What's the TLDR on a Kemper in 2023? Is it worth it? Why would you buy an unpowered over a powered, or a stage over either of those?
Kemper (and Fractal) are the two modelers that I haven't tried and my name hasn't been called yet on the FM3 list. Kemper may get some love from me.
I have a Stage and it is great.
I think I prefer profiles/captures over modeling most of the time because I don’t waste time exploring the minutiae of tweaking every possible component of the signal chain. You can easily find great profiles and set up a group of them in what Kemper calls Performances, easy to set up and very useful.
Some people are the opposite, they need the options to tweak everything down to the impedance curve of the power amp stage.
I find I treat the Kemper like an amp and pedal board that can instantly become another amp with same or different pedals. I play more music that way.
I invariably treat the Fractal as a sound design laboratory. Great fun but it distracts me every time my mind conjures up some possible tweak I could make.
The layout of the Stage makes it superior for spontaneous use. You can quickly get to all the parameters in an intuitive manner, it completely out shines the FM9 when you don’t have the editors in use. With editors they are pretty much equally great to use.
The whole signal chain on the Stage is always there on top. And it is like a giant tactile hardware version of a ‘touch screen’. For example touch a delay block button and that delay appears on the screen with its parameters labeled at the knobs. Yes the actual LCD screen part is small but it is easy to see in any light or dark stage or room… sunlight, spot light etc etc. However, since each effect block, amp, cab, input, output block etc has an illuminated button showing you the complete signal path with their status apparent the ‘Screen’ is actually much bigger once you start to look at it that way. Once I realized that I fell in love and my FM9 is currently gathering dust.
Kemper Kab is a unique solution. Powered Kemper Kab would be my preference but I couldn’t find powered version when I got mine so I use SD 170’s to power them.
it like the Stage is made for playing in a band, a performance, rehearsal, etc
the Fractal stuff is best when connected to a computer in a studio environment when you have time to explore the possibilitie.
in my mind they both sound amazing So flip a coin if realism is your main concern.
