It provides ±1-cent accuracy, a C0 to C8 tuning range, adjustable 436 to 445 Hz reference pitch, a 21-segment LED meter, and dedicated chromatic, guitar, and bass tuning modes.\u003c\/p\u003e\n\n\u003cp\u003eDesigned for guitarists and bassists who use switching systems or need to conserve pedalboard space, the TU-3S supports seven-string guitars and six-string basses. Flat-tuning modes accommodate guitar tunings down six semitones and bass tunings down three semitones, while Cent and Stream displays provide two visual approaches to checking pitch.\u003c\/p\u003e\n\n\u003cp\u003eHigh Brightness mode improves LED visibility for outdoor stages, and the Accu-Pitch Sign visually confirms when tuning is complete. The tuner operates from an optional BOSS PSA-series AC adapter rather than batteries. Its DC OUT connection can also distribute power to compatible pedals when used with the appropriate BOSS parallel power cable.\u003c\/p\u003e\n\n\u003ch3\u003eKey
