A thought about Amp Profiles:
I have perceived over my considerable time using the KPA that our favorite profiles are largely dictated by random chance as much as a great amp or mic. Some combinations provide great profiles, while others turn out very lackluster results. My faves tend to be the ones that don't have too much of that dreadful overbearing Marshall upper-mids peak, but sound more smooth and even across the audio spectrum. Even many clean profiles can do a better overdriven sound than the aforementioned over-hyped, cocked-wah nightmares...
Back to my original point - Producing a great profile would appear to be as much luck and blind chemistry as it is picking a great amp and mic...
