Designed to enhance the accuracy and isolation of the TM-70T handheld tuner, the black CM-400 Contact Microphone from Korg offers superior tuning performance on a variety of instruments, including wind, brass, and stringed instruments. With its universal rubber-lined instrument clip, the CM-400 delivers faster, more precise tuning.

The Ideal Clip-On Tuner
The CM-400 is a clip-type contact microphone using piezoelectric elements that transmit vibrations directly to the tuner by attaching the microphone to your instrument. The CM-400 enables a 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-Free 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.

Ultrastable Clip
The maximum width of the clip is 1.2", 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.

Not worth purchasing.
Not worth purchasing. Nothing breaks until the insurance is expired.

Get the INSURANCE!!!!
My chair broke. Almost at the one year mark… I’m so glad I got the insurance! I put in my claim (it was easy) and it was resolved within 72 hours. Sometimes I decline the insurance because it turns out to be more hassle than it’s worth but Asurion came through!
