I have a new HX effects (bought at Guitar Center ~4 weeks ago).
Software version: 2.60.
While running in 4CM methods, configuring presets for >30 minutes, display indicators stop working. Reboot, all cables out, firmware reinstallation don't help. However, if keep unit off for ~10 minutes and turn it again, indicators work again. So, I assume it's heating problem.
So, I plan to return it back to Guitar Center and replace with new one. But, could you please let me know, whether it's known bug, whether it's software or heating issue?
