Using the Pedal

The guitar pedal comes with only three knobs: threshold, decay, and mode. The threshold refers to the sound level the signal must fall below before the device silences it. The decay indicates the time before the effect starts. You can turn the decay knob clockwise to get a more natural sound, but this also reduces the efficiency of noise cutting. The mode knob allows you to choose between two modes: mute and reduction. In the mute mode, the device cuts the noise when the pedal is off and mutes the sound completely when the pedal is on. This, for instance, is useful when tuning the guitar. In the reduction mode, nothing happens when the pedal is off and the device cuts the noise when the pedal is on. An LED light notifies you of the actual time the pedal cuts the noise.
