“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 and tone input lugs are jumpered as drawn on the source sheet.
  • Stereo jack ring switches battery negative to ground when a plug is inserted.

Connections

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

What each position does

SettingThe sourceEngine result
Always on (active)Passive simulation is not applied to active pickups; wiring topology only.No pickup reaches the output.

Not simulated: this circuit is drawn for reference only.

  • Active pickup gain and frequency response are not simulated.
  • The catalog active buffer is approximated with seymour-duncan-blackout-humbucker terminals.

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.
