Seymour Duncan wiring

Two humbuckers, three-way blade, push/pull split volumes, push/pull phase and series tones

Two humbuckers · Three-way blade · Two 500k push/pull volumes (split) · Two 500k push/pull tones (phase, series)

Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull volume and 500k push/pull tone with a .047 cap, into a three-way blade. The volume push/pulls split their pickups, the bridge tone's push/pull reverses the bridge pickup's phase, and the neck tone's push/pull puts the two pickups in series.

“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

  • Source title: '2 HUMBUCKERS | 2 VOLUME push/pulls Coil Split', '2 TONES push/pulls phase and push/pull series parallel', '3 WAY BLADE'.
  • Source legend: 'Bridge volume: splits bridge pickup'; 'Neck volume: splits neck pickup'; 'Bridge tone: puts bridge & neck pickups out of phase with each other'; 'Neck tone: puts bridge & neck pickups in series together.'
  • Source note: 'in series-mode, the bridge pickup's controls do NOT work (this is normal, so don't freak out)'.
  • Each pickup's black runs to a volume push/pull or the volume's middle lug, not straight to the blade: the neck black goes to the neck volume's middle lug; the bridge black goes to the bridge volume push/pull middle-left lug and on to the bridge tone push/pull. Each volume's left lug feeds the blade.
  • The bridge pickup's red and white go together to the bridge volume push/pull bottom-left lug; the neck pickup's red and white go together to the neck volume push/pull middle-left lug, with the neck green on the lug below.
  • The bridge green goes to the bridge tone push/pull, not to a casing: it reaches ground through that switch.
  • Both tone push/pulls are drawn below their pots. The bridge tone's switch has an X cross-wire between its top and bottom rows; the neck tone's top two lugs are jumpered together.
  • Each volume's right lug is bent onto its casing. The tones' right lugs are left unconnected.
  • Plain wire crossings on the sheet carry no solder dot and are not joints; several wires cross with small hops.
  • Solder = location for ground (earth) connections.
  • The blade tags and push/pull lugs are not labelled in the source; they are mapped by what each does.

Connections

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.
  • The source does not say which knob position does what; this follows the usual push/pull behaviour (pulled joins the middle lugs to the lugs nearest the pot), which matches the legend for every switch.

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

  • All knobs down: the blade gives neck, both in parallel, and bridge.
  • Pull the neck tone: the neck and middle blade positions read both humbuckers in series; the bridge position goes silent.
  • Pull the bridge tone with the blade in the middle: the pickups play out of phase.
  • Pull a volume: that pickup's reading drops to roughly one coil.

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.
