The SM57 was created by Shure. Shure can be traced to 1937, when Shure engineer Ben Bauer developed the first single-element directional microphone, the Unidyne, which had a cardioid pickup pattern. Then in 1959, another Shure engineer, Ernie Seeler, advanced the microphone design significantly with the Unidyne III. Seeler torture-tested the Unidyne III threw three years of research and development. The end product of his testing was the SM series of microphone capsules. The SM stands for “Studio Microphone”. Today the microphone is widely used during amplified concerts but it can also be used to mic an orchestra. The SM57 has also been used in many presidential debates, to hear how it sounds when someone talks into it click here. The SM57 is an industry standard for snare drums, toms, guitar amps and other components of rock groups which is why I gave it a 5 star rating, it worked perfectly wen I used it to record a band.


The SM57 has a sturdy construction and ability to work well with instruments that make high sound pressure levels like percussion instruments and electric guitars. I noticed it also worked well for me when I used it to reinforce the sound from the guitar amplifier. The SM57 also has a cardioid pick up pattern that reduces background sound and the generation of unwanted background noise. Its frequency response is 40 to 15000 Hz and it does need a fair amount of gain at the preamp, about 55-60 Db. The connecter for the SM57 is a three-pin male XLR. Below is the polar pattern of the SM57 along with its frequency response.

The only problem I encounter with this mic was that once or twice it created a high-frequency peak from the high-end that distorted a little. Another family member to the SM57 is the SM58 which is and XLR conneter microphone with a ball grill and pop filter.
