I LOVED this pedal, but there is a known issue where it randomly bricks. I pressed the loop to record something and all lights flashed yellow and stayed on. Unplugging and plugging it back in doesn't fix it, and trying to update it's firmware doesn't work because computers won't even recognize it in this state. Usually the fix is taking it apart and adjusting the SD card that holds the tracks you record, unfortunately in my case that did not work. Great pedal for a few months but ultimately broke down.
