Yamaha Guitar Amplifier HY-10GⅢ I am selling this as I no longer have a use for it. I've had it at home for about 10 years. Currently, I don't have any instruments at home, so I can't actually connect it and check its operation, but the lamp came on when I plugged it in and switched it on. However, please understand that this is a used item. There are scratches and dirt as shown in the 5th and 6th photos. There are also white marks on the front. Thank you.
