“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
- When the 3-way selector is in position 2, tone pot will be: series = pulled, and parallel = pushed.
- The push/pull only changes the middle position; the neck and bridge positions sound the same either way.
- The neck pickup's black lead goes to the volume input, not to ground; its white lead goes to the switch.
- The bridge pickup's red lead goes to ground (the volume casing) and its green lead goes to the switch. Its black and white leads are joined and insulated; the joint touches nothing else.
- The neck pickup's gray lead goes to the volume casing. The board does not draw it, because the stand-in single coil has no third lead.
- The switch tags and the push/pull tags are not labelled in the source, so they are mapped by what each does.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Neck | — | Twang King neck. |
| Neck (tone pulled, no change) | — | Twang King neck. |
| Neck and bridge in parallel | parallel = pushed | Twang King neck and Chopper T bridge (both coils) in parallel. |
| Neck and bridge in series | series = pulled | Twang King neck and Chopper T bridge (both coils) in series. |
| Bridge | — | Chopper T bridge (both coils). |
| Bridge (tone pulled, no change) | — | Chopper T bridge (both coils). |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- The source's custom-taper volume is not reproduced: it is simulated with a linear track, so settings between the knob ends are approximate.
- Hum cancelling and phase describe the generic pickup models, not measured DiMarzio pickups.
- Pickup resistance is not specified, so no numeric meter readings are given.
Before you solder
Ticks are kept in this browser only, as a reminder. They are not a check of your joints. New to soldering? Read the soldering cheat sheet.
Check before plugging in
- Position 2 with the tone pulled: the reading across the jack should be higher than either pickup alone, because the pickups are in series.
- Position 2 with the tone pushed: the reading should be lower than either pickup alone (parallel).
- Positions 1 and 3 should read the same whether the tone is pushed or pulled.
- The taped black–white joint on the bridge pickup should read open 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.
