Independent shopping perspective
The CM-300 is a black clip-on contact microphone for sending an instrument's vibration directly to a tuner. Its piezo element works from the instrument itself, helping maintain high-precision tuning in loud surroundings such as a large ensemble. KORG also revised the cable strain relief at the unit connection for greater durability than the previous model and improved sound transmission performance. It is a straightforward tuning accessory for environments where ambient sound can get in the way.
