Cool. Yes, the main thing is to experiment a lot, because there are so many variables.
Like people often say don’t use fig-8 mics when you don’t want too much room, but true fig-8 ribbon mics have very deep side nulls, much more so than cardioid. So you can null really loud things from across the room. Same with low ceilings and early reflections. They can make mics you would normally use not sound so good and make mics you wouldn’t think would work well work better simply because they have a smoother or darker response. It really just depends on the room and placement what works or not.
Try miking the drum shell too.
I think it’s always good to throw random mics up for the controlled bleed sound heard on 60s records (like from a vocal or horn mic), which brings the excitement. Drummers tend to like that sound, for good reason.
I really like the RE-10. For live vocals, and can get a nice sound on silverface or Ampeg VT amps and sometimes rock snare, generally a 70s thing.
I often see the omni 635a recommended by those with experience for room mic, mono drum mic and amps, but I haven’t used it myself. I have heard room mic recordings and it can certainly sound good in that role.
The best 57 I’ve heard is the TAB transformer mod. Makes the response a bit fuller and less edgy. There are those who swear by the Unidyne 57s but I think the TAB has the most resolution.
Have you tried putting the Sphere down low, maybe 6 feet back from the kick? Sometimes you can get a nice depth/bloom that way. Useful for slower tempo songs.
A Beyer M88 can sound really impactful on kick, bass cab, and pretty detailed condenser-like on vocals. You have to get the pop shield though.
