I have only room for three switches/pots/pup selector etc in my newly aquired Peavey Vandenberg...
But I like to have plenty of tonal options in a guitar, but don't want to do any wood chopping on this one, so I have been sitting down trying to work out a nice way to achieve that.
So with only 3 components for me to use I ended up with the 4pdt, for example Dimarzio EP1111. A on-on-on switch with 12 lugs instead of the 2pdt's 6. Give some more options...
So in this guitar with 2 humbuckers I will use:
A) 1 volume with a push-pull. The pushpull will only be active choosing series/parallel in middle position of the 2nd 4pdt. Otherwise it will not matter what position the pushpull has, it is, so to speak, out of the circuit.
B) 1 4pdt to choose series/split/parallel for both pickups at the same time.
C) 1 4pdt to select bridge/both/neck pickup. It will also use some lugs to achieve a few things besides choosing pup.
As you see I have only one volume and no tone, which is fine by me, but of course there's no problem to use more pots if you have room for that...
I am really a beginner of wiring diagrams, so there should be other, simpler ways to do what I do here. And I really hope I've got everything right, I've been checking a number of times, so I hope I didn't mess it up when doing this diagram in Photoshop, taken from the pen and paper diagram I wrote up earlier.
There should be no wires "hanging loose" on the +-side, no dead positions and everything that needs to be grounded should be... I hope!:smash:
I haven't soldered this yet so it's not tested in real life, I hope someone don't follow this and get pissed if it don't work out? I will try this very thing soon...
Important to know, is that I haven't considered magnet polarity and winding here, so one humbucker needs to swap some wires to have hum-cancelling and in phase. If this is done right, 10 of this 12 options should be in phase and humcancelling. 2 can not be, since they are coil split alone.
I am really not interested in out-of-phase, so for me, I think this is all I need.
PushPull is supposed to work as this DPDT on/on:
And the 4pdt should work as this 4pdt on/on/on type 2:
So, what options will I have here:
4pdt #1 position 1
4pdt #2, position 1: Bridge series
4pdt #2, position 2, P/P pushed: Bridge series (in series with) Neck series
4pdt #2, position 2, P/P pulled: Bridge series (in parallel with) Neck series
4pdt #2, position 3: Neck series
4pdt #1 position 2
4pdt #2, position 1: Bridge split
4pdt #2, position 2, P/P pushed: Bridge split (in series with) Neck split
4pdt #2, position 2, P/P pulled: Bridge split (in parallel with) Neck split
4pdt #2, position 3: Neck split
4pdt #1 position 3
4pdt #2, position 1: Bridge parallel
4pdt #2, position 2, P/P pushed: Bridge parallel (in series with) Neck parallel
4pdt #2, position 2, P/P pulled: Bridge parallel (in parallel with) Neck parallel
4pdt #2, position 3: Neck parallel
