The CM-300 is a clip-type contact microphone that attaches directly to your instrument. It features a piezo pickup that transmits vibrations from your instrument directly to your tuner, enabling accurate tuning even in high-noise environments such as ensembles. The cable strain relief has been redesigned at the point where it connects to the unit, improving durability compared to the previous model, with enhanced noise transmission performance. The microphone's functionality has been upgraded. The cable now transmits sound more efficiently and offers greater flexibility. The connection between the microphone and cable is more robust, reducing the risk of damage. The new clip opens 7mm wider than the previous version, allowing for a more secure fit on a variety of instruments. The rubber padding on the clip has been redesigned to provide a better grip and improved stability. The design features a sleek, modern look.
