Just have to say I am totally blown away by the sound quality of the profiles and effects. In addition the control layout/design is so well thought out. First time I have gotten a new piece of gear and basically been able to figure out all the functionality without needing a deep user manual/watching videos. As a result I am really inspired to play the guitar and I have spent minimal time tweaking the sound because I am getting exactly the sounds I want with a few minor tweaks/adding modules.
My first profile I played was a 2011 AC20 amp and it just immediately sounded good without even adjusting anything. So far I am really like the Matchless amps in normal profile mode and I like the Plexi liquid profile/tonestack too. I also was impressed by a lot of the profiles I found for free on the rig exchange. It was so quick to try new sounds/I pretty much knew immediately which ones would work for me. Grabbed some Tone Junkie free presets/effects as well that are great.
I think having spent 9 years deep diving with the Axe II may have been a great primer for being able to use the Kemper so easily, but nonetheless I am so stoked to have my Kemper. I will report back after the honeymoon period, but I am a guy who will return things instantly if I know they are not a good fit/I am so critical of what I need from my gear/sound.
Quick take away is that Kemper is the best of all the ones I have owned for sound and control. Fractal is still great for studio/recording, but Kemper actually feels like an amp in the room and doesn't require 100 parameters for each module. I know it will also shine in recordings/pair well with the Axe FX for multi tracking. Helix is my least favorite and the Boss is alright. I just have a weird disconnect when playing Helix, so the sound is not necessarily bad, just the response to my dynamics/feel is off.
