My Journey,
So I get a Kemper in 2013, profile my amps, listen back and forth, and over the next year end up selling amps I thought I'd be buried with!
I then took a few years and spent $1000 buying commercial profiles and sifting for rubies in the clay of free profiles. For my money, always loved TAF profiles. (why? If I liked some famous sound, I'd research the guitar and amp, buy the guitar, find the TAF amp profile, and be able to reproduce the sound exactly. So that convinced me his engineering was on key replications for famous commercial sounds)
Of course I was always interested in "what else is out there". I'd sometimes I'd get an analog amp (ie trade gear and figure I could sell the amp for more than what I traded) and enjoyed the immediate "turn on, play" aspect (bc the Kemper took 45s to start. always has for me even if I have 1 profile on it.) Talk about impatient! And I'd build up a pedal board, and eventually sell or trade it all off. Plus, I'd play my friends digital amps. Often the Fractals. I owned an ULTRA before the KPA. And played the FXI and FXII. I thought they're amps were always a step lower and many of their effects a step up from Kemper, and for the FXII I still think the amps aren't as good, many KPA effects are as good, but I still like the FXII grid. Haven't played the FXIII yet. With the FXII XL+ I felt it was a fun box for people who love 80s rock, but otherwise, no one could do a 1955 Gibson amp better than Kemper.
Then I was playing live with some friends that I helped build a studio with (I'm more into studio gear than playing live. I write songs and record them, so I'm essentially a studio hound, not a live player, hence the Kemper is perfect) and bought some amps (64 Reverb HW & VOX AC15 HW, built some of my own (Fender 57, Marshall Bluesbreaker)
I have a favorite free profile of a VOX AC15 HW and so wanted the hardware, but the profile is better for me for some reason. I even got the OX box by UA and a KHE 4x4 to be able to switch all 4 amps between all 4 analog amps and can play them in headphones and record digitally now.
Then a friend wanted to sell his Fractal FX II XL+ so I got it for a good price ($700) and aim to connect that as a pedal board for my Kemper. Or use the Kemper as an Amp Block in the Fractal. Not sure yet. I love that Fractal 12x4 grid, it's so easy to manipulate. I did this originally with the Fractal ULTRA back in 2013 so I know it works well.
So now... I think I'll sell my pedals again down to 3-6, sell 2 of the commercial amps and keep the 2 I built and stay mostly digital for recording, and keep the 2 analog for rare live playing or practice when no one is home. It's less wires to bring the Fender 57 Deluxe than to take a Kemper & Cabinet. Plus the KPA is wired into the studio so I have a chore to rewire it all back if I grab & go.
One thing I've never done is sell the Kemper. I always find a good use for it on recordings. And I've played songs for guys who do swear by amps and they never go "man, your guitar amps sound fake" bc they dont'. But thats what $1000 journey with profiles nets you. The search and money whittle you down to the profiles you love.
I'm not interested in the FXIII until it's price comes down below $1000. IDK if I'd get a Kemper 2.0 if such a thing will exist, unless my current one dies. 11 years and no problems, knock-on-wood. And even then I think the only advantage for me would be if it had Wi-Fi like the Stage. Maybe also the ability to pickup Bluetooth so I could play along with music on my iPhone's Spotify? Ok, daydream over!
Kemper has been one of those boxes that checks what I needed for sounding professional on recordings with guitars. It's right up there with my vocal chain solution which is 10x more expensive (mine is UA 87ai -> BAE DMP -> WA-2A with NOS SONY tubes -> EQP-WA with NOS SONY tubes to UA Apollo 8p interface and rackmount digital reverbs. I also have a UA 6176 as backup for that chain. and a SM57/R122 pair for Acoustic) That vocal chain was the box checked for making vocals sound pro (plus UA's Lexicon 224 or 480L reverbs, like WOW plugins)
