Wow.. that totally sucks....Just imagine: You buy the most expensive car on the planet, it arrives at your place and it doesn't work properly. How would you feel? The Axe Fx III is by now the most expensive guitar modelling device on the market. I had the Ultra fail on me because the cheap fan broke, I had the II where an eprom died(if a remeber right, need to check the mail from g66) and I had the II XL and the powersupply died.
I've owned the Ultra, a pre-production (no serial #) AF2 and the AF2XL, and NONE of them have had a single issue. Having been a long-time FAS beta tester, I've installed a LOT of non-public firmware releases and tested with as many (or more) non-public AxeEdit versions over my 10 or so years being associate with FAS. Never had a problem..
Sorry to hear.. hope this one will work for you.
