I'm having some trouble with profiling and I was hoping someone could give me some pointers on how to improve.
My main issue is that the low-end doesn't sound right at all. The Kemper sounds high-passed and palm mutes don't translate well. I also noticed that right after profiling, the Kemper profile is noticably quieter than the reference amp signal. After refining, they are closer in level but during refining I can basically hear the mids getting louder but the low-end seems to stay put.
I made a few samples where I'm switching back and forth - Kemper first, then reference - to show what I mean (tuned in drop C so I could play with one hand - I normally play in D). First up is my JCM800 -> Mesa cab -> single SM57. As you will notice, right after profiling the difference is quite big between the Kemper and the reference. After refining it's much closer, but pay attention to the low-end:

Next is my Orange Dual Terror, and here is where I really can't get it to work properly. Right after profiling, the difference in level is very noticable. After refining, again it's much closer but the low-end is just so much weaker. It also breaks up in a very different way, kind of "uniform" vs "non-linear" in lack of a better description.

I've tried a few things already. Tried with an external mic-pre, tried with mic directly into the Kemper. Same result. Tried changing a few parameters in the "Amplifier" section of the stack to make it break up better but couldn't get it closer. Tried adding some bass in the tone stack but it's not the same; the palm mutes don't react the same either way.
Any tips on what more I can try to get closer? Especially with the Orange amp - or is that one just really difficult to profile?
