# Two Strat Stack Plus pickups and a single-coil-sized humbucker, super 5-way blade, volume and tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/two-stacks-plus-sch-super-five-way-volume-tone Two Strat Stack Plus · Single-coil-sized humbucker (bridge) · 4-pole super 5-way · One volume · One tone Seymour Duncan sheet: Strat Stack Plus pickups in the neck and middle and a single-coil-sized humbucker in the bridge, on a 4-pole 5-way super switch with a 250k master volume, a 250k tone and a .022 cap. The two in-between positions split both selected pickups; the other three use one pickup whole.

The inner, circular portion of the jack. - The tone cap is printed '.022 cap'. ## Connections 1. Lower wafer lug 1 → Volume casing (lower Solder spot) (case, black): Drawn broken where it passes behind the pickup cables. 2. Lower wafer lug 12 → Volume casing (upper Solder spot) (case, black) 3. Neck black → Volume casing (upper Solder spot) (case, black) 4. Neck drain → Volume casing (upper Solder spot) (shield, bare): Drawn yellow. 5. Middle black → Volume casing (upper Solder spot) (case, black) 6. Middle drain → Volume casing (upper Solder spot) (shield, bare): Drawn yellow. 7. Bridge green → Volume casing (upper Solder spot) (case, green) 8. Bridge bare → Volume casing (upper Solder spot) (shield, bare): Drawn lilac beside the green. 9. Volume third lug → Volume casing (case): Lug bent onto the casing. 10. Volume casing (lower Solder spot) → Jack sleeve (wire, black) 11. .022 cap → Tone casing (Solder spot) (case) 12. Tone casing (Solder spot) → Volume casing (lower Solder spot) (case, black) 13. Bridge black → Upper wafer lug 7 (wire, black): Thin black lead leaving the bridge cable. 14. Upper wafer lug 7 → Upper wafer lug 8 (wire, black): Short jumper. 15. Middle white → Upper wafer lug 3 (wire, white) 16. Upper wafer lug 3 → Upper wafer lug 4 (wire, black): Short jumper. 17. Upper wafer lug 4 → Upper wafer lug 5 (wire, black): Short jumper. 18. Neck white → Upper wafer lug 10 (wire, white) 19. Upper wafer lug 10 → Upper wafer lug 11 (wire, black): Short jumper. 20. Upper wafer lug 1 → Upper wafer lug 12 (wire, black): Arcs over the top and down the left side of the switch. 21. Upper wafer lug 12 → Volume first lug (wire, black): Loops under the switch. 22. Middle red → Lower wafer lug 3 (wire, red) 23. Lower wafer lug 3 → Lower wafer lug 5 (wire, black): Jumper. 24. Bridge white → Lower wafer lug 8 (wire, white): With the bridge red ('bridge red & white'). 25. Bridge red → Lower wafer lug 8 (wire, red): With the bridge white ('bridge red & white'). 26. Neck red → Lower wafer lug 10 (wire, red) 27. Volume middle lug → Jack tip (wire, black): Hops over the ground wires on the way down. 28. Volume first lug → Tone outer lug (wire, black) 29. Tone middle lug → .022 cap (wire) ## What each position does - Bridge pickup full: Bridge single-coil-sized humbucker (both coils). Source: Bridge pickup full. - Bridge-split + middle-split: Middle Strat Stack Plus (split to one coil) and Bridge single-coil-sized humbucker (split to one coil) in parallel. Source: Bridge-split + middle-split (hum canceling). - Middle pickup full: Middle Strat Stack Plus (both coils). Source: Middle pickup full. - Middle-split + neck-split: Neck Strat Stack Plus (split to one coil) and Middle Strat Stack Plus (split to one coil) in parallel. Source: Middle-split + neck-split (hum canceling). - Neck pickup full: Neck Strat Stack Plus (both coils). Source: Neck pickup full. - The on-board component drawn across the bottom-coil pads of each Strat Stack Plus (no value printed) is not modelled. - The engine cannot confirm the hum cancelling the legend prints for the two split pairs; it reports those positions as unknown. - The single-coil-sized bridge humbucker is modelled by a generic four-conductor humbucker; hum cancelling and phase describe the generic models. - Pickup resistance is not specified, so no numeric meter readings are given. ## Check before plugging in - In each switch position, the meter across the jack should read the pickup or split pair the legend names. - In position 1 the bridge red & white lug should read open to ground; in position 2 it should read ground. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 2STK\_SCH\_S5W\_1V\_1T, revision 1.
