Some amp functions are inverted, which means that the function is deactivated when the switch is closed (activated). Reverb is the most likely function to show this issue. This is easy to fix:

  1. Power down your Gizmo
  2. Hold the 2 button as you power up the Gizmo
  3. Keep holding until the lights flash
  4. Release the 2 button and press the button(s) that need to be inverted. They will light up
  5. Press the Write button to save the new settings


Please note that this applies to the Amp Gizmo (version 2), Mini Amp Gizmo and Switch Gizmo
