Detail 01
CM-400 contact microphone
Attaches directly to the instrument and sends its vibrations to the TM-70.

Independent shopping perspective
The white TM-70 and CM-400 package combines tuning and timekeeping with a contact microphone that mounts directly on the instrument. Rather than relying only on surrounding sound, the CM-400 transfers the instrument’s vibrations to the tuner. An LCD needle meter handles pitch reading, and the metronome supplies an audible pulse for rhythm work. Its pocket-sized format keeps the full setup easy to bring to regular practice or performance preparation.
