Awesome! We have the same setup! Rev 2 & Rev F... Two of the greatest amps ever, IMO. What serial number is your Rev F? Is your uberkab v30s or a mix with g12t-75? Which of the cabs sounds better with either amp?
Love the sound of my Engl and my Mesa together! I really liked the Fireball 60 when I had one too, ended up trading it for my vht though, so no regrets on that one.
