Thanks Jörn for your reply.

Unfortunately the organ at this church only has a 16' pedal :( In any
case I don't want to be throwing any of those lovely deep frequencies away.

I've never used omnis in any situation before, but I'll see if I can
rent some to see if they give good results before buying. I don't have a
lot of money to spend on volunteering at the church, but I would like to
produce the best results possible with the available funds.

Thanks for this tip also. AB is a bit more tricky, because one
microphone would have to be either side of the aisle, and the
powers-that-be are not keen on having cables strung around with a full
church. I'll see what I can do...

If anyone is interested, I've written this up in a post on my blog, with
a diagram of mic placement and some sample recordings using condensers
and dynamics. Any feedback (whether as blog comments, or replies on this
list) would be very welcome.
