Sm58 microphone classic

The Shure SM58 is a classic cardioid dynamic microphone, regarded as the global standard for live vocals since its introduction in the 1960s.

About this subject

The Shure SM58 is a dynamic microphone with a cardioid polar pattern, designed to capture vocals clearly while rejecting off-axis noise. Introduced in 1966, it became the best-selling microphone in history, present on stages across all musical genres, from rock to country. Its rugged construction, with a steel grille and durable body, withstands drops and heavy tour use.

The SM58's capsule has a frequency response of 50 Hz to 15 kHz, with a gentle mid-high boost around 5 kHz that helps vocals cut through the mix. An internal pop filter reduces plosives and wind, while a pneumatic shock mount minimizes handling noise. Unlike the SM57, which has a flatter response and is used on instruments, the SM58 is optimized for vocals, delivering a warmer, more present sound.

Culturally, the SM58 is more than a microphone, it's an icon. Used by artists such as Bono Vox, Freddie Mercury, and Chico Buarque, its black silhouette with silver grille is instantly recognizable. In Brazil, it dominates churches, bars, home studios, and major festivals like Rock in Rio. Its simplicity and reliability have made it the go-to choice for sound engineers for decades.

Fun fact: the original SM58 had a switch, but the current version (SM58S) keeps it optional. The name SM stands for 'Studio Microphone', though it is more commonly used live. Over 100 million units are estimated to have been sold, and it continues to be manufactured in the USA and Mexico under strict quality control.
