All the buttons, knobs, faders, displays and ports have been tested and are in good working condition. This item has some scratches on its casing and reader-board. There is some darker stained areas, mostly from continual use, in the front of the unit. Some of the black trim lines are worn off around the mix section. Some of the faders have a very minor little tilt when looking at them from the front, but they work great. It comes with its original Mackie power supply and a USB cable. It comes with the Pro Tools overlay on it. It does not come with any of the other DAW overlays. These may be purchased separately and easily put on.
