Well, I have several of the mics that at least some of the folks used.
That's the Sennheiser MKH-110. It has a frequency response down to 1hz!
It's a Omni designed for test instruments. I'm fitting a couple of them
to a SASS enclosure. Finally got brave and milled the holes through the
enclosure recently. Still have to put in the supports that will hold the
O-rings to help to keep them isolated. Then build a power supply into
the SASS for them. They take 8 volts!

I'm not sure what was used for a recorder. I only found out that the
MKH-110 was the mic used by at least some when I searched the internet
for info on the mic.

BTW, got the mics off Ebay, and the place still has more they are
auctioning. Just in case any of you want to chase elephants.
