With its ultra-precise tuning accuracy and stylish, compact, durable design, the TU-10 is a must-have addition to any case or gig bag. The impressive true colour LCD dramatically improves visibility in any lighting condition, and makes tuning simple, with the current pitch shown simultaneously via a streaming meter display, flat/sharp arrow indicators, and a note-name readout.

The TU-10 also has a monochromatic mode, which turns off the backlight and doubles the battery life. To help users tune even more quickly, the TU-10 incorporates BOSS’ proprietary Accu-Pitch® function, which displays a positive visual confirmation when the correct pitch is attained.

The Boss clip on tuner is a popular choice for guitarists who want to have a clip-on tuner and trust the Boss name in terms of tuning. It is designed to be easy to read in various levels of lighting.

Its Boss quality and Boss ease of use in an easy to use clip on pedal -  A great combination!

Clip-On Tuner with “True” Colour Display

The BOSS “TU” line is synonymous with reliable, roadworthy and accurate tuning. Today, the world’s most famous tuner prefix gets “clipped-on” with the debut of the TU-10. Reinventing the traditional image of clip-on tuners, the TU-10 offers a stylish design and robust body with high-performance features derived from other BOSS tuners, such as Accu-Pitch, flat tuning up to five semitones, and Stream mode. A unique feature — the “true colour” LCD — provides a full, multi-colour visual experience not seen before in other clip-on tuners. In addition, the reflection-display function dramatically improves visibility.
