Could be cool if the main EQ block was just the studio or graphic eq with high and low cut options. That would save a effect block
It wouldn't be a lot like an amp without the traditional bass, mid, treble and presence, although I guess that could still be an option. What would maybe be better is a studio eq with more than 2 parametric bands instead of sometimes using two slots for eq.
An input eq could be nice too!
+1 for the output studio eq.
This wish is not really new.
The pass filters might be accessible\visible only via the menu, while the basic knobs could still be usable from the unit's front.
IMO, we need a band-pass system per rig (be it in the Stack, in the Cabinet, in the Rig menu), because the need/utility to bandpass a tone comes from the interaction between that specific amp and that specific cab.
If we assume that the Profiler generates a mic'ed cab's tone, the most logic (and useful) option is to allow bandpassing that specific tone, exactly the way the soundman does on the strip where the mic enters.
Having such a function in the Output section wouldn't solve the issue bandpassing is expected to solve.
I believe the best place would be the Cabinet section, since (mic'ed) cab is the element that would most likely require bandpassing. But the Rig section would be a sensible location as well, for the above-mentioned reasons.
