Seymour Duncan wiring

One humbucker with one volume

One humbucker · No switch · One volume · No tone

A four-conductor Seymour Duncan humbucker in its standard series wiring, through a 500k audio-taper volume to a mono jack. The red and white leads are joined and taped off.

“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

  • Solder the red and white leads together and tape the joint off; it connects to nothing else.
  • The pickup's black lead is the hot output in Seymour Duncan's colour code.

Connections

In soldering order: grounds first, then the switch, the pickups and the signal path. Choose Show to highlight a connection in the drawing.

What each position does

SettingThe sourceEngine result
Always onOne humbucker, both coils in series, no selector.Bridge pickup (both coils).

Checked with the Tinkercaster wiring engine against the switching the source describes.

  • Hum cancelling and phase describe the generic pickup model, 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

  • With the volume up, the meter across the jack should read the full humbucker's resistance (both coils).
  • The taped red–white joint should read open to ground.

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.
