I bought my UX2 one year ago and it worked fine. I've been recording voice and instrument tracks last year without problem. Today, after months without using my UX2, I wanted to record an instrument track, but when I pluged my guitar and selected the instrument input in POD Farm 2 nothing happened. The analog panel of the UX2 shows that it's not receiving input signal. I already checked the guitar and the cable on my amp and they work fine so the problem is from the UX2. I tried then with my mic and that input works fine, and my UX2 is receiving the feedback signal from my computer too. What can I do to make the instrument input work again?
