KORG CM-400 WH Clip-on Contact Microphone for Tuners, White

This clip-on contact microphone attaches to your instrument and transmits vibrations directly to the tuner. It allows for more accurate detection of your own sound, even in environments where you're more susceptible to surrounding noise, such as when practicing with a large group of people. The cable is made of a flexible material. The slits at the clip joint reduce strain on the wire, making it less likely to break. It features a mini plug that's perfectly compatible with the TM-70 tuner/metronome. The clip opens to a width of 30mm, allowing for secure attachment to a variety of instruments, including the bell of a wind instrument, the bridge of a violin, and the head of a guitar or ukulele.
