Hey ShadowEclipse,
I have been planning out the wiring for my 24" scale, no-truss rod, JM-trem thing. It'll have a humbucker in the bridge, a Mustang-style pickup in the neck, and a ceramic lipstick-style (in Strat/Mustang format) in the middle position. Now, I don't particularly care for middle pickups, but I've found I like those super-agressive ceramic coils sound really good in series with another pickup. The idea is to have a regular 3-position switch for the neck and bridge (neck - neck & bridge parallel - bridge) and an extra series two positions switch that would connect the mid pickup in series with whatever position the 3-way switch is in.
I also want a lower tone cap value when the series mode is on - going from something bassy to a more nasal, obnoxious quack.
Here's what I came up with:
(sorry for the crazy spaghettis all over the place)
Does this look sensible to you? Am I forgetting something important (I probably am)?
edit: To clarify, there would be no switch position combination where the middle pickup would be on its own. Its function would be strictly to function in series with the other two. so I guess the combinations would be:
(SERIES OFF)
-Neck
-Bridge/Neck parallel
-Bridge
(SERIES ON)
-Neck + Mid series
-Mid in series with Bridge & Neck parallel (now I'm quite curious to hear this one)
-Bridge + Mid series
The main slippy area I can see would be phase. Here's what looks logical to me:
-Bridge: Screws North up, clockwise ; Slugs South up, counter-clockwise
-Mid: South up, counter-clockwise
-Neck: North up, clockwise
This way, the neck + mid series position would be hum-cancelling, and the other two series positions as well as the bridge/neck parallel should be in phase. Those wouldn't be humcancelling, but that's inevitable anyway. The one thing that seriously gets my neurons overheating is trying to determine which lead from the mid pickup I should connect to which lug on the series switch. This one seems to be beyond my neurological powers
