Step 4: Adding switch control
If your not lucky enough to be replacing an existing POT with a push/pull POT, then you'll have to find a place to install your new switch or new POT. You'll have to carefully drill the hole and put it in it's place. I used a little slide toggle that needed a rectangular hole, so I cut it out with a dremel.
If you're just adding a switch like I did, then all that's left to do is connect the new wire from the pickup to one side of the switch and a wire from the other side of the switch to ground. My switch is a DPDT type so that I can connect both of my pickups this way. I had considered 2 switches so that I could change them independently, but I was lacking the space inside the cavity of my guitar.
That's it! I encourage you to explore some of the other options in the schematic drawings though. There might even be a great idea that i missed!
