This belonged to my deceased grandfather. It has some scratches, stains, and signs of wear and tear, indicating its age and use. One string is missing, so please restring it. There are several signatures on the back, but I don't know whose they are. Since it belonged to my grandfather, I cannot answer detailed questions. Regarding functionality, I am not familiar with instruments, so I have not tested it. I am selling it as a junk item. Please consider this a defective item, assuming that you will have it repaired or maintained. Also, I have not checked the condition beyond what is described, and any issues with unconfirmed parts are not eligible for returns or refunds. Therefore, please purchase only if you understand and accept no returns/no refunds (NC/NR). This is a sale of the main body only. There are no accessories. ※ The power cable is directly connected to the main body. This is a one-of-a-kind used item. If anyone is looking for one, why not take this opportunity? ☺︎
