I normally would not post a reply to a question like this, mainly because tone CAN be subjective, and so very personal. That said, I have made a fair number of profiles with a MK1 rack, and now have a MK2 rack. Disclaimer, I have not made many new profiles under 2.0 but I want to talk about a recent profiling session.
I profiled an old Line 6 Pod XT Pro. Again. I had attempted this under MK1 with not so favorable results. The profiled tone was very different to the original. And at the time, I felt it was just a limitation of the profiling nature of MK1. The MK 2 2.0 profiles of the same amp emulation, a Vox AC 30 top boost were startlingly different. The interesting thing about this experiment is that the source was exactly the same, the same patch, maybe the imput level to Kemper not scientifically exact, but that may have been the only outlier factor.
The result, the sound was way closer to the original, but also way less compressed and less dark. The gain range was way closer. Maybe the most important was that the resulting profile was more malleable, meaning I could take it in far more directions after the profiling was done. This alone offers some insight into the possibilities of the new 2.0 version. I want to mention that the process is easier now that refining is no longer a part of the profiling.
This particular sound is telling, it’s a dirt in between clean and overdrive, that place where many profiles go to test against the mountain of tone god, and most fail the climbing attempt. The thing about heavy distortion tones is that they are inherently more compressed by nature. This may be why those sounds still provide satisfaction having been profiled on pre 2.0 profiling. (let’s assume for the sake of argument there is no difference playing these in MK1 vs MK2 hardware, as I believe to be true)
One final point, when profiling a real amp, the basic amp tone, the mic placement, and the resulting editing of the sound in the kemper still play a very large part of the sound we experience. As a result, and IMHO only, profiling under 2.0 by itself is not the panacea, it is not the golden goose, it will not make a mediocre dialed in amp sound any better then the source can be. We still need to use skill, our ears and our creativity to create next level profiles under 2.0. That said, 2.0 opens up possibilities that were simply not available under the old 1.0 profiling. We have yet to reach it’s zenith. It will take time, and much hard work creating those next level profiles. The irony is that for some sounds, MK1 profiles that were very well executed may just find a place in the new paradigm.I guess that means - use your ears, and go with what works for you.
