“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 volume's 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.
- 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 lug on its own tone pot, and that lug runs on to a common lug on the blade, so each tone only works on its own pickup.
- Each .047 cap sits between its tone's middle lug and that tone's casing.
- Three short jumpers join four blade lugs into one output that loops round to the volume's input lug.
- The neck green and bare end on the neck tone casing; the bridge green and bare end on the volume casing.
- The bridge ground wire ends on the neck tone casing; the jack sleeve ends on the bridge tone casing.
- Solder = 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.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Neck, knob down: full humbucker | Only the neck tone acts. | Neck pickup (both coils). |
| Neck + bridge, knob down: both humbuckers | Both tones act, each on its own pickup's lead. | Neck pickup (both coils) and Bridge pickup (both coils) in parallel. |
| Bridge, knob down: full humbucker | Only the bridge tone acts. | 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. |
| Bridge, knob pulled: single coil | The split switch 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).
- The simulator reports one tone control per position; the second tone is wired the same way on the other pickup.
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.
- Each tone only loads its own pickup's lead.
- 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.
