This unit has been used by me for a few years, but not intensely. There are some marks from going in and out of racks, but the unit is in great condition. The last few years it lived in a studio.

Unit has been tested and everything works as it should. No noise, no crackling, just like it was new. It's a great-sounding unit with a clean sound. Pre-amp is great, EQ is very nice and the compressor is soft-knee with a lot of versatility. Derived from the legendary Focusrite consoles designed by Rupert Neve.
