True Bypass / AB Box Circuit

Back to basics; here is a super simple true bypass pedal. It can be used to bypass a chain of effect pedals with one switch, to switch between two sources (eg, two guitars), or to switch between two outputs (eg, an amp and a tuner).

 The pedal uses a DPDT foot switch, 4* 6.5mm jacks, and the project should cost ~$25.

The project is entirely point-to-point wired.
