The Boss TU-3 Chromatic Tuner is an industry-standard, stompbox-style instrument tuner designed for guitars and basses.
Key Features:
Display: A smooth 21-segment LED meter that includes a high-brightness mode for outdoor visibility under direct sunlight.
Accuracy: Precise tuning down to +/- one cent with an Accu-Pitch sign function that visually confirms when tuning is complete.
Modes: Offers Chromatic mode (tuning by note name) and Guitar/Bass mode (tuning by string number, with support for 7-string guitars and 6-string basses), plus a Flat-Tuning mode supporting drop tunings down to six semitones.
Outputs & Power: Features an output that automatically mutes your signal for silent stage tuning, plus a DC output jack capable of daisy-chaining power to up to seven other Boss pedals (when using an optional PSA adapter and PCS-20A cable).
Durability: Housed in Boss's signature "tank-tough" metal chassis built to withstand heavy touring and live performance.
