3 Pickup options with 4 way switch

[GrannyClanger]

Hmm, is this unavoidable then with a 4 way switch? Happy to just get a different switch and call it a day, guessing a 5 way would be better suited

It's not only the switch per se, but how you wire it. A super switch would be necessary, but you still have to wire it correctly.

And to clarify, series will be black to green wires between two SD humbuckers?

Yes.

[GuitarDoc]

Just for clarification, parallel would be both blacks together and both greens together.

I’ve taken some time to work through it, and I’ve figured it out


Not quite the original brief, but I think it might even be better. I’ve since strung her back up and she’s singing away. Hopefully someone somewhere will get something out of my needlessly specific project.

Glad you got this running. I've been a little under the weather, and forgot all about it.

[GuitarDoc]

You wired it according to your diagram in post 21?
You've got your guitar strung up and its working in all positions as expected?
Because I don't see that it will work like you want in all switch positions from the diagram that you posted.

Yep all working correctly. Tapping the poles with a screwdriver shows the correct pickups are active, and strung up positions 2 and 4 have a very pronounced volume jump.
There are no volume dips, phase issues or incorrectly activated pickups across any positions.
