If you're looking for a warm, natural sound, you should try to find a ribbon microphone; and if you're also looking for a true figure-eight polar pattern, then let your search end with the Beyerdynamic M 130.
The M 130's unique double ribbon element has a superb transient response, supplying a highly detailed, accurate and transparent sound, while its bi-directional figure-eight polar pattern suppresses unwanted interference from the sides. Its rugged design handles the demands of remote recording/broadcast sessions as easily as those of the studio. On its own, the M 130 allows the recording of background audience noise and concert hall ambience without unwanted resonance. In the recording studio it is effective with backing vocal groups, percussion and mounted toms, and is especially effective with strings. The M 130's crisply articulated, uncolored sound is also perfect for digital and direct-to-disc recording.
