Hi everyone. I want share and ask suggestion for an interesting try i made on late days. I tried a quick search on the forum for see if this question was yet made without results, so forgive me if this a sort of double post of a similar discussion.
After a abundant year with my Kemper Amp and a full range usage, i'm doing some trying with real guitar cabs and solid state amplification. Results is very good indeed, but i notice (i noticed even a year ago, but it was not searching in that direction) a missing part in overtone and harmonics.
So i did this experiment. I profile a guitar head (a Cicognani Brutus, a modern sounding italian tube amp) with a di box without cab. The Kemper Amp can profile the whole chain, and you can turn off even the cab, but how be sure or "measure" if the amp alone is profiled in a right way? My suppose was than if i can reproduce the di box tone, with a good linear power stage i can afford a very similar head reaction.
The result (better avoid long posts with my horrible english!) is no. The overall very high range of harmonics (those who kill your ears) of a direct head profiled without cab cannot be profiled. I tried to re equalize, various try, various volumes. But this part of frequencies in the profiled amp are missing, and this make sense as even without headphone i can distinguish in my guitar cab the Kemper Amp and was darker and empty on the harmonics side. Obviously i tried before a common profiling with a cab connected to the head, and turning off the cab i miss the same harmonics i'm talking about.
I find even some strange behavior (you can turn off cab or amp in the reference amp tone? how i can turn off something in an external real amp??). But the final meaning of my try was: can i simply have a valid substitution of an head not for record (this is out of doubt, the Kemper can achieve any micced tone in a great way) but for "in your face" usage? I'm not really interested at all to make a Vox play like a Dual Rectifier, this is acoustically not possible, but my question (and need) is if i can realistically can substitute with Kemper + linear amp a real head for use with a cab.
I'm very curios to read your opinions and your suggestions, or if someone has tried and maybe solved (i'm doing something wrong?) this need or is someway this feature is planned as a future feature (the no cab profiling, maybe in the same screen of distorted-clean profiling screen).
