The Dark Side of the Shure SM58: Uncovering the Disadvantages of a Legendary Mic

The Shure SM58 is a legendary dynamic microphone that has been a staple in the music industry for decades. Its durability, versatility, and affordability have made it a favorite among musicians, sound engineers, and public speakers alike. However, like any other product, the SM58 is not perfect, and it has its fair share of disadvantages. In this article, we’ll delve into the not-so-glamorous side of the SM58 and explore its limitations.

Frequency Response Limitations

One of the most significant disadvantages of the SM58 is its limited frequency response. The mic is designed to capture the human voice, which iswhy it performs exceptionally well in the mid-range frequencies between 100 Hz and 8 kHz. However, it struggles to capture high-frequency details above 10 kHz, which can result in a dull and muddy sound.

This limitation is particularly noticeable when recording acoustic instruments or capturing ambient sounds. The SM58’s frequency response is tailored to emphasize the lower midrange frequencies, which can lead to a boxy and lifeless sound when recording instruments that require a brighter, more detailed sound.

Lack of Clarity in the High-End

The SM58’s high-end response is also limited, which can result in a lack of clarity and definition in the sound. This can be particularly problematic when recording vocals, as the microphone may struggle to capture the subtle nuances and articulations of the singer’s voice.

In particular, the SM58’s high-end roll-off can make it difficult to capture the crisp, sharp transients of percussion instruments, leading to a dull and lifeless sound.

Proximity Effect

Another disadvantage of the SM58 is its proximity effect, which can cause the microphone to pick up excessive low-end frequencies when placed close to the sound source. This can result in a booming, bass-heavy sound that’s difficult to correct in post-production.

The proximity effect is particularly problematic when recording loud sources, such as drums or bass amps, as it can lead to an unbalanced sound.

Correcting the Proximity Effect

To correct the proximity effect, engineers often use a technique called “dialing out the low end.” This involves reducing the low-frequency response of the microphone to compensate for the excessive bass pickup. However, this can also affect the overall tone and balance of the sound, leading to a less-than-ideal outcome.

Limited Sensitivity

The SM58 has a relatively low sensitivity compared to other microphones, which can make it difficult to capture quiet or distant sources. This limited sensitivity can result in a weak signal, which may require additional gain staging or booster amplification to achieve a usable level.

This limitation can be particularly problematic in live sound applications, where the microphone may struggle to capture the sound of a distant performer or instrument.

Polar Pattern Limitations

The SM58 has a unidirectional polar pattern, which is designed to capture sound from the front while rejecting sound from the sides and rear. While this can be useful in reducing ambient noise and feedback, it also limits the microphone’s ability to capture a wide, immersive sound.

This limitation can be particularly noticeable in live sound applications, where the microphone may struggle to capture the sound of a large ensemble or orchestra.

Using the SM58 for Ambient Recording

If you want to capture a more ambient sound with the SM58, you can try using it in a omnidirectional or bidirectional pattern. However, this will require additional processing and editing to correct for the microphone’s inherent tone and characteristics.

Durability Concerns

The SM58 is renowned for its durability and ability to withstand rough handling. However, like any other microphone, it’s not indestructible. The microphone’s grill and windscreen can be damaged if not handled carefully, which can affect its performance and tone.

In particular, the SM58’s internal components can be susceptible to moisture and humidity, which can cause corrosion and damage over time.

Proper Care and Maintenance

To extend the life of your SM58, it’s essential to handle it with care and follow proper storage and maintenance procedures. This includes storing the microphone in a dry, cool place, avoiding extreme temperatures, and cleaning it regularly with a soft-bristled brush and gentle soap solution.

Alternatives to the SM58

If you’re looking for an alternative to the SM58, there are several options available on the market. Here are a few popular alternatives:

  • Shure Beta 58A: The Beta 58A is a high-end version of the SM58, offering improved frequency response and a more detailed sound.
  • Sennheiser e835: The e835 is a popular alternative to the SM58, offering a brighter, more detailed sound and improved high-end response.

In conclusion, while the Shure SM58 is an exceptional microphone in many ways, it’s not without its limitations. By understanding its disadvantages, you can make informed decisions about when to use it and when to explore alternative options. Whether you’re a musician, sound engineer, or public speaker, it’s essential to choose the right microphone for the job, and the SM58 may not always be the best choice.

By acknowledging its limitations and using the SM58 in the right context, you can unlock its full potential and achieve exceptional results.
