Operation not confirmed. Numerous scratches and stains present. Since specialized operations such as sound production and tuning have not been confirmed, this item is treated as junk. One string is missing. Accessories: Case only. It is unknown if it is the original case. This item was received from someone else, and I do not have specialized knowledge. Therefore, I will refrain from confirming operation or responding to specialized comments. The switch in the 10th image is broken and pushed in.
