IMPORTANT NOTE:

After updating firmware, if you use a footswitch, we recommend re-saving presets to all three preset positions on the footswitch. Firmware update does not overwrite footswitch presets.  In rare cases, presets saved with an older version of firmware can cause problems after a firmware update.   Problems may include improper footswitch operation or even amp crash or freeze.  Saving presets with the new firmware to all three presets will eliminate any problems.
