Korg TM-70C Combo Tuner Metronome
 
CM400 Contact microphone is included with this unit.
 
Complete functionality in a compact body. The TM-70T, the long-awaited tuner and metronome combo is here.
The TM series, a ground-breaking concept of a combined tuner and metronome, boasts a wide variety of functions and outstanding visibility and is the ultimate tuning and rhythm training item for wind and string instruments.
The latest model, the TM-70T, further elevates the original concept making it easier to use than ever. It is not only small enough to fit in a pocket, but features a new display with improved visibility, and a new transpose function (F, Bb, Eb) , making it the ideal partner for any musician. The sound quality of the metronome and sound out has also been enhanced so that it is easy to hear even in noisy environments.
The quality, speed and accuracy of the tuning, which is essential to every performance, has also been enhanced.
The TM-70T is completely "Made in Japan", which is a testament to Korg's pride and commitment to quality as a leader in the tuner/metronome world for many years.
