Studio Mic Can Handle Live Gigs, Too!

The Shure KSM137 is an end-address condenser microphone with a cardioid polar pattern. Designed for studio use, yet rugged enough for live applications, the KSM137 can withstand extremely high sound pressure levels (SPL). Its low self-noise and extended frequency response make it ideal for recording musical instruments.

Shure KSM137 Features:
  • A highly consistent cardioid polar pattern
  • Ultra-thin, 2.5 micron, 24 karat gold-layered, low mass Mylar diaphragm for superior transient response
  • Class A, discrete, transformerless preamplifier for transparency, extremely fast transient response, no crossover distortion, and minimal harmonic and intermodulation distortion
  • Premium electronic components, including gold-plated internal and external connectors
  • Subsonic filter eliminates low frequency rumble (less than 17Hz) caused by mechanical vibration
  • Switchable 15dB pad for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable pad (0dB, 15dB, and 25dB) for handling extremely high sound pressure levels (SPLs)
  • Three-position switchable low-frequency filter reduces background noise and counteracts proximity effect
  • Extended frequency response
  • Low self noise
  • Exceptional reproduction of low-frequency sounds
  • Can withstand high sound pressure levels (SPL)
  • High output level
  • No crossover distortion
  • Uniform polar response
  • Superior common mode rejection and suppression of radio frequency interference
  • Requires +48V phantom power

A great all around mic for live sound

Bought this after my beloved AKG 451 was stolen. Needed something for hi hat primarily but also for acoustic guitar and piano and this does the trick beautifully. The DB filters are especially helpful, allowing me to drive the pre amps on my Midas a little harder for the best of both worlds. Love getting phone calls from Luke Herian, every time I see that number pop up I always answer "Hi Sweetwater, I mean Luke...". Great service, Sweetwater folks have this down to a science. Cheers!

I purchased this mike through Sweetwater a few months back and have really put it to much use. My background is acoustic music and like the other reviewers I have found this mike to work well with guitar, violin, mandolin, banjo, and even acoustic bass. I do a lot of overdubs on my own projects and it's nice to have a mike you can leave set up that works so well for so many different types of instruments. I usually record into a macpro, with Logic 8 through the Duet with no other outboard gear. I do not have experience with the high-end(priced) mikes but I think Shure is one of the best values around. (I also respect the SM7!)

Awesome mic

This is a very natural and open sounding mic. It has a slight presence bump around 4-7khz. The low end seems fairly flat maybe tapering off a bit. I bought this mic mainly for close miking hats. Turns out, it's great on acoustic instruments. Banjos and mandolins sound great. Acoustics sound good but I think the Neumann 184 still Wins. but, considering the price difference it's great. And pretty close sounding.

By far the best in class!

I have used well over a dozen different SDCs in the sub $1000/pair range and the only ones I've found worth having thus far are the KSM137s (and 141s). I kept putting off buying a pair of these, thinking they would perform similarly to the rest. I am so pleased to say I was wrong! While other mics in this price bracket have smeared transients and annoying resonances, the KSM137 is crystal clear, fast and resonant free! Smooth low end and mids, with a just right presence that is NEVER harsh, glaring, distorted or brittle, yet airy and so pleasing. Cymbals sound stellar, as do various acoustic string instruments. If you can only buy 1 pair of SDCs on a modest budget, these are it! You wont out grow them either, as even if you have popular high end SDCs in your cab, these will still find lots of use! Given that the stereo kit of these is well under $700, I find this to be the best value in SDC mics around and one of the best values in pro audio period, only to be bettered by the sub-$800 priced dual pattern KSM141s.

KSM 137

LIke another reviewer, I have been able to put this mic up against several others when recording acoustic instruments. I have found none better, even those costing hundreds of dollars more. This gives a very "uncolored" flat respsone, yet warm through both of my DAW's (Protools and Cubase). It works equally well on banjo, acoustic guitar, and mandolin. Our banjo player uses this mic in live settngs and I love it when I'm on the board. I'm now in the market for a couple more.
