Product Introduction

The Shure SM137 is a professional cardioid condenser instrument microphone designed to deliver natural sound reproduction in both studio recording and live performance environments. Featuring an ultra-thin diaphragm, a transformerless Class-A preamplifier, and a built-in 15dB pad, the SM137 ensures smooth highs, tight low-end response, and consistent performance even with high SPL sound sources.

It is ideal for miking acoustic guitar, cymbals, strings, piano, and other instruments, offering low self-noise and excellent clarity for professional musicians and engineers.
