Korg CM-200-BKRD Improved Design Contact Microphone for Korg Tuners - Red/Black
The CM-200 is a contact microphone that can be attached to the bell of a brass instrument, the bridge of a violin, or even to a guitar or ukulele. The microphone uses a piezo element to directly capture the vibrations and send them to the tuner. The CM-200 is an indispensable item in situations where the Mic built into a tuner might have difficulty detecting the sound of your instrument, such as during a practice session with an entire brass band.
