How to Understand Noise Suppressors on Pedal Boards

The noise suppressor, also called a noise gate, is an audio filter. The audio level of the signal that passes through the noise suppressor signal is inhibited by the pedal. The audio signal output by the noise suppressor is determined by the volume level of the guitar.

Difficulty: Easy

Instructions

1. Set the guitar to play with a heavily distorted sound. In this mode, the noise suppressor will shut off the distortion during the more staccato chords. This allows the individual notes of the chord to be heard without the heavy feedback.

2. Use the noise suppressor pedal when tuning the guitar. The clean, undistorted sound is necessary for properly tuning the guitar. This is necessary for the final tune-up, after all the equipment has been moved on stage.

3. Use the noise suppressor pedal during a concert to cancel the feedback from the guitar amp. Audiences don't enjoy the constant buzz and hum in the background between songs.

4. Check the noise suppressor settings before a performance. Individual guitar players or the audio technicians should establish the signal levels and pedal settings before any live performance or recording.
