That keeps changing
At the moment it is my PRS Custom. I replaced the pickups many times and now arrived at a DiMarzio Dominion Bridge in the bridge and a DiMarzio Breed Neck in the neck. These are it for this guitar.
For years I hated the 5-way-rotary and finally replaced it with a DiMarzio EP1111 which I wired a la JP, i.e. bridge, inner coils in parallel and neck. Those were the tones I was mostly using. I never used the inner coils in series.
I then realized that I wanted the bridge humbucker in parallel to do AC/DC sounds but I did not want to lose the inner coils split sound. So I fitted two CTS 500k push pull pots. The one on the tone pot puts the bridge humbucker in parallel, which gives a Gretschy tone (not exactly alike but it fills the same sonic spot). The one on the volume control (1) splits the neck pickup to the inner coil and (2) when the tone pot is pulled it puts the bridge pickup to the inner coil only so that in the middle position I still have the inner coils in parallel. When the tone pot is not pulled, the volume pot pulled only splits the neck pickup.
That wiring gives me a total of 9 sounds, 6 of them humcancelling. 4 of them are important to me: bridge humbucker series, bridge humbucker parallel, inner coils parallel, neck humbucker series. I also now have both humbuckers in parallel and the neck pickup inner coil, which are both nice and useful and were not available with the original wiring.
Finally, the tone control operates as a bass contour knob, together with a 0.0022uf cap. I love this to remove the low end mud in the neck humbucker but it is also useful on the bridge pickup to add some more cut without going to parallel or split. I never used a standard tone control on that guitar as it is rather warm sounding.
The only two parts of the original wiring that are still in the guitar are the jack and the 180pf bright cap on the volume control
I still have all the original parts (HFS/VB, rotary, pots) just in case.
