Kemper Profiling Amplifier Rack BK

19" Guitar Preamp

Since the advent of modelling technology in the guitar amplifier world, guitarists have been able to access a variety of sounds and effects with relatively little effort.

But what if you want to take your own favorite sounds instead of the manufacturer's sound specifications? Prior to the release of the Kemper Profiling Amp, there were not many alternatives: either, as before the digital revolution, they dragged their entire equipment from place to place, or tried to adapt the modelled sounds of the modelling amp as far as possible to their own desires.

Kemper breaks new ground here. Instead of using predefined emulation of different amplifier models, the Profiling Amp (Nomen est Omen) creates an exact image of the sound set on the amplifier together with the connected speaker and microphone. This combines all the personal favorite sounds in one device. In addition, the sound profile can be edited with various floor effect emulations, master effects, equalizer, and so on. A separate amp fleet is not a mandatory requirement, because the Profiling Amplifier is already equipped with a large number of classic amplifier profiles. In addition, a large Kemper community has now established itself in the world where sound profiles are exchanged over the Internet.

Kemper is an excellent complement to boutique amps, and beats AxeFx2 for amps

Anthony3107, 30.01.2014
For my cleaner, plainer amp sounds, I have only ever found/tweaked a few clean patches I really liked on my AxeFx2, and nothing that every felt/sounded much like my favourites: my Dc30 or Ceriatone BM (John Mayer Type Dumble clone)

However, Straight away, on day one with the Kemper, from the free shared KPA patch database online, I have patches that are close enough to these 2 for me to enjoy. Certainly at present, simpler cleaner patches with a lot of amp feel that I would often use are more plentiful on this KPA

I was not initially too impressed with the factory-supplied cleaner or metal/rock sounds on the KPA, and the FX are a bit fiddly from the control panel (although that is compared to the dedicated main controls - volume and EQ - still easier than the AF2). Having the dedicated Bass/mid/treble/presence is such a pleasant change, along with the input gain and volume controls

As I said, the sounds I was looking for were available on day 1 with the KPA (not from the KPA-stock rigs though). The Thomann USB stick had a lot of very good sounds, the free Lasse Lammert Signature Rig Pack is exceptionally good for rock and metal, and the KPA forum has quite a few good ones. I went to specialist profiling suppliers for more ones, you can find a few online

KPA is not as heavy or solid as the AF2. Who cares though, it lives in a rack
KPA has no fan - what a relief, the AxeFx2 fan is very noisy
KPA does not try to blow your speakers when you power off if you forget to mute it first - the AF2 does create a big pop
The AxeFx2 FX are way better (delays and reverbs, pitch, etc), the PC.Mac based AF2 editor is better than using the front panel, making routing etc easy on the AF2, in comparison, the KPA is very simple and inflexible
The KPA deals with different guitars & pickups better (using the clean sense control, and the always-enabled input gain knob etc)

Overall I feel much more like I am playing and hearing a guitar amp with the Kemper, it is perfect for recording. For more ambient and effect-driven sounds, the AxeFx2 would be better

Best piece of guitar equipment i've ever used!!

Ian141, 07.11.2015
I've been a valve amp man for over 15 years and thought i'd never stray from my Mesas and Diezels, but as i've got older it's not as easy to 1) Carry all that around to gigs, rehearsals 2) Jam or record without waking or annoying my kids or the neighbours.

The Kemper seemed like the perfect solution, and so it is. The sound quality is outstanding, truely outstanding. Yes i may take you a while to find your way around it, but once you've got things dialed in the way you want you'll not hear any difference from the real thing to the Kemper. I've profiled and bought some great profiles of my favourite amps, and every one sounds incredible and if it doesn't try it with a different cab or pop some eq on it. The options are soooo vast.

The layout is fairly straight forward, and adding effects to profiles is soo easy. With independent buttons for each effect you choose. Want some delay? Tap it in with the tap tempo button then set your mix level and save. It's as easy as that. Having owned a Mesa Dual Rectifier and Diezel Herbert, the profiles you can get are soo close you'll think you are playing the real thing.

I got the non powered rack head, and its super light. Accompanied by a Thomann rack it's bomb proof and soo much lighter to carry to gigs and rehearsal.

This is the best piece of guitar equipment i've ever owned, and the pros that are dumping their big heads and cabs for a Kemper are testimony to this.

Don't think about it, do it, and buy it from Thomann...obviously.
