Crank your stomp pedals to the extremes without the fear of any hiss or excess noise with the MXR Noise Clamp. By sensing your guitar s dry signal, The Noise Clamp reduces the noise level within the effect loop, coming down hard on even the noisiest signals. A single Trigger knob allows you to set the volume threshold at which the pedal is active, and a green LED shows whether the gate is on off. This bad boy is capable of reducing Noise up to 26dB, maintaining riff definition at extreme gain levels.
