# Two humbuckers with a three-way blade, two push/pull split volumes and a push/pull phase tone

Two humbuckers · Three-way blade · Two push/pull volumes (split) · Push/pull master tone (phase)

Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull volume before a three-way blade, and a 500k master tone with a .047 µF capacitor. Each volume's push/pull splits that pickup. The tone's push/pull reverses the neck pickup's black and green leads before the neck volume.

## Specific to this wiring

- The source titles the volumes as push/pull coil split and the tone as push/pull phase.
- The neck black and green go through the tone's push/pull with an X cross-wire; the hot out feeds the neck volume's input lug.
- Each pickup's red and white leads are soldered together onto its own volume's push/pull middle lug.
- The master tone takes its signal from the blade output after the switch.
- Solder = location for ground (earth) connections.
- The blade tags are not labelled in the source, so they are mapped by what each does.

## What each position does

- Neck, all knobs down: Neck Pickup (both coils).
- Both, all knobs down: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel.
- Bridge, all knobs down: Bridge Pickup (both coils).
- Neck, neck split: Neck Pickup (split to one coil). Source: Pulling a volume splits that 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 blade position the jack reads the selected pickup, or both in parallel in the middle.
- Pulling a volume splits that pickup; pulling the tone in the middle position puts the pickups out of phase.
