Sm58 microphone classic

The Shure SM58 is the most iconic dynamic microphone in the world, a staple on stages and in studios for over five decades.

About this subject

The Shure SM58 was launched in 1966 and quickly became the industry standard for live vocalists. Its rugged design, with a steel mesh grille and cardioid capsule, provides high durability and rejection of off‑axis sounds, capable of withstanding drops and harsh conditions without losing performance. The frequency response is tailored to enhance vocal clarity, with a gradual low‑frequency roll‑off to reduce proximity effect and a slight presence boost between 2 kHz and 10 kHz.

Although best known for live performances, the SM58 is also widely used in studios for recording vocals, voice‑overs, and instruments like guitar amps and drums. Its 150‑ohm impedance allows easy connection to mixers and interfaces, and its encapsulated cartridge minimizes handling noise. Shure estimates over 200 million units have been sold, making it the best‑selling microphone in history.

Culturally, the SM58 represents audio professionalism. It appears on tours by artists such as Bruce Springsteen and Madonna, on TV shows like American Idol, and in karaoke bars and churches worldwide. Wired (SM58) and wireless (SM58 beta wireless) versions continue to be updated, maintaining the legendary reliability that defines it.

Frequently Asked Questions

What is the difference between the SM58 and SM58 Beta?

The SM58 Beta has a wider frequency response capsule and a larger metal grille, offering higher gain before feedback and better noise rejection. The classic SM58 has a smoother sound and is more tolerant of wind and plosives.

Is the SM58 good for studio recording?

Yes, although designed for live use, many audio engineers use the SM58 in the studio to capture vocals with presence and to isolate sound sources in untreated environments.

How to properly clean an SM58?

Remove the metal grille and wash it with warm water and mild soap. Use a soft brush to gently clean the capsule. Avoid letting liquid enter the microphone's interior.
