Axe-Master
The AxeFX already has input gain parameters. This would just be a way to provide some automated help in setting that gain. This feature has been done in other products, so this has already been demonstrated to be useful. Anyway, as an optional feature, it wouldn't take anything away from how the AxeFX currently works, so you wouldn't be losing anything. After all, the whole point of a digital modeler is to provide flexibility that can't be achieved with a tube amp.
