Rock-Solid Tuning Performance

With its large display and easy-to-set controls, the TU-03 makes instrument tuning quick and efficient. Standard chromatic mode allows you to tune to any pitch, while dedicated guitar, bass, ukulele, and violin modes provide string-based displays for even faster operation. Flat and double-flat tunings are supported as well, and the overall reference pitch is adjustable from 430-450 Hz. The reference pitch can also be sounded through a built-in speaker, providing an audible tuning tone for your playing partners.

An Onboard Metronome to Improve Your Time and Groove

Good rhythm is a vital skill for every musician. And since the TU-03 mounts right on your instrument, it’s never been more convenient to stay on top of your timing practice. You can hear the metronome beat with the integrated speaker, and also follow along visually with the dynamic display. It’s even possible to turn down the metronome sound and use the display as a silent timing reference while rehearsing and performing with other musicians. Eight different patterns and ten beat variations support practicing numerous styles and time signatures, and the tempo is easily adjustable from 30-250 BPM.

Always at the Ready

The TU-03 is rugged, reliable, and built to last, with a spring-loaded clip and flexible pad that provides secure, stable attachment on all types of headstocks. And thanks to its integrated backlight and non-glare surface, the display is easy to view in any environment, from dark stages to bright sunlight.
