Firstly pick either amp,

Gaff tape the Beta52 to wherever on the amp you get the most bass response. In front of a speaker is fine but we want physical transmission, yeah baby.

Put the 57 in front and into a tube pre. Mid-cone, a little off axis. Hit the tube hard.
Put the 58 in the back of the amp through a clean pre, out of phase. Try to get like the same spot and distance from the cone as the 57 but in reverse... or don't (not that important but fun to experiment)

The 4040 goes like, I don't know, 6 feet away or so. Move it around for some womp womp. WTF, put the studio channel on that. Avoid using the compressor on it.

Now the fun part: Hang an omni from a wire in the middle of the room with a 1 pound weight on it... or a pair of cardiods back to back... You'll need windscreens for this part...

Swing the pendulum, hit record.

Pan everything to ear except the 52, of course, stays center. Delay the 57 and 58 like 18 samples for some fake time alignment to the 52, WTF. Take to 4040 and do the "make stereo" spread thing to it: split eq/hard pan/short delay/micro chorus/etc thing. Whatever wide you like. I like microchoruses and split mid-high EQs, personally. Subgroup those channels and then M/S EQ the sides with a little sizzle. Compress the whole sub-group but not too hard, just a tiny but of suck but mostly transparent. Add the 52 in just for uncompressed chunk. When you want a sick "how did you get that sound?" phaser use the pendulum, lol.

Result?
Awesome... or not... Try the other amp/guitar.

Might sound terrible. Either way, at least you get to hear how this sounds.

But what does huge sound mean anyway? Like giant reverbs or fat tight amps or psycho-acoustic LSD delays? You can get huge huge sounds simply by using one 57 and 3 different amps with 3 different guitars that are O so slightly out of tune to each other. Just track it 5 times and pan hard... o yeah and avoid the low-mid mud.
