you can use DPA miniature mics for ambiance (omni 4060 or 4061 enventually with dedicate DPA miniature preamp), they are relatively cheap for the quality.

2 things no-one mentioned afaik.
If you're signal is going through your looping rig
then *that* is going to impact on audio quality.
This *may* mean that using a studio won't make a lot of difference.
Using the natural reverb of a church for looping needs
some pretty good monitor speakers. (*good* being
your subjective preference).
...and at least 2 more microphones with pre-amps to
get the ambience.
