation of this with additional resistors in series. The schematics I have seen show two 6.2k resistors but since 6.2k is not a standard value this may be an error, and the correct value is 8.2k (maybe it is just me but reading big excel files I often mistake 6s for 8s and vice versa).

- power out of phase: two pickups of any kind in series instead of parallel, and one being reverse phased. First seen in Gibson's L6 and popularized by PRS in their first Customs. It is also part of the Brian May Red Special wiring.

Thanks and cheers

What I recently did to a two humbucker guitar (a Tele Deluxe partscaster equipped with a Bareknuckle set of True Grit bridge, Abraxas neck) with a normal 3-way toggle and two push-pulls is the following:

-Push-pull no. 1 selects whether the bridge coils are in series or in parallel.
-Push-pull no. 2 puts the neck pickup in phase or half out-of-phase with the bridge pickup (half-out-of phase meaning that in that setting there is a 0.015uf cap in series with the neck pickup. I tried 0.01uf first but that was too boomy).

So I get the following sounds out of the guitar:

- Toggle #1: a) bridge series (the "rock tone") or b) bridge parallel (the "country tone")
- Toggle #2: a) both in parallel in phase, bridge series, b) as before, bridge parallel, c) both in parallel out of phase, bridge series, d) as before, bridge parallel. All work well clean, with little or much gain.
- Toggle #3: a) neck normal, b) neck out of phase = neck with a bit less low end (since the cap is in series with it).

This should work well with any two DiMarzio humbuckers as well.
