This is an SSL USB audio interface. I purchased it new in 2023. After using it a few times, I was given a Babyface, so it's been unused since. It has excellent reviews on Amazon, and I quite liked the sound it produced when the 4K button was pressed. There are almost no scratches, and it's in very clean condition. This is a listing for the main unit only; there are no accessories. ※There seem to be other models in the same series, such as the SSL2 mk2 and SSL2+mk2, but this is the SSL2. Please be aware.
