“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 Relentless Middle Plug-In is drawn with WHITE and BARE leads and a BLACK series link between the coils.
- WHITE goes to the volume's input lug; BARE ends on the volume casing.
- The volume's ground lug is bent onto the casing. TO BRIDGE GROUND ends on the volume casing.
- The tone is drawn with its lugs up. The volume's input lug jumps to the tone's left lug; the .033µF capacitor (EP1033) sits on the tone's middle lug with its other leg on the tone casing.
- The jack lugs are not labelled in the source: the lug fed from the volume's middle lug is the tip and the lug wired to the casing ground is the sleeve.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

What each position does
| Setting | The source | Engine result |
|---|---|---|
| Always on | One P-Bass, no selector. | Relentless Middle. |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- The P-Bass is modelled as a generic single coil; the split-coil/hum-cancelling construction is not modelled.
- The source's custom-taper pots are not reproduced: both pots are simulated with a linear track, so settings between the knob ends are approximate.
- Tone capacitor value matches the printed .033µF.
- 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
- With both pots up, the meter across the jack should read the pickup resistance.
- The jack sleeve should read continuity to the volume casing, the tone casing and the bridge ground wire.
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.
