Firmware version REV 0510.Avid/Pro Tools Eleven Rack Multi Guitar Effects Processor & Audio Interface . Condition is Used. The unit is in great cosmetic condition, mint functional condition and has never left my smoke and pet free studio. From the front and back it looks mint, there's just a couple light scuffs where it's been put in and taking out of a rack unit, they're very minimal. Power cable will be included to get you up and running straight away and I've reset it to factory defaults so it's ready to go for you. Dispatched with Royal Mail 1st class. Only selling cause i have gonr back to useing floor units. U.k. bidders onky please.
