On the other hand, Picklemic runs R44, and prefers mics on-stage > snake > R44 + SBD > R44, and gets great results too.
Picklemic prefers it because he understands a fundamental rule of mixing live music. The PA is for sound reinforcement. In all but large venue shows, it's job is to add what's missing from the stage volume. Amps and Drums are loudest on stage, and vocals, keys, kick drum often need reinforcement in the PA.
In other words,
PA + Onstage Volume = Audience mix
So when you're taping
SBD + Onstage = What the audience heard but clearer and less room interaction
SBD + Audience you are mixing SBD with SBD + Onstage Volume not as natural of a balance.
So, what I like to do is,
SBD + Onstage + Audience (Audience needs time alignment)
SBD + Onstage + Stage mics aimed at audience
This gives you live ambience with clarity, and the ability to adjust for loud crowds.
