I mic an amp the way I normally would to record it.
Then I feed that chain through the Kemper.
And we profile it.
Now I can push that button and compare the live sound through the mic’ed amp to the profile of the same thing.
And the differences are SO slight that everyone in the room can easily be confused as to which is which.
If you’re feeling your amps are clearly to you SO much “better” then something is plainly wrong.
But having said that, I’ll add that I do use some select profiles from other people.
But the vast majority of what I use are profiles I’ve made myself.
This is in no small part because I like my amps (and the friends’ amps I know I like) but even more because I like the way *I* mic and record them.
For example: When I set up my favourite AC30 and record it, that’s a sound that’s, oddly, almost nothing like every typical AC30 model and profile I’ve heard out there.
But the AC30 profiles I’ve made are indistinguishable from my amps.
It’s quite conceivable that to the people who made those profiles that I don’t much like, MY profile would sound ‘wrong’. Who knows?
But my experience tells me that although you can certainly poke about on rig exchange, or the internets in general, and find some useable profiles, the real key to Kemper happiness is to profile the sounds YOU know YOU like.
