I wired my PJ different than most for the purposes of how it interacts with distortion. Three-way switch wired Neck/Series/Bridge. I have a 500k Volume knob for increased treble output and to give better range to my Tonestyler. The Volume push /pull I use to switch my Jazz pickup from series to parallel for its dual coil. I have a Stellartone Tonestyler as my only "Tone" knob. Generally I have an overdrive pedal set just on the edge of break up with my Jazz pickup solo in parallel. I can then switch just that pickup to series for a touch more output, which gives me more dirt. I can then use my pickup selector to select my neck pick up for me dirt. Finally I still have the Series option on my pickup selector for even more dirt. Then if I'm really being anal I can use my Tonestyler for a number of different resonant humps in the midrange to give me a wide variety of flavors in my distortion. Been very happy with this setup and my Dimarzio Model PJ pickups. Kinda want to have this available on all my instruments. Great addition to any passive bass.
