Thanks for that.
I am still wondering about the accuracy or not of the Kemper drive emulations/profiles. I am enjoying how they sound as I am not a player who likes the full throated roar of full on amp overdrive. I am more Robben Ford and Larry Carlton soundwise, although sadly not playing wise.
Yes and no and does it matter?
I'll explain....
The settings have been based upon hardware versions of the Klon and Bluesbreaker, but there are many other variables that effect how these types of devices work. So under the same set up, they should sound very close.
Does it matter? If it sounds good, does it matter if they are accurate? Unless you want to directly replace one, its less important.
