The Shure SM58 is a legendary cardioid dynamic microphone, widely used for live vocals and recordings since 1966.

About this subject

The Shure SM58 is a dynamic cardioid microphone designed to reject off-axis noise and isolate the main sound source. Introduced in 1966, it quickly became an industry standard, gracing stages of all sizes from small clubs to major festivals. Its rugged build, with a steel grille and die-cast metal body, ensures resistance to drops and daily abuse, earning a reputation as 'indestructible'.

The frequency response of the SM58 is specially tailored for vocals, with a slight boost in the mid-high frequencies (around 5 kHz) to enhance clarity and presence. The capsule includes an internal pop filter that reduces plosives and wind, eliminating the need for extra accessories in many situations. Output impedance is low (150 ohms), allowing long cable runs without signal loss.

Culturally, the SM58 transcends technical gear as a symbol of practicality and reliability. Artists like Frank Sinatra, Bono, Bruce Springsteen, and countless karaoke singers have used it. It is also found in churches, schools, and corporate events, making it one of the best-selling microphones in history. Though designed for voice, many engineers use it on guitar cabinets and drums thanks to its ability to handle high sound pressure levels.

Compared to the SM57, its smaller sibling, the SM58 has a more pronounced pop filter and a rounded grille. Both share the same capsule, but the SM58 is optimized for handheld vocal use. Despite the rise of condenser and digital microphones, the SM58 remains relevant due to its durability, consistent sound, and affordable price, making it a safe choice for professionals and amateurs alike.
