Support / Gibson Sonex Wiring Diagram & Fitting Instructions

- Find somewhere safe, dry and secure to place your Sonex guitar while you work on it.
- Remove Strings.
- Undo the screws that hold the pickguard to the body.
- Carefully lift the pickguard up and cut all wires from the body to the pickguard closest to the pots. These are a few ground wires (normally black in colour).
- Put the guitar safely out the way for the time being.
- Working on the pickguard, cut the 2 x pickup ground wires from the back of the pots, Normally soldered to the volume pot.
- Cut the 2 pickup hot wires from the pots leaving the wires as long as possible.
- Undo the pot, switch and jack holding nuts from the front of the pickguard
- You should now be able to remove all 4 old pots switch and jack from the pickguard.
- At this point you may want to clean the front of pickguard where the old pots have been.

- Solder the 2 x ground pickup wires to the back of the new volume pots (refer to wiring diagram).
