I borrowed a Kemper for 3 days and my reactions are;
* 3 of all the included amps sounded fine (one of them great) and they were all profiles of 5150 amps... I know this is subjective, but that's my opinion.
* The profiler didn't make an exact copy of the Engl e430 I was trying out. The profile had a similar EQ but a different "character"... More clonky, less bass, less treble, more mid, I think... And yeah I did the profiling by the book including the refining stage.
* There was some high frequency "digital fnizz" on my favorite profile (TAF Van \m/ Halen)
EDIT ON THIS ONE; I backed off the gain just a notch and it was gone.
I can afford the Kemper, no problem with that. But do I really need it? I like my Engl, but I would like another amp sound or two for my home studio as well (even tho I record mostly the same type of shit all the time anyway)
Would I be better off just getting a EVH 5150 III since I obviously love that tone???
I cannot record at high volumes at home, so I would probably need some "hot plate" or something like that also... Hmmm...
I'd get an amp and something like a Torpedo Reload or Torpedo Live to allow quiet recording and even cabinet emulation. I like using tube amps with cabinet sims as cabinet sims can be awesome but I've never like amp sims.
