Yup, I'm doing that as a part of this mod, too. Have an A500K push-pull pot coming along with the pickguard and mini-bucker. The coil-cut can be accomplished with a single extra connection through my "quick-connect" setup. Just solder a length of wire with one of the little male connectors to the two wires of a 4-conductor 'bucker that are pre-soldered & taped. The plug side of the quick connect is then wired to one of the middle lugs of the push-pull. You just connect the "pull" lug above it to ground, as shown in this humbucker coil-tap diagram on my web site:Originally Posted by Kazz
All you're really doing is putting a quick-connect in between the red-white wire solder joint and the push-pull switch. When you pull up on the pot knob, one coil is shorted to ground. The other continues to work, since you're just moving the ground connection point of that coil from one spot to another.
EDIT 7/12/10:
As mentioned two posts down from this one, the above method of shorting one of the two humbucker coils to ground was NOT useful in this case, due to the 4-way switch wiring to give the bridge and neck pickups in series at the fourth switch position. This wiring would cause the bridge pickup to be shorted to ground along with the one humbucker coil. Instead, the following alternative coil-cutting method was used, which shorts the other humbucker coil back on itself. The remaining coil stays "hot", passing its signal and the series bridge signal on to the volume pot. Diagram:
