Display MoreIt seems to me that I am experiencing similar problems when creating a direct amp profile of an EVH 5150III (which has obviously been DI profiled successfully a thousand times). I must say, that I'm quiet confident I took care of everything as suggested as I read almost all the info I could find on this forum and the web:
- Connections: Just as shown in the manual, guitar->Kemper->Kemper direct out->Amp Input->Amp Output->DI-Box (PAD -40dB)->XLR-out->Kemper return Input, + DI-Box->Cabinet
- All cables are okay, DI-Box (passive) new and without any Cabsims
- All FX (stomps and post stack) switched off
- clean sense low enough so that the input LED remains green all the time
- return level low enough so that the Output LED remains green, too (tried many different levels, though)
- DI-Box is the admittetly cheap Millenium DI-E from thomann, but it was sold 998 times, 4.4 out of 5 stars... well...Every time the result is a sound with too much rumbling in the bass which simply doesn't exist in the reference amp. Strangely, when comparing the dry Kemper-DI-profile (without cab) to the reference-amp-output-signal (again without cab) there was a significant difference: The bass rumbling only occured on the Kemper-DI-profile. The reference amp, eventhough monitored through (!) the cheap DI-Box, sounded as it should. (That's why I hopefully can eliminate the DI-Box as a source of the problems.) Well, we swapped the amp for another EVH and the results were better, but the rumbling remained at least audible. BUT here comes the even worse part:
The kemper's presence knob as well as the treble show some really strange behaviour when tweaking the DI-profile:
- dialing the presence up results in metallic/shrill and unharmonic overlapping sounds while even becoming kind of out of tune...? I cannot find such a behaviour in any other profiles I own nor on the reference amp itself.
- the same is true for treble, worst results occur when dialing up presence above 2 o'clock and treble at the same time. It just does not sound like something you would expect these knobs to do... well, not even a heavy metal guitar amplifier
(- less severe, but the same goes for the gain: the knob's behaviour is not reproduced accurately, the highest levels of gain seem digital and unpleasent)Now, my questions:
What am I doing wrong? Is it possible that the KPA gets into trouble, when trying to reproduce higher values of any knob setting on the reference amp?
When profiling an amp, what settings should be used on the reference amp? Is it okay to dial in presence (or anything else) at 3 o'clock or should I use "flat" Settings at, let's say 12 o'clock? Or should "the perfect sound" be profiled "as is" in any case? Apart from clipping: Does the return level have any influence on the resulting profile? (The manual says that it doesn't, because the KPA adjusts the level anyways... but as of now it remains the only questionable part I can see, apart from the cheap DI-Box of course.)Thanks a lot for any help!

There shouldn't be a problem with your choice of DI box, I think - see here: DI-boxes suitable to create Direct Amplifier Profiles
I'd contact support - this sounds a bit strange there's a link in my signature
