Hello guys. Any idea how could I solve the following issue please? When I have the Zoom G1Xon multi effect connected to my computer via USB (audio output to my guitar amp), I get quite a lot of static noise, high-frequency buzz, fuzz and hum, which gets so much worse when I switch to the lead channel on the amp itself. Not only it adds a layer of noise over the sound, but it even impacts the underlying guitar tone quality noticeably. When I use the very same USB cable and plug it into the old phone charger directly to the wall power socket instead, the noise disappears (also disappears when I power the G1Xon via the AC/DC power adaptor). I tried to touch the metal PC case to see if I could ground it, but the noise remained the same. Also tried powering the device via AC/DC adaptor and at the same time just connecting it to PC via USB. All fine and dandy but as soon as I plugged it into PC USB slot the noise came back. I tried using different USB inputs on PC as well as trying a different mini USB cable altogether, to no avail. Now, if I only used the USB cable to power the device, it'd be a non-issue since I'd just use a different power input. But since I'd love to use the G1Xon with Tonelib on my PC, that's not really a solution. Any ideas guys?
