Multifunction DJ mixer, Serato compatible, equipped with 8 control knobs and 2 faders. There is some yellowing on the buttons and some rust on the surface, but it works normally. I don't think there is any tobacco smell, but as it was used in a studio where smoking is allowed, please refrain from purchasing if you are concerned. - Model name: mixars DUO - Brand: Serato - Number of control knobs: 8 - Number of faders: 2 - Number of buttons: 8 Only the main unit and AC cord are included, no original box, and will be shipped in a separate box. Thank you for viewing.
