I am a singer of jazz music, etc., so I bought this new for home practice and recording when I got a job. However, I bought it without any knowledge of home recording, so I never used it. Eventually, I learned about the Yamaha AG-03 and used that instead. Therefore, I am retiring this one, and it is in near-new condition. When I had music work, I would take things in and out of the storage box containing the equipment I used for recording at home. It was stored there, so there is some slight soiling, but it's not particularly noticeable, as you can see in the photos. I think it's a very good item for someone who knows how to use it ( ˘͈ ᵕ ˘͈ )❁︎ I'm thinking it's a waste, so I'd like to sell it. How about it? AC adapter is not included. I will include two new batteries. Dual audio interface, USB connection, with volume knobs. - Model name: iRig Pro DUO I/O - Accessories: USB cable, audio cable - Function: Dual audio interface - Connection type: USB connection - Control: 2 volume knobs Thank you for looking.
