Key Features

  • 0 Hz to 20 kHz frequency response
  • Selectable low-frequency response: flat, 6 or 18 dB/octave rolloff
  • Low noise and high output clipping level
  • Cardioid polar pattern, uniform with frequency and symmetric about axis, providing maximum rejection and minimum coloration of off-axis sounds
  • Phantom powering (DIN 45 596 voltages of 12 to 48 Vdc)

The Shure SM81 is a high impressive very affordable microphone. This cardioid condenser microphone continues to please users and experts everywhere with its transparent and clear sound that’s comparable to premium tube microphones. Because of its small diaphragm design, this mic is lighter (1.63 lbs) and easy to position than most, handles loud sound sources better with a max SPL (sound pressure level) of 136dB (146dB w/ the built-in Pad), and as such it captures the nuances of acoustic guitars much better – be it during loud strumming or when carefully fingerpicking.

The usual downside of small diaphragm mics is its lack of frequency response, but this doesn’t seem to be very noticeable with the SM81, with its frequency response of 20Hz-20kHz. Reviews are consistent in saying that this mic gives you more sound quality per dollar than similarly priced microphones. And since this mic is crafted by Shure, you can be assured of reliability and consistency without having to shell out too much dough. It’s really hard to find fault in this mic especially for acoustic guitars, other than its natural limitation of not having the same low frequency emphasis as large diaphragm mics. If you are looking for a reliable acoustic guitar mic that doesn’t color your sound, the Shure SM81 is a great choice.  It is certainly one of the best microphones for recording acoustic guitar.
