What could possibly be said negative though? It's perfect.
The last firmware was so perfectly 100% accurate to real amps and if you think otherwise I'm going to insult you. But some drastic changes had to be made because it wasn't accurate at all, and now the entire sound has changed so update all your presets. But don't you worry, NOW the current firmware is perfectly accurate, if you think otherwise you're obviously a deaf moron. But don't worry, a major firmware release is coming soon which will fix all the inaccuracies it has.
