On big stages with in ears and for recording:
- KPA + remote direct to desk with no cabs
On small stages and clubs:
- no KPA, but my custom made GrooveTone "Brüller No. 2" (handmade 30 W 2-Channel tube-combo) + Deeflexx + pedalboard (GigRig with 8 different pedals).
I personally hate FRFR-cabs for guitars, I've tried various ones and I'm owning a Matrix Q12A, but I've never used it. If my ears get the direct signal of an amp (club, small stages), I need the response, overtones, and natural feedback of a "real" tube-amp and cab. If I'm playing on big stages with in ears, the KPA is perfect for me. Because I don't want to be killed by my neighbours by miking up my 100W-Plexi, the KPA is also perfect for recording guitars in my home-studio.
I know that many are using FRFR- or guitar-cabs, but for me the KPA is made for going direct to desk and I don't get the right feel and response with Kemper + cabs, if I'm not using in ears or (good) studio-monitors.
Just compare your Kemper + cab (FRFR or normal guitar-cab) with your favourite tube-amp and guitar-cab via A/B-switch and then you can decide what you will prefer.
