Thank you for viewing. This item has been left unused for a long time. I am listing it because I haven't used it. Simple sound output check completed. There may be noise or crackling during sound adjustment, but sound was produced. * The sides are discolored due to sun exposure. I am selling this as a junk item, so I would appreciate it if you could understand this before purchasing. Please understand that there may be stains and scratches as this is a used item.
