REPRICED/PC Shure sm57 Dynamic Microphones [ORIGINAL]

The Shure SM57 is a common professional low impedance cardioid dynamic microphone in live sound reinforcement and studio recording applications. It is a popular choice among live users due to its sturdy construction. It is often used on instruments that produce high sound pressure levels, such as the snare drum and other percussion, electric guitar amplifier, and even vocals. Introduced in 1965, the SM57 remains one of the best selling microphones in the world today.

The microphone uses an XLR connector. According to Shure, the frequency response extends from 40 Hz to 15kHz.

The SM57 is the microphone used on the lectern of the President of the United States. The capsule inside the SM57 is identical to the one in the SM58.
It is the windscreen that is different, which changes the sound. An SM57 cannot be turned into an SM58 or vice versa since the design of the top half of the outer casing is different.

There is a popular modification for this microphone which involves removing the output step-up transformer. This increases the bass response and creates a "smoother" sound. However the output of the microphone will decrease by approximately 10dB.
