I am using HD 500x for about half a year. The problem started week ago. I am using ABCD mode for switching presets.
When I switched for B,C or D preset it automatically is switching back to preset A and I can not switch to any other preset. Even when I am using preset A and I am trying to use any of the additional switches to add delay, reverb or whatever other setting assigned to top 4 switches it is coming back to original. It happens after 10 or 15 minutes of normal use. In the worse scenario I can not use Tuner because it is keep on switching back to preset A.
I used monkey to reload flash and it did not change anything. I am using normal guitar and variax. I was thinking that maybe my variax cable is making that error but it is not the case.
Please help solve this problem. Right now HD 500x is completely useless.
