Here is a wiring scheme for a stratocaster. This wiring scheme let’s you control all the pickups. This way you will have tone control for the neck pickup and a tone control for the bridge pickup. When in the middle position you can control the overall tone with the tone pot 1(neck). Tone pot 2 is only for the bridge pickup.
In this scheme i used:
3x CTS 500K audio taper pots
2x Mallory 150’s .047µf capacitors
1x Treble bleed (for volume pot)
1x 3-way OAK lever switch
2x P90 handwound(by request) pickups
Vintage cloth wiring
