Product Fundamentals
- Compact design for space-saving setups The Boss TU-3S Chromatic Tuner is purpose-built for pedalboards where every inch counts. By eliminating the footswitch it delivers the same trusted tuning performance as the TU-3 in a smaller always-on format. This makes it perfect for compact rigs fly boards or setups that rely on loop switchers like the BOSS ES-8 and ES-5. High visibility in any environment With a bright 21-segment LED meter and a High Brightness mode the TU-3S ensures excellent visibility on dark stages and in bright outdoor settings. This makes accurate tuning fast and easy no matter where youre performing. The optional brightness boost is especially useful during outdoor gigs or festival sets. Flexible tuning options Designed to support a wide range of instruments the TU-3S handles standard guitars 7-strings bass guitars and drop tunings with ease. It includes Chromatic Guitar and Bass modes plus flat tuning capabilities. Accu-Pitch Sign offers clear visual confirmation once tuning is complete streamlining your setup process. Power-efficient and pedal-ready The TU-3S integrates seamlessly into powered pedalboards and requires a PSA-series adaptor for operation as it cannot run on batteries. Its DC Out jack also allows you to power up to seven BOSS compact pedals with an optional daisy chain helping you keep your rig efficient and organised.
