Used only a few times. It has been used infrequently, and the functionality is almost like new. There are slight scratches on both sides, but the surface is relatively clean. Operation has been confirmed before listing. Sound output and knob operation are both fine. The original box has been disposed of, so this is a listing for the main unit only. Please note that the power cable (adapter) is not included. Please check the condition in the photos as this is a used item. The sound quality of the actual unit is, as expected, from Universal Audio. If you are looking for one, please consider it.
