Support / Archtop Humbucker Pickup Wiring Diagram & Fitting Instructions
There are a couple of different locations that musicians use to mount the guitar electrics on a Archtop Guitar.
A. Through the sound hole and then fitted to the body like a Hollowbody.
- You will need to check the size of the holes for the pots as on some guitars they are drilled small for cheap electrical components. If they are small, the best way to enlarge them to 10mm to fit CTS pots, is to use a round file.
- You are now ready fit the new harness.
- Place the new harness on top of the guitar
- Solder the 1 x ground bridge wire to the back of the new tone pot (refer to wiring diagram)
- Solder the pickup wires to the new pots (refer to wiring diagram).
- Once this is done, you should test to make sure everything is working.
- You will now need to thread the harness into the guitar to the correct holes. Start with the jack socket, you may need a bit of fishing line to help you feed the jack into place, now everything else will follow. Take you time with this part so you don’t damage any of the components.
- Re the control knobs.
- Fit the pickguard back into place and you are ready to go.
