Korg TM60BK Tuner and Metronome Combo with Clip on Microphone (Black). The best-selling Korg TM series which lets you use a tuner and metronome simultaneously has been revamped. The Tuning and rhythm training are indispensable for brass band or orchestral practice. In addition to letting you use the tuner and metronome simultaneously the TM-60 features a display that is approximately 1.3 times larger than the previous model allowing easy viewing even when the unit is placed on your music stand and also allowing the tuner and metronome functions to both be viewed simultaneously. The TM-60 can detect note names and pitches for a variety of orchestral and other instruments. The range from C1 to C8 can easily be detected. Even acoustic instruments that are difficult to detect because their sound contains a significant amount of low-frequency energy or a large number of partials such as guitar and ukulele can be tuned easily and accurately. By attaching the CM-200 clip on microphone to your instrument the vibrations can be sent directly to the tuner for more accurate tuning. The battery life has also been dramatically improved.
