Well, I forced myself to listen to all of this and finished up non-the-wiser! Possibly because I couldn\'t hear most of the commentary behind the constant guitar playing. Please tell me if I\'m thick, but I can\'t see the point behind the set-up. Can anyone explain what\'s going on? Ian Colley.

Hi Tex,
I agree - the guy playing the guitar was really annoying; he kept playing at completely unnecessary points in time (perhaps Dave thought it was really all about him?).
Also, I got the sense he didn\'t really understand the main point either - which was primarily about creating a profile of the original amplifier. The most important demonstration should have been that, after profiling, the sound should have been the same when switching between the Kemper amp and the original Tyler amp. That point was really lost in the racket he was making.
The other video is more helpful. Somewhere around 2:30 the explanation of how the process works is given. The following is what I inferred anyway:
You connect the Kemper to the original amp, the original amp drives the speaker cabinet. The speaker cabinet is mic\'ed up and the mic\' connects back to the Kemper.
The Kemper generates a set of reference signals into the original amp and analyses the result coming back from the microphone. Chris doesn\'t really make it clear whether it\'s also necessary to generate some signals by also playing the guitar into the loop (surely, otherwise why connect the guitar until after the profiling process). During that analysis, it calculates a set of key parameters for that sound that will be used in its own digital synthesis. Then I think it does some iterative looping, starting with that initial set of parameters, driving the original amp again, measuring the result, and refining the parameter value set.
By the time it is finished, it should be possible to plug in the guitar and switch between the original amp, and the output generated by the Kemper through the same speaker cabinet and the sound is, ideally, indistinguishable in each case. That is, you should be able to disconnect the original amp and use the Kemper instead and have an effective replica of the original.
Then, as they say, you could go on and fiddle the parameters determined by the Kemper - away from the original sound or, perhaps, to further fine tune it based on your own ear rather than just the smarts of the Kemper.
And, finally, there\'s the idea that you could download parameter profiles for any amp as created by other people doing the analysis using their own profiling amps, to effectively give you \"many amplifier models in one box.\"
That\'s my take anyway.

martin: you should be their public relations rep. you did a much better job of explaining it then mr. kemper did!
also, to me, the big plus would be that you could download other amps. otherwise you have to go around finding amps to record.
hopefully in the real world, it doesn\'t sound digital like the line6 equipment, which is much better than nothing, but still not the holy grail.
thanks for your explanation as it sure helped me! mikeB.

Imma gonna profile a Kemper Profiling Amp profiling a Kemper Profiling Amp.....Ad infinitum! Muahahahaha!
Brent Peterson
I wonderful if I could profile my voice? Then I could get other people to sing or talk for me and I could go on vacation!
Jamie Palmer
So now that I have this amazing and expensive device, I have two amps that sound exactly the same. Im lost, why buy something to recapture what you already had? You could have bought another amp altogether... Just saying

Jamie, I\'m sure it\'ll come loaded with a bunch of the classics (standard procedure these days), and any time you run into a great sounding amp at a jam or something...well, you can pretty much steal it. And tweak them all to taste. Seems like an excellent tool to have, especially if you\'re still looking for that tone in your head that is your voice.

Jamie, how about having all your rigs, other famous rigs, your friends\' rigs etc. on stage in one package ... or in your bedroom or at practice. that concept has some appeal

Hi Martin, Thanks for your detailed analysis, I\'m still not happy about how the information gained from using reference signals is meant to be used however, surely playing the unit in series/tandem with any other amplifier would introduce many other variables, so bringing you back to square one? I\'ll have to mull this all over and get back! Thanks again, Ian Colley [Tex].

Hello everyone But I think we\'re forgetting one small detail ... With what will reproduce the sound? Surely this device will work well for the profiling of the amplifier, but in order to listen in the best way, you should pay particular attention to the monitor used for playback ... It \'easy to conclude that not sound like a real amp simply is bad because we used the monitor ...
