SG wiring
2 SG wirings side by side, each with its full diagram and every sound it makes — series, parallel, phase and hum-cancelling worked out per switch position.
Modern wiring (2V2T)
same circuit as Les Paul
Parts
- Neck humbucker (4-conductor)
- Bridge humbucker (4-conductor)
- 3-way toggle
- 4× 500k audio
- 2× 0.022 µF tone cap
| Sound | Switch setting | Hum-cancelling | Phase |
|---|---|---|---|
| Neck humbucker | 3-way toggle: rhythm (neck) | Yes | In phase |
| Bridge humbucker + Neck humbucker | 3-way toggle: middle (both) | Yes | In phase |
| Bridge humbucker | 3-way toggle: treble (bridge) | Yes | In phase |
Wiring list
Every wire in solder order — grounds first, output last. The list is generated from the same netlist as the diagram.
- Solder a black wire from the second leg of 0.022 µF to the second leg of 0.022 µF.
- Solder a black wire from the second leg of 0.022 µF to the south start lead from Neck.

Something wrong, or missing?
A wrong diagram is worse than no diagram. If a lug, a colour or a sound looks off — or your guitar is not here — say so and it gets looked at.
