When it comes to live performances, having a reliable and high-quality microphone is crucial. The Shure SM58 and Shure Beta 58A are two of the most popular microphones on the market, and for good reason.

In this article, we’ll be comparing and contrasting these two microphones to help you decide which one is the best fit for your needs.

Build and Design

The Shure SM58 has a classic design that’s been around for decades. It’s a rugged, reliable mic that can withstand the rigours of touring and live performances. With its steel mesh grille and rugged construction, the SM58 is durable enough to withstand accidental drops and bumps.

On the other hand, the Shure Beta 58A has a slightly sleeker design than the SM58. It also features a hardened grille that resists wear and tear. The Beta 58A is slightly heavier than the SM58, but its overall build quality is equally impressive.

Sound Quality & Polar Patterns

When it comes to sound quality, both the Shure SM58 and the Shure Beta 58A are excellent choices. However, they do have slightly different sound characteristics.

The SM58 is known for its warm and full-bodied sound, which makes it perfect for live vocals. With a frequency response of 50 Hz to 15 kHz it can pick up a wide range of vocal frequencies making it ideal for most pop and rock vocalists. The SM58 also has a cardioid polar pattern that reduces background noise and feedback, making it perfect for live use.

The Shure Beta 58A, on the other hand, has a slightly brighter and more detailed sound than the SM58. With a slightly wider frequency response of 50 Hz to 16 kHz, which means it can pick up even more high-end frequencies than the SM58. The Beta 58A also has a supercardioid polar pattern, which provides even greater isolation and feedback rejection.

In terms of sound quality, both microphones are up there with some of the best live mics available so trying out both to see which suits your voice best is always recommended. The SM58 is a classic microphone that’s been used by countless musicians since it was originally released in 1966, while the Beta 58A offers a slightly more detailed sound.
