The Boss Dr. Beat DB-90 Talking Metronome is a versatile music practice and teaching tool that can serve both as a 21st century replacement for swinging pendulums and as a great introductory gadget.
The DB-90 mixes traditional metronome functions, including 30 kinds of beat patterns and a 30-250 tempo with features like its “Rhythm Coach” exercises to keep you matching the beat.
The unit features a MIDI input and 1/4-inch headphone and input jacks with amplifier simulating, meaning you can plug your guitar into the Dr. Beat directly, and it will act as a monitor for you. There’s no MIDI output though, so you won’t be sending any data back to your computer/workstation/etc.
The DB-90’s “tap” feature lets you choose your own tempo without having to dial in to a pre-programed setting. After all, it’s your music.
The unit’s default power supply is a 9-volt battery, but we’d recommend buying the Boss PSA DC power adapter to save on batteries.
It’s a big device, but it has all the practice and tuning features you could imagine. It’s a perfect solution for any musician.
