Whilst I dont mind providing them, but at the end of the day, the Kemper transmits a recorded signal.
in otherwords, your playing "x" profile as if you have that amp in the live room with mics attached, with a guitar you have much large tonal freq available and can be very pleasant to play alone, or in a mix situation because there is more detail, and more going on.
With a bass amp its much harder, as anyone with mixing experience knows that to get a bass tones to sit in the mix is troublesome at best. as it has to work with that chesty kick and work alongside to keep the bottom end tight. - and at the time of profiling there is no easy way of doing this without the music your working on at the time. its pure guess and "generic" - whist bass is best played with others, I appreciate that some players like to sit and play alone and thats totally cool.
Im not saying it cant and wont work, look the KPA is a magic box imo it can do what you want it to do. but with bass, some things are best left for "on the day of mixing" than downloading profiles from others in hope.
Hope that all makes sence
