The optional G-switch for the Nova System.
With this switch you can use the Nova System in pedal mode. Each of the three switches on the G-switch selects a preset out of the current bank of three. Once the preset is loaded the Nova System becomes like a pedalboard, with compression, boost, reverb, pitch shifting, modulation, delay, tap tempo and distortion available to turn on and off at will. With a long press of either the left or right buttons you can change preset banks either up or down.
