I fail to understand how people are getting such bad sounds out of a Kemper. I started this digital journey when the first Headrush came out and I thought it did a pretty good job but it did have its weak points. I then bought a Helix. I thought it was good as well but not better or worse than the Headrush (although the HR is much easier and faster in dialing in the sounds). When we started recording our first album, we were in a studio with the Kemper toaster and when I recorded with that and heard it back, it was significantly better than either of the other units I've tried. The engineer said he was using MBritt profiles and I was amazed. I went out and bought a Kemper Stage and used it for many years.
Of course like a typical equipment nerd, I had to see "what else is out there". I went through many different modelers and capture devices. I tried the Boss, the Atomic, Tonex, Nux Trident, Quad Cortex, and probably some others. I got a Fractal FM3 and added the FC6 controller to it about a month later. Out of all of these, I still have the Trident because it's a great grab and go solution that is built like a tank and it sounds really friggin' good. Out of all of them, for sound and feel, still nothing even touches the Kemper. I thought the QC was actually pretty good but it was not reliable AT ALL!!
Now I have the Kemper Player, I use the MBritt profiles and I added a simple two button switch to go through the rigs and it's the absolute best. Every single show we play the FOH people always compliment my tone and ask what amp I'm using. I now use just the FM3 for a backup rig though I've never had to break it out. I can use pretty much anything I want on stage. The Kemper just works every single time.
I know people are complaining about how old the technology is. It may be old but it's beautiful. Just like a 67 Deluxe Reverb or a 1982 Marshall JCM800, there's no need to change anything really. But with the Level 3 Player, there's not much I can't do and the sound is absolutely top notch.
All these other solutions are giggable and most are very recordable. But they are not a Kemper and they don't sound and feel as good as a Kemper. That's MY story and I'm sticking to it. We'll see what happens in the next 10 years but nothing that is out there so far is going to dethrone the champ. Best of luck to you all.
