Try the "Pure Boost", instead of adding a distortion.
BUT - The amount of Gain in an un-edited profile is the same amount of gain as the real amp, when it was profiled.
If you add MORE gain than the original amp had, the Kemper is adding the gain. This does not always sound the same as turnning up the gain on the original amp.
i am really a gainiac haha...but gain at 10 is way much too much imo
About 8 is most times enough (for some others still too much) sometimes about 9....
But when your Rigs with gain at 10 for you dont have enough gain...than try in the inputsection increasing distortion sense.
How is your input lead lightning? Always green? Sometimes Orange? More?
If always green..and never orange...try also more clean sense
and keep in mind...that the Highgain you listening on records in 95% of the cases is boosted with a Tubescreamer...especially with a Rectifier.
A Rectifier without a tubscreamer is not tight enough and very fuzzy especially when you record it.
Maybe because of that it feels not right for you. Its all about how to use a tubescreamer..some overuse it imo
"yes the color is usually green tipping into orange"
That is a good setting. No need to drive it into the red.
Pure Boost is one of the available effects.
If you want to use it for more Gain, you can assign it to slot A, B, C, or D.
im not a big fan of the green scream in the kemper compared to the original one...but i like it with the following setting:
Drive 0, Ton - 2,5, volume +2
the pure boost will only boost, but will not tighten up the gain..but maybe that one will work for you too
Since the Tubescreamer is part of the typical recorded tone for the Rectifier, Deadlightstudio's suggestion will get you closer to the kind of sound you are probably looking for.
show me some tone you are after...some clip of a song or so 
You got it Lars
thanks both of you
im going to start dialing in now
I also think searching via the RM for rigs natively gifted with the amount of gain you like might lead you to something.
yes you can add in the search function +....each + leads to more gain
so search something like +++++++++ (and so on ^^)
Or, you can sort by Gain in RM.

If you tried your original TS again, I am sure you wouln'd hear a difference.
i really tried often, with that setting i like the green scream, but my maxon 808 sounds different. Maybe the green scream is more a Ts9?
I think the green scream is very close to my tube screamer (modified with THE chip). My biggest gripe with a tube screamer is that it's not completely transparent as it tends to roll off some low end. The green scream is the same.
I have a virtual sound Jekyll an Hyde and it's completely transparent. With the gain on 0, love using it to tighten up high gain amp tones. I played around with the green scream, and can get nearly the same results just by dialing back the tone to about 8 or 9 am

... which is one the BIGGEST benefits of a TS, i.e. tightening the low-end
I loved TS-808's in front of my Mesa's, haven't played with the KPS TS's yet, haven't needed too, I just a Pure Booster in and get the added gain with no tone change. The OP might also want to check in the Amp section of his profiles he wants more gain out of, if there's any Clarity added to the profile, try removing it and see if that helps. Clarity kind of puts the gain more to the forefront. Experiment with it, you may like what it does.
