I think that you would need to test something like Volume -5 (slot 1) / 0 (slot 2)
The fix was about getting rid of the automatic volume compensation effect. And in relese notes it has sais to be implemented below zero region "changed: automatic amp volume compensation in combination with distortion effects, which have volume set below zero".
Here was was older demo musicmad did where the problem is visible. Instead of the rig cleaning up and getting lower in the volume with sub-zero volume settings it instead put out pretty much even output due to leveling automation that was compensating the drive pedal as well.
Indeed. I gave it another try:
Works more intuitively for me this way at least.
Do notice that with higher KD definition settings, putting the amp gain towards 0 almost silences the tone, since the KD definition really thins out clean signals. Not sure if this is new though - just took me by surprise.
