Shure SM58 Myths 2 - Denting Grille

Like scars on a heavyweight prize fighter, a bashed and bruised grille reveals the long, hard road that an SM58 microphone has traveled. Like a bodyguard, the grille’s job is to take a beating to protect the “VIP” - the more-delicate microphone transducer inside. In this video, Chad Wiggins explains why a 58 keeps working long after other microphones have gone down for the count.

Question is the “RK143G” sm58 shure replacement grill the same as the one that comes on the original microphone ?

[@10111175]

Does the grille denting change the frequency response of an sm58 or a Beta 58 ?

This guy looks just like David Bowie! Great video!

Just curious... If the SM58 grille is designed to dent to protect the cartridge, then why does the Beta58A have a "dent-resistant" grille?

[@shure]

The shock mount system used in the Beta 58A is a different design from what’s used in the SM58, and it does not require the grille to act as a shock absorber. Therefore, the Beta 58A can use a hardened steel windscreen without risking damage to the cartridge.

Cool! Thanks for the answer!

This is good news. I dropped and dented my SM58 immediately after taking it out of the box, like a dingus

[@grondsmaak4]

I cant get it from the sm58 that i drop a lot in 20 years works perfect but i cant get the grill loose it's stuck ? any suggestions thanks

Why doesn't the 57 grille screw off like the 58?

Here is a link to Shure FAQ # 2102 that refers to the SM57 "rotating" grille: www.shure.com/americas/support/find-an-answer/rotating-grill-on-the-sm57 Although this FAQ notes that the rotating grille is a normal behavior for this model, it does not really explain why this design was chosen. The design engineer of the Unidyne III element, Ernie Seeler, wanted to make the grille of minimal size in order to minimize the acoustic effects of the grille. Generally, larger grilles have a greater effect on the polar pattern and frequency response of a microphone. Using a threaded attaching method would have made the grille substantially larger and would also have necessitated making the grille out of metal. In fact, the subsequent model 548 was essentially a Unidyne III element with a threaded metal grille. The grille of the 548 was somewhere in between the SM57 and SM58 in size. Although the model 548 was in the Shure catalog from 1968 until 1980, it was not nearly as well received as either the SM57 or SM58 or even as well as the 548 or 565. The fact that the SM57 remains as popular as ever probably attests to the integrity of the original design.

no need to get a new grille when you could unscrew it and then undent it ;-;
