Yes, i like the paramater with the Kemper compressor and this help to tweek. But the external pedal like the Ego, Keely, etc. have this vibe that i cannot reproduce with the Kemper compressor stomp or amp block.
My best success so far has been a combination of a compressor in the A slot, a compressor in the X slot and some compression in the amp block.
Having said that, I still haven't managed to get that little extra something I get when I use a good external analog compressor.
Next, I'll probably get an Origin Effects Cali76
