Problem with clean sounds - (distortion on 3 strings)

studioevolucija · May 13th 2013

Hello,

I own kemper profiler rack version since end of april. First let me say, that I am totally satisfied with it and that it works really good. Sounds are top notch. But I have one problem with clean presets. Almost every note on (low)B E and A string, sound distorted. I tried several guitars (active and passive), different magnet positions and result is always the same. Clean sense is set to 0, input led is always green ( and so is output led). Distortion on clean sounds is heard even if I play it gently. If I disable amp section of the stack, distortion goes away. Also when I set power sagging to maximum, this distortions is much lower in level and sometimes even disappears. Below is the link to the sound file. First part of the file is normal take, second part is with power sagging set to maximum. This problem occurs on all the clean rigs. Any solution for this problem?

What rig is this with? I mean the recording?

studioevolucija · May 13th 2013

This recording was made with my own rig/profile of mesa boogie mk4. This problem occurs on all clean rigs (factory or non-factory).

Never mind.

I'm asking because sometimes what is described as clean is not exactly entirely clean at all.
But of course, if you compared to your amp and shot the profile yourself, you should know how it's supposed to sound.

Wich firmware version do you use?
Have you tried the 1.8 beta?

I use 1.7. Haven't tried 1.8 beta yet.

I would try 1.8. what about the sound if you plug a headphone in the kpa?
Have you tried a system reset ( after backup)?

Since you are using a standard guitar that sends all six strings mixed on a single signal, there is no way the KPA can discriminate between strings. The only way a string can be louder than another is by adjustment of the pickups. Perhaps balancing the pickups will help.

I noticed the same with my LesPaul guitar - only that one has some problems with clean sounds distorting - and only if I play the strings strongly.

Levels are all fine (green) and without the amp block all is fine too.
