Building a killswitch pedal

 

Here I built a small and handy pedal that kills the sound. You can position it right after the tuner (my tuner is always on and doesn't kill the sound output). 

Two input jacks and one SPDT are required. The wiring is very simple.

A few minutes of work and you get a handy pedal for your pedalboard.

I decided to name it "Lull" :)
