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

Neck green → Neck tone casing (case, green) 2. Neck bare → Neck tone casing (shield, bare) 3. Neck tone push/pull nearest pot → Neck tone casing (case, black) 4. Neck volume right lug → Neck volume casing (case): Lug bent onto the casing. 5. .047 cap (neck) → Neck tone casing (case, black) 6. Bridge green → Bridge tone casing (case, green) 7. Bridge bare → Bridge tone casing (shield, bare) 8. Bridge tone push/pull nearest pot → Bridge tone casing (case, black) 9. Bridge volume right lug → Bridge volume casing (case): Lug bent onto the casing. 10. .047 cap (bridge) → Bridge tone casing (case, black) 11. Neck volume casing → Neck tone casing (case, black) 12. Bridge volume casing → Bridge tone casing (case, black) 13. Neck tone casing → Bridge tone casing (case, black) 14. Bridge ground wire → Bridge tone casing (wire, black) 15. Bridge tone casing → Jack sleeve (case, black) 16. Neck volume middle lug → Blade neck common (wire, black) 17. Bridge volume middle lug → Blade bridge common (wire, black) 18. Blade lug → Blade lug (wire, black) 19. Blade lug → Blade lug (wire, black) 20. Blade lug → Blade lug (wire, black) 21. Blade output → Jack tip (wire, black) 22. Neck white → Neck tone push/pull middle (wire, white) 23. Neck red → Neck tone push/pull middle (wire, red): Shares the lug with the neck white. 24. Neck black → Neck volume left lug (input) (wire, black) 25. Bridge white → Bridge tone push/pull middle (wire, white) 26. Bridge red → Bridge tone push/pull middle (wire, red): Shares the lug with the bridge white. 27. Bridge black → Bridge volume left lug (input) (wire, black) 28. Neck volume left lug → Neck tone left lug (wire, black) 29. Neck tone middle lug → .047 cap (neck) (wire, black) 30. Bridge volume left lug → Bridge tone left lug (wire, black) 31. Bridge tone middle lug → .047 cap (bridge) (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, first pulled: Neck Pickup (split to one coil). Source: Pulling a tone splits that pickup. - Both, first pulled: Neck Pickup (split to one coil) and Bridge Pickup (both coils) in parallel. Source: Pulling a tone splits that pickup. - Bridge, first pulled: Bridge Pickup (both coils). Source: Pulling a tone splits that pickup. - Neck, second pulled: Neck Pickup (both coils). Source: Pulling a tone splits that pickup. - Both, second pulled: Neck Pickup (both coils) and Bridge Pickup (split to one coil) in parallel. Source: Pulling a tone splits that pickup. - Bridge, second pulled: Bridge Pickup (split to one coil). Source: Pulling a tone splits that pickup. - Neck, both pulled: Neck Pickup (split to one coil). Source: Pulling a tone splits that pickup. - Both, both pulled: Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: Pulling a tone splits that pickup. - Bridge, both pulled: Bridge Pickup (split to one coil). Source: Pulling a tone 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 tones down: in each blade position the jack reads the selected humbucker, or both in parallel in the middle. - Pulling a tone drops its own pickup to roughly one coil and leaves the other unchanged. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3B\_2V\_2TppSPL, revision 1.
