KORG TM-70C BK - Tuner and Metronome Combo with Contact Microphone (Black)

The Korg TM-70C BK is the package that combines the TM-70T —chromatic tuner and metronome in a single unit— with the CM-400 contact microphone in a matching black finish. This combination allows for fast and accurate tuning even in noisy environments: the CM-400 is attached to the instrument and transmits the vibration directly to the tuner, avoiding interference from ambient sound. The TM-70T incorporates a highly sensitive needle-type LCD meter , simultaneous use of tuner and metronome, transposition for instruments in F/B♭/E♭ , pure thirds markings for playing in tune together and a complete metronome with 30–252 BPM , three tempo adjustment modes and 15 rhythmic variations . With a C1–C8 detection range (≈ 32.70–4,186 Hz), very long battery life and a foldable stand for placement on the music stand, it is a compact, robust and “ Made in Japan ” solution for students and professionals.
