THE LEADING STOMPBOX TUNER, REFINED WITH WAZA EXPERTISE
With the TU-3W, BOSS brings Waza Craft mojo to the world's leading stompbox tuner. At its core, the TU-3W provides rock-solid tuning equivalent to the industry-standard TU-3. In true Waza tradition, the pedal's benchmark functionality is further enhanced with BOSS skill and craftsmanship. Pure, uncolored signal transfer is essential for a tuner, and the TU-3W features redesigned circuitry with selectable buffered or true-bypass operation and the most transparent audio pass-through possible. Packing high-end performance for discriminating players, the TU-3W delivers a premium pedal experience only available from BOSS.

Waza Craft: The Art of Superior Tone
Since the beginning, the engineers at BOSS have been committed to achieving the finest guitar tones using any technology necessary, from old-school analog circuits to high-tech DSP. Continuing this enthusiastic spirit, we are pleased to introduce the Waza Craft series. In Japan, "Waza" is the term for art and technique, and these special edition pedals proudly carry the Waza symbol to represent the pinnacle of BOSS design and craftsmanship. Being made in Japan, the Waza Craft series brings you exceptional tone and touch response through carefully selected analog components, refined circuitry, and meticulous attention to detail.

FREQUENTLY ASKED QUESTIONS

1. What makes the BOSS TU-3W different from the standard BOSS TU-3?

• The BOSS TU-3W is part of the Waza Craft series, featuring premium components and a refined circuit for better tone preservation. It also offers true bypass, unlike the standard BOSS TU-3, which only has buffered mode.

2. What do the switchable true bypass and buffer mode on the BOSS TU-3W do?

• The BOSS TU-3W lets users switch between true bypass and buffered bypass modes. True bypass ensures the signal remains untouched when the pedal is off, while buffered bypass helps maintain signal strength over long cable runs. 

3. Is there a downside to using a buffered pedal like the BOSS TU-3W?

• A buffered pedal preserves signal strength over long cable runs, but it can slightly alter the tone. Some players prefer true bypass pedals to maintain an uncolored signal, while others use high-quality buffers to prevent signal loss. The BOSS TU-3W includes a switchable true bypass mode for flexibility.

4. Can I mute my signal when tuning with the BOSS TU-3W?

• Yes, the BOSS TU-3W has a built-in mute function that silences the output while tuning. This allows for silent tuning without sending any sound to amps, effects, or recording devices.

5. Can I use the BOSS TU-3W for live performances?

• Yes, the BOSS TU-3W is built to last, and its bright, high-contrast LED display ensures clear visibility in various lighting conditions, making it easy to tune accurately even in dark or outdoor environments.

6. Is the BOSS TU-3W good for bass guitars?

• Yes, it works well for bass and accurately tunes lower frequencies.

7. Can I use the BOSS TU-3W with my BOSS RC-300 Loop Station?

• Yes, placing the BOSS TU-3W tuner before the BOSS RC-300 Loop Station in the signal chain (Guitar → BOSS TU-3W → BOSS RC-300 → Amp/Monitor) is recommended. This setup allows for accurate tuning before the signal reaches the looper, ensuring that all recorded loops are in tune.

8. What are the power options for the BOSS TU-3W?

• The BOSS TU-3W can run on a 9V battery or a BOSS PSA-series power adapter, such as the PSA-120S (or a region-specific version). Using an adapter is recommended for extended use.

9. Can the BOSS TU-3W power other pedals?

• Yes, the BOSS TU-3W has a DC output that can power other 9V pedals using a daisy chain cable. However, the total power draw of all connected pedals, including the TU-3W, must stay within the adapter's capacity (500mA for the PSA-120S). 

10. How do I perform a factory reset on my BOSS TU-3W?

• Start by unplugging any cables from the INPUT jack to power off the pedal.

• Next, hold down the MODE button while plugging a 1/4" mono cable into the INPUT jack to power it on. 

• When the green center light appears, press the MODE button within two seconds. The light will flash three times, confirming the reset. 

• If you wait too long without pressing MODE, or if you press a different button, it will remain in its current state without restoring factory default settings. 

• To power off the pedal, disconnect the INPUT cable. To resume normal use, simply reinsert the INPUT cable to power it back on.
