Running my current favorite method of Amp+Load Box into the AxeFx, I have been A/B comparing my amps with the models and they are nigh on identical after adjusting the Impedance curve.
Switching between the JCM800 and the AxeFx model:
In 1: Instrument Input on the AxeFx.
In 2: from the JCM800+Suhr Reactive Load
Out 2: SPDIF output into my DAW, same IR.

@Orvillain, sell your AxeFx, you don't need it.
