Hi there!
I've been using Kemper (non-powered rack-version) for about one year now, and there's one problem that still makes me crazy.
The issue is:
For example: When I play some classic hard rock riffs with medium gain (MBbritt JCM800 or ANY OTHER profile) with only one string, like solos or some GNR welcome to the jungle style riffing and then change to two- or more-string chord-playing, I get about 3db volume loss in my playing (I recorded and measured it with Pro Tools). Volume is fine with one string riffing and solos, but when I strum chords I get the volume loss. It sounds like a compressor or limiter, which reduces the volume when strumming chords.
This happens when I use the same profile and use the same picking dynamics on both playing styles. Is this normal behaviour of the Kemper?
With clean-only sounds, there's not this issue. I know that amp's overdrive compresses the signal a bit, but isn't -3db too much?
I've checked Kemper's input and output volumes and clean sens. There's no clipping, everything is fine. All volumes and compressors are "0" at the amp and cab sections. No effects, just the amp. I've tried both my Les Paul and Strat and different cables for guitars and outputs.
There's the same issue with studio and live (Kemper main or monitor out to stage-monitor) setup.
I would appreciate any help from you!
