# Seymour Duncan PRS-type five-way rotary conversion

Canonical page: https://guitarwiring.app/wiring-guides/seymour-duncan/prs-five-way-rotary-wiring

See the five pickup combinations and why this conversion calls for a bridge magnet reversal.

Applies to: WD_PRS_5WR_Custom: a full conversion with a new rotary switch, not a universal PRS factory pinout or direct pickup-swap instruction.

## What the five positions select

Inside means the coils facing the gap between the pickups. Outside means the neck-side coil of the neck pickup and the bridge-side coil of the bridge pickup. Turning a pickup changes which screw or smooth-post row occupies that location.



Source position | Coils | Connection
--- | --- | ---
1 | Bridge humbucker | Both bridge coils
2 | Outside pair | Parallel
3 | Inside pair | Series
4 | Inside pair | Parallel
5 | Neck humbucker | Both neck coils

## Why the source calls for magnet reversal

The source requires the bridge magnet’s polarity to be reversed for its arrangement. Magnetic polarity and electrical lead polarity differ: swapping wires does not reverse a magnet. Rotating the entire pickup in its mounting ring is not the same operation.

The sheet describes removing the baseplate and turning the magnet. That is internal pickup work. Establish the required polarity and correct procedure for the exact pickup before attempting it; a pickup technician can help.



## A conversion, not a universal pinout

A rotary switch connects several contact banks as its shaft turns. The sheet requires a new five-position rotary and a full rewire. Its drawing does not provide universal terminal numbers.

Our illustration explains selected coils, not solder-lug locations. Match the exact rotary’s continuity map to the source before soldering. Do not transfer the drawing to a different wafer layout by resemblance.



## Check the complete sequence

Verify coils and series versus parallel in all five positions. Check magnetic and electrical relationships before claiming hum cancellation. The selection illustration is not an electrical simulation or a complete converted harness.
