The powered KPA through a guitar cab with "monitor cab off" sounds fine, but I'm wondering if anyone uses it without engaging the "monitor cab off"?
Not that a guitar cab would be FRFR, but some might get close, for example a fairly neutral sounding cab with a smooth speaker with a good range like an EVM-12L. I've read that some modeler users prefer to disable the tweeters on their FRFR cabs and this would be somewhat similar. Maybe the monitor out EQ could add in just enough extra high-end if necessary.
Basically for smaller gigs, no FOH, no running through the PA, and in order to get the various profiles sounding a bit more realistic than "monitor cab off" might provide.
Thanks!
