# Two humbuckers, three-way blade, push/pull split volumes, push/pull phase and series tones Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-blade-push-pull-split-volumes-push-pull-phase-and-series-tones Two humbuckers · Three-way blade · Two 500k push/pull volumes (split) · Two 500k push/pull tones (phase, series) Neck and bridge Seymour Duncan humbuckers, each with its own 500k push/pull volume and 500k push/pull tone with a .047 cap, into a three-way blade. The volume push/pulls split their pickups, the bridge tone's push/pull reverses the bridge pickup's phase, and the neck tone's push/pull puts the two pickups in series. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-blade-push-pull-split-volumes-push-pull-phase-and-series-tones.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 blade: 3-Way Blade Switch; compatible example (CRL 3-Way Blade) - Neck volume 500k push/pull (split): Neck volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Bridge volume 500k push/pull (split): Bridge volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Bridge tone 500k push/pull (phase): Bridge tone 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Neck tone 500k push/pull (series): Neck tone 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Bridge tone .047 cap: .047 cap (bridge tone, drawn green); 47nF; compatible example (Orange Drop .047µF) - Neck tone .047 cap: .047 cap (neck tone, drawn green); 47nF; compatible example (Orange Drop .047µF) - Output jack: Output Jack; compatible example (Switchcraft \#11) - Bridge ground wire: ground wire from bridge; generic (Bridge ground wire) ## Specific to this wiring - Source title: '2 HUMBUCKERS \| 2 VOLUME push/pulls Coil Split', '2 TONES push/pulls phase and push/pull series parallel', '3 WAY BLADE'. - Source legend: 'Bridge volume: splits bridge pickup'; 'Neck volume: splits neck pickup'; 'Bridge tone: puts bridge & neck pickups out of phase with each other'; 'Neck tone: puts bridge & neck pickups in series together.' - Source note: 'in series-mode, the bridge pickup's controls do NOT work (this is normal, so don't freak out)'. - Each pickup's black runs to a volume push/pull or the volume's middle lug, not straight to the blade: the neck black goes to the neck volume's middle lug; the bridge black goes to the bridge volume push/pull middle-left lug and on to the bridge tone push/pull. Each volume's left lug feeds the blade. - The bridge pickup's red and white go together to the bridge volume push/pull bottom-left lug; the neck pickup's red and white go together to the neck volume push/pull middle-left lug, with the neck green on the lug below. - The bridge green goes to the bridge tone push/pull, not to a casing: it reaches ground through that switch. - Both tone push/pulls are drawn below their pots. The bridge tone's switch has an X cross-wire between its top and bottom rows; the neck tone's top two lugs are jumpered together. - Each volume's right lug is bent onto its casing. The tones' right lugs are left unconnected. - Plain wire crossings on the sheet carry no solder dot and are not joints; several wires cross with small hops. - Solder = location for ground (earth) connections. - The blade tags and push/pull lugs are not labelled in the source; they are mapped by what each does. ## Connections 1.
