High-Visibility Meter Ensures Accurate Tuning

Whether on a dimly lit stage or in direct sunlight, the TU-3's 21-segment LED meter is optimized for visibility.

The TU-3's precision tuning circuitry achieves an accuracy of +/- 1 cent so you can tune with confidence at any volume.

Dedicated Modes for Any Instrument

The TU-3 provides Chromatic mode for tuning by note name, as well as Guitar and Bass modes for tuning by string number. Guitar mode supports 6-string guitars, while Bass mode supports 4, 5 and 6-string basses. Seven-string guitarists will appreciate the TU-3's full support for their extended-range axes. Once a mode is selected, the TU-3 automatically detects the pitch of each string as you play it, indicating sharp, flat or in-tune.
