Waza pedals are made in Japan and represent the pinnacle of BOSS design and craftmanship. The TU-3w features the same tuning functions of the industry-standard TU-3, but they've re-engineered the audio circuitry from the ground up. The TU-3w, when not engaged as a tuner, acts as a premium signal buffer. The buffer is switchable, so the pedal can run in true bypass as well. We're also including a FREE patch cable and 9v power supply.
