# Two humbuckers, three-way blade, push/pull series/parallel volume and push/pull phase tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-blade-push-pull-series-parallel-volume-push-pull-phase-tone Two humbuckers · Three-way blade · 500k push/pull volume (series/parallel) · 500k push/pull tone (phase) Two Seymour Duncan humbuckers through a three-way blade to one 500k push/pull volume and one 500k push/pull tone with a .047 cap. Each humbucker's red and white leads are taped off. Pulling the volume puts the two pickups in series with each other; pulling the tone reverses the lower (bridge) pickup's phase.

Each humbucker stays a full humbucker; the series/parallel push/pull switches the two pickups against each other, not the coils inside one pickup. - The upper pickup's green goes to the volume push/pull middle-left lug instead of the casing. The volume push/pull's two lugs nearest the pot are jumpered together; its top-left lug goes to the volume casing. - The lower pickup's green and black go to the two middle lugs of the tone push/pull, whose top and bottom lugs are cross-wired in an X. Its top-right lug goes to the tone casing. - On the blade, the top two left lugs are jumpered, the second left lug is jumpered to the third right lug, and the bottom two right lugs are jumpered; the bottom-right lug is the output to the volume. - The bridge ground wire goes to the volume casing. The volume's right lug is bent onto the casing. The tone's third lug is left unconnected. - The source legend marks the grey 'Solder' spots as the location for ground (earth) connections. - Sleeve (ground): the inner, circular portion of the jack. Tip: hot output. - The pickups, the blade lugs and the push/pull lugs are not labelled in the source; the upper pickup is taken as the neck, and the switch tags are mapped by what each does. ## Connections 1. Neck green → Volume push/pull middle-left lug (wire, green) 2. Neck bare → Volume casing (shield, bare) 3. Bridge green → Tone push/pull middle-left lug (wire, green) 4. Bridge bare → Volume casing (shield, bare) 5. Volume push/pull top-left lug → Volume casing (case, black): Loops left over the neck bare lead. 6. Volume push/pull bottom-left lug → Volume push/pull bottom-right lug (wire, black): Jumper across the two lugs nearest the pot. 7. Volume right lug → Volume casing (case): Lug bent onto the casing. 8. .047 cap → Tone casing (case) 9. Volume casing → Tone casing (case, black): Hops over the wires it crosses. 10. Tone casing → Jack sleeve (wire, black) 11. Tone casing → Tone push/pull top-right lug (case, black) 12. Bridge ground wire → Volume casing (wire, black) 13. Neck black → Blade top-right lug (wire, black) 14. Volume push/pull top-right lug → Blade bottom-left lug (wire, black) 15. Blade top-left lug → Blade second left lug (wire, black): Jumper. 16. Blade second left lug → Blade third right lug (wire, black): Jumper. 17. Blade third right lug → Blade bottom-right lug (wire, black): Jumper. 18. Blade bottom-right lug → Volume left lug (wire, black) 19. Neck red → Neck white (insulated, red): Soldered together and taped off. 20. Bridge red → Bridge white (insulated, red): Soldered together and taped off. 21. Bridge black → Tone push/pull middle-right lug (wire, black): Hops over the volume-to-tone wire on the way. 22. Volume push/pull middle-right lug → Tone push/pull top-left lug (wire, black) 23. Volume middle lug → Jack tip (wire, black) 24. Volume left lug → Tone left lug (wire, black) 25. Tone middle lug → .047 cap (wire) 26. Tone push/pull top-left lug → Tone push/pull bottom-right lug (wire, black): One arm of the X; crosses the other arm without joining. 27. Tone push/pull top-right lug → Tone push/pull bottom-left lug (wire, black): Other arm of the X. ## What each position does - Neck, volume down, tone down: Neck pickup (both coils). - Middle, volume down, tone down: Neck pickup (both coils) and Bridge pickup (both coils) in parallel. - Bridge, volume down, tone down: Bridge pickup (both coils). - Neck, volume down, tone pulled (phase): Neck pickup (both coils). - Middle, volume down, tone pulled (phase): Neck pickup (both coils) and Bridge pickup (both coils) in parallel. Source: Tone pulled: the bridge pickup's phase is reversed. - Bridge, volume down, tone pulled (phase): Bridge pickup (both coils). - Neck, volume pulled (series), tone down: Neck pickup (both coils) and Bridge pickup (both coils) in series. Source: Volume pulled (series): the neck pickup's green feeds the bridge pickup, so both pickups play in series from the neck pickup's black. - Middle, volume pulled (series), tone down: Neck pickup (both coils) and Bridge pickup (both coils) in series. Source: Volume pulled (series): the neck pickup's green feeds the bridge pickup, so both pickups play in series from the neck pickup's black. - Bridge, volume pulled (series), tone down: No pickup reaches the output. Source: Volume pulled (series): the blade's bridge-side common (bottom-left lug) is left open, so the bridge position is silent. - Neck, volume pulled (series), tone pulled (phase): Neck pickup (both coils) and Bridge pickup (both coils) in series. Source: Volume pulled (series): the neck pickup's green feeds the bridge pickup, so both pickups play in series from the neck pickup's black. Tone pulled: the bridge pickup's phase is reversed. - Middle, volume pulled (series), tone pulled (phase): Neck pickup (both coils) and Bridge pickup (both coils) in series. Source: Volume pulled (series): the neck pickup's green feeds the bridge pickup, so both pickups play in series from the neck pickup's black. Tone pulled: the bridge pickup's phase is reversed. - Bridge, volume pulled (series), tone pulled (phase): No pickup reaches the output. Source: Volume pulled (series): the blade's bridge-side common (bottom-left lug) is left open, so the bridge position is silent. - 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. - The source does not say which knob position does what; this follows the usual push/pull behaviour (pulled joins the middle lugs to the lugs nearest the pot). ## Check before plugging in - Both knobs down: each blade position reads the selected humbucker, or both in parallel in the middle. - Pull the volume: the neck and middle positions read both humbuckers in series (roughly the sum of both); the bridge position is open. - Pull the tone with the blade in the middle: the two pickups play out of phase. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3B\_1VppSP\_1TppPH, revision 1.
