Tax excluded. Shipping calculated at 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.

  • Clip on mic for increased tuner accuracy
  • Durable cable to reduce wear
  • 3.5mm plug for use with TM70 T
  • Wide mouth of clip for easy attachment to most instruments
  • Strong rubber on the inside of clip for secure attachment
