With your serial number you can check how old the device is.
Just ask the Eventide customer service. They are very friendly and really fast. Unfortunately not the standard for that business.
Don’t worry if the device is an older one. Digital electronics normally never fail. Maybe some mechanical parts like footswitches fail. Exchange of mechanical parts isn’t a big thing. As long as you don’t have problems installing the newest software just be happy. If you want to sell the H9 again the price is nearly independent from the age of the device.
