## Parts and values

- Neck stack: Neck stack; generic (Humbucker (four-conductor, Seymour Duncan colours))
- Middle stack: Middle stack; generic (Humbucker (four-conductor, Seymour Duncan colours))
- Bridge stack: Bridge stack; generic (Humbucker (four-conductor, Seymour Duncan colours))
- 5-Way Switch: 5-Way Switch; compatible example (Oak Grigsby 5-Way)
- Volume 250k: Volume 250k; 250k; compatible example (CTS 250k Audio Pot)
- Output Jack: Output Jack; compatible example (Switchcraft \#11)
- Ground wire to bridge: Ground wire to bridge; generic (Bridge ground wire)

## Specific to this wiring

- Stack-plus pickups use the same generic four-conductor humbucker stand-in as three-stack siblings; hum-cancelling construction is not modelled beyond the transcribed lug map.

## Connections

1. Neck stack gnd → Volume 250k casing (wire, green)
2. Neck stack bare → Volume 250k casing (wire, bare)
3. Middle stack gnd → Volume 250k casing (wire, green)
4. Middle stack bare → Volume 250k casing (wire, bare)
5. Bridge stack gnd → Volume 250k casing (wire, green)
6. Bridge stack bare → Volume 250k casing (wire, bare)
7. Ground wire to bridge ground → Volume 250k casing (wire, black)
8. Volume 250k lug1 → Volume 250k casing (wire, ground)
9. Volume 250k casing → Output Jack sleeve (wire, black)
10. Bridge stack hot → 5-Way Switch T3 (wire, black)
11. Middle stack hot → 5-Way Switch T1 (wire, black)
12. Neck stack hot → 5-Way Switch T2 (wire, black)
13. 5-Way Switch T4 → 5-Way Switch T8 (wire, black)
14. 5-Way Switch T8 → Volume 250k lug3 (wire, black)
15. Neck stack black → Neck stack white (wire, red)
16. Middle stack black → Middle stack white (wire, red)
17. Bridge stack black → Bridge stack white (wire, red)
18. Volume 250k lug2 → Output Jack tip (wire, black)

## What each position does

- Bridge: Bridge stack (both coils). Source: Engine reading of the transcribed board.
- Bridge + middle: Middle stack (both coils) and Bridge stack (both coils) in parallel. Source: Engine reading of the transcribed board.
- Middle: Middle stack (both coils). Source: Engine reading of the transcribed board.
- Middle + neck: Neck stack (both coils) and Middle stack (both coils) in parallel. Source: Engine reading of the transcribed board.
- Neck: Neck stack (both coils). Source: Engine reading of the transcribed board.

- Stacked pickup construction is a disclosed stand-in only.
