Combining a high-precision chromatic tuner with a fully featured metronome in a single compact body, the Korg TM-70C is the latest evolution of the long-running TM series — a concept that has made simultaneous tuning and rhythm practice accessible to musicians of all disciplines. The TM-70C builds on this heritage with an improved LCD needle display, enhanced sound quality, and a new transpose function that makes it more versatile than ever.

Wide-Range Chromatic Tuner

The tuner detects pitches across the full range of C1 to C8, making it suitable for any instrument from double bass to piccolo. The LCD needle meter provides excellent sensitivity and visibility, giving players a clear, immediate reading of their tuning accuracy. Calibration can be adjusted to various concert pitches, and the transpose function allows musicians to tune transposing instruments without mental calculation.

Versatile Metronome

The metronome covers a wide tempo range from 30 to 252 beats per minute with 15 rhythm variations, supporting everything from slow practice to complex rhythmic patterns. Sound Out and Sound Back modes add flexibility for different practice scenarios, and both tuner and metronome functions can be used simultaneously for coordinated intonation and timing work.

Practical Design

Long battery life of up to 250 hours keeps the TM-70C ready for extended practice sessions or touring use. Convenient memory backup retains settings between sessions, and an auto power-off function conserves battery life during breaks. The compact, pocket-friendly format makes it easy to carry to rehearsals, lessons, or the stage.
