# Two humbuckers with a three-way toggle, two push/pull split volumes and two tones Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-two-push-pull-split-volumes-two-tones Two humbuckers · Three-way toggle · Two push/pull volumes (one split each) · Two tones Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull volume and 500k tone with a .047 µF capacitor before a three-way toggle. Each volume's push/pull grounds that pickup's red–white coil link.

Neck green → Neck volume casing (case, green) 2. Neck bare → Neck volume casing (shield, bare) 3. Neck volume push/pull nearest pot → Neck volume casing (case, black): Short wire to the solder spot. 4. Neck volume right lug → Neck volume casing (case): Lug bent onto the casing. 5. Bridge green → Bridge volume casing (case, green) 6. Bridge bare → Bridge volume casing (shield, bare) 7. Bridge volume push/pull nearest pot → Bridge volume casing (case, black): Short wire to the solder spot. 8. Bridge volume right lug → Bridge volume casing (case): Lug bent onto the casing. 9. Toggle frame → Bridge volume casing (case, black) 10. Bridge volume casing → Bridge tone casing (case, black) 11. Bridge ground wire → Bridge tone casing (case, black) 12. Bridge tone casing → Jack sleeve (case, black) 13. Bridge tone casing → Neck tone casing (case, black): Hops over the tip wire. 14. Neck volume casing → Neck tone casing (case, black) 15. .047 cap (bridge) → Bridge tone casing (case, black) 16. .047 cap (neck) → Neck tone casing (case, black) 17. Neck volume middle lug → Toggle neck lug (wire, black) 18. Bridge volume middle lug → Toggle bridge lug (wire, black) 19. Toggle common → Jack tip (wire, black): The tone-to-tone ground wire hops over it. 20. Neck white → Neck volume push/pull middle (wire, white) 21. Neck red → Neck volume push/pull middle (wire, red): Shares the lug with the neck white. 22. Neck black → Neck volume left lug (input) (wire, black) 23. Bridge white → Bridge volume push/pull middle (wire, white) 24. Bridge red → Bridge volume push/pull middle (wire, red): Shares the lug with the bridge white. 25. Bridge black → Bridge volume left lug (input) (wire, black) 26. Bridge volume left lug → Bridge tone left lug (wire, black) 27. Bridge tone middle lug → .047 cap (bridge) (wire, black) 28. Neck volume left lug → Neck tone left lug (wire, black) 29. Neck tone middle lug → .047 cap (neck) (wire, black) ## What each position does - Neck, both knobs down: Neck pickup (both coils). - Both, both knobs down: Neck pickup (both coils) and Bridge pickup (both coils) in parallel. - Bridge, both knobs down: Bridge pickup (both coils). - Neck, neck volume pulled: Neck pickup (split to one coil). Source: Pulling a volume splits that pickup. - Both, neck volume pulled: Neck pickup (split to one coil) and Bridge pickup (both coils) in parallel. Source: Pulling a volume splits that pickup. - Bridge, neck volume pulled: Bridge pickup (both coils). Source: Pulling a volume splits that pickup. - Neck, bridge volume pulled: Neck pickup (both coils). Source: Pulling a volume splits that pickup. - Both, bridge volume pulled: Neck pickup (both coils) and Bridge pickup (split to one coil) in parallel. Source: Pulling a volume splits that pickup. - Bridge, bridge volume pulled: Bridge pickup (split to one coil). Source: Pulling a volume splits that pickup. - Neck, both pulled: Neck pickup (split to one coil). Source: Pulling a volume splits that pickup. - Both, both pulled: Neck pickup (split to one coil) and Bridge pickup (split to one coil) in parallel. Source: Pulling a volume splits that pickup. - Bridge, both pulled: Bridge 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 - Both volumes down: in each toggle position the jack reads the selected humbucker, or both in parallel in the middle. - Pulling a volume drops its own pickup to roughly one coil and leaves the other unchanged. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3G\_2VppSPL\_2T, revision 1.
