Seymour Duncan sheet: single-coil-sized humbuckers in the neck and bridge and a single coil in the middle on a 5-way blade, with a push/pull volume that splits both humbuckers, one tone and a .047 cap. The sheet prints no pot values.

## Specific to this wiring

- Title: 1 SINGLE COIL SIZED HUMBUCKER \| 1 SINGLE COIL 1 SINGLE COIL SIZED HUMBUCKER 1 VOLUME push/pull coil split \| 1 TONE \| 5 WAY BLADE.
- The neck and bridge pickups are drawn as Seymour Duncan Research boards (pads Finish, R, W, Gnd, B, G, Start); their leads leave in a cable of black, red, white, green and bare.
- Neck, middle and bridge hot leads (neck black, middle white, bridge black) go to three lugs in one row of the blade; that row's bottom lug is the common, wired across to the top lug of the other row, and on from there to the volume's first lug.
- The neck red & white go together to the middle lug of one push/pull column and the bridge red & white to the middle lug of the other. The two lugs nearest the pot are jumpered together and wired to the upper Solder spot on the volume casing; the two lugs furthest from the pot are empty.
- Neck and bridge green and bare, and the middle black, go to the lower Solder spot on the volume casing, which also takes the ground wire to the bridge and the wire to the jack sleeve.
- The volume's outer lug is bent onto the casing under the lower Solder spot.
- The blade's other row is otherwise empty.
- The volume's first lug is wired to the tone's outer lug; the tone's middle lug carries the .047 cap to the tone casing, and the tone Solder spot is wired to the volume's.
- 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).
- 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'; no pot values are printed.

11. Tone casing (Solder spot) → Volume casing (Solder spot) (case, black): Black from the tone Solder spot to the volume Solder spot; it carries a hop over the white wire to the jack.
12. Neck black → Blade wired row, second lug (wire, black): Neck black (from the neck cable) arcs over the top of the blade to the wired row, second lug from the common.
13. Middle white → Blade wired row, third lug (wire, white): Middle white loops over the blade to the wired row, third lug from the common.

15. Blade wired row, bottom lug (common) → Blade opposite row, top lug (wire, white): White from the wired row common (bottom lug) runs along the blade to the opposite row's end lug (top).
16. Blade opposite row, top lug → Volume first lug (input) (wire, white): White from that opposite-row end lug down to the volume input lug.
17. Neck red → Push/pull neck-pair column, middle lug (wire, red): Neck red runs with its white from the neck cable over the top of the push/pull to the middle lug of one push/pull column.
18. Neck white → Push/pull neck-pair column, middle lug (wire, white): Neck white with its red to the same push/pull middle lug.
19. Bridge red → Push/pull bridge-pair column, middle lug (wire, red): Bridge red runs with its white from the bridge cable up to the middle lug of the other push/pull column.

21. Push/pull neck-pair column, lug nearest the pot → Push/pull bridge-pair column, lug nearest the pot (wire, black): Short black jumper between the two push/pull lugs nearest the pot.
22. Volume middle lug → Jack Tip (wire, white): White from the volume middle lug to the jack Tip (hot output).
23. Volume first lug (input) → Tone outer lug (wire, white): Wire from the volume input lug to the tone lug at the end nearest the volume.
24. Tone middle lug → .047 cap (wire, black): Tone middle lug to one leg of the .047 cap.

## What each position does

- Position 1 · push: bridge: Bridge single-coil-sized humbucker (both coils). Source: Knob down: both red & white pairs float, so each humbucker is full.
- Position 1 · pull: bridge split: Bridge single-coil-sized humbucker (split to one coil). Source: Knob up: the push/pull grounds both red & white pairs, splitting whichever humbucker is selected.
- Position 2 · push: bridge + middle: Middle single coil and Bridge single-coil-sized humbucker (both coils) in parallel. Source: Knob down: both red & white pairs float, so each humbucker is full.
- Position 2 · pull: bridge split + middle: Middle single coil and Bridge single-coil-sized humbucker (split to one coil) in parallel. Source: Knob up: the push/pull grounds both red & white pairs, splitting whichever humbucker is selected.
- Position 3 · push: middle: Middle single coil. Source: Knob down: both red & white pairs float, so each humbucker is full.
- Position 3 · pull: middle: Middle single coil. Source: Knob up: the push/pull grounds both red & white pairs, splitting whichever humbucker is selected.
- Position 4 · push: middle + neck: Neck single-coil-sized humbucker (both coils) and Middle single coil in parallel. Source: Knob down: both red & white pairs float, so each humbucker is full.
- Position 4 · pull: middle + neck split: Neck single-coil-sized humbucker (split to one coil) and Middle single coil in parallel. Source: Knob up: the push/pull grounds both red & white pairs, splitting whichever humbucker is selected.
- Position 5 · push: neck: Neck single-coil-sized humbucker (both coils). Source: Knob down: both red & white pairs float, so each humbucker is full.
- Position 5 · pull: neck split: Neck single-coil-sized humbucker (split to one coil). Source: Knob up: the push/pull grounds both red & white pairs, splitting whichever humbucker is selected.

- The sheet prints no pot values; 250k stand-ins are used.
- Which shaft position grounds the red & white pairs follows the usual push/pull behaviour (pulled joins the middle lugs to the lugs nearest the pot); the sheet does not say which way splits.
- The single-coil-sized humbuckers are 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

- Knob down: in each blade position the meter across the jack reads the full pickup or pickup pair selected.
- Knob up: both humbuckers' red & white read ground; positions 1 and 5 drop to one coil's reading.
