They are both important factors, but room can make a huge difference.  If you
set up baffles correctly you can get a pretty "dead" sound to work with.  I
find that if you have baffles to absorb the sound and a decent condenser mic (I
like the AKG 414), then you are all set.  That ensures a pretty dry sound
anywhere.  If your mic is dynamic you won't get as much detail, so you
definately want a condenser (generally faster response).  Add a few dB of
compression if needed and you'll get a recording with low SNR.  Now here is
where I'm willing to sacrafice quality for the sake of aesthetics.  I prefer
analog tape to digital formats for low frequencies, then transfer the tracks to
pro tools for editing...

Which leads me to a related question-does anyone know of any circuits to put an
analog tape deck or tape echo under voltage control?
