Thank you for viewing. This is a Roland SP-808. I am selling it because I no longer use it. *Please check the photos for some scratches due to aging and color changes on the mixer knobs. I will clean it before shipping it from the condition shown in the photos. - Power on confirmed - Sound output confirmed from the main unit's line out *Due to its many functions, only the above have been confirmed, and not all functions have been checked. *Main unit and power cable only (ZIP disk not included)
