possibly the last mic that I would ever sell. I have a pair of 441's and a pair of 541's(basically the same without Music/Speech HPF switch)
One of the best sounding dynamics out there - killer on snare if you can fit it in there, but I used to use them a lot for live recording - on a guitar amp the isolation is ridiculous with the hypercardioid pattern.
I've used them on vocals (Fleetwood Mac/Zappa used to do the same) drums, guitars, bass cabs....really anything. Respond great to EQ as well....
