In Cab block I'll cut somewhere between 80hz to 125z on lows, starting at 100...and then cut highs between 6kz to 10hz depending on amp...standard guitar speakers don't put out much frequency-wise over 6kz generally.
With that EQ approach, I look at this like a producer/arranging at a mixing board trying to make a guitar sit right with the other band instruments or how it would go on an album. It usually translates well to live.
Also now am going mono for live, any Cab IR pans at zero.
If am using a factory mic on an IR I will put proximity at about 2 and adjust to taste, but it usually is between 2 and 3.
Used to use the cab mics a lot, because you can get some very cool effects playing with that/room sounds, but the FAS reverbs are so good with ambience and small room option now that I don't touch the cab options for ambience much any more.
Have used the economy pre-amp just a little with drive at 1 and saturation at 1 or 2 on vintage, but honestly if I take it off it's hardly noticeable, so usually leave it off.
To save CPU processing I'll use stereo cabs blended (both pans at zero) rather than ultra res stereo setting.
Have fooled with the phase parameter but am finding if I get the right IR I don't need to touch it at all, the latest quantum firmware seems to work well with all the factory IRs.
