Thank you so much Weirdy, a diagram with that combo would be awesome.
With the "bridge on" would that technically make it a double up on position 3? Not that it matters, I'm just trying to wrap my head around it all!
As seen in the photo above, the Humbucker has a red sheath to the wire, but inside it has a white hot wire, and bare wire strands.
The single coil has a black sheath, with again, a white hot wire, and bare wire strands.
Hopefully this makes sense for you.
Any extra questions, please let me know!
