Tele with three single coils, volume, tone and middle-pickup blend

Three single coils · Three-way blade · One volume · One tone · One blend · .02 µF

A Tele with a middle pickup added. Neck and bridge run on a standard three-way lever switch into a 250k volume and a 250k tone with a .02 µF capacitor. The middle pickup bypasses the switch and goes through its own 250k volume pot, labelled 'blend', to the jack tip.

“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

  • The sheet has no switch-position legend. The lever-switch lugs are mapped by what they do (neck, both, bridge), as on the standard Tele sheet.
  • The middle pickup's white goes to the middle lug of the pot labelled Volume Pot "blend" 250k. That pot's left lug goes straight to the jack Tip, and its right lug is grounded to its casing. So the middle pickup is not switched by the lever switch.
  • Both the main volume's middle lug and the blend pot's left lug end on the jack Tip.
  • Lead colours are drawn, not printed: the sheet prints no lead names. Each pickup is drawn with one light-grey lead and one black lead, and several signal wires are also drawn light grey. The grey pickup leads are transcribed as white. Roles are inferred by function: grey = hot (it goes to the switch or the blend), black = ground (it goes to the Solder spot).
  • The middle pickup's white crosses the bridge pickup's white with no joint or hop drawn; they are transcribed as separate wires.
  • The blend control is drawn and labelled as a standard three-lug volume pot. The board uses the catalog's no-load blend pot, as directed for blend controls, and wires only gang A lugs 1 to 3.
  • The tone pot is drawn lugs down like the volume. Its right lug takes the signal from the volume, its middle lug the .02 cap, and its left lug is drawn empty.
  • The volume and tone Solder spots are joined by a line drawn dashed.
  • The 'Ground wire from bridge' ends on the volume's Solder spot.

Connections

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

What each position does

SettingThe sourceEngine result

Bridge, plus middle through the blend—Middle pickup and Bridge pickup in parallel.

Not simulated: this circuit is drawn for reference only.

  • blendNoLoad: the engine does not simulate the no-load blend pot, so positions are not analysed and the board is published topology-only.
  • The sheet gives no switch-position legend; the expected states follow the drawn wiring, with the middle pickup reaching the tip through the blend in every position. How much middle pickup you hear depends on the blend setting, which is not modelled.
  • Pickup resistance and magnet polarity are not specified, so no numeric meter readings or hum-cancelling claims 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 blend turned fully down (wiper at its grounded lug), each lever position should read the neck, both in parallel, or the bridge across the jack.
  • With the main volume at zero, the volume's middle lug should read as a short to the casing.

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.
