I'd seriously recommend at least looking into a AD200b. They are beastly amps. Right amount of power and a good drive tone. Can be fat and clean or fat and overdriven.
I used to own a 400+ and the headroom on it is astonishing, so much so that it never got turned up past like 2 or 3 on the master..
Which do I prefer? The orange. I like the breakup you get and the rich lows, plus the power is more in my ballpark given the shows I play.
