Kemper newbie here. Picked up a used PowerRack and Remote, coming from several variations of modellers and the like (Helix, Quilter, BluGuitar, Blackstar). I'm running my Kemper on a 1x12 that I'm very familiar with (love that wattage meter!). It's simply incredible sounding. Spent a lot of time in advance getting familiar with functional stuff, reading posts that I knew were related to my setup and live performance needs, watching videos, etc. Performed a complete factory reset after updating software to latest version. All of this BEFORE plugging and playing for the first time. It was difficult to resist, but I knew it was the best way to get my head around the basics. Also, had to fix a loose Remote connection at the network port (an awful design flaw/oversight, btw). Still doing a ton of research regarding nearly every Kemper topic as I progress through my favorites thus far.
I'm gigging 200+ shows a year, so a pretty heavy schedule. I've got a lot to manage and organize before the Kemper will be in my live setup. Don't want to rush the process, actually. Still gigging my current non-Kemper setup as a necessity (and it will remain a backup), but just did an A/B in my studio out of curiousity. You already know I'm going to say the Kemper is just superb. I have sorted 20 favorite profiles thusfar of various amps and, as with my process during comparison, I turned off all of the effects (particularly post FX: Mods/Reverb/Dly) so I could hear the amp dry and present on the cabinet. The profiles that I've favorited are simply a joy to play, so responsive and musical, and it is so unbelievably good on a proper guitar cabinet. Also, of the FX I have sampled, they are superb, too. Even digging that classic chorus "pedal" in a Pre position. Love the flexibility of the Stomps/Effects sections. I don't quite understand any complaints I've read about the FX. I'm currently running an H90 on my previous rig and have been through many of the top-shelf FX units. All I can add is that the Kemper holds it's own, very respectably, in the FX category. The seemless integration alone is a beautiful thing. The simple spring reverb, itself, is a beautiful thing. Sampling some of the otherworldly reverbs; they are inspiring to play, which IS the point of any piece of gear, right? Inspiration. Keep it coming Kemper.
I will dig in to navigating and balancing the FOH/monitor sound next. Already having a good handle on the many varied results of FOH/monitor feeds from other modeller type setups I've gigged with, I suspect the Kemper profiles will be amazing in that regard, as well.
I fully understand the longevity of this platform now; it's in a league of it's own, that "rare air" kind of stuff. AND, the community of profile creators - and you guys with solutions (or potential solutions) to nearly any issue - is a vast and extrememly valuable piece of the Kemper infrastructure this many years on. Anyway, I could ramble on, this love-fest, about how stunning it is, but you guys already know that. Very glad to be in the Kemperverse after so many years of being an observer. Really looking forward to it's professional use in my world. I'll be back for more answers and suggestions, for certain.
