Hey guys,
Let me preface this: I am not here to troll, defame, or denigrate the profiler in anyway. As a tool, it's just amazing and I do really love it.
Having said that, there is a long standing issue that I am having with it, going all the way back to firmware 2.6 at least. So either I'm doing something wrong (my preferred outcome!) or the Kemper could do with a little more accuracy in this area - and it's to do with palm mute frequency response. Generally I am happy when playing clean tones, and I cannot really distinguish between the reference amp and the profile. But when it comes to palm muted metal or hard-rock passages, I can very often tell the difference, even if I cannot specifically pick the Kemper.
The amp is a Fryette Sig X, but I've had the same experience with other amps, namely a Diezel D-Moll and a Laney VH100R. The cab is an Egnater Tourmaster 4x12 with v30's. So it's not amp specific. I've used the same guitar in all cases, which is a Orville Les Paul Custom with Seymour Duncan Distortions set - the SH6's.
I've done some recordings that I want to walk you through:
Set A:
https://drive.google.com/folderview?id=…Wjg&usp=sharing
ReferenceAmp.wav - Recording of the reference amp.
PreRefine.wav - the profile before any refining has been done.
PostRefine_3Minutes playing.wav - I wanted to see if the length of the refine period made much difference. It didn't seem to.
Set B:

ReferenceAmp.wav - Recording of the reference amp.
PreRefine.wav - the profile before any refining has been done.
PostRefine_SameSettings.wav - Leaving the amp at the same settings, I refined the profile.
PostRefine_LowerDepth.wav - I then used the undo feature to remove the refinements. I then turned the poweramp depth down on the amp to reduce the low-end coming from the cab, and then did another refine stage.
Set C:

ReferenceAmp.wav - Recording of the reference amp.
PreRefine.wav - the profile before any refining has been done.
PostRefine_LowChords.wav - Previous refinements used all strings and a variety of chords. This one just used basic powerchords on the lowest three strings.
Set D:

ReferenceAmp_PalmLoops.wav - A looped snippet of the reference amp.
PreRefine_PalmLoops.wav - A looped snippet of the profile before any refining has been done.
PostRefine_PalmLoops.wav - A looped snippet of the profile after refining.
In all four cases as you can hear, the nature of the low-end response (particularly when playing palm mutes) is not that accurate to the real amp. I am wondering whether I am doing something wrong, or if the Profiler just isn't supposed to be this accurate? I am struggling to believe that though, because the likes of LasseLammert seem to have gotten much closer than I can.
Is it to do with gain-staging perhaps? I don't see how, but it could. I have an SM57beta in front of the speaker and about two inches away from the grille cloth. It's then plugged straight into the Kemper. Nothing special going on here. I have an acoustically treated room, so room reflections shouldn't really be causing this.
To me it sounds like all of the pre-refine clips are much closer in the low end, but the gain amount and the high-end frequency response is quite different. So some amount of refining is needed, but maybe I am doing it wrong??
Any tips on how I can get closer folks??
