“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

  • 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).

Connections

In soldering order: grounds first, then the switch, the pickups and the signal path.

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.
