Is simply to use both.
There seem to be an endless amount of treads regarding what fr/fr solution is the best or if a cab onstage is better.
To me the solution is easy. Dial in a bit of your profile (I use kemper) in the bands wedges for accuracy and to get an idea of how it sounds Foh. And than you use a as neutral cab as possible and blend that with the sound from the wedge. Done. You get both the feel from the cab and the accuracy from a fr/fr system.
May not sound like a big of a deal. But people always seem to write about it like it has to be one or the other.
Anyone else goes about it this way?
