“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 says the tone's push/pull split switch splits both pickups.
- Each pickup's red and white leads are soldered together onto one middle lug of the tone's switch, not taped off: bridge on the left column, neck on the right.
- The two switch lugs in the row nearest the pot are jumpered together and wired to the tone casing; the row furthest from the pot stays empty.
- Each volume's middle lug feeds a common lug on the blade; three short jumpers join four other lugs into one output that runs to the jack tip.
- The master tone takes its signal from the jack tip, after the blade.
- The bridge ground wire ends on the neck volume casing; the bridge volume casing, neck volume casing and tone casing are chained together, and the jack sleeve ends on the tone casing.
- Solder = location for ground (earth) connections.
- The source does not number the blade positions or its lugs; the lugs are mapped by what they do (neck, both, bridge).
Understand this wiring
- Seymour Duncan humbucker wire colors
See the pickup, recognise its two halves, and learn where each coloured wire goes.
- Seymour Duncan coil splitting explained
A humbucker has two coils. See how a switch lets you use just one of them.
- Reading Seymour Duncan push/pull switch diagrams
Turning the knob and pulling it do different jobs. See the actual part, then try its switch connections.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Neck, knob down: full humbucker | — | Neck pickup (both coils). |
| Neck + bridge, knob down: both humbuckers | — | Neck pickup (both coils) and Bridge pickup (both coils) in parallel. |
| Bridge, knob down: full humbucker | — | Bridge pickup (both coils). |
| Neck, knob pulled: single coil | The tone's push/pull splits both pickups. | Neck pickup (split to one coil). |
| Neck + bridge, knob pulled: both split | The tone's push/pull splits both pickups. | Neck pickup (split to one coil) and Bridge pickup (split to one coil) in parallel. |
| Bridge, knob pulled: single coil | The tone's push/pull splits both pickups. | Bridge pickup (split to one coil). |
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 lugs to the lugs nearest the pot).
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
- Tone knob down: in each blade position the meter across the jack reads the selected humbucker, or both in parallel in the middle.
- Tone knob up: each reading drops to roughly one coil's resistance.
- With a volume at zero, its pickup's black lead reads as a short to ground.
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.
