Just got one of those new Atomic Amplifire 6.
Sound as good as (dare to say maybe better!?) my previous AX8.
It's definitely less powerful and featured but it sounds pretty good, specially edge of break-up - something it took me a huge amount of time to get it right before. It also has headphone out + gapless preset changing.
FXs are nothing as comprehensive as the AX8 obviously but I'm actually enjoying the simplicity..
One of the best things: it fits on my gigbag!
