Produced from 1949 to 1974, the M 49 is best known for its use on Miles Davis' trumpet and vocalists Simon and Garfunkel, and Barbara Streisand. The M 49 was the first condenser microphone capable of remote pattern control, and of course our P-49 has a remote indexed 9-pattern selector. The unique slanted relationship of the head grille to the capsule reduces grille resonances. The miniature triode tube's design is particularly well suited for microphone use, with long life, low current consumption, and high input impedance. Despite the high cost and complexity of developing the right output transformer, this is the final crucial step in achieving the vintage '49 tonal quality. The P-49 makes a superb vocal mic. With mid-range detail and unique high-end smoothness the P-49 brings saturated warmth to vocals, violin, or drums.
