A great lesson and practice tool, the TM-40 offers both tuner and metronome functions simultaneously or independently. Its large LCD-type needle delivers both the accuracy of an LCD and the excellent visibility of a needle indicator. It also has LED indicators that show pitch deviation or blink to indicate the tempo, making the TM-40 a highly visual tool.
