I found a profile with less mids issue. After trying thousands of profiles (even paying for some commercial packs) i stick with one profile for my main gainy rhythm tone, and i only use another profile for clean to crunch tone with my band, i tweak both profiles depending the song-gain-fx's.
This profile is the XTC PLEXI BLUE 2 ANAL by maizin you can find in rig exchange. Equalized for even more mids and gain up to 6.9 for juicy and organic metal tone, versatile. (Yes, metal, but i hate all reampzone, sinmix, and similar extreme and scooped tones). Apart from these i can recommend mbritt cranckngo, cililab, and tonejunkie. They have free demo profiles.
Recently i have been a/bing between a lot of profiles with my ironheart 60w. I always use a 2x12 v30 cab. There was always more richness in the mids with the ironheart, even compared to one profile I made using the loop send of this head. This mids issue make the profiles more similar through a cab and less defined. I also notice a weaker attack with the kemper, with tubes i hear like a clean transient even with tons of gain, and that makes also a better note definition.
Maybe is an issue with my kemper.
I think the kemper is the best option, but it makes its best using the line output, for recording or PA, but i can,t get used to the frfr monitor sound in a full band live, i don't have a high quality monitor, but i am not sure it will make the difference.
Soon i will profile some amps in a studio and then i will be able to judge if the mids issue or any possible difference is negligible or not, but i suspect this way (through studio monitors) in a mix is where the kemper shines.
I recently DI-profiled my blackstar ht-5 and the mids weakness was slightly there (maybe is a DI fault).
Maybe my ears are blown, some people recomend more bass and treble in profiles buy i always need more mids or filtering bass and treble.
