Thank you for viewing. Roland MC-505 Groovebox Rhythm Machine (Junk) The display is broken as shown in the photos. Power and sound output have been confirmed. Although it's junk, the knobs and buttons function normally, except for keys 1, 2, and 3, which have slightly poor contact. Please understand that this item has been stored at home, and we appreciate your purchase. Also, please note that I may not be able to respond immediately due to work commitments.
