Use the tuner and metronome simultaneously! The TM-50 – Your partner to help improve and refine your skills as a musician 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. Available in a choice of two colors, black or pearl white, the TM-50 is the perfect daily practice partner that will support your development as a performer. Includes 2 AAA batteries.
