1- It IS like a tube amp. Feel, tone, dynamics, guts...out of the weight is everything there
2- Tweaking is dead easy and absolutely impressive, you can get ANY profile to your personal sweet spot. The range and effectiveness of the controls are far beyond imagination
3- I now spend 98% of my time playing, not tweaking.
4- The FXs are absolutely underestimated, the quality is top class.
5- I love to see the jaw-dropping effect on all of my buddies trying the KPA for the first time!!!
6- Profile sharing is highly addictive, every day you get some new toy to play around
Have been playing on backing tracks for 3 hours this night, randomly changing Rigs..and it was amazing how my playing was adapting to the tone, paying attention to touch, dynamic, feel, vibrato...hell, this stuff is really magic, Christoph was not kidding when he spoke about "Digital Alchemy"
