Korg CM-400 Tuning Clip Pick Up for TM70T

The CM-400 is a clip-type contact microphone using piezoelectric elements that transmits vibrations directly to the tuner by attaching the microphone to your instrument. The CM-400 enables even more accurate tuning than the microphone on the tuner itself, and allows the instrument to detect its own sound more reliably, especially when practicing with a large group or in other environments where the sound is easily affected by surrounding sounds.
