As a chromatic tuner, the CM40 offers a variety of impressive features, including two modes of tuning: Tone (manual) and Tuner (automatic). When using Tuner mode, the tuner automatically recognizes the note you’re playing, while Tone mode allows you to select a reference pitch. Use its onboard microphone to adjust acoustic instruments and its 1/4" input connector for electronic instruments. No matter what mode you use, the CM40 allows a wide range of calibration from A430-450Hz, while its smooth, real-time display provides precise and accurate tuning. It also features a transposition setting that allows you to easily tune down your instrument.

The CM40 also functions as a metronome. Practice along with tempos ranging from 30-250bpm using the tuner’s built-in speaker with volume control and 1/8" headphone jack. In Beat mode, you can choose from ten different time signatures. And by using the Rhythm function, each time signature contains nine rhythm variations for practicing a wide range of styles. You will master your timing, no matter the time signature or style of music you’re playing.
