As some have requested it - I'll start a series of tips again.
Here is the first one.
Sometimes a profile has way to much bass.
Why?
It could be the amp setup (from the real amp used during the profile session) - the cab, mic, mic placement, room .... everything
Why release such a bad profile?
Maybe the profile creator liked it this way - or did some mistakes ...
Or (more likely) this profile was created for another type of guitar.
E.g. profiles created for a Strat type guitar may sound bad when a Les Paul is used.
Solution:
Reduce the bass on the KPA
Yes, but then I get a thin sound!
The trick is - try reducing the bass before the amp block - not after the amp block.
The KPA EQ knobs are set behind the 'distortion generator' (called amp block in the KPA) - it can be switched to be before the amp block as well - but it's easier to put an EQ block before the amp (e.g. in slot D).
Reduce the bass in this EQ block - and - in case the sound gets too thin - add some bass after the amp block - either with the KPA knobs (set to post) or with an additional EQ block after the amp.
