Check this raw amp clip out (not u2). Towards the beginning, the more driven sound makes it clear to me and even later on it's still evident in the cleaner sound.

I agree !
It wont get close enough .I tested a real one up against the axe the other day.
Those amps are funny. There is lots of hum from the psu being intermodulated
into the sound. There is also lots of pleasant and nasty overtones that doesn't seem
to be in the axe. The axe sounds a little to nice and lifeless compared.
It doesn't roar in that voxy way.
At least I think.
By the amp
What about cranking the Transformer drive, or turning the Transformer match?
