I think the "PRS partial coil split" is a tonal improvement over splitting the coils of a humbucker by switching one coil completely off.
The two coils of a humbucker are connected in series with the end of the first coil's copper wire winding connected to the start of the second coil's copper wire winding. That junction is almost always the red and white wires of a 4 conductor pickup.
If you connect a switch to that junction so that when you engage the switch you connect that junction to ground, you'll shut the first coil OFF but leave the second coil ON. That's how a coil split switch works.
Basically what this Partial Split mod does is use a resistor connected to ground when the switch is engaged, instead of a wire.
Using a resistor prevents 100% of the output of that coil from going to ground and being lost. Some of the signal is "resisted" from leaving, and it stays in the audio signal.
The #1 coil remains partially ON and adds to the strength of the #2 coil.
I replaced the tone control in my '00 CE22 with this CTS 500K push/pull tone control that can split TWO humbuckers separately. The switch is actually TWO separate switches, one for each pickup.
I used a 1.1K resistor for the neck pickup and 2.2K for the bridge pickup.
This CE22 had already been modified by the original owner before I bought it from him. The original Dragon II pickups and rotary switch were already gone.
I removed the replacement pickups he'd put in it and installed a set of John Suhr SSV and SSH+ pickups.
The SSH+ is about as hot as a Dragon I Treble pickup, and if you're a Dragon lover it's a viable alternative to the Dragon I bridge pickup.
