It is hard to explain what I mean but maybe you experienced a similar thing:
The Kemper is perfect for strumming stuff. The sound itself is always perfect, yes, no complains about that.
But let me exaggerate to make clear what I mean: My problem occurs not only with slower solo playing and arpegiated stuff but especially when I play fast single notes - "technical stuff" with let's say a high gain Plexi profile (scales, arpegios, tapping) the expected response is not a hundred percent there while play. The Kemper does not react as expected (=tube amp), it seems to suck life from my playing and my fingers at every single note that I don't hit hard and clear enough. Does this make sense? The notes seem to die out much easier and faster than with my amps or even modellers. I have to hit the strings very much harder and play much more accurately to achieve a similar tonal result which can be disturbing while playing. The Kemper is not at all forgiving with sloppier playing or weakly hitting a note within a fast passage - the note will die out much more easier. So the amp feeling while playing is not realy there. I've tried with compressors, boosts etc. but this does not really fix it.
Does this make sense for you? Is it a mere "sustain issue"? Do I miss anything or have you experienced similar issues? How do you fix this?
Thanks
