I’ve posted before about a problem with my SD Card in the 45000 unit – this was resolved. And had no problems with it since, using it in a surface mounted setup… hint hint… the primary issue is actually the footswitch.

As soon as I plugged it in and went to perform any footswitch action, it triggers the above problem (which itself I can thankfully now sort in a couple of minutes). I inspected inside the footswitch unit and it is pristine, tried a range of known working conxn cables, inspected/lite-cleaned the cable contact in the main unit, all seems fine. Reproduced the issue multiple times, no doubts. Guessing a terminally fried chip or something in the switch, but any useful input here would be much appreciated!
