I've owned the ax8 for 2 yrs with no problems. Last friday, 12/27/19. And then saturday night at a gig, trying to hit a PEQ for a lead boost, pedal went down. No display, no button lights, input indicator still lit and showing a level. Very ragged, cleanish sounding output, display came back on, half the fractal startup text and logo with sporadic lines below that. Blinked, then everything came back on and it was fine. Unit kept in case always. Never wet. Knobs all very smooth. Always on good power. Any ideas what happened? First time on here. Hope I havent broken any rules.
