# Two mini-humbuckers with a three-way toggle, two volumes and two tones Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-mini-humbuckers-three-way-toggle-two-volumes-two-tones Two mini-humbuckers · Three-way toggle · Two volumes · Two tones Neck and bridge Seymour Duncan mini-humbuckers in the familiar two-volume, two-tone toggle layout. Each pickup has its own 500k volume and 500k tone with a .047 µF capacitor, and the three-way toggle picks neck, both or bridge. The red and white leads on each pickup are joined and taped off. Drawing: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-mini-humbuckers-three-way-toggle-two-volumes-two-tones.svg (back of controls) ## Parts and values - Neck mini-humbucker: Neck Pickup (mini-humbucker); generic (Humbucker (four-conductor, Seymour Duncan colours)) - Bridge mini-humbucker: Bridge Pickup (mini-humbucker); generic (Humbucker (four-conductor, Seymour Duncan colours)) - 3-way toggle: 3-Way Toggle; compatible example (Switchcraft 3-Way Toggle) - Bridge volume 500k: Bridge volume 500k; 500k; compatible example (CTS 500k Audio Pot) - Neck volume 500k: Neck volume 500k; 500k; compatible example (CTS 500k Audio Pot) - Bridge tone 500k: Bridge tone 500k; 500k; compatible example (CTS 500k Audio Pot) - Neck tone 500k: Neck tone 500k; 500k; compatible example (CTS 500k Audio Pot) - .047 cap (bridge): .047 cap on the bridge tone (drawn green); 47nF; compatible example (Orange Drop .047µF) - .047 cap (neck): .047 cap on the neck tone (drawn green); 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 - On each pickup, the red and white leads are joined and taped off. - Each pickup's green and bare leads go to its own volume casing; the black lead goes to that volume's left lug, which is also wired down to the matching tone's left lug. - The toggle frame lug goes to the bridge volume casing. Each volume casing is linked to its tone casing, and the two tone casings are linked. - The bridge ground wire and the jack sleeve both end on the bridge tone casing. - The source's inset 'For single-conductor humbuckers' says: the outer, braided shield-wire must be connected to ground (it may be soldered directly to the back of the volume pot, or to the ground terminal of the 3-way switch); the inner, black cloth wire is the hot output and connects to the 3-way switch. The main drawing shows four-conductor leads. - The source legend marks the grey 'Solder' spots as the location for ground (earth) connections. - The toggle tags are not labelled in the source, so they are mapped by what each does. ## Connections 1. Neck green → Neck volume casing (case, green) 2. Neck bare → Neck volume casing (shield, bare): Drawn grey beside the green. 3. Bridge green → Bridge volume casing (case, green): The sheet's 'Bare' and 'Green' labels sit beside these two leads; both end on the same Solder spot. 4. Bridge bare → Bridge volume casing (shield, bare): Drawn grey beside the green. 5. Bridge volume right lug → Bridge volume casing (case): Lug bent onto the lower Solder spot. 6. Bridge .047 cap → Bridge tone casing (case) 7. Bridge volume casing → Bridge tone casing (case, black) 8. Neck volume right lug → Neck volume casing (case): Lug bent onto the lower Solder spot. 9. Neck .047 cap → Neck tone casing (case) 10. Neck volume casing → Neck tone casing (case, black) 11. Bridge tone casing → Neck tone casing (case, black) 12. Toggle frame lug → Bridge volume casing (case, black) 13. Bridge tone casing → Jack sleeve (wire, black) 14. Bridge ground wire → Bridge tone casing (shield, black) 15. Bridge volume middle lug → Toggle bridge lug (wire, black) 16. Neck volume middle lug → Toggle neck lug (wire, black) 17. Toggle middle lug → Jack tip (wire, black) 18. Neck red → Neck white (insulated, red): Soldered together and taped off. 19. Neck black → Neck volume left lug (input) (wire, black) 20. Bridge red → Bridge white (insulated, red): Soldered together and taped off. 21. Bridge black → Bridge volume left lug (input) (wire, black) 22. Bridge volume left lug → Bridge tone left lug (wire, black) 23. Bridge tone middle lug → Bridge .047 cap (wire) 24. Neck volume left lug → Neck tone left lug (wire, black) 25. Neck tone middle lug → Neck .047 cap (wire) ## What each position does - Rhythm (neck): Neck mini-humbucker (both coils). Source: Neck pickup through the neck volume and tone. - Both: Neck mini-humbucker (both coils) and Bridge mini-humbucker (both coils) in parallel. Source: Neck and bridge together, each through its own volume and tone. - Treble (bridge): Bridge mini-humbucker (both coils). Source: Bridge pickup through the bridge volume and tone. - Hum cancelling and phase describe the generic pickup models, not a measurement of any specific Seymour Duncan mini-humbucker. - Pickup resistance is not specified, so no numeric meter readings are given. - The single-conductor alternative in the source inset is not simulated. ## Check before plugging in - In each toggle position, the meter across the jack should read the selected pickup, or both in parallel in the middle. - Each taped red–white joint should read open to ground. - In the neck or bridge position, turning the selected pickup's volume to zero should read tip to sleeve as a short. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2MH\_3G\_2V\_2T, revision 1.
