Boss DB-90 Dr. Beat: Overview
The best metronome, by far, is Dr. Beat. While it’s a bit more expensive than others, you’ll see university students and professionals using these all the time.
Dr. Beat is larger than your typical metronome, featuring a sleek, grey casing with various buttons for controlling parameters. I think Dr. Beat is most famous for its voice setting. You can use a robotized woman’s voice to count time.
The front display shows the tempo, voice selection, style, subdivisions, and has a needle for visual aid. The mixing faders below the screen allow you to adjust what notes you hear when it plays — very useful for complicated triplet or sixteenth subdivisions.
The big yellow rotary knob on the right controls the tempo, allowing you to practice very slow BPMs or fast ones.
Rhythm Coach
The Rhythm Coach feature is beneficial for those struggling to keep good time.
By either using the external microphone or by plugging in a Roland V-Pad to the trigger input, you can use the training mode.
Rhythm Coach has four training modes to help your speed, accuracy, and endurance.
Verdict
I love my Dr. Beat — it’s been an essential component of my practice routine over the years. I can’t recommend one more if you’re learning percussion and drums.
