Early production models of Acoustic 100 & Acoustic 200 amplifiers with serial numbers that begin with CRIL16 or CRIA17 will benefit from a firmware update and we recommend that you update your firmware. Amplifiers with other serial numbers should already have the latest version of the firmware installed.

Disconnect the USB cable and power cycle your Amp to get back to normal mode.
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.
