SNG-20 | Noise Gate Pedal


Let The Quiet Moments Be Quiet Moments.

The SNG-20 Noise Gate is the guardian of your signal. Noise Gates are kind of like Compressors in the fact that they attenuate signal. Whereas Compressors attenuate signals above a threshold (to even-out dynamics and attack in an audio signal) a Noise Gate attenuates signals below a threshold. This allows you to keep unwanted hum, buzz, and other noise out of your mix. On the SNG-20, you'll see one main knob labeled Threshold. Adjusting this knob clockwise (toward +10dB) you raise the threshold. Counterclockwise adjustment lowers the threshold. The higher the threshold, the higher your signal needs to be to open the gate. The toggle switch on the top adjusts the attack of the Noise Gate. Setting to Hard makes the attack and release very quick/sudden. Setting to Soft will give the attack and release more of a "fade-in-fade-out" quality.

Detailed Operation

The Noise Gate Guitar Effects Pedal from CNZ Audio effectively tames your guitar signal, overdrive pedals, and entire effects chains! This pedal is perfect if you’re trying to reduce buzz in your signal while you aren’t playing.

The Toggle Switch has two settings, Hard and Soft. The Hard setting adjust the pedal so that it’s release is almost immediate. The Hard setting is perfect for getting rid of unwanted string noise and creating clean silence in between the notes of a heavy-metal riff. The Soft setting eases up on the release and allows it to end less abruptly.

The Threshold Knob adjusts when the Pedal will begin cutting off a signal. If you set the Knob to -30 DB, the pedal will cut off any signal that is lower than that value. Setting the Threshold to higher values like +10 can create some great effects with Reverb and Heavy Distortion!

The True-Bypass Footswitch allows for your tone to come through the pedal unaffected in the “off” position.
