Wheresthedug, Thanks for your response. It's appreciated.
And you're right that a more surgical EQ would be the best option, but we don't have that. So in lieu of that, I just want the current Low & High Cut not to be global to both Main & Monitor Outs. A surgical EQ is great for fixing specific frequency issues, but more often I find that there's a pretty big discrepancy between the Main Out tone through a PA speaker and the Monitor Out thru a supposedly FRFR speaker, even like the KemperKab.
And worse, I find that when I turn the MonitorCab OFF to go thru either a regular guitar cab or the KemperKab's imprints, there's big inconsistency between profiles in how the CabDriver "subtracts" the cab portion of a studio profile. So, for example, in these cases, I want to be able to roll off more high end in the MonitorOuts, than I want to in the Mains. And the Presence and Treble controls are way too broad for that.
