“Example part” means any part with the same value and lugs will do; the source does not name a brand. “Generic” stands in for an unspecified pickup: check your own pickup's lead colours before you solder.
Specific to this wiring
- The sheet's title calls the two lower pots 'spin-a-split'; they are labelled 'Bridge tone 500k' and 'Neck tone 500k' and carry no capacitor.
- Each pickup's red & white leads go together to the middle lug of its spin-a-split pot; that pot's outer lug is soldered to its casing, and its other outer lug is left empty.
- Each pickup's black goes to its own volume's input lug; green and bare go to the solder spot on that volume's casing.
- Each volume's middle lug feeds one outer toggle lug; the toggle's middle lug goes to the jack tip, and its frame lug is wired to the neck volume's solder spot.
- The bridge volume's lower solder spot is wired across to the neck volume's solder spot; each volume's solder spot is also wired to the spin-a-split casing beneath it, and the two spin-a-split casings are wired together.
- The bridge ground wire and the jack sleeve both end on the bridge spin-a-split casing.
- The toggle lugs are not labelled in the source, so they are mapped by what each does.
- 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.
Understand this wiring

See the pickup, recognise its two halves, and learn where each coloured wire goes.
- Seymour Duncan coil splitting explained
A humbucker has two coils. See how a switch lets you use just one of them.

In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Rhythm (neck) | Neck pickup through the neck volume; its spin-a-split sets how far the series link is pulled to ground. | Neck pickup (both coils). |
| Both | Both pickups, each through its own volume. | Neck pickup (both coils) and Bridge pickup (both coils) in parallel. |
| Treble (bridge) | Bridge pickup through the bridge volume; its spin-a-split sets how far the series link is pulled to ground. | Bridge pickup (both coils). |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- Each spin-a-split is a 500k resistance from the pickup's series link to ground; the analysis reads it at full resistance (full humbucker). The partial and full split as the pot turns down is not simulated.
- Hum cancelling and phase describe the generic pickup models, not a measurement of any specific Seymour Duncan model.
- Pickup resistance is not specified, so no numeric meter readings are given.
Before you solder

Check before plugging in
- In each toggle position, the meter across the jack should read the selected humbucker, or both in parallel in the middle.
- With a spin-a-split turned fully down, its pickup's red and white should read as a short to ground (single coil).
- With a spin-a-split turned fully up, the red and white should read about 500k to ground.
Measure across the output jack with a multimeter on its resistance range. No exact readings are given where the source does not specify the pickups.
