Product Description

The Shure SM81 Instrument Condenser Microphone is perfect for acoustic guitarists and Instrumentalists. The SM81 lets you reproduce your instrument with the highest fidelity.
The razor flat 20 to 20K frequency response of this low impedance, unidirectional, cardioid condenser mic is faithful to every nuance of your expression. Built-in 10Db attenuator. Requires phantom power from board or external source.

The Shure SM81 is a high-quality, unidirectional condenser microphone designed for studio recording, broadcasting, and sound reinforcement. Its wide frequency response, low noise characteristics, and low RF susceptibility have made it a standard for applications involving acoustic instruments, especially guitar, piano, and cymbals.

The SM81 is ruggedly constructed. It operates on phantom power and performs over a wide range of temperatures and humidity conditions. It is furnished with a swivel adapter, attenuator-switch lock, foam windscreen, and case for carrying and storage. Other accessories are available.

Your general opinion of this product.


STYLE:
Orchestral

MUSIC EXPERIENCE:
lifelong

OVERALL:
I've had a pair of these for years and I've ended up using them for nearly everything. I record an enormous variety of instruments and sounds. These always sound great: live recording, drums, strings, speech, any accoustic sound. Properly EQed they will get exactly the sound you want. I've bought lots of other flavor of the month mikes, but I end up using these all the time. These have been around for ages, so they don't get much hype, but they're the real thing. I wouldn't use them for close-miking vocals or kick drums, nor would I take them on the road. I've banged them and dropped them a few times with no ill effects, but I wouldn't want to make a habit of it.

Your general opinion of this product.


QUALITY:
I give it a ten on quality, features & performance

FEATURES:
Db cut & high pass filter. New rubber clip is much better although the old spring clip was o.k.

SOUND:
Some pro studios use these as overheads, as I do. The semi-famous fusion/jazz drummer Dave Weckl uses them as his overheads for live & studio work and they sound great. Check out his bands album "Synergy" to hear how well they record.

STYLE:
Rock, bluesy stuff, Trippy stuff.....

MUSIC EXPERIENCE:
Drumming since 1978, recording since 1986.
