What we say:

BOSS's perennial favourite tuner, the TU-3, is the latest incarnation of a unit that has been the fundamental centre of thousands of rigs over the last few decades.

Apart form accuracy (this one is within one cent), there isn't much you need a tuner to have but there are a few important features. Visibility is one and the TU-3 gives you a strong visual reference with a 21 segment LED that can be super-bright (you can dial that back if it's too much!) and easy to work with on a dark stage.

Other useful features include modes for Guitar and Bass, (including 7 string guitars and 6 string basses), modes for drop tunings by the semi-tone, an automatic signal mute when the pedal is engaged and, rather excellently, it behaves like a power supply for other pedals if used with a PSA power supply and daisy chain. Much more, then, than just a great tuner.


Choose between Chromatic or Guitar/Bass tuning modes, and enjoy visual pinpoint tuning verification with the Accu-Pitch Sign function. The TU-3 incorporates a convenient Note Name Indicator that can display notes of 7-string guitars and 6-string basses, while the Flat-Tuning mode can support up to six half-steps. It’s the new-standard tuner that no guitarist or bass player should be without!
  • 21-segment LED meter with brightness control

  • Accu-Pitch Sign function provides visual verification when tuning is complete
