I was recently part of a session recording Brittany Studer's film score of "The Silence" and was recorded using a Shure SM58 more or less directly at or below the bridge.
The mic sounds pretty good, but is obviously not directional enough to create really good isolation between instruments, as you'll hear below. It also doesn't really bring out the best frequencies of the bass, particularly bowing it, though I think that is because of the bridge placement with nothing else to blend in.
These audio clips were recorded direct from the Shure SM58 into a Tascam DR-680 in a large venue with concrete floors and high ceilings.
Here are some crazy sounds I made at the end of the session. Any composers out there who are curious how I made them, feel free to ask below!
