The MXR M195 Noise Clamp is a pedal designed to clean up your signal path by offering a gate within an effects loop. So if you own a particularly noisey fuzz pedal for instance you can put it into the M195 Noise Clamp's loop and the Noise Clamp acts as a gate (purely for the signal that returns from the loop). That means the rest of your signal path and pedal board is unaffected! Watch the video below to see how this fantastic pedal works and how you can use it to reintroduce noisey or vintage pedals prone to hum into your pedal board while clamping down on the noise! Vintage tones without the noise!
Here's what MXR say about the M195 Noise Clamp
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.
