Is it the nice tweaking that you hear or really the new profiling 2.0? Because in the other video with the untweaked profile the dynamic response seems not as good. Or what do you think?
I'm just using my ears at this point, not very scientific. Also, dynamics are a product of both the guitar/amp and the player. I think you just need to wait to try it out to really know.
Have you tried playing around with Bright Cap Intensity on Mk1 yet? I have an unresolved thread where I have problems with Liquid profiling and low gain. I experienced in this context that reducing Bright Cap did compensate for a too spikey tone and the feel and respond on neck pickup was way better too. But it was not nailing the exact accurate amp tone anymore.
I accepted that the actual Kemper Mk I profiling sometimes sounds spot on. Sometimes close enough. Sometimes (with tweaking) different but alse very good.
I have not messed with bright caps and honestly, I do not really use liquid profiles. My main bands I'm in with the Kemper is two bands copying songs. In this case, I pick a profile that matches as best as possible for that song and so on and so on. I don't run the same amp all night and adjust things like gain and EQ.
I think it's important to remember Kemper doesn't have a "sound" per say (though some say it's a mid-heavy compressed sound, I'm not so sure) - the unit is as good or bad as the profile and recording gear used to do so. Use a garbage mic, get a garbage sound. For me, if my capture is too bright the easiest thing to do is move the mic farther off center until it's not.
As far as accuracy, it depends on the mic too. Mic's have an EQ curve to them and you can hear a difference between the amp and your profile just due to that. Add in preamps, cables, etc. it can definitely change things. Plus, you may think your amp is bright...until you move one foot to the left and now you want more high-end. If you're comparing a profile with in-ears to an amp sitting in the room with you, the proximity to that amp makes all the difference in how you hear it.
I know Michael Britt prefers his profiles with the Definition between 4.5 and 5.5. This allows you to add and remove as needed. I can also say that playing with the band, sometimes you want "unpleasant" highs to help you cut through. Just depends how the profile sounds in the mix.
Maybe the expectations are too big?
I don't think so but also remember, these are all digital devices trying to replicate analog tubes and guitar speakers. I'm not sure we'll ever have an "exact-exact-exact" replica of any amp. Tubes don't react in a 100% predicable way - they break up how they break up.
On top of that, it all depends how you are hearing your guitar tones from your Kemper. Studio monitors, power amps, cabinets, room acoustics, IEM, etc. these can all dramatically change what you're hearing. And again - playing through a live tube amp vs. a Kemper through in-ears...totally different experience.
A lot of people tune their profiles at low volumes and then get to a PA system and have to redo everything because volume changes how and what you hear.
Again, I would hold off judging 2.0 profiling after you have it in your hands. The comparisons are nice and honestly, I'm very happy to see progress on 2.0. But until you have it, you won't really know. It's like judging a tube amp from YouTube - you need to be in the room with it.
