The MD 421’s has been a fixture in recording studios since its introduction in 1960. Has a fixed cardioid pattern and five-position bass control
Generally fatter and tubbier sounding than a SM57. Really good choice for toms and anything you need a good round sound with some snap.
The MD421 has a 5-position bass roll-off switch. The switch is not marked with specific frequencies or amounts (dB) of cut. The “flat” position is marked M for Music; the other extreme is marked “S” for Speech, and cuts the low end by approximately 6dB below 500 Hz.
