Some how, I was playing with my foot switch and erased all of the presets, leaving me 2 channels, working on clean. The other 2 channels, od1, and # 4 crunch, do not work. Can anyone help?
Hello,
We would recommend reinitalising the amplfier and footswitch, this will empty it back to factory pre set and then you can re store your settings.
Kind Regards
