When asked about why no bass profiles included Christop Kemper answered in the Kemper Forums:
True, we are focussing on guitar, and it's good to focus for a reasonable time.
But we always had bass players in mind.
I am happy to see bass players taking over.
The instrument input is capable of taking an active bass. Please take care to adjust Clean Sense in the input section to your level.
We have even generalized a bass paradigm: Most of our Chorus effects feature a Crossover parameter that remains the important bass fundamental unprocessed and stable. This is known from a famous bass chorus, but we found it also helps other instruments.
A famous german band (Die Toten Hosen, german charts leader) used the Profiler for their new album and play three Profilers on stage (Rock Am Ring). Two guitars and one bass.
