Korg CM-200-WHBK Clip-On Contact Microphone White/Black

The Korg CM-200-WHBK is a purpose-built piezo contact microphone engineered for one task: getting accurate pitch information to a tuner regardless of what's happening acoustically around you. By reading mechanical vibration directly from the instrument body rather than sound waves in the air, it sidesteps the fundamental limitation of standard clip-on tuner mics — susceptibility to stage noise, adjacent instruments, and room reverb. For orchestral players tuning on stage, guitarists at loud rehearsals, or brass players in pit orchestra settings, that difference is immediately audible in the consistency of the tuner's needle.

Construction is straightforward and reliable. The brass-reinforced connection between the cable and the mic body addresses the failure point that has plagued cheaper contact mics, and the redesigned rubber interior of the clip holds firm on headstocks and instrument bodies without leaving marks. The passive piezo element means zero maintenance and no mid-gig battery failures. The white/black colorway blends unobtrusively on both light and dark instrument finishes. At 1.5m, the cable reaches most floor and desktop tuners without excess slack cluttering a stage setup. It's a simple tool with no pretensions beyond its function — and within that function, it performs with professional reliability.
