# Three Strat Stack Plus pickups, 5-way blade, push/pull split volume and tone Canonical page: https://guitarwiring.app/wiring-diagrams/seymour-duncan/three-stacks-plus-five-way-push-pull-three-coil-split-volume-tone Three Strat Stack Plus · 5-way blade · Push/pull volume (3 coil split) · One tone Seymour Duncan sheet: three Strat Stack Plus pickups on a 5-way blade with a push/pull volume titled '3 coil split', one tone and a .047 cap. The sheet prints no pot values. Pull the knob and each selected stack drops to one coil: the middle red is grounded directly, the bridge and neck reds through the blade's second pole.

When push/pull is UP all pickups are true single coils. When push/pull is DOWN all pickups are hum-cancelling.' - Switch lead labels as printed: neck white, middle white, bridge white. - All black & bare wires get soldered here: the upper Solder spot on the volume casing, which also takes the ground wire to the bridge and the wire to the jack sleeve. - The bridge red and the neck red go to two lugs on the blade's second row, and a third lug on that row is wired to the push/pull's left middle lug. The middle red goes to the push/pull's right middle lug. - Near the push/pull the middle red and the bridge red cross without a hop and with no solder dot: the middle red bends down to the push/pull, the bridge red carries on to the blade. Elsewhere the neck red hops over the bridge red. - The two push/pull lugs nearest the pot are jumpered together and wired to the upper Solder spot; the two lugs furthest from the pot are empty. - The volume's outer lug is bent onto the casing under the lower Solder spot, which is wired to the tone's Solder spot. - The source does not number the blade's lugs or positions; the lugs are mapped by what they do (bridge, bridge + middle, middle, middle + neck, neck). The second pole's lugs are mapped so that the legend holds (see the terminal mapping and limits). - Legend: the grey Solder spot marks the location for ground (earth) connections. Jack: Tip (hot output); Sleeve (ground). The inner, circular portion of the jack. - The tone cap is printed '.047 cap'. ## Connections 1.

Middle drain → Volume casing (upper Solder spot) (shield, bare): Drawn gold. 6. Bridge black → Volume casing (upper Solder spot) (case, black) 7. Bridge drain → Volume casing (upper Solder spot) (shield, bare): Drawn gold. 8. Ground wire to bridge → Volume casing (upper Solder spot) (case, black) 9. Volume third lug → Volume casing (case): Lug bent onto the casing under the lower Solder spot. 10. .047 cap → Tone casing (Solder spot) (case) 11. Tone casing (Solder spot) → Volume casing (lower Solder spot) (case, black) 12. Volume casing (upper Solder spot) → Jack sleeve (wire, black) 13. Bridge white → Blade upper-left row, first lug (wire, white): Labelled 'bridge white'; the innermost white loop. 14. Middle white → Blade upper-left row, second lug (wire, white): Labelled 'middle white'. 15. Neck white → Blade upper-left row, third lug (wire, white): Labelled 'neck white'; the outer white loop. 16. Blade upper-left row, fourth lug → Volume first lug (wire, black): Loops under the blade. 17. Bridge red → Blade lower-right row, second lug (wire, red): Crosses the middle red near the push/pull without a hop; the neck red hops over it further on. 18. Neck red → Blade lower-right row, fourth lug (wire, red): Arcs over the other leads; this wire carries the hop where it crosses the bridge red. 19. Blade lower-right row, first lug → Push/pull left middle lug (wire, black): The black wire carries the hops where it crosses the pickup leads. 20. Middle red → Push/pull right middle lug (wire, red): Bends down to the lug where it crosses the bridge red. 21. Push/pull left lug nearest the pot → Push/pull right lug nearest the pot (wire, black): Short jumper. 22. Volume middle lug → Jack tip (wire, black): This wire carries the hops over the tone ground wire and the sleeve wire. 23. Volume first lug → Tone outer lug (wire, black) 24. Tone middle lug → .047 cap (wire, black) ## What each position does - Position 1 · push: bridge: Bridge Strat Stack Plus (both coils).

Source: Legend: when push/pull is DOWN all pickups are hum-cancelling. - Position 4 · pull: middle split + neck split: Neck Strat Stack Plus (split to one coil) and Middle Strat Stack Plus (split to one coil) in parallel. Source: Legend: when push/pull is UP all pickups are true single coils. - Position 5 · push: neck: Neck Strat Stack Plus (both coils). Source: Legend: when push/pull is DOWN all pickups are hum-cancelling. - Position 5 · pull: neck split: Neck Strat Stack Plus (split to one coil). Source: Legend: when push/pull is UP all pickups are true single coils. - The sheet prints no pot values; 250k stand-ins are used. - There is no three-throw push/pull: the '3 coil split' is one DPDT push/pull whose right pole grounds the middle red directly and whose left pole grounds the blade's second-pole common, which reaches the bridge red in positions 1-2 and the neck red in positions 4-5. - The blade's second-pole lugs are unlabelled and mapped by function: the reading that reproduces the legend (the lug next to that pole's common is live in positions 1-2, the last lug in positions 4-5). The published Everything Axe references read the same blade drawing's second pole the other way round; under that reading this sheet would ground the bridge and neck reds only in positions where those pickups are off, contradicting the legend. - The middle red and bridge red cross near the push/pull without a hop or solder dot; they are read as a crossing (the middle red bends down to the push/pull, the bridge red runs on to the blade). Read as a joint, both taps would be tied together and the legend's hum-cancelling DOWN setting would not hold. - The on-board component drawn across the bottom-coil pads of each Strat Stack Plus (no value printed) is not modelled. - Which shaft position grounds the push/pull's commons follows the usual push/pull behaviour (pulled joins the middle lugs to the lugs nearest the pot); the legend agrees that UP is the split setting. - Pickup resistance is not specified, so no numeric meter readings are given. ## Check before plugging in - Knob down: in each blade position the meter across the jack reads the full stack or stack pair selected. - Knob up: the middle red reads ground in every blade position. - Knob up, blade in position 1 or 2: the bridge red reads ground and the neck red reads open; in positions 4 and 5 it is the other way round. - With the knob down, the middle red and the bridge red must read open to each other. ## Source Tinkercaster's own drawing of the Seymour Duncan diagram 3STKplus\_5W\_1Vpp3SPL\_1T, revision 1.
