I still live with my tube amps AND the KPA. For some reasons a combo and a stompbox is still the better solution, when transport is an issue or entering a stage and being play-ready in 2 minutes (f.e. club sessions).
And though I own my KPA for one and a half year, I don't yet find myself at the end of my soundsearch at all. It's sometimes still much confusing for me which of the numerous parameters is the best to make a sound more transparent or fatter or smoother or or or (Amp-EQ, Cab-EQ, Slot-EQ, Stomp-EQ, Output-EQ and some more ) and when the sound is o.k. the volume must be matched, and again we have (Output volume, Cab-Volume, Amp-volume, Stomp-volume, and the clipping LEDs
So I think it's a long process which also makes you listening more careful to your guitar, identifying the right parameter in the KPA, and choosing the least necessary features to achieve your sound-idea. For me the shortest way is the best, so I choose only profiles which already fit to 80% of my needs), but I'm still very far away of this goal.
To cut things short: Despite of all these things.....
I'm happy
