The Benchmark Tuner, Enhanced
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.

Extended Functionality
The TU-3W offers many convenient features to elevate your tuning experience. Our innovative Accu-Pitch Sign function speeds operation on stage by displaying a bright streaming indicator when you’ve reached your target. High Brightness mode boosts meter visibility, ensuring easy reading outdoors and in bright environments. And when powering the TU-3W with a PSA-series adaptor,* you can use a PCS-20A parallel cable* to distribute power to other pedals on your board.
