Boss TU-3 Specification

The Boss TU-3 is a chromatic tuner pedal renowned for its precision and durability, widely favored by musicians for both live performances and studio sessions. It features a robust design that ensures reliability under rigorous conditions. The pedal boasts a high-brightness LED meter with a 21-segment display, providing exceptional visibility even in bright outdoor settings. It supports both chromatic and guitar/bass tuning modes, accommodating a range of tuning preferences. The TU-3 allows for flat tuning up to six semitones below standard pitch, catering to players who use down-tuned instruments. A noteworthy feature is the Accu-Pitch Sign function, which audibly confirms when tuning is complete, enhancing tuning accuracy and convenience. The pedal also includes a bypass mode that maintains a pure signal path when not in use, ensuring tonal integrity. With a tuning range from C0 (16.35 Hz) to C8 (4186 Hz) and a precision of ±1 cent, the TU-3 provides exceptional accuracy. It is powered by either a 9V battery or an optional AC adapter, offering flexibility for different performance setups. Additionally, the pedal can power other pedals in a chain when using the AC adapter, making it a versatile choice for complex pedalboard configurations. Its compact dimensions and sturdy construction make it a practical and enduring tool for musicians seeking reliable tuning solutions.

Boss TU-3 F.A.Q.

How do I calibrate the Boss TU-3 tuner for different tuning modes?

To calibrate the Boss TU-3, press and hold the MODE button to cycle through the available tuning modes (Chromatic, Guitar, Bass, etc.). Once the desired mode is selected, you can fine-tune using the CALIB button to adjust the reference pitch from 436 Hz to 445 Hz.

What should I do if the TU-3 does not power on?

First, ensure that the power supply is connected correctly and providing the correct voltage. Check the 9V battery if you are using battery power. Replace if necessary. Also, inspect the power input jack for any debris or damage.

How can I use the Boss TU-3 to tune my guitar silently during a live performance?

To tune silently, connect your guitar to the TU-3 and run a cable from the output to your amplifier. Engage the pedal, which will mute the output signal, allowing you to tune without sound being output to the amp.

What is the difference between the TU-3's 'Stream' and 'Cent' modes?

Stream mode displays tuning in a moving LED pattern that slows down as you approach the correct pitch, while Cent mode uses an LED needle to indicate pitch accuracy directly. Both modes help you achieve precise tuning.

How can I ensure the TU-3 is accurate when tuning my bass guitar?

Ensure that the TU-3 is in Bass mode by pressing the MODE button until "Bass" is displayed. This setting optimizes the tuner for bass frequencies and enhances tuning accuracy for bass guitars.

What maintenance steps are recommended for the Boss TU-3?

Regularly check the pedal for any loose connections or wear on the input/output jacks. Clean the exterior with a soft, dry cloth. Avoid exposing the pedal to extreme temperatures or moisture to maintain its longevity.

How do I replace the battery in the Boss TU-3?

To replace the battery, press the latch on the base of the pedal to open the battery compartment. Remove the old 9V battery and replace it with a new one, ensuring the correct polarity. Close the compartment securely.

Can the Boss TU-3 be used with a power daisy chain?

Yes, the Boss TU-3 can be powered using a daisy chain power supply. Ensure that the total current draw of all connected pedals does not exceed the power supply's amperage rating to prevent overload.

How do I troubleshoot if the TU-3 is not detecting certain strings?

Check that the TU-3 is set to the correct tuning mode for your instrument. Ensure that the guitar's volume is sufficiently high and that strings are not muted or dampened. Inspect the input jack and cable for proper connection and functionality.

What should I do if the TU-3's display is not working correctly?

If the display is malfunctioning, first check the power source to ensure it's adequate. Inspect for any visible damage to the display. If issues persist, consider contacting Boss support or a professional technician for repair.
