“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
- Volume push/pull grounds all three SCH series links when up, per the source arrows.
- Middle SCH uses red hot lead on the sheet; neck and bridge use black hots.
Understand this wiring
- Seymour Duncan humbucker wire colors
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.
- Reading Seymour Duncan push/pull switch diagrams
Turning the knob and pulling it do different jobs. See the actual part, then try its switch connections.
Connections
In soldering order: grounds first, then the switch, the pickups and the signal path.

Checked with the Tinkercaster wiring engine against the switching the source describes.
- Three-way coil-split on one DPDT push/pull is transcribed as drawn; pull/up position analysis is topology-only.
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
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.
