Alright. I am going to building a guitar in woodshop in the next month or two and it is going to be very similar to a PRS. I plan on ordering the PRS wiring kit from stewmac and looked up the wiring diagram on Seymour Duncan's site. It says that I need to reverse the magnet in the bridge pickup to acheive accurate switching. Can anyone tell me how hard that would be to do? It doesn't sound that hard, but I know little about pickups so I wouldn't want to screw up a pup just trying to reverse the magnet.

This is the diagram if you want to see it.

Thanks for the help guys.

You can flip the magnet on one of the pickups.
It's also very easy to break the coil wires when you do this.
When you flip the magnet on a HB, that changes the polarity of the signal.
The diagram on the SD site, corrects for this
by using the Green as hot and the Black as ground
on the pickup with the flipped magnet.

Personally, I think flipping magnets is a stupid, unnecessary idea.

Why flip a magnet in the first place?
Let's look at what they were trying to accomplish:

1 - Pair up 2 inner coils or 2 outer coils in 3 of the selections.

2 - Maintain hum-canceling.

3 - Typical arrangement of HBs is with
  • the Neck HB having the screw coil toward the neck
  • the Bridge HB having the screw coils toward the neck


4 - This means that
  • when the inner coils are selected we have 2 slug coils.
  • when the outer coils are selected we have 2 screw coils.
  • neither of these will hum-cancel


5 - One solution: Flip the magnet on one of the pickups and change it's wiring.


A better solution:

Turn the Bridge HB so the screw coil is toward the neck.

OR

Turn the Neck HB so the screw coil is toward the bridge.

Doing either of those will cause the inner and outer pairs to be 1 screw coil and 1 slug coil.
Those will hum-cancel.
No flipping necessary.
Just a few changes to the wiring.

Also, rotary switches are clumsy and slow.
Lever switches are faster.
Schaller has a switch that does the PRS combinations.
It's much simpler to wire and use.
Megaswitch model P.
You might want to consider using that, instead of a rotary.

Wow. Thanks for such a godly answer. I think I will just flip the bridge pickups. The only problem is that I was going to get zebra colorerd buckers, but if I have to, I can just go with covered ones. I just personally like the zebra pups with the cherry sunburst look a lot.
