TC electronics Nova System, comes in original box, and includes optional TC Electronics G-switch 3 button foot switch ($50 aftermarket add on). Unit is in overall excellent condition with the only physical wear being some light scratching on the metal housing/plastic display.
By far the best sounding effects unit I've ever owned (and in my opinion on the market for under $800 or so) and it's built like a tank. $360 shipped/insured/paypal'd within the US, will ship outside US but buyer pays all shipping and insurance costs.
