Get to know them!

The BOSS DB-90 metronome packs an astounding number of functions and features into its compact, lightweight chassis. You get four great metronome sounds (including human voice) plus dozens of drum patterns to accompany your playing. Easily customize rhythms with the Note Mixing function for a great variety. Use the built-in mic, MIDI input, and direct guitar input onboard the DB-90 for all types of practice sessions, or plug in your Roland V-Pad and work with the Rhythm Coach function. Finally, users at Sweetwater find the DB-90 easy to use with the adjustable sliders, buttons, rotary knob, and large backlit LCD.

Create different beats to accompany your practice

The Note Mixing function allows you to instantly create a variety of beats by adjusting the levels of five different note values. Front-panel sliders, buttons, and a large rotary dial provide instant, hands-on access to edit parameters. Select four different click sounds, including a human voice-counting sound that will help you know your place in the bar. The DB-90 is also equipped with realistic PCM drum patterns for developing your accuracy and rhythmic feel effectively.

Play along and chart your progress

Plug in a mic, guitar, bass, or V-Drum pads! Drummers can connect to the DB-90 via Roland V-Pads or the internal microphone. Guitarists and bassists can directly plug into the DB-90 without any other gear required and monitor via connected headphones. Practically any type of instrumentalist can benefit from the DB-90's features. If you wish to sync to an external sequencer for a more elaborate accompaniment, you can do so with the DB-90's MIDI input. This stage-oriented feature is especially useful!

Build accuracy, speed, and endurance with Rhythm Coach

Expand your rhythmic horizons with Rhythm Coach. This innovative follow-along feature has four training modes to help build your accuracy, speed, and endurance. With the DB-90's onboard microphone, you can use the Rhythm Coach functions with acoustic drums, or plug a Roland V-Pad into the Trigger input.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
