I don't see anything wrong with having "things" like Radley suggested. As a matter of fact a lot of real amps nowadays have parameters/settings like those and it is an easier/faster way of achieving the tone you are looking for. If for example you want your tone to be spongier, fatter, bloomier, ... would not be cool to have knobs named with the effect they produce that interact with the advanced parameters in the background so you don't have to know anything about how amp works internally? (i.e. http://www.sfdamp.com/images/product/SigX_Front-Detail.jpg)
I have to say that I find very useful the voicing parameter in the Axe.
I'd much rather have the amps' controls be named and behave like their real-world counterparts. If that means you need to learn a bit more about the "guts" of any particular amp and how it operates, so be it. But I don't need to have that kind of specialized knowledge to get a great tone out of my Tweed Bassman, for instance, so I'm not sure why it'd be a necessity for other amps.
