Just thought I would pass on my Effects settings that I find substantially improves the playability of the Kemper at home volumes or thru headphones (for me anyway)
In the Output menu I have Pure Cab on at 8.1 and Space at 0
In X slot I have a Pure Boost set to 1.5
In Mod slot I have Space at 8.2
In Delay slot I have Analog Delay with Mix at 77%, Time at 610ms, Ratio at 4.1, Feedback 34%, Centre Freq at +2.1, Mod at 5.6 and Ducking at +0.8
In the Reverb slot I have Large Room with Mix at 35%, Time 6.8, Damp 6.9, predelay 160ms
I'm playing thru a set of Dynaudio Studio monitors and for me it makes any profile clean or dirty sound great.
Hope this helps someone
cheers
