“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 the push/pull as a coil split switch that splits both pickups.
- Each pickup's red and white leads are soldered together onto a middle lug of the push/pull switch: bridge on the left, neck on the right. They are not taped off.
- The two push/pull lugs nearest the pot are jumpered together and wired to the volume casing; the two lugs furthest from the pot stay empty.
- Each pickup's black lead goes to a common lug on the blade; three short jumpers join four other lugs into one output that loops round to the volume's input lug.
- The bridge ground wire and the jack sleeve both end on the volume casing.
- The source legend marks the grey 'Solder' spots as the location for ground (earth) connections.
- The source does not number the blade positions; 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 split switch splits both pickups. | Neck Pickup (split to one coil). |
| Neck + bridge, knob pulled: both split | The split switch splits both pickups. | Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. |

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
- Knob down: in each blade position the meter across the jack reads the selected humbucker, or both in parallel in the middle.
- Knob up: each reading drops 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.
