This is a simple and very convenient mute switch that completely cuts off the input when you press the footswitch. It has a built-in LED that lights up in two colors, red and blue; the blue light illuminates when a signal is flowing, and the red light illuminates when it is muted. It is not a momentary switch, but a latching switch that stays in place after being pressed once with the footswitch.
