The SHURE's KSM137-SL STEREO is a pair of end-address condenser microphone that features a high output level, low self-noise, and excels at reproducing low-frequency sounds. This instrument microphone comes with a gold-layered Mylar diaphragm, a preamplifier for transparency, a subsonic filter to eliminate low-frequency rumble, and a pad for handling SPLs. Close-miking of acoustic and electric instruments, drum overheads, brass/woodwind, ensembles, and even bass instruments like the double bass and kick drum are all recommended uses.
