With its versatile features and exceptional visibility, the TM Series continues to be a best-selling product for tuning and rhythm training on tubes, stringing instruments. The newest model TM-70F has even been able to make the body smaller. While it is sized to fit in your pocket, it also has a new focus mode for improved visibility and improved tuning accuracy. The metronome and sound out will also power up the sound of the metronome and sound out so you wont be buried by the sound around you. In addition, since the tuning is the basic of performances, the quality has been strengthened, and the production site has changed from TM-70 to Japan. The "Made in Japan" name is a sign of pride and commitment to quality that Corg has been towing the tuner/metronome scene for many years.
