Thank you for viewing. This is a BOSS TU-3W. I purchased it used and have been using it on my board for live performances and rehearsals for about 3 years. There are minor scratches on the main unit, and Velcro is attached to the back. (Please check the product photos.) Therefore, I am selling it at a special price. Power-on and operation have been confirmed, and the bypass switch is working without any problems. Please note that this is a used item, so no returns or exchanges are accepted. Below are the details of the product. ■ Guitar/Bass Tuner, WAZA CRAFT ■ A world-standard pedal tuner infused with the spirit of WAZA CRAFT. ■ Combines the renowned tuning and a premium buffer in one pedal. ■ The world-standard tuning functions are inherited directly from the TU-3. ■ The audio circuit has been redesigned to achieve purer signal transmission than ever before. ■ Supports switching between buffer and true bypass. ■ Comes with a reassuring 5-year warranty.
