Boss TU-3

The BOSS TU-2, the world's most widely used live tuner, is due for a well-deserved rest and is passing the torch to the TU-3. The TU-3 is also housed in a rock solid BOSS pedal housing. It features a 21-segment LED meter with a "High Brightness" mode, which is clearly readable even in daylight

Choose chromatic or guitar/bass tuner mode and be guided by the "Accu-Pitch Sign" function while tuning. The TU-3 also displays the note names - even for 7-string guitars and 6-string basses

And the Flat Tuning mode allows you to tune your instruments up to 6 semitones lower. Admit it, this is a lot of news under the tuner sun. Simply indispensable for guitarists and bassists!
