My AD30VT XL has ceased to operate properly. It appears to be stuck on one (heavily distorted) model, no matter which model i choose - with the exception of the glass channel for which it just emits a fluttering noise. The effects knob seems to be affected the same - nothing works, but i do get a fluttering noise when it is rotated all the way to the left (as is the glass model)
I tried a factory reset to no avail. Since the master volume knob does work, I suspect the power amp section IS working and that this is related to the CPU/DSP. In manual mode i can't do much, and channel 2 seems to always mute the amp.
Has anybody had such problems? any advice?
