Boss TU-3S Chromatic Tuner

General

Inspired by the popular TU-3, BOSS now released the compact TU-3S. This stage tuner has the same robust construction as the other TU series stomp boxes, but it has a much smaller footprint without a foot switch. As such, you'll always be able to squeeze this small chromatic tuner onto your pedal board. Just like the TU-2, the TU-3S has a 21-segment LED indicator with a high-brightness setting that allows you to quickly tune your guitar, bass or other string instrument on any dark stage.

TU-3S: accurately tune in standard, flat or chromatic mode

You can choose between chromatic, bass or guitar mode, while the visual Accu-Pitch feature allows for optimal tuning accuracy. The TU-3W can display the name of each note, even those on seven-string guitars and six-string bass guitars, and the Flat-Tuning mode even allows for up to six semitones. Using the optional PSA230 and some patch cables, the TU3W can help power up to seven extra BOSS effect pedals. Finally, as this BOSS tuner is not equipped with a foot switch, it's possible to check your instruments tuning at any moment!
