edster7 Posted November 10, 2016 Share Posted November 10, 2016 JM4 works ok when switched on. After approximately 20-30 mins the unit trips into Demo mode and screen goes fuzzy. I have updated the firmware and even changed the power supply with no luck. Pedal works again after leaving the unit off for a while.Then it repeats the same problem. Anyone can help please?
