# Two humbuckers, three-way toggle, two push/pull split volumes, master tone and mini-toggle phase Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-toggle-two-push-pull-split-volumes-tone-mini-toggle-phase Two humbuckers · Three-way toggle · Two push/pull volumes (coil split) · One master tone · ON/ON mini-toggle phase Neck and bridge Seymour Duncan humbuckers, each on its own 500k push/pull volume, through a three-way toggle to one 500k master tone with a .047 cap. Each volume's push/pull splits its own pickup, and an ON/ON mini-toggle reverses the neck pickup's hot and ground to put the two pickups out of phase. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-humbuckers-toggle-two-push-pull-split-volumes-tone-mini-toggle-phase.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 (unlabelled); compatible example (Switchcraft 3-Way Toggle) - Bridge volume 500k push/pull: Bridge Volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Neck volume 500k push/pull: Neck Volume 500k push/pull; 500k; compatible example (500k Push-Pull DPDT) - Output jack: Output Jack; compatible example (Switchcraft \#11) - Bridge ground: Bridge Ground Wire; generic (Bridge ground wire) - Master tone 500k: Master Tone 500k; 500k; compatible example (CTS 500k Audio Pot) - .047 cap: .047 cap (drawn green); 47nF; compatible example (Orange Drop .047µF) - Phase mini-toggle: Phase Switch (MINI-TOGGLE ON/ON); compatible example (DPDT Mini-Toggle) ## Specific to this wiring - The source labels the phase switch 'Up: out of phase' and 'Down: in phase'. - The neck black and green leads go to the two middle lugs of the phase switch; the top and bottom lugs are cross-jumpered in an X, the bottom-left lug goes to the neck volume casing and the bottom-right lug to the neck volume input. - The neck push/pull's split lug is wired to the phase switch lug that carries the neck green lead, not to ground. - On the bridge pickup the green and bare leads go straight to the bridge volume casing; a short wire joins the push/pull lug nearest the pot to the same casing. - On each pickup the red and white leads share the middle lug of the used push/pull row. - The toggle frame lug runs to the Master Tone casing; the neck and bridge volume casings are linked, and the bridge ground wire, jack sleeve and tone casing all end on the bridge volume casing. - 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 toggle and phase switch tags are not labelled in the source, so they are mapped by what each does. ## Connections 1. Neck green → Phase switch middle-left lug (wire, green) 2.

Source: Each volume's push/pull coil split splits its own 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. - The source does not say which knob position splits; this follows the usual push/pull behaviour (pulled joins the middle lug to the lug nearest the pot). - The phase mini-toggle is modelled with switchPosition: throw 2 (toward T3/T6) is in phase, throw 1 (toward T1/T4) reverses the neck pickup. Which lever direction reaches which throw is taken from the source's Up/Down legend, not from a lug label. ## Check before plugging in - Phase switch down, both knobs down: in each toggle position the meter across the jack reads the selected humbucker, or both in parallel in the middle. - Pull one knob: only that pickup's reading drops to roughly one coil's resistance. - Phase switch up: the neck-only reading is unchanged; in the middle position the two pickups are out of phase. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2H\_3G\_2VppSPL\_1T\_mtPH, revision 1.
