Maybe it would be possible to return the modeling choices we had quite a few FWs ago ("ideal", "smooth", "ideal/smooth" etc.)?
I think (nothing personal) that this would be silliness and really missing the plot of the what the Axe was conceived to be, the most accurate emulation of specific amp models on the market.
I don't think it makes sense to try to be all things to all people. Cliff has a specific vision of the ultimate accuracy and that has what he has been working tirelessly to achieve. If some people don't like, frankly....too bad for them.
No one has to update after all. If someone doesn't want an accurate model and instead wants an idealized version there are plenty of other options on the market. To each is or her own, I'm certainly not saying those people are wrong in what they want, there is certainly something to be said for that.
At the same time, Cliff can't reach his goal, and seemingly the goal of the majority, if he's being pulled in multiple directions. Every time he has to stop and try to include old models, backwards options etc, its time that he's not working on moving forward.
2 steps forward, 1 step back isn't really practical. It should (IMO) be full speed ahead. Get on the bus, or get off if you don't like it. Cliff's way or don't update. He's got great taste, great ears and is smarter than all of us combined. I 100% will follow his lead as to what sounds "better". He's never let me down or steered me wrong since I've owned the unit.
The Axe should be a magic black box with the most accurate reproductions of nearly every amp on the planet. That should be its claim to fame and what it does better than anything.
Not everyone wants that type of collection though, some people probably are happy to just have a couple of somewhat generic amp models that sound good. For those folks, maybe something like AMplifire is a better option, certainly a cheaper one.
The Axe should be (again IMO) a collection of accurate amp models, warts and all, for players who really want to appreciate all those subtle differences and the "warts". If a real world amp is fizzy and harsh, the model should be too.
