CHROMATIC TUNER 'The TM series, an innovative concept of combined tuner and metronome, features a wide variety of functions and exceptional visibility, and is the ultimate in tuning and rhythmic training for wind and string instruments.
The latest model, the TM-70T, further elevates the original concept by making it easier to use than ever. Not only is it small enough to fit in a pocket, but it features a new display with improved visibility and a new transposition function (F, Bb, Eb), making it the ideal companion for any musician. The sound quality of the metronome and sound output has also been improved to make it easy to hear even in noisy environments.
The quality, speed and accuracy of tuning, which is essential for any performance, has also been improved.
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 world of tuners/metronomes for many years.
