## Specific to this wiring

- On each pickup, solder the red and white leads together and tape them off.
- The bridge ground and the jack sleeve both end on the tone casing, which is linked to the volume casing.
- The toggle tags are not labelled in the source, so they are mapped by what each does.

## What each position does

- Rhythm (neck): Neck Pickup (both coils). Source: Neck pickup.
- Both: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. Source: Neck and bridge together.
- Treble (bridge): Bridge Pickup (both coils). Source: Bridge pickup.

- Hum cancelling and phase describe the generic pickup models, not a measurement of any specific Seymour Duncan model.
- Pickup resistance is not specified, so no numeric meter readings are given.

## Check before plugging in

- In each toggle position, the meter across the jack should read the selected pickup, or both in parallel in the middle.
- Each taped red–white joint should read open to ground.
