Here is the "Vintage Style" original switching wiring kit for Gibson and Epiphone SG guitars with a 3-Pickup configuration. These each use CTS 450G Audio Taper Potentiometers. Each listing is the same with the exception of the capacitors used.
The two other 3-Pickup SG wiring kits that are offered with these CTS 450G Audio Taper Potentiometers are the "Frampton Style" and "3-Volume / 1 Tone".
Each harness is made to order with extreme care and concern. If you'd like to customize your harness beyond what is available utilizing the drop down menus within the listing, please reach out to confirm availability.
