Beyer say :
Another microphone from the "workhorse stable", the M 201 TG preserves its place in history through sheer performance and reliability and we are proud that it has come to feature here with the classics. A truly sensitive dynamic microphone with a range of applications spanning instruments to vocals, being particularly effective when the microphone has to be placed at a distance from the sound source. It incorporates a "hum-buck" coil that rejects mains borne interference introduced when using the microphone close to video monitors or other mains powered devices.
We say that is a very good all rounder that no studio should be without, great on vocals as well as on guitar cabinets..
