BOSS TU-3 Chromatic Tuner Pedal Power Solution Bundle

BOSS is proud to offer the TU-3, a stompbox tuner designed for guitarists and bassists who demand the utmost accuracy. Featuring a high-visibility 21-segment LED meter, the TU-3 tunes to within 1 cent of accuracy and provides visual Accu-Pitch verification. With dedicated modes for chromatic, guitar and bass tuning—supporting 7-string guitars and 6-string basses—the TU-3 is ideal for any instrument.

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. Adjust the brightness to your preference or activate the high-visibility mode for the clearest view of sharp, flat or in-tune readings. 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.

Clean Power and Automatic Muting

In addition to precision tuning, the TU-3 supplies power for up to seven additional BOSS compact pedals. A single connection to your pedalboard's power supply is all that's needed to power the TU-3 and a full effects chain. The tuner also features an automatic muting function, instantly silencing your signal when the tuner is activated for a clean, distraction-free tuning experience.

Rugged and Roadworthy

With a durable metal chassis and footswitches built to last through years of stomping, the TU-3 is perfectly suited for life on the road or in a recording studio. Pick up the BOSS TU-3 at for your most accurate, dependable and versatile tuner yet.
