Interesting. Maybe there was something wrong with the unit I tested at GC. On a thread over at the FDP Forum we've been discussing the Champ. MadMos replied to my post that he tested the 600 with a 4x12 cab, and it was much louder, leading us to believe that the speaker Fender has chosen just isn't very efficient. The amp still farted with the 4x12, so I'm thinking that the power supply caps need to be beefed up.
