The Ampero Mini by Hotone. I'm selling it because I'm changing my equipment. It's also excellent as a looper, and it was recently featured in a ukulele magazine. Included: AC adapter USB-C to A cable (can connect to a computer) Can also be used as an audio interface. Excellent for beginners in DTM (desktop music production). This is an authentic product from All Access, so you can be assured of its quality. Regarding the serial number sticker on the back, it peeled off a little when I tried to incorporate it into an effects board. Never used live. As you can see in the photos, it's been used relatively cleanly. Please read my profile.
