I had the same thing happen to me during the middle of a gig. About 2/3rds into the gig my pedal just froze and I couldn't turn different effects on or off. I also couldn't switch to a different pedal board. After the gig I did a factory reset and firmware update, but the problem kept coming back. I took the pedal into a company approved repair center and they told me they fixed the problem. I got the hx effects back and started using it again right away. It was working fine for 5 days, but now it is right back to where it started. It keeps freezing on me and honestly I would really like a new unit since it is still under warranty.
