Also: if i use a MBritt profile of a Marshall and you use the same profile we have the same tone. We sound different because the player is different but the basic fundamentals of the tone are there. If i use a Marshall OF THE SAME KIND as somebody else we will sound different: Because no two amps are alike because there are a lot of factors that come into play: Tube age, component values etc etc
Another: With the Kemper it's easy to get a decent sound, but it totally removes (as i feel about it at least) the craftsmanship of getting tones and sounds true to YOUR identity. So the amps you choose with the mics you choose and the cabs etc etc and then GETTING a good sound which is a craft!
If you want to have your own sound and also want to keep the process of getting your sound a craft, try to create your own profiles!
