Beta 58A vs SM58 Buying Guide
Vocal Clarity and Presence
Both the Beta 58A and SM58 are excellent microphones for vocals, but they differ in their sonic characteristics. The Beta 58A, with its supercardioid polar pattern and higher output, often delivers a more pronounced presence and clarity, especially in louder environments. It tends to capture more high-frequency detail, which can make vocals cut through a mix more effectively. The SM58, a classic cardioid dynamic microphone, provides a balanced and warm sound, making it a reliable choice for various vocal styles and a good all-rounder. The choice really depends on the vocal style and the desired sound profile.
Build Quality and Durability
Shure microphones are renowned for their rugged construction, and both the Beta 58A and SM58 exemplify this. The SM58 is legendary for its durability, able to withstand significant abuse on stage. Its robust build makes it a top choice for touring musicians. The Beta 58A is also built to last, featuring a sturdy design and a dent-resistant grille. While the Beta 58A might have slightly more delicate internal components compared to the SM58, both microphones are designed for the rigors of live performance and regular use. Overall, both offer excellent value in this regard.
Polar Pattern and Feedback Rejection
The polar pattern significantly impacts how a microphone captures sound and its resistance to feedback. The Beta 58A uses a supercardioid polar pattern, which is more directional than the SM58’s cardioid pattern. This tighter pattern helps to reject off-axis sound, reducing feedback and allowing for higher gain before feedback, especially on noisy stages. The SM58’s cardioid pattern is also effective at rejecting sound from the sides and rear, but it is less focused than the Beta 58A, making it slightly more susceptible to feedback in challenging environments. This is a very important consideration for live performances.
Price and Value
The SM58 is typically the more affordable option, making it a great value for budget-conscious musicians and audio professionals. Its lower price point has contributed to its widespread popularity. The Beta 58A, being a premium microphone, usually costs more due to its advanced features, such as the supercardioid polar pattern and improved high-frequency response. Both microphones offer excellent value for their respective price points. The best choice depends on your budget and the specific features you prioritize. Both are very good choices.
