New! This 3 in 1 tuner, metronome and tone generator has it all. Keep your Mandolin in tune. LED lights let you know if the pitch is flat or sharp. Runs off of two AAA batteries. Measurement range 27.5 Hz to 1760.07 Hz. The wide range is to reach all the the high and low notes.

Stay intempo with the built in metronome. The metronome can generate quarter note, eighth note, triplets, and sixteenth note clicks at tempos anywhere from 30-250 beats per minute. The beats are both audible and represented on the digital display.

If you feel more comfortable tuning by ear, you can use the tone generator function. You can generate one whole octave of notes through the built in speaker or the headphone jack.
