# Two humbuckers with a three-way toggle, two push/pull split volumes and a push/pull phase master tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-two-push-pull-split-volumes-push-pull-phase-tone Two humbuckers · Three-way toggle · Two push/pull volumes (each splits its pickup) · Push/pull master tone (phase) Neck and bridge Seymour Duncan humbuckers on a three-way toggle with two 500k push/pull volumes and one 500k push/pull master tone with a .047 µF capacitor. Each volume grounds that pickup's red–white link when pulled. The tone's push/pull reverses the neck black and green leads before the neck volume. The master tone and jack tip take the toggle common.

Bridge green → Bridge volume casing (case, green) 7. Bridge bare → Bridge volume casing (shield, bare) 8. Bridge volume push/pull nearest pot → Bridge volume casing (case, black) 9. Bridge volume right lug → Bridge volume casing (case): Lug bent onto the casing. 10. Toggle frame → Neck volume casing (case, black) 11. .047 cap → Master tone casing (case, black) 12. Neck volume casing → Bridge volume casing (case, black) 13. Bridge volume casing → Master tone casing (case, black) 14. Bridge ground wire → Bridge volume casing (wire, black) 15. Bridge volume casing → Jack sleeve (case, black) 16. Neck volume middle lug → Toggle neck lug (wire, black) 17. Bridge volume middle lug → Toggle bridge lug (wire, black) 18. Toggle common → Master tone left lug (wire, black) 19. Neck white → Neck volume push/pull middle (wire, white) 20. Neck red → Neck volume push/pull middle (wire, red): Shares the lug with the neck white. 21. Neck black → Tone push/pull middle left (wire, black) 22. Bridge white → Bridge volume push/pull middle (wire, white) 23. Bridge red → Bridge volume push/pull middle (wire, red): Shares the lug with the bridge white. 24. Bridge black → Bridge volume left lug (input) (wire, black) 25. Tone push/pull top left → Neck volume left lug (input) (wire, black) 26. Tone push/pull top left → Tone push/pull bottom right (wire, black): One leg of the X. 27. Tone push/pull top right → Tone push/pull bottom left (wire, black): The other leg of the X. 28. Master tone left lug → Jack tip (wire, black) 29. Master tone middle lug → .047 cap (wire, black) ## What each position does - Neck, all knobs down: Neck Pickup (both coils). - Both, all knobs down: Neck Pickup (both coils) and Bridge Pickup (both coils) in parallel. - Bridge, all knobs down: Bridge Pickup (both coils). - Neck, neck split: Neck Pickup (split to one coil).

Source: Pulling a volume splits that pickup. - 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 reads the selected pickup, or both in parallel in the middle. - Pulling a volume splits that pickup; pulling the tone in the middle position puts the pickups out of phase. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3G\_2VppSPL\_1TppPH, revision 1.
