Title: Wiring experts:Prs wiring
Post by: viking on April 22, 2007, 04:21:46 PM

My custom22 has a 5way rotary switch;i would like to have the 2 humbuckers together but the normal wiring don't give you that !How can i do it ? The rotary switch is a special Prs switch (pcb?).I really don't understand why they don't do it !I like the 5 combinations but i would like to hear my new Mules together ! :?

I can't answer your question, but a good place to start would be the PRS wiring diagram:

Somehow, you have to figure out what's happening circuit-wise, then re-wire it to give both humbuckers in parallel.

FWIW, the Mules in my Eggle (which is like a PRS but a bit lighter) sound great in the middle position.

If you look up the original PRS 5-way wiring you will find that it does give you both pickups in position 3.  You lose some of the other settings too though.

Thanks for the help !I really wonder why Prs did change the 3° position  ( in 1989),it's a good sound but i'd rather have the 2 humbuckers together...

If i understand correctly,the 3° position is the 4coils together(série),so it's the 2 humbuckers together !So...no problem! :D

Not since the early 90's.  The 5 positions are:

Bridge
Bridge and Neck Screw Coils Parallel
Bridge and Neck Screw Coils Series
Bridge and Neck Slug Coils Parallel
Neck

This doesn't give the 2 humbuckers, just a wide humbucker from the series setting in the middle postion.

That's what i had understood but ,since i wanted the 2 humbuckers together...,my guitar-tec finally told me the 3°=4coils/série  :x .How can you have those 2 humbuckers together?!!!!!! :?:  :?  :x                             PS:Phil,it seems you have most BNP,could you describe the difference between the Mule (i now have a set ) and Black Dog,Abraxas,Emerald and VH2 ?Would be nice  8) .

You have to use this wiring:

But you lose some of the other in-between positions.   Your tech has to rewire the switch itself for this.
