But, you know, I moved away from the 4x12 route some years ago because so many bands were trying to get better FOH sound, so we started flipping our cabs around backwards on stage and mic'ing them, so I migrated down to a 2x12, then as I got older and the style of music started changing, i went Low Wattage, then down to a 1x12 ... so, for me, using the Axe Fx II with a CLR wedge ... my sound actually IMPROVED .. hahahaha ....
Even when I do gigs that require an FRFR onstage for bandmates (I run it across the stage versus towards the crowd) the IEMs are a a must.
I do exactly this ... i sit my monitor up on the front corner of the stage and wash it at a 45 degree angle so everyone can enjoy my love .. and i crank it up and i have had exactly NONE of the band members complain .. actually the other guitar player was asking how i could set something up like that for him so we can better hear him (he is using a standard 4x12 sitting in the standard location, doing the standard thing, and I or the bass player cannot hear ANYTHING of him on our side of the stage ones everything kicks in, and i have NO clue WHAT the sound guy is doing to him in the monitors lololol ... but he does not cut thru at all.
Here is my setup on a small stage format with VERY limited room ... worked like a champion
