“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 neck humbucker's black lead goes to the neck volume's input lug; its green and bare leads go to the neck volume's solder spot.
- Red & White wires get soldered together and taped off: the humbucker's red and white leads are joined, taped, and touch nothing else.
- The bridge single coil's white lead goes to the bridge volume's input lug and its black lead to the bridge volume's solder spot.
- Each volume's middle lug goes to a common lug on the switch: neck volume to the top-right lug, bridge volume to the bottom-left lug.
- Three short jumpers join four of the other switch lugs into one output, which runs to the jack tip. Two lugs stay empty.
- The two volume casings are joined, the bridge volume casing goes to the jack sleeve, and the bridge ground wire ends on the neck volume's solder spot.
- The source does not number the switch positions; the lugs are mapped by what they do (neck, both, bridge).
- Jack legend: Tip (hot output); Sleeve (ground), the inner, circular portion of the jack.

What each position does

| Neck + bridge | — | Neck pickup (both coils) and Bridge pickup in parallel. |
| Bridge | — | Bridge pickup. |
Checked with the Tinkercaster wiring engine against the switching the source describes.
- 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
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
- In each blade position, the meter across the jack should read the selected pickup, or both in parallel in the middle.
- With the selected pickup's volume at zero, tip and sleeve should read as a short.
- The taped red and white joint should read open to ground and to every other lead.
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.
