A versatile, flat-response mic for acoustic and high volume performance applications.

The SM137 is a versatile, flat-response cardioid condenser probe microphone with an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high-volume performance applications.

  • Ultra-thin diaphragm for smooth high end and tight, controlled low end
  • 15dB pad for performance consistency across a wider range of high SPL sources
  • Low self-noise and transformerless preamplifier circuitry

    Comments about Shure SM137 Condenser Instrument Microphone:

    My duet partner and I both use SM137's to mic our acoustic instruments (6 & 12 string guitars, mandolin) in practice and performance settings. Thankfully, we have a Phantom Power setting on our mixer which allows simple easy use of the condenser mic's without batteries and no interference with our dynamic vocal mic's. The SM137's provide a true "unplugged" sound of our Martin and Taylor's, which is soooo much better than pickup equipped acoustics. Yes, there are better and more expensive acoustic condenser mic's out there, but for the money these are hard to beat.

    Shure SM137

    Comments about Shure SM137 Condenser Instrument Microphone:

    For its size and configuration it provides a wide range of uses and applications. From instruments to vocals it is very versatile and dependable.
    I like the microphone, but no "off" switch.
    Very solidly built and compact.

    Great condenser mic!

    By Wunderwhirl

    Comments about Shure SM137 Condenser Instrument Microphone:

    Bought this mic for my little home studio. Have been using it for a few months now and I am very please with it. Works great for just about any application! I use it for acoustic guitar, drums, vocals and clean guitar. Have tried it on distorted gutiar but it just doesn't capture the crunch, but if you pair it with a good dynamic you get the best of both worlds! Built like a rock (but thats Shure for you. I would highly recommend this mic if you're looking for a good pencil condenser that is fairly versitle.
