update:
Now, a few weeks later I wanted to share my experiences with my new toy:
After dialing in my tone/sounds by going through all the rigs that came
with it + newly purchased commercial rigs (by Guidorist, MBritt, GoT) on
headphones I went to my rehearsal room to check them with my 1x12
cabinet (Celestion Gold). Me and my fellow guitarist did some
comparisson (KPA vs real Amp, in this case a Fender Princeton).
First of all: Yes, the real amp "behaves" and sounds different. Period!
Is this conclusion important to me? Nope, not at all.
The sounds and feel I get from the KPA is just great and fullfills my
needs, that are having different amps available with a flick of a switch
(on my Remote) and all sound great.
Next was 2 rehearsals with 2 different bands, mostly classic rock/soul stuff, covers only:
Both went great, the second was extraordinary cool, all members loved my sound(s)!!!
Then it was time for stage!
1. the transportation and setup on stage was a blast, no 4cm, no 1000s of cables ect...
2. Setting up my inear delivered (almost) the sound as you would expect by using headphones
3. I never sounded better, my tones cut through... great!
What I learned: Yes, there´s some fine-tuning to do for sure. Maily volume adjustments
I will programm dedicated rigs for each of my guitars, maily LP, Strat and Tele
I will also programm some rigs dedicated to specific songs (e.g. Hotel California and a few others)
I will keep my analog stuff for a while but chances are big that I may never return to it!
Due to the so so easy dialing-in compared to my Axe FX II I plan on
selling it and purchasing a rack version KPA for my home studio...
