A BOSS Tuner and Metronome to Progress Daily
The Boss TU-30 is designed as a simple, precise, and reassuring practice companion, whether you are a student, teacher, or stage musician. Its BOSS-style tuning offers clear reading via the LCD screen and LED tuning guide, while the Reference Note function also allows ear intonation checks, useful for music education and ear training. On the rhythm side, the metronome offers several styles (including clave and triplets) and a wide tempo range to build your timing, practice sixteenth notes, or lock in a groove during rehearsal.
