## Parts and values

- Neck pickup: Neck pickup; generic (Humbucker (four-conductor, Seymour Duncan colours))
- Middle single coil: Middle single coil; generic (Single-coil pickup (two-conductor))
- Bridge pickup: Bridge pickup; generic (Humbucker (four-conductor, Seymour Duncan colours))
- 5-Way Blade Switch: 5-Way Blade Switch; compatible example (Oak Grigsby 5-Way)
- Volume 250k: Volume 250k; 250k; compatible example (CTS 250k Audio Pot)
- Tone 1 (neck): Tone 1 (neck); 250k; compatible example (CTS 250k Audio Pot)
- Tone 2 (middle): Tone 2 (middle); 250k; compatible example (CTS 250k Audio Pot)
- .047 cap: .047 cap; 47nF; compatible example (Orange Drop .047µF)

## Specific to this wiring

- Two Strat tones share one .047 µF capacitor via a jumper between tone-2 wiper and tone-1 capacitor lug; passive tone analysis is topology-only (toneReachesSignal).
