# Two humbuckers with a three-way toggle, a push/pull split volume and a push/pull phase tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-push-pull-split-volume-push-pull-phase-tone Two humbuckers · Three-way toggle · Push/pull volume (splits both) · Push/pull tone (phase) Neck and bridge Seymour Duncan humbuckers on a three-way toggle with one 500k push/pull volume and one 500k push/pull tone with a .047 µF capacitor. The volume's push/pull splits both pickups by grounding each red–white link. The tone's push/pull reverses the neck pickup's black and green leads. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-push-pull-split-volume-push-pull-phase-tone.svg (back of controls) ## Parts and values - Neck Pickup: Seymour Duncan Neck Pickup; generic (Humbucker (four-conductor, Seymour Duncan colours)) - Bridge Pickup: Seymour Duncan Bridge Pickup; generic (Humbucker (four-conductor, Seymour Duncan colours)) - 3-Way Toggle: 3 Way Toggle; compatible example (Switchcraft 3-Way Toggle) - Volume 500k push/pull split: Volume 500k with Split Switch; 500k; compatible example (500k Push-Pull DPDT) - Tone 500k push/pull phase: Tone 500k with Phase Switch; 500k; compatible example (500k Push-Pull DPDT) - .047 cap: .047 cap; 47nF; compatible example (Orange Drop .047µF) - Output Jack: Output Jack; compatible example (Switchcraft \#11) - Bridge ground: Bridge ground wire; generic (Bridge ground wire) ## Specific to this wiring - The source titles the volume's push/pull as coil split and the tone's push/pull as phase. - Each pickup's red and white leads are soldered together onto a middle lug of the volume's push/pull: bridge on the left, neck on the right. - The two volume push/pull lugs nearest the pot are jumpered together and wired to the volume casing; the far row stays empty. - The neck black and green leads go through the tone's push/pull with an X cross-wire so pulling the tone reverses the neck; the neck bare ends on the tone casing. - The phase switch's hot out goes to the toggle's neck lug; the bridge black goes to the toggle's bridge lug. - The tone takes its signal from the volume's input lug; the .047 cap sits between the tone's middle lug and the tone casing. - The bridge ground wire ends on the volume casing; the jack sleeve ends on the tone casing, which is linked to the volume casing. - The toggle tags are not labelled in the source, so they are mapped by what each does. ## Connections 1. Neck green → Tone push/pull middle right (wire, green) 2. Neck bare → Tone casing (shield, bare) 3. Tone push/pull bottom left → Tone casing (case, black) 4. Bridge green → Volume casing (case, green) 5. Bridge bare → Volume casing (shield, bare) 6. Toggle frame → Volume casing (case, black) 7. Volume push/pull bottom left → Volume casing (case, black) 8. Volume right lug → Volume casing (case): Lug bent onto the casing. 9. .047 cap → Tone casing (case, black) 10. Volume casing → Tone casing (case, black) 11. Bridge ground wire → Volume casing (wire, black) 12. Tone casing → Jack sleeve (case, black) 13. Tone push/pull top left → Toggle neck lug (wire, black) 14. Bridge black → Toggle bridge lug (wire, black) 15. Toggle common → Volume left lug (input) (wire, black) 16. Neck white → Volume push/pull middle right (wire, white) 17. Neck red → Volume push/pull middle right (wire, red): Shares the lug with the neck white. 18. Neck black → Tone push/pull middle left (wire, black) 19. Bridge white → Volume push/pull middle left (wire, white) 20. Bridge red → Volume push/pull middle left (wire, red): Shares the lug with the bridge white. 21. Tone push/pull top left → Tone push/pull bottom right (wire, black): One leg of the X. 22. Tone push/pull top right → Tone push/pull bottom left (wire, black): The other leg of the X. 23. Volume push/pull bottom left → Volume push/pull bottom right (wire, black) 24. Volume middle lug → Jack tip (wire, black) 25. Volume left lug → Tone left lug (wire, black) 26. Tone middle lug → .047 cap (wire, black) ## What each position does - Neck, both knobs down: Neck Pickup (both coils). - Both, both knobs down: in phase: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. - Bridge, both knobs down: Bridge Pickup (both coils). - Neck, volume pulled (split), tone down: Neck Pickup (split to one coil). Source: Pulling the volume splits both pickups. - Both, volume pulled (both split), tone down: Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: Pulling the volume splits both pickups. - Bridge, volume pulled (split), tone down: Bridge Pickup (split to one coil). Source: Pulling the volume splits both pickups. - Neck, volume down, tone pulled (neck reversed): Neck Pickup (both coils). Source: Neck alone sounds the same when reversed. - Both, volume down, tone pulled: out of phase: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. Source: Neck reversed against the bridge. - Bridge, volume down, tone pulled: Bridge Pickup (both coils). Source: The bridge does not pass through the phase switch. - Neck, volume and tone pulled: Neck Pickup (split to one coil). Source: Neck split; reversed alone sounds the same. - Both, volume and tone pulled: split and out of phase: Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: Both split; neck reversed. - Bridge, volume and tone pulled: Bridge Pickup (split to one coil). Source: Bridge split; phase switch does not affect the bridge. - 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. ## Check before plugging in - In each toggle position the jack should read the selected pickup, or both in parallel in the middle. - Volume pulled: each red–white link should read continuity to ground. - Tone pulled in the middle position: the two pickups should be out of phase. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3G\_1VppSPL\_1TppPH, revision 1.
