I know people are going to disagree, but does the Amp block really need more parameters? I can appreciate what Cliff is trying to do; giving control to the user to make the Axe as versatile a unit as possible is awesome. The trouble is that after a certain point there's pretty serious diminishing returns, if not even a negative impact/perception overall. How many reviews or forum posts have we seen where people were put off because they couldn't traverse the learning curve? A good portion on this forum's traffic is people trying to help with exactly that, or defending the Axe against someone who thinks it sucks because they haven't managed to figure out all of the intricacies yet. Not too long ago I got bent about a fairly high profile review calling the Axe’s advanced editing parameters esoteric, but to be honest the more I thought about it the more I realized some of it really is. I'd be pretty confident in saying that anyone who doesn't like the Axe just hasn't turned the right knobs yet, and I think many (here especially) would agree. Adding more variables is not going to help that. Making the unit sound better overall with no magic parameter knowledge needed will. At the time of writing this 87% of users think the "more accurate" modeling sounds better. Why add a setting to undo that? I know that adding one more knob isn't going to make it significantly more complicated, but why invest the time at all? You can't please all the people all the time, and the harder you try the less people you end up pleasing.
I know that there are some hard core fans out there who will happily spend weeks dialing in the perfect tone, but they really are a minority. I spent quite a few years working at a music store and I can tell you from experience that the majority of musicians don't want this (whether they come out and say it or not). The most often given reason for returning a product like a TriAxis, Eclipse, Command 8, etc. is because "it just sucks man". You don't have to dig much to figure out that they just didn't understand it, got frustrated, and gave up. Are those products for everyone? No, of course not. But I’d be willing to bet most here have been frustrated by the complexity at one point or another. I love my Axe and would never give it up, but I can honestly say that there's been a few times I've wished I still had my amp so I could just turn a dial and play without needing to spend hours programming the sound I want.
Sorry for the rant. My point is just that if an overwhelming majority of people think the new development is a move in the right direction, it seems like unnecessary complexity to add another parameter to turn it off. Like Soultrash said, it seems like a step back.
In some ways it reminds me of the Turbo button on my 386
