Any or all of those EQ options might be necessary...depends on the room. And thats the thing, global EQ is for fine tuning everything for the room you're standing in, not creating your tones. If you try and build patches with the Global EQ on, you're gonna end up with a colossal mess that will require constant tinkering.
I was just having a similar discussion in another thread, I'll cut and paste:
"Bottom line is, you have to set up your patches at the volume at which you intend to use them, with the Global EQ OFF, otherwise there will be problems. Trying to EQ the Fletcher-Munson curve away doesn't work...it's putting a band-aid on a bullet wound. You're likely to have the opposite problem now...if you apply tons of EQ to account for large volume differences, when you try and use those same patches again at bedroom levels and the same global EQ settings, they're not gonna be anything close to what you now have at stage volume...you trimmed the highs. When you now lower the volume significantly, they're gonna disappear altogether, and it's gonna sound like your treble and presence are at zero.
Global EQ is really for fine-tuning for the room you're playing in, not patch creation, or for boosting/cutting large swaths of the audio spectrum. You need to start with a clean slate, everything flat...otherwise you'll find yourself overcorrecting for volume differences all the time."
I can't play at concrete-melting volumes at home either...I have 3 sets of patches. One for live, one for comfy living-room volume, and one for headphones. It's never gonna work any other way, at least not conveniently. You're better off spending the extra time at the outset, creating patches for different uses, rather than constantly re-EQing everything to account for volume. It's more work up front, but you only have to do it once.
The first couple of rehearsals/gigs with new gear are always dicey. In 25 years, I've yet to find a way around that...
