Your pedal's firmware can be viewed in a .TXT file stored on the pedal's hard drive. To view this file, you will need a USB mini B cable and a computer.
1. Hold down the left footswitch and connect your power supply. The LED will blink several times and then turn solid. This is 'Mass Storage Mode'.
2. Connect your pedal directly to the computer with the USB cable. The drive should appear on the desktop (also in File Explorer on Windows, or Finder on a Mac)
You can also view the firmware version on the Config tab of the web editor.
