Less common are the microphones designed from the ground up to perform best in a one-niche application.
Sax players are a breed apart.
On stage they can strut their stuff almost as much as guitarists, with an instrument almost as phallic. They can do this because they clip little microphones on to their bells, freeing them from the constraints of standing still in front of a microphone stand. Trouble is the little microphones usually aren't up to studio use, yet the players resent having to stand rooted to the spot in front of something that might actually record their sound properly. There are two models, dynamic and condenser, distinguished largely by their colour and the presence of a powering box on the end of the condenser's lead. The mount is common to both and resembles a small tripod, with a soft plastic covering round the ends of the legs.
