Behringer NR300 Noise Reducer - NOISE GATE PEDAL EFFECT FOR GUITAR

(This text is machine translated) The NR300 actually works like two pedals in one. In Reduction mode you can adjust the Threshold and Decay knobs to keep all the sound and dynamics intact, but it actually eliminates the hum from the scene. In Mute mode, the NR300 becomes a super quiet On / Off switch for your instrument.
