The new Korg TM-40 is a digital metronome that combines the accuracy and advanced features of Korg's world-famous music products into a single, compact and easy-to-use unit. A great lesson and practice tool, the TM-40 offers both tuner and metronome functions that can be used simultaneously or independently. A large LCD-type needle delivers both the accuracy of an LCD and excellent visibility of a needle indicator. The metronome tuner also has LED indicators that show pitch deviation or blink to indicate the tempo, making the TM-40 a great visual tool. With a detection range of C1- C8, the TM-40 provides quick and accurate coverage of a wide spectrum of notes and pitches for wind, string, keyboard and most other acoustic instruments, including guitar and ukulele.
