The Boss TU-10 Clip-On chromatic tuner is synonymous with reliable, roadworthy and accurate tuning. 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 color” LCD — provides a full, multi-color visual experience not seen before in other clip-on tuners. In addition, the reflection-display function dramatically improves visibility.
