It seems modelers are always updating algorithms to get closer and closer to the amp they're trying to emulate. The KPA creates a copy of the amp (more or less) although at one setting.
You're pretty much there. The only thing I could see getting updated is a way to take one profile and it sounds authentic for all gain levels. (If you take a clean or slightly over driven profile then increase the Gain knob, it sounds fake the more it increases). This is why I'd rather take a higher gain profile and reduce the gain (using either the Gain knob or reducing guitar volume). It sounds more natural to me.
I just hope no matter what its backwards compatible with existing profiles , Every other company has failed me on this and its pretty disappointing to create a tone on an older unit and be told oh the new one is better , but you cant keep that tone you saved , you have to start over ! Ugh
So PLEASEEEE kemper if you do upgrade hardware have pity on us and let us use our existing profiles also !!!
