Question:How does the SM58 differ to the SM57?
The SM58 and the SM57 use the same mic element, the Unidyne III. The only difference between these two models is the grille design. The grille design does affect the high frequency response, particularly above 8,000 Hz. The SM57 grille design allows more proximity effect because the mic diaphragm can be placed closer to the sound source. Remove the ball grille from the SM58 and it will be more similar to the SM57 in its low frequency response.
