The TU-3W Waza Craft takes the world's most trusted pedalboard tuner and upgrades it for tone purists. The big addition is the switchable true bypass mode alongside the improved buffered output. In buffer mode, a premium-quality buffer preserves your guitar's high-end clarity across long cable runs and complex pedalboard chains. In true bypass, your signal passes through completely unaltered when the tuner is off.

Tuning accuracy and the bright 21-segment LED meter are the same as the standard TU-3 -- fast, precise, and visible under stage lights. You still get the DC output for powering other pedals and the same tank-tough Boss enclosure. The difference is purely about signal integrity, and for players with large pedalboards or those who are particular about their clean tone, that difference is real. It's the definitive version of the world's most popular tuner.
