The BOSS "TU" line is synonymous with reliable roadworthy and accurate tuning. Today the worlds 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.
