You have one of the finest amp ever made, be ready to have a ton of beautiful sounds with this machine, i've got one (the head version), and since then i've never played something else ! congrats !!!
Congrats on the amp. I've had my MkIV head since '92, and I still love it. Rhythm 2 is voiced a bit dark for my liking, but they wanted it to sound like AC/DC's Marshalls apparently.
