Korg CM400 Contact Microphone - White

Continue Shopping or Checkout

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 tuner to detect the instrument’s pitch more reliably, especially when practicing with a large group or in other environments where the signal is easily affected by other sounds.

Durable, Disconnection-Resistant Cable
The cable, which excels in efficient sound transmission, is made of a material with a soft and flexible wire sheath. The split shape of the joint between the clip and the cable reduces the load on the wire and makes it difficult for the cable to break.

Stable 3.5mm mini-plug
The output terminal for connection to the tuner body has a 3.5mm mini-plug, designed to work with with the TM-70T.

Clip section for stable attachment to various instruments
The maximum width of the clip is 30mm, and the inner rubber part is designed to be attached to any instrument without leaving any  mark or causing any damage. It can be attached easily and securely to a variety of instruments, such as the bells on wind instrument, the heads of bowed string instruments (such as a violin), guitar, bass and ukulele heads, and more.
