Panic Button Mute / Kill Switch Pedal Slice up your signal with the Sketchy Sounds Panic Button. Create your own manual tremolo effect, momentarily mute your signal for silent tuning or stomp in a panicked frenzy to create all sorts of rhythmic, stuttering mayhem. No need to add power, the Panic Button is completely passive. Just throw it in line with the rest of your guitar pedals and get to stomping.
