Chromatic Mode

Chromatic mode is the most versatile tuning mode on the Boss TU-3, capable of detecting notes across the entire chromatic scale. This mode is ideal for tuning instruments with non-standard tunings, such as those using open tunings or alternate tunings. It is also useful for instruments that utilize unusual intervals or microtones.

In chromatic mode, the tuner’s display will show the name of the note being played, along with a visual indicator of whether the note is sharp, flat, or in tune. This comprehensive feedback allows for precise tuning, ensuring that all notes are in their intended positions.

For musicians exploring more experimental tunings or working with instruments that go beyond standard tunings, chromatic mode provides the flexibility and accuracy needed to achieve the desired sound.

Guitar Mode

Guitar mode is specifically designed for standard six-string guitar tuning.

Bass Mode

Bass mode on the Boss TU-3 is tailored specifically for tuning four-string bass guitars, ensuring accurate and efficient tuning for bassists. It simplifies the tuning process by displaying only the notes common to a standard four-string bass, preventing confusion from notes outside the typical bass range. This focused display helps bassists quickly identify and adjust any out-of-tune strings.

Similar to guitar mode, the display will show the note name and a visual indicator of whether the note is sharp, flat, or in tune. This helps bassists quickly identify and adjust any out-of-tune strings.

Using the Boss TU-3

Using the Boss TU-3 is a straightforward process, designed for ease of use by guitarists and bassists of all skill levels. It’s a simple yet effective tool to ensure accurate tuning for your instrument. Here’s a step-by-step guide on how to use the Boss TU-3⁚

Connect your guitar or bass to the INPUT jack on the tuner. This action automatically turns the tuner on.

Press the pedal switch to activate the tuner. The CHECK indicator will illuminate to signal that the tuner is ready.

Play a single note on your instrument and use the tuning knobs on your guitar or bass to adjust the string until the note is in tune. The tuner will display the note name and an indicator that will show if the note is sharp, flat, or in tune.

Repeat this process for each string on your instrument.

Connecting the Guitar or Bass

Connecting your instrument to the Boss TU-3 is a simple process that powers the tuner. The TU-3 features a single input jack for connecting your guitar or bass. This jack acts as a power source, meaning the tuner automatically turns on when you plug in your instrument. The placement of the TU-3 in your signal chain is also important. You’ll generally want to place it at the beginning of your signal chain for optimal performance.

To connect your guitar or bass⁚

Locate the INPUT jack on the front of the Boss TU-3 pedal.

Plug your guitar or bass cable into the INPUT jack.

The tuner will now turn on automatically, and you are ready to begin tuning your instrument.

Turning on the Tuner

The Boss TU-3 is designed to turn on automatically when you connect your guitar or bass to the INPUT jack. This eliminates the need for a separate power switch. However, if you prefer to manually turn the tuner on and off, there is a pedal switch on the top of the unit.

To turn the tuner on manually⁚

Make sure the guitar or bass is not connected to the INPUT jack.

Press the pedal switch once. The CHECK indicator will light up, indicating the tuner is on.

You can now tune your instrument.

To turn the tuner off, simply press the pedal switch again.

The pedal switch also functions as a bypass switch, allowing you to mute the output signal while tuning without affecting your signal chain.

Tuning a Note

Once you’ve turned the tuner on, you can start tuning your instrument. The Boss TU-3 uses a large, clear LED display to show you the pitch of the note you’re playing. The display has a 21-segment meter that lights up green when you’re in tune and red when you’re out of tune.

To tune a note, follow these steps⁚

Select the appropriate tuning mode (Chromatic, Guitar, or Bass) using the MODE button.

Play a single note on your instrument.

Observe the LED meter. If the note is in tune, the center LED will light up green. If the note is sharp, the LED meter will light up red on the right side. If the note is flat, the LED meter will light up red on the left side.

Adjust the tuning peg on your instrument until the center LED lights up green.

Repeat this process for each string on your instrument.

Additional Features

Beyond its core tuning functionality, the Boss TU-3 offers several additional features that enhance its versatility and user experience. One such feature is the ability to adjust the reference pitch, which is the frequency of the A4 note. This allows you to tune your instrument to different standard pitches, such as those used in classical or jazz music. The reference pitch can be adjusted from 436Hz to 445Hz in 1Hz steps.

Another notable feature is the output mute function, which automatically silences the output signal when the tuner is switched on. This is a handy feature for tuning without disturbing others or creating feedback loops.

For guitarists who prefer playing in alternative tunings, the Boss TU-3 offers a Flat Tuning mode. This mode allows you to tune your guitar down by up to six semitones below standard pitch, facilitating the use of various drop tunings.

Flat Tuning

The Boss TU-3 incorporates a dedicated Flat Tuning mode, a feature designed specifically for guitarists who enjoy experimenting with alternative tunings. This mode allows you to accurately tune your guitar down to various flat tunings, ranging from a half step (one semitone) down to a full six steps (six semitones) below standard pitch. This capability is particularly useful for guitarists who explore drop tunings, which involve lowering the pitch of one or more strings to create heavier, more resonant sounds.

To access Flat Tuning mode, simply select the Guitar mode and then press the MODE button once. The tuner will display a “b” symbol to indicate that it’s now in Flat Tuning mode. From there, you can tune your guitar as you normally would, but with the reference pitch adjusted to accommodate the desired flat tuning. This allows you to achieve accurate tuning for various drop tunings, enhancing the versatility of the Boss TU-3 for guitarists exploring different musical styles.

Output Mute

The Boss TU-3 features a convenient Output Mute function that enhances your tuning experience. This feature automatically silences the output signal whenever the tuner is activated, preventing any unwanted noise from reaching your amplifier or other effects pedals while you tune. This is particularly useful in live performance settings where even a small amount of noise during tuning can be distracting.

The Output Mute function is automatically engaged when you turn the tuner on, eliminating the need for any additional button presses or settings. This seamless integration ensures that your sound remains silent during tuning without interrupting your performance flow. Once you’ve tuned your instrument, simply turn the tuner off, and the signal will pass through the pedal uninterrupted, allowing you to resume playing without any delay or sound interruption.

Reference Pitch Adjustment

The Boss TU-3 allows you to adjust the reference pitch, the standard note used for tuning, to accommodate specific musical requirements or personal preferences. This feature is particularly useful for musicians who play in non-standard tunings or who prefer a slightly different tuning for their instruments.

To adjust the reference pitch, press and hold the MODE button or the STREAM/CENT button. The tuner will enter the pitch adjustment mode. The display will show the current reference pitch, which is typically A4 (440 Hz). Use the MODE or STREAM/CENT buttons to cycle through the available reference pitches, ranging from 436 Hz to 445 Hz in 1 Hz increments. Once you’ve selected the desired reference pitch, release the button, and the tuner will return to normal operation. The selected reference pitch will be stored even after the power is turned off.

Troubleshooting

While the Boss TU-3 is generally reliable, there are a few common issues that may arise. If the tuner is not displaying any readings or the meter is not responding properly, ensure that the guitar or bass is properly connected to the INPUT jack. Check the battery connection or the power adapter if using one. If the tuner is displaying an erratic reading, try adjusting the tuning knob on your instrument to see if it stabilizes. If the tuner is consistently showing a false reading, there might be a problem with the tuner itself. Check the user manual for additional troubleshooting tips or contact Boss customer support for assistance.
