Two humbuckers · 3-way toggle · 2 volumes, 2 tones · 50s wiring
Wolfetone 4-conductor humbuckers, standard series wiring. Tone cap fed from the volume output: turning the volume down keeps more treble.
Step by step
- Neck pickup RED (hot) → right-hand lug of the neck volume pot.
- Neck pickup GREEN + WHITE → solder together, insulate with heat-shrink or tape. They connect to nothing else.
- Neck pickup BLACK (ground) → ground (back of the neck volume pot).
- Neck pickup BARE shield → ground, with the black wire.
- Bridge pickup RED (hot) → right-hand lug of the bridge volume pot.
- Bridge pickup GREEN + WHITE → solder together and insulate. They connect to nothing else.
- Bridge pickup BLACK (ground) → ground.
- Bridge pickup BARE shield → ground, with the black wire.
- Neck volume LEFT lug → bend it down and solder it to the back of the pot (ground).
- Bridge volume LEFT lug → bend it down and solder it to the back of the pot (ground).
- Neck volume MIDDLE lug → neck lug of the 3-way toggle.
- Bridge volume MIDDLE lug → bridge lug of the 3-way toggle.
- Solder one leg of the .022µF capacitor to the neck volume MIDDLE lug (together with the wire to the switch).
- Solder the other capacitor leg to the neck tone MIDDLE lug.
- Neck tone LEFT lug → bend it down and solder it to the back of the pot (ground). The tone pot’s right lug is not used.
- Solder one leg of the other .022µF capacitor to the bridge volume MIDDLE lug (with the switch wire), and the other leg to the bridge tone MIDDLE lug.
- Bridge tone LEFT lug → bend it down and solder it to the back of the pot (ground). The right lug is not used.
- 3-way toggle OUTPUT (center) lug → TIP lug of the output jack.
- Output jack SLEEVE lug → ground.
- 3-way toggle frame ground lug → ground.
- Run one ground wire joining the backs of all four pots, the switch ground, the jack sleeve and the bridge/tailpiece ground wire.
Before you solder
- Pots are shown from the back with the lugs pointing up. Turning a knob up moves the middle lug’s contact toward the right-hand lug.
- Before soldering the switch, check it with a meter: in the neck position, the outer lug that connects to the center lug is the neck lug.
- Jack: the tip lug is on the long springy arm that touches the tip of the plug; the sleeve lug is on the frame.
- For the "modern" version (tone fed before the volume), see the other two-humbucker diagram. Never join red to black: that shorts the pickup.
