I am not familiar with musical instruments, and the functionality has not been confirmed, so I am selling this as junk. No operational guarantee is provided after arrival. Please assess the contents and condition based on the images. The overall condition is poor. I will not be able to answer specialized questions, so please only proceed with the transaction if you understand this. Please refrain from purchasing if you are overly concerned about the condition, as this item has been stored by a non-professional.
