Will this fit my guitar?
Our pre-wired ES-339 Vintage Wiring harness is wired to fit all models including Gibson & Epiphone. If installing into an imported model or a DIY guitar kit you will need to ensure the Potentiometer holes will take CTS pots (approx 10mm). This can be done using a round file or carefully with a 10mm drill.

Useful Tip 1
I think it would be a good idea to mention at this point if you are thinking of changing your pickups on your Gibson & Epiphone ES-339, this would be the time to do it, as changing pickups will involve the removal of the wiring harness, so best to do everything at the same time.
Useful Tip 2
Because of the construction of a Gibson & Epiphone ES-339, you will be able to have everything soldered up to the harness and strings fitted to allow testing before the wiring harness goes into the body. Its a great time to test your pickup soldering to the Potentiometers.
