Sm58 microphone classic

The Shure SM58 microphone, released in 1966, is one of the most iconic and widely used models for live performances and professional recordings worldwide.

About this subject

The Shure SM58 is a dynamic cardioid microphone designed for vocal use, renowned for its durability and frequency response optimized for speech and singing. Since its launch, it has become a staple on stages of all sizes, from small clubs to massive stadiums. Its rugged construction, with a steel mesh grille and internal shock mount, allows it to withstand drops and heavy handling without performance loss.

Technically, the SM58 has a frequency response of 50 Hz to 15 kHz, with a slight presence boost in the mid-high range to enhance vocal clarity. Its dynamic capsule requires no phantom power, simplifying use with both analog and digital sound systems. Over 60 years after its release, it remains the best-selling microphone in the world, with over 100 million units produced.

Culturally, the SM58 has been present in historic speeches, from the US civil rights movement to legendary rock concerts. Artists like Freddie Mercury, Bono, and Mick Jagger have used the SM58 in memorable performances. Its association with human voice transmission is so strong that it has become a visual symbol of professional audio.

Interestingly, the SM58 was initially designed as a studio microphone, but its rejection of stage noise and feedback transformed it into a live sound reference. Unlike condenser microphones, it handles high sound pressure levels without distortion, making it ideal for powerful vocals. To this day, it is often compared to the SM57, its 'sibling' instrument microphone, which has a slightly different frequency response.

Frequently Asked Questions

Why is the SM58 so popular?

Its popularity stems from the combination of durability, consistent sound quality, and rejection of stage noise. It is reliable in adverse conditions and has a natural vocal sound with presence, making it a standard choice for live sound engineers.

What is the difference between SM58 and SM57?

The SM58 has a built-in pop filter and a frequency response with a slight mid boost for vocals. The SM57 has a flatter response and is often used for instruments like guitar amplifiers and drums. Both share the same capsule, but the grille and shock mount differ.

How to maintain an SM58?

Clean the grille regularly with mild soap and water (remove the capsule). Avoid extreme moisture. Store in a case. If volume drops or crackling occurs, the capsule may need replacement, but they typically last decades with careful use.
