Seymour Duncan wiring

Two humbuckers, three-way toggle, one volume and two push/pull coil-split tones

Two humbuckers · Three-way toggle · One volume · Two push/pull tones (each splits its own pickup)

Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull tone and .047 µF capacitor ahead of a three-way toggle, then one 500k master volume. Each tone's push/pull grounds its own pickup's red–white coil link, so pulling a tone knob splits that humbucker.

“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 title names the two tones as push/pull coil splits.
  • Each pickup's red and white leads are soldered together onto the middle bottom-row lug of its own tone's push/pull switch.
  • On each push/pull, the bottom-row lug nearest the pot is jumpered to that pot's casing; the other lugs stay empty.
  • Each pickup's black lead goes to the top lug of its own tone pot, and that lug continues to the toggle.
  • The neck green and bare and the toggle's frame lug end on the neck tone casing; the bridge green and bare, the bridge ground wire and the jack sleeve end on the bridge tone casing.
  • The pot casings are linked: neck tone to bridge tone, and bridge tone to volume.
  • The Solder spots mark the locations for ground (earth) connections.
  • The toggle tags and push/pull lugs are not labelled in the source, so they are mapped by what each does.

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.
  • The source does not say which knob position splits; this follows the usual push/pull behaviour (pulled joins the middle lug to the lug nearest the pot).
  • The simulator's position summary names one tone control only; each tone sits on its own pickup's lead ahead of the toggle, so in the middle position both tones act on the combined signal.

Before you solder

Check before plugging in

  • Both knobs down: in each toggle position the meter across the jack reads the selected humbucker, or both in parallel in the middle.
  • Pulling a tone knob drops the reading for its own pickup to roughly one coil's resistance.
  • With the volume at zero, tip and sleeve should read as a short in every position.

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.
