I'm looking to keep improving my drum recording and so want to start using 3
ambience mics as opposed to the 1 mono Neumann TLM 193 that I normally use.

I'm looking to see from experience here what are decent choices for a pair
of condenser mics that I could use for the left and right ambience. If
possible can you give me choices for high quality mics and then some choices
for lesser counterparts (Chinese or Eastern block made mics). If possible
I'd like to buy two mics that I could use in other applications to get the
worth out of them.

For example:
Would two U87s be an option? Should I be using Omni pattern mics or would
TLM 103s (similar capsules) be a cheaper alternative?
Are there any SE mics up to the task?

regards,

Martin
