Seymour Duncan wiring

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

Two humbuckers · Three-way toggle · Two push/pull volumes (each splits its pickup) · Push/pull master tone (phase)

Neck and bridge Seymour Duncan humbuckers on a three-way toggle with two 500k push/pull volumes and one 500k push/pull master tone with a .047 µF capacitor. Each volume grounds that pickup's red–white link when pulled. The tone's push/pull reverses the neck black and green leads before the neck volume. The master tone and jack tip take the toggle common.

“Example part” means any part with the same value and lugs will do; the source does not name a brand. “Generic” stands in for an unspecified pickup: check your own pickup's lead colours before you solder.

Specific to this wiring

  • The source titles each volume's push/pull as coil split and the master tone's push/pull as phase.
  • Each volume uses one push/pull pole: that pickup's red and white on the middle lug, the nearest-pot lug to the casing.
  • The neck black and green leads go through the tone's push/pull with an X cross-wire; the phase hot out feeds the neck volume input; the neck bare ends on the tone casing.
  • Volume middle lugs feed the toggle neck and bridge lugs; the toggle common feeds the master tone signal lug and the jack tip.
  • The .047 cap sits between the master tone's middle lug and the tone casing.
  • The toggle tags are not labelled in the source, so they are mapped by what each does.

In soldering order: grounds first, then the switch, the pickups and the signal path.

Checked with the Tinkercaster wiring engine against the switching the source describes.

  • 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.

Before you solder

Ticks are kept in this browser only, as a reminder. They are not a check of your joints. New to soldering? Read the soldering cheat sheet.

Check before plugging in

  • In each toggle 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.

Measure across the output jack with a multimeter on its resistance range. No exact readings are given where the source does not specify the pickups.
