Hi, probably the same problem as my Pod. The problem occurred with the leftmost knob among the five knobs below the LCD screen of the Pod? I bought a pod in Japan on November 10th and it broke in about a week, and the one I sent for repair came back on November 27th, and today the knob in the same place stopped working again. I will contact Line 6 support tomorrow morning. I am disappointed with the second breakdown. If your Pod Go's stuck knob is in the same place, I'm guessing it's not a problem with how you or I are using it, but a problem with the design or durability of the part.
