For sale is a BOSS KATANA-AIR-R wireless amplifier. This is a 2021 Ikebe Gakki Shibuya open記念 collaboration model. I am selling it because I purchased another amplifier. There are no stains or scratches on the exterior. I have confirmed that it works without any problems. Accessories include the power adapter and the box. I will pack the included box with bubble wrap and ship it.
