Seymour Duncan wiring

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

Two humbuckers · Three-way blade · 500k push/pull neck volume (series/parallel) · 500k push/pull bridge volume (phase) · 500k push/pull master tone (coil split)

Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull volume, into a three-way blade, with a 500k push/pull master tone and a .047 cap on the output. Pulling the neck volume puts the two pickups in series, pulling the bridge volume reverses the bridge pickup's phase, and pulling the tone splits both humbuckers.

“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/pull Series/Parallel, push/pull Phase', '1 TONE push/pull coil split'. The pots are labelled 'Neck Volume 500k series/parallel', 'Bridge Volume 500k phase' and 'Master Tone 500k push/pull'.
  • Source note: '**All pot casings MUST be grounded**'.
  • Both pickups' red and white leads go to the master tone's push/pull: the bridge pair to the middle-left lug, the neck pair to the middle-right lug. Its bottom-left lug runs to the bridge black at the bridge volume push/pull; its bottom-right lug runs to the neck green at the neck volume push/pull.
  • The bridge black and green go to the two middle lugs of the bridge volume's push/pull, whose top and bottom rows are cross-wired in an X; its bottom-left lug goes on to the bridge volume casing.
  • The neck green goes to the neck volume push/pull middle-right lug, not to a casing; the switch's top-right lug grounds it. The bottom two lugs are jumpered.
  • The bridge volume's input comes from the neck volume push/pull top-left lug, not straight from the pickup.
  • The master tone takes its signal from the blade output; its right lug is left unconnected. Each volume's right lug is bent onto its casing.
  • Solder = location for ground (earth) connections.
  • The blade is drawn without a label; its tags and the push/pull lugs are not labelled in the source, so 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 gives the titled function for every switch.
  • The silent bridge position with the series/parallel knob pulled follows from the drawn wiring; the sheet does not mention it.

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 volume: the neck and middle positions read both humbuckers in series; the bridge position goes silent.
  • Pull the bridge volume with the blade in the middle: the pickups play out of phase.
  • Pull the tone: each humbucker reads 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.
