This is a used YAMAHA EZ-AG Easy Guitar. The AC adapter is not included, but operation has been confirmed using AA batteries. If you need an AC adapter, you can purchase a PA-3C or PA-130B on Amazon or Mercari. 〈Operation Check〉 The LEDs on the 7th fret and beyond do not light up. It is suspected that there may be a circuit malfunction, disconnection, or solder cracking, but the inside has not been opened, so it is unknown. However, it has been confirmed that it operates normally except for the non-lighting LEDs. 〈Condition〉 ◆ There are minor scratches due to use. ◆ There is no rust in the battery box. Please check the other conditions in the photos. The item will be shipped with waterproof packaging.
