| Bridge GroundSource: bridge ground wire | — | Bridge ground wireGeneric |
“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 bridge volume is printed as 250k push/pull coil split.
- The bridge humbucker red and white leads are soldered together onto the bridge volume push/pull middle-left lug, not taped off.
- The push/pull lug nearest the pot goes to the bridge volume casing.
- Legend: Solder = location for ground (earth) connections.
- The source does not number the switch positions; the lugs are mapped by what they do (neck, both, bridge).
- Jack legend: Tip (hot output); Sleeve (ground), the inner, circular portion of the jack.
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 | — | Neck pickup. |
| Neck + bridge, knob down | — | Neck pickup and Bridge pickup (both coils) in parallel. |
| Bridge, knob down | — | Bridge pickup (both coils). |
| Neck, knob pulled | — | Neck pickup. |
| Neck + bridge, knob pulled | — | Neck pickup and Bridge pickup (split to one coil) in parallel. |
| Bridge, knob pulled | — | 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.
- 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: each blade position reads the selected full pickup(s).
- Knob up: the humbucker(s) on the push/pull drop to roughly one coil.
- 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.
