B07ZRK97BT Soundbrenner Core | 4-in-1 music tool for musicians | Vibrating metronome, Chromatic contact tuner, Decibel meter and Watch | For multiple instruments (guitar, bass, violin, ukulele)

4 TOOLS IN 1: Everything you need is right there with you! A vibrating metronome, contact tuner, dB meter, and smartwatch in one device.
VIBRATING METRONOME: Get rid of the annoying audible click and feel the beat with vibrations 7x stronger than a typical phone. Customize time signature and subdivisions, create accents to the right note directly on the Core.
CHROMATIC CONTACT TUNER: Detach the Core from its bezel and connect it directly to your musical instrument. With an easy interface and LED ring display, the Core can guide you to perfect pitch of most instruments.
DECIBEL METER: Protect your ears by being aware of your surrounding sound levels. The Core will alert you when the volume exceeds harmful dB thresholds.
SMARTWATCH: View time, date, and notification directly on the Core. You can also accept or reject calls within a push of a button.
