Boss DB-90 Dr. Beat Metronome

The Boss DB-90 Dr. Beat is the most advanced and fully featured digital metronome available, used by professional musicians, recording engineers, and serious piano students who need precise tempo control for high-level practice. The DB-90 includes a built-in microphone mode that detects the acoustic sound of an acoustic piano or other instrument and displays the tempo being played in real time — an invaluable tool for self-assessment of timing. The Tone Coach function plays a reference note at any pitch to assist with sight-singing and pitch training alongside technical piano practice.
