Used and in excellent condition, the BOSS TU-3 Chromatic Tuner Pedal is a reliable and essential tool for any guitarist or bassist. Housed in BOSS's legendary tank-tough casing, the TU-3 features a high-brightness 21-segment LED meter with a High-Brightness mode ideal for outdoor use. It offers both Chromatic and Guitar/Bass tuning modes, including support for 7-string guitars and 6-string basses, as well as flat tuning up to six semitones. The pedal mutes the output when tuning for silent adjustments and includes a built-in power supply function to power up to 7 other pedals (with optional PCS-20A cable). Whether you're rehearsing or hitting the stage, this pedal ensures quick, precise tuning every time.
