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.

Made in Japan, the TU-3W is the ultimate stompbox tuner for professional players and pedal enthusiasts. At its core, it preserves the high-accuracy tuning performance and extended functions that have made the BOSS TU series a worldwide standard for decades. This special model also includes enhanced buffer circuitry to drive your entire rig with strong signal conditioning and ultra-clear sound. When using wah, fuzz, and other pedals that can be sensitive to signal buffering, it’s easy to disable the buffer via a rear-panel switch.

Key Features:

• Gold standard pedal tuner enhanced with Waza craftsmanship
• Refined buffer circuitry for exceptionally pure signal pass-through

• Tuner automatically mutes when the tuner is on
• DC output jack for distributing power to other pedals (requires optional PSA-series adaptor and PCS-20A parallel cable)
