The SM57 is the most famous of instrument mics. It’s clean 40Hz-15kHz response has made it the mic of choice for generations. It’s a proven performer on guitar/bass amps, brass, harmonicas, snares, toms, and congas, but it’s not uncommon to see vocalists reach for it, too. It features a cardioid pattern, dynamic element, and a presence peak at around 6.5kHz. Despite all the microphones available today, the SM57 remains universally accepted.
