Whenever I feel there's a lack of punch, I turn down the gain and just ram that pick into the same territory that I had before. I've never dealt with a Kemper, but I do use Overloud's TH2 when the timing calls for it, more often than not recently. I usually do put an analog preamp signal in and simply use it for the lower volume and the cab simulation(the George Lynch cab is really good, actually). If I had any critique, or it was my mix, I'd reduce the overall guitars by 1.5-2db and boost a hair in the 1.3Khz range, but.... tastes vary and I did appreciate how solid your tone was as it was shared in the original clip. It's always a struggle when mixing to not fiddle some more.. and a little more.... and then a little more... That being said, I'm also adjusting to new monitors on a new desk in a new room, so take it all with a grain of salt and best wishes.
