This is a VOX Dynamic Looper. I bought it used, but I have no idea how to use it... (I can download the manual from the web, but I didn't understand it even after reading it) As shown in the photos, I have confirmed that it powers on. I haven't checked the sound output or operation because I don't know how to use it, so I'm selling it as junk. During testing, I confirmed that it powered on with a general-purpose power adapter, but there are no accessories, including the original power adapter. This is a listing for the main unit only. Here are the product specifications. Dynamically control loop phrases!
