BOSS TU-3W Chromatic Tuner Waza Craft

The BOSS TU-3W Chromatic Tuner brings the renowned accuracy and reliability of the TU-3 into the Waza Craft series, giving serious players a premium tuning solution designed for demanding pedalboard setups. Its high-visibility LED meter provides exceptionally clear tuning information, while the TU-3W's refined signal path is designed to preserve your instrument's tone.

The TU-3W offers multiple tuning modes, including Chromatic and Guitar/Bass modes, along with a high-precision tuning display and a built-in output for powering additional pedals. Its True Bypass mode provides a direct signal path when the tuner is disengaged, while the selectable buffered bypass mode offers the traditional BOSS approach for longer pedalboard signal chains.

For players who demand dependable tuning without compromising their signal path, the TU-3W is more than a tuner—it's a professional pedalboard essential.
