with one pickup, 3-Way Toggle Switch and Volume
Adding a 3-Way toggle switch allows you to use the Sustainiac on its own, rather than just as a sustain device, or in combination with the bridge pickup. It sounds remarkably like a regular single coil.
This diagram wasn’t available online, so after making this work on a customer’s guitar, I decided to share what I figured out.
The colours of the wires shown connected to the Sustainiac boards are the same as they are appear on the boards. The colours of other wires connecting the volume and output jack are used for illustrative purposes (ie. so you can tell them apart!).
