This is a ZOOM B2 FOUR. I purchased it around March of this year and have primarily used it at home. I also used it in a studio, but it was a shoe-free studio, so I stepped on the foot switches in my socks. I am also selling a ZOOM case along with it. The case has a few scratches. The main unit is in good condition with no major scratches, but please understand that it is a used item. Thank you.
