Just received the 770....
My God, what a hernia maker. It's not bad enough that it weighs 105 lbs., but try maneuvering that box at the same time. A hand truck surely helps.

FedEx didn't destroy the exterior of the amp, but it did pop the staples on the bottom of the box. Thankfully, the strapping tape held.
Can't wait to test it out...if I can lift it into place..ughhh!
