ASK-HBS – Single Humbucker Les Paul JR.

ASK-HBS - Single Humbucker Les Paul JR.



I found your article on the DPDT switch and coil splitting. I’m trying to help my nephew wire up a modified Les Paul JR with a single humbucker with 1 volume 1 tone plus an on-off-on switch. Your diagram is the closest I’ve come to finding one online – do you by any chance have a diagram with both volume & tone and not just volume?

Thank you in advance,



Hello Marshall, thanks for the great question! I think I can help you out.  The good news is that it’s pretty simple, and you can begin by wiring the guitar exactly as it’s shown in the diagram you sent.


Once you have that wiring complete, you can add the tone function by connecting just two wires and adding the capacitor. I’ve included the complete diagram below.


That should get you going. Let us know if you have any problems or other questions.

Thanks for reading Humbucker Soup!
