The Korg TM series allows you to use the tuner and metronome simultaneously. Since this single unit is all you need for both pitch and rhythm training, it has become a favorite lesson tool for brass bands as well as many other types of musicians. The TM-50 is the latest model, featuring a two-level backlight that enhances the visibility of the LCD display. It uses a newly designed needle-style LCD for excellent response, and even greater tuning accuracy. In a first for this series, the entry-level model provides the Sound Back function that allows the speaker to generate the reference tone that's closest to the input sound, giving you a great way to develop and refine your sense of accurate pitch. The TM-50 is the perfect daily practice partner that will support your development as a performer.
