Needing help profiling hi-gain amps!

  • Hello everyone,


    I've tried to find help about this for days (google, KPA manuals, this forum) and I just don't know what else to do but write a new thread.

    I've had my KPA for about two years now but I'm sort of new to profiling amps and I have this problem:


    I'm trying to profile hi-gain amps and every time I get this weird creaking (?) sound that occurs when damping the guitar. It doesn't appear on the reference amp, just on the new profile. I've tried different miss, cabs and all cables (and yeah I use a speaker cable for the cab). Every time the same. I get good clean profiles. So after the profiling is done and I cross reference (A/B) between the just-made profile and the reference amp: it only occurs on the new profile. Refining doesn't help. And I've tried different volumes by adjusting the amp's power amp and pre amp gains, lowered the overall gain and volume and stuff. I've tried with and without different pedals in front of the amp. I have not noticed any clipping in my monitoring system or DAW before, during or after the profiling. What have I missed? What am I doing wrong?


    I connect my mic straight to Kemper.


    Here's a clip I made about this. The situation here is right after the profiling is done and I can change between "Kemper amp" and "Reference amp". First you can hear the Reference amp and then the Kemper amp.

    Here is another sample with different amp. Same situation right after profiling. First you'll hear "Reference amp" then "Kemper amp":

    I really appreciate if someone could help me get towards better profiles. Thanks in advance!
