With the TU-3W, BOSS equips its world-leading tuner pedal with "Waza Craft". Like its counterpart,TU-3, the TU-3W is a highly reliable tuner in pedal garb. However, as befits the Waza tradition, it offers more - just perfectly tuned workmanship. This is noticeable in a natural signal routing, which in the case of the TU-3W is based on revised circuitry with a choice of buffered or "true bypass" operation. The TU-3W is clearly a tuner pedal for demanding musicians who expect the highest quality from BOSS. The world's leading tuner pedal now in the Waza version. Pedal with perfected pitch detection and a high-quality signal buffer. Same tuning functions as the TU-3. Optimized audio circuitry for uncolored signal pass-through. Buffer can be disabled for "true bypass" operation.
