Expert Audio Engineering Commentary

Tonal Profile

Cardioid dynamic with a presence lift around 4 kHz and a bass rolloff that keeps proximity effect in check. Frequency response is 50 Hz to 15 kHz, so there is nothing below the voice to fight with.

Gain Staging Advice

-54.5 dBV/Pa is 4.5 dB hotter than an SM7B. Close vocals land at roughly 45-50 dB of gain, which every interface on the market has. The SM58 is not one of the hungry dynamics, whatever the forum says.
