Having dabbled for many years with numerous digital 'pro' solutions for guitar and bass amplification, both in the hardware and software domain, I still found myself going back to the traditional way of recording guitars through micing up a proper rig when needing to 'push some air'.
Then the KPA was announced and raving user reports soon started pouring in throughout the internet. Users were saying that this new digital amp sounded equal to, and greatly surpassed the flexibility of, a professionally mic'd up guitar amp and cab. With a fair bit of scepticism involved, realizing this was still a new arrival on the scene and all those positive user reports could very well be a case of 'awesome brand new toy' syndrome, I bit the bullet and ordered one to try out for myself.
Upon receiving the unit, I upgraded the firmware and plugged in my Gibson. And I kept playing for hours. Damn, this was it! It actually felt like playing the real thing. The dynamics, tone and natural response from a real amp, but with unsurpassed flexibilty of shaping the final outcome.
I've been working with the KPA in my studio for more than a year now, both for recording and re-amping, and I'm positive I will never part with it unless there's an updated version I'll switch to in the future. Having said that, I'm not missing much at all. At times, there's a lot of menu diving due to the sheer possibilities of this thing, but a unit at this level of complexity, I'd say that Kemper has handled this as good as they can. I would love to see a software controller for increased overview of all the parameters and profiles available in the future, similar to the plugin controller of the Access Virus synth, but for now, I'm getting by just fine tweaking the unit itself and saving my creations in the Favourites 'folder' of the KPA, which makes browsing your current project tones a breeze.
Adding real pedals works as a charm, but is very dependent of what profile you're playing into, occasionally needing a bit of gain staging and proper think-through of the recording chain. Same goes when experimenting by switching around profiled amps with different cabs. When in need to play things safe, I just record both the 'amped' and the DI signal for possible future re-amping, which is easily set up and accomplished.
A very cool thing is the vast range of user created profiles, both free and commercial, that broadens the usability of the KPA to near-ridiculous proportions. Again, a software controller to organize and overview the unit's current profiles would be most welcome, but it still works as is. And, just like with the Access Virus, you get continuous official updates with added features, effects and content free of charge. It has become even better with time, and is without a doubt an integral part of my studio setup when it comes to recording and re-amping electric guitars and basses. It's fun as hell on synths too.
Buy it.
