Hi
So here is my story. Had many different amps throughout my career playing music. Bought a kemper a few years ago ,also had a Fractal unit went back to amps for awhile. I decided to give the Kemper another try since I regretted letting it go. Got set up and was running the kemper through a 2 12 cab using a Fryette power station. This rig sounded good but I continued to use my main amp a 50 EVH head a 2 12 cab with a few pedals. I was not happy with the Kemper running through a guitar cab so I thought what the hay plugged it into my PA system which consists of a nice board and very high end powered speakers. Had to do some minimal tweaking and low and behold found some great profiles some paid for, some free on the Kemper forum (BTW there are some amazing profiles on the rig exchange) and OMG the sea parted and the heavens opened up. Its bar none the best tones I've have ever gotten. And portable, I have my Kemper , pedalboard and powered speaker if I so choose to use one or just run direct into to a PA. I even have a smaller rig than my bass player lol and it sounds so good. Even a friend of mine who owns an Fractal says the Kemper cab sims are amazing compared to the Fractal's which is his words are crap.(he uses a better di for his tones) Since I also run a guitar synth and also use a piezo system I'm used to the sound of FRFR so the adjustment wasn't that hard but now going back to a regular guitar amp system some of the tones I'm used to hearing on the kemper aren't there.
Anyway couldn't be happier and I highly recommend the Kemper to anyone looking for stellar guitar tones.
