Hi, I have a pod studio GX (the little one), and every once in a while when I'm playing, I'll hear a little static pop noise. It's completely random. I've tried using different usb cables, 3.5mm cables, different USB ports, and unplugging the instrument cable. Nothing fixes it. It seems like it takes a while for it to start after unplugging the unit, but when it does it's probably happening on average every 10 seconds. It's incredibly annoying, and comes through the recordings. Has anyone else experienced this issue and had any luck with it?
