Using Clean Sense setting with low level guitars.

This says it all and is what I was trying to say.

Quoted from "ckemper"
Ok, guys, here is the conclusion:

Everything works as expected.
As you know the Clean Sense will change the volume of clean sounds. This is for leveling them against distorted sounds.
Slightly distorted sounds WILL STILL be affected in volume by Clean Sense, since there is a certain TRANSITION window, not a hard distinction.
The smooth transition is needed, since there is a soft transition between clean, crunch and heavy distorted sounds as well.

The change you are perceiving is just a change in the output volume, not gain or something else.
The sound is not changed, just the volume.
And it has always been like that. We didn't change this since the release of the Profiler.

CK,
I get that you're thinking it's perceived volume that I'm talking about. Took your suggestion and tested that to make sure. In a sense you're right. But it has nothing to do with the Master or Headphone output.

So I started testing different input settings (no FX, no compression) with my P90's using the Kemper "Chief Dirty CU29" rig. Created a Zero input (0 Clean -0 Distort), Default input (5 Clean -0 Distort) and lastly my input (7.5 Clean -2.5 Distort). I switch between all three while playing an open chord.

I agree with you CK, IT'S NOT THE TONE that changes. But jacking up the Clean Sens increases the ratio (volume) of clean to distortion. I prefer more clean to grit. Seems to me it's the combined settings of Clean and Distort that make your guitar respond differently to your touch.

I think of it like a blend, threshold and balance control between clean and distortion. Now if I'm wrong about this please correct me. I'm only reporting what my ears tell me.

Clean Sense only affects the volume, not the tone or touch.
Of course, if you move Distorted Sense from the zero position, it will affect the amp gain, thus altering the touch.
