# Two humbuckers with a three-way toggle, a push/pull neck-split volume and a push/pull bridge-split tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-push-pull-split-neck-volume-push-pull-split-bridge-tone Two humbuckers · Three-way toggle · Push/pull volume (neck split) · Push/pull tone (bridge split) 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. Pulling the volume grounds the neck red–white link; pulling the tone grounds the bridge red–white link. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-three-way-toggle-push-pull-split-neck-volume-push-pull-split-bridge-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 neck split: Volume 500k push/pull (neck Coil Split); 500k; compatible example (500k Push-Pull DPDT) - Tone 500k push/pull bridge split: Tone 500k push/pull (bridge Coil Split); 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 for the neck and the tone's push/pull as coil split for the bridge. - Only one pole of each push/pull is used: the middle lug takes that pickup's red and white; the lug nearest the pot goes to that pot's casing. - Neck green and bare end on the volume casing; bridge green and bare end on the tone casing. - 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 and the toggle frame end 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. Volume push/pull nearest pot → Volume casing (case, black) 2. Neck green → Volume casing (case, green) 3. Neck bare → Volume casing (shield, bare) 4. Tone push/pull nearest pot → Tone casing (case, black) 5. Bridge green → Tone casing (case, green) 6. Bridge bare → Tone casing (shield, bare) 7. Toggle frame → 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. Neck black → 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 (wire, white) 17. Neck red → Volume push/pull middle (wire, red): Shares the lug with the neck white. 18. Bridge white → Tone push/pull middle (wire, white) 19. Bridge red → Tone push/pull middle (wire, red): Shares the lug with the bridge white. 20. Volume middle lug → Jack tip (wire, black) 21. Volume left lug → Tone left lug (wire, black) 22. Tone middle lug → .047 cap (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, volume pulled (neck split): Neck Pickup (split to one coil). Source: Pulling the volume splits the neck. - Both, volume pulled (neck split): Neck Pickup (split to one coil) and Bridge Pickup (both coils) in parallel. Source: Pulling the volume splits the neck. - Bridge, volume pulled: Bridge Pickup (both coils). Source: Volume split does not affect the bridge. - Neck, tone pulled: Neck Pickup (both coils). Source: Tone split does not affect the neck. - Both, tone pulled (bridge split): Neck Pickup (both coils) and Bridge Pickup (split to one coil) in parallel. Source: Pulling the tone splits the bridge. - Bridge, tone pulled (bridge split): Bridge Pickup (split to one coil). Source: Pulling the tone splits the bridge. - Neck, both pulled: Neck Pickup (split to one coil). Source: Neck split from the volume. - Both, both pulled: Neck Pickup (split to one coil) and Bridge Pickup (split to one coil) in parallel. Source: Neck split from the volume; bridge split from the tone. - Bridge, both pulled: Bridge Pickup (split to one coil). Source: Bridge split from the tone. - 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: the neck red–white link should read continuity to ground. - Tone pulled: the bridge red–white link should read continuity to ground. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3G\_1VppSPLn\_1TppSPLb, revision 1.
