I've mentioned this before, and it isn't knocking Kemper at all - as I love him. (Don't know why I see Kemper as a dude...like a cool brother or something...definitely not a weird uncle)
Anyway, when I play my real amps in rehearsal, I just think about playing and nothing else. It's guitar > wah > amp. A carbon copy for solos with the mix at about 10% is as extravagant as it gets.
But when I play Colin the Kemper, I am constantly thinking 'should I dip 5k by 1db or is the stereo spread of my delay too narrow or could I do with a little more pick definition on this solo'...and it is a little distracting, but I can't stop myself. First world problem for sure.
I do know however that Kemper is the most amp like of all 'non-amps' in terms of making changes...and if I had some ridiculous tweak machine like Helix or Axe...I wouldn't ever get to the point of playing a single note as I'd be too busy clicking things with my mouse and reorganising amp and effects blocks and routing nonsense like that!
And THAT, is the only reason Kemper hasn't cured my GAS for amp heads...not the sound of my guitar heads....but my actual stupid overactive head.
