Overview The BOSS TU-3 Compact Chromatic Tuner has established itself as a leading choice for musicians, particularly guitarists and bassists, who seek accuracy and reliability in their tuning solutions. Building on the success of its predecessor, the BOSS TU-2, the TU-3 combines the ruggedness expected from BOSS with advanced features that meet the demands of both stage and studio environments. With its compact design and intuitive functionality, this tuner is suitable for musicians of all skill levels.
Key Features One of the standout features of the TU-3 is its 21-segment LED meter, which is designed to provide clear visibility under various lighting conditions. The High-Brightness mode is particularly useful for outdoor performances where sunlight can often obscure displays. This ensures that musicians can tune their instruments quickly and efficiently without straining their eyes.
The tuner supports both Chromatic and Guitar/Bass modes, allowing for precise tuning across a variety of stringed instruments. The ability to tune by string number, especially with support for 7-string guitars and 6-string basses, adds to its versatility. Additionally, the flat tuning capability is a significant advantage for those who frequently experiment with various tunings, as it accommodates drop tunings up to six semitones below standard pitch.
Another impressive feature is the Accu-Pitch Sign function, which provides a visual cue when the tuning is complete. This feature is essential during live performances, as it allows musicians to stay focused on their playing rather than constantly checking the tuner. Furthermore, the TU-3 automatically mutes the output when it is engaged, ensuring that no unwanted sound is produced while tuning.
Who Is It For The BOSS TU-3 is an excellent choice for both amateur and professional musicians. Beginners will appreciate its straightforward operation and clear display, making it easy to learn how to tune an instrument correctly. Intermediate and advanced players will benefit from its advanced features, such as the ability to switch between tuning modes and the option for flat tuning. Additionally, those who perform regularly will find the TU-3's rugged construction and reliability to be invaluable during gigs.
Final Verdict In conclusion, the BOSS TU-3 Compact Chromatic Tuner stands out as a top-tier tuning solution for musicians who value precision and durability. Its range of features caters to a wide audience, making it a versatile tool for any guitarist or bassist. Whether you are tuning on stage or in the studio, the TU-3 delivers exceptional performance that is hard to match.
The BOSS TU-3 is a must-have for anyone serious about their music, ensuring that every note played is perfectly in tune. Its combination of user-friendly features and professional-grade accuracy solidifies its status as a leading tuner in the market today.

What buyers say
5.0 · 5 reviews“Great classic pedal from Boss! Always accurate, Suitable for string instruments, great for live performances.”
“Had this one for ten years before a buzz in the system. Got a new one, same great features, mainly that I can remain plugged in to the PA system and click the pedal to tune without being heard…An Essential feature for my church playing needs. And the leds are real is easy to read from the floor. It also doesn’t seem to care if other instruments are being played while tuning, only cares about my axe. Great pedal!”
“When I'm playing at home, I play with a Peavey Vypyr amp. Those amps have terrible tuners. Never seems to pick up the correct note on my guitar. This tuner is much better. Easy configuration, you can set it for guitar or chomatic or flat steps down, etc. The interface is super easy to read. I personally like the style where it looks like the LEDs are spinning right/left for sharp/flat, but they have the standard off from center tuning that most tuners use. All in all, this is a great tuner pedal, and I'm very happy with it. It does what it does very well.The thing I really like about this tuner is that there is an output and a bypass. Output gets cut when the pedal is active. If you are playing live, this is the one you will want to use. Bypass never gets cut. It's great for at home or if you are tuning somebody else to your instrument. But there's another awesome use for it; you can use it as a splitter and run your signal through 2 amps. This is fantastic for recording. Setting one amp up for the low end and another amp up for the high end and then mixing them together in the studio software makes for a very full sounding recording. If you want to run the same effects, put the tuner last, if you want to run different effects, put the tuner first.”
“I play three instruments in a Americana band. I want to cut the signal while I swap instruments and no feedback while the instruments not being used. The boss delivered, I can switch with no noise and tune on the fly. Great box!”
“Works at advertised, sturdy. Does the bass things with no issues.”
