This is a used YAMAHA AG03 MK2. Please check the condition of the outer box in the photos. I purchased this used a while ago, but I'm selling it because I no longer use it. There were no problems with its use. Although I don't see any noticeable scratches or stains, I've marked it as "Slightly scratched or dirty" to prevent any issues. Thank you for your understanding. Immediate purchase is OK. Please refrain from purchasing if you are concerned about minor imperfections, as this is a used item. Below is the product description from the official website: The AG03MK2 is the successor to the AG03, which has been refined to a higher level with a variety of carefully selected inputs and outputs, DSP effects, Loopback function, and all of them directly and easily controllable in a mixer-type product. It features a 4-pole mini input/output terminal to support new streaming styles, a mute button essential for live streaming, and improved sound quality due to improved power supply to the internal circuits. The AG03MK2 is the perfect live streaming mixer for building your preferred streaming environment by combining it with your favorite microphone and headset.
