Hey guys.
maybe I could help you out or at least point you in the right direction. I still think that the STl Tones are great source tones. But as always
You have to push it a bit further. I've added a screenshot. These are the major EQ tweeks which you can try to implement in your kemper via EQ sections.
First:
Search for the low resonance and get rid of it. It is always a different frequency, depending on the guitar you use. Sweep with a high Q beween 150Hz and 230Hz or even higher.
Once you got rid of it you should have a much more clearer tone.
Also look for higher resonances. Also seen in the EQ.
The agression was introduced with the SSL EQ. I always boost in the range of 1,5kHz for that mid range djent tone. (You can achieve this via Kemper EQ also)
At least I boosted a little more with a highshelf which should be easily done with the high or presence knob on the kemper.
Hope I could point you in the right direction.
Goodbye!
PS I made the videos on YouTube.
