: : anyone got a wiring diagram for a vox custom electric guitar,,,it has 2 humbucker holes and 2 volume 2 tone and 2 switches??i needs some help please,,many thanks chris:) uk I have one (Canada) and had the bridge pick up changed. The switch near volume and tone controls whether your humbuckers run as is (middle position) or split as single coils in series or in parallel, either sounding thinner or much much bassier… I love that guitar.
