Pro recording is going to sound like a pro commercial recording regardless of the gear used. Doesn't mean its always an ideal tone, as its subjective to what the artist/producer likes, but once its been mastered your really not going to be able to tell much, if anything, of if the tone is Axe, KPA, real amp etc.
As such, I'm not really sure what you can take away from listening to a recording done, or not done, with the Axe
