This is a YAMAHA FG820 acoustic guitar. This guitar is characterized by its high-quality tone and comfortable playability. It produces a wonderful sound that lives up to the YAMAHA name. The well-defined bass and clear treble are exquisitely balanced, making it suitable for any genre of music. Please refer to the photos for the condition. I don't have much knowledge about it, so details are unknown, but I can provide additional photos if needed.
