Convenient Functions
The Boss TU-3 is packed with convenient features designed to enhance the tuning experience. One notable feature is the high-brightness mode, which significantly increases the LED meter’s visibility, particularly in dimly lit environments.

Troubleshooting
While the Boss TU-3 is a robust and reliable tuner, occasional issues can arise. Here are some common troubleshooting steps to resolve any problems you may encounter⁚
If the tuner is not powering on, ensure that the input jack is securely connected to your instrument. The TU-3 is powered by the instrument’s signal, so a loose connection can prevent power from reaching the unit. If the problem persists, try a different instrument cable.

Buffer Feature
The Boss TU-3 incorporates a built-in buffer, a crucial feature that maintains the integrity of your guitar’s signal while ensuring optimal performance. A buffer acts as a signal amplifier, preventing signal loss and preserving the high-frequency tones that can be lost when passing through long cable runs or multiple pedals.

When High Brightness Mode is activated, the tuner’s LED display illuminates with a significantly increased intensity. This increased brightness allows for clear and accurate readings, even in dimly lit environments or under harsh stage lighting. The tuner’s display becomes easily visible, allowing you to tune your instrument with precision, regardless of the surrounding lighting conditions.
To activate High Brightness Mode, simply press and hold the MODE button for a few seconds. The display will cycle through various settings, and when High Brightness Mode is selected, the tuner’s display will become noticeably brighter. Once activated, the High Brightness Mode remains active until you switch it off by pressing and holding the MODE button again.
