Replacing the pcb

Gibsons come with mass produced pcb control circuits. Which is fine, certainly makes it easier to maintain a standard quality and if anyone has seen the awful wiring they had in the 70s you'll understand why...

The downside of this is that it's much harder to modify just a part of the circuit such as fitting a split coil switch.

So this is me replacing the wiring...


The molex style connectors make it easy to remove the whole of the pcb but once you've snipped them off you're well and truly committed to the rewire!


Mass produced pcb vs hand wired custom loomwith cts pots and orange drop caps and trim pots to adjust the amount of coil cut when the switch is pulled.


All wired in and working nicely. The trim pots allow for adjusting the amount of coil cut. When you turn a humbucker into a single coil they often sound thin and weedy, this prevents that thus allowing a good range of sounds to be gained from full humbucker to a more true single coil sound.
