【Please be sure to check the product description】 Operation confirmed, works well. Purchased new on Amazon in September 2023. After that, it was only used at home, not in live performances or studios. Therefore, I think it's in good condition. I'm not good with machines and couldn't use it properly, so I'm selling it. What I'm selling this time is the main unit, adapter, and outer box. Operation has been confirmed by connecting to a PC and amplifier. The license has been used once.
