2 HB, 2 push/pulls, 3 way toggle. The push/pulls would be volume and tone.
The Volume push/pull would be series (down)/parallel (up) for the neck pickup.
The Tone push/pull would be series (down)/parallel (up) for the bridge pickup.
Now this is the thing...I have 2 sets of pickups...a Duncan set (APHn, CCb) and a Dimarzio set (Steve Morse), and I will probably try out both sets. I know the wiring codes are different for each company...so how would the diagram change?
