Shure SM137 Cardioid Condenser Instrument Microphone

From acoustic instruments to high-volume performance applications, the SM137 from Shure is a versatile, flat-response cardioid condenser probe microphone made to make you sound good.

This mic features a thin diaphragm, transformerless preamplifier circuitry, a Class-A preamplifier, a pad for performance consistency, and low self-noise. It’s ideal for a wide range of uses, including capturing instrumental audio from winds, brass, and strings. It’s also a great choice for close-miking and orchestra, vocals, and even spoken word applications.

Boasting a 15dB pad, the SM137 expertly delivers natural sound reproduction with a versatile, flat response across a wide range of high SPL sources. Its ultra-thin diaphragm allows for a perfect combination of a smooth high-end and a tight, controlled low-end. Its low self-noise keeps the focus on your music, with minimal distractions.

Also included in the box with the Shure SM137 Instrument Cardioid Condenser Microphone is a swivel adapter for fast, easy setup and perfect positioning, as well as a zippered pouch for safe storage.
