The world’s top-selling stage tuner, the BOSS TU-2, evolves and improves with the debut of the TU-3.

Housed in a tank-tough BOSS stompbox body, the TU-3 features a smooth 21-segment LED meter with a High-Brightness mode that cuts through the harshest outdoor glare. 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!

Reliable, Easy to Use Tuner


The Boss TU-3 is a simple, easy-to-use bypass tuner that serves it's purpose well. The LED display is easy to read, regardless of your environment/setting. This is a necessary and valuable resource for any guitarist/bassist.

The Next Generation


I love my TU3. Its accurate, reliable, and easy to use. I had the TU2 for years and it was one of the most reliable pedals that I've owned. you want a great tuner that will do the job time after time.

best tuner around


for the money, you can't get a better tuner pedal. you just can't.




Would by it again


Got it before I got into pedal board use. It continues to serve its purpose. However, on a pedal board the location must be considered because of the depress switch. A button switch would make it perfect for the toe tap unless you're using a bypass looper. The cut off for the tuning mode gets me in and out fast. Very easy to read.
