If someone has already decided for themselves that all modelers sound bad, there's not really anything to talk about here. I've owned most of the PODs including the HD500, and been through many software plugins, and in my opinion, none are even playing the same game as the Axe FX II, much less being in the ballpark. You're not going to get real amplifier feel from the Axe FX, and that's what it seems like people are often complaining about. I don't understand because that's not it's intended function, and being a standalone preamp is only a possibility that's been designed into it. It's not an amp, so stop comparing it to them. If you were comparing the models to a recorded a processed guitar amplifier, that's a different story... and while that's not spot-on, it's convincing to thousands of people out there. The Axe FX is about what the audience hears, not what the guitarist feels.
It's a silly argument to see on every message board.
