Hey guys, I own a V-amp 3, and ever since I've had it, I've had the issue of it not saving my presets. I'd set them up, save 'em, and I'd be able to switch between them, no problem. But when I turn it off, and turn back on, all my settings are wiped, and I have to start again. The manual offers no help on this, so any you guys have would be appreciated
