There are two Noise Suppressors available in the GT-10.
Use the following steps to access the Noise Suppresors and adjust their settings:

1. Press the MASTER/PEDAL FX button.

2. Press CURSOR right or left to select NS-1 or NS-2.

3. Press CATEGORY/ENTER.

4. Press MASTER/PEDAL FX so that "ON" is shaded in the lower right corner of the display - this turns on the Noise Supressor you selected in Step 2.

5. Use the CURSOR buttons to navigate to the desired setting (Threshold, Release, Detect), and then use the VALUE dial to adjust the value.

If desired, press WRITE twice to save the new settings to a User patch.
