Presonus FireStudio Mobile FireWire Audio Interface : used $150

I used this temporarily in my studio as I waited for my Motu to be fixed. It was used in a smoke free studio and everything is working 100%. One knob is missing, only reason it was missing is because of the spot i needed to put the interface it could only sit there if the end knob was off. I am stupid and misplaced the knob. I can give another knob that is similar... but you don't really need the knob as its a long enough stem to turn anyways...

As you know Presonus makes a great soundcard. sounds wonderful, I was almos tempted to just keep it and sell the Motu, but the Motu fits my setup better. I will sell it for $150. Below is the description of the piece from the manufacturer.
