Manufacturer's ID: TU-3S

What we say:

In today's world of ever-bulging pedalboards, it's good to see BOSS paying attention and delivering a super-compact version of their popular TU-3 in the pedal-less form of the TU-3S.

All of the functionality and quality of the TU-3 remains. Since there's no footswitch to turn the tuner on and off, it's always on. It can also still act as a power supply for other BOSS pedals when you use a PSA adaptor and a daisy chain cable.


The industry-standard tuner in an ultra-compact size for pedalboards.
  • Respected TU-3 tuning performance in a more compact size
  • 21-segment LED meter with brightness control
  • High Brightness mode enhances meter visibility outdoors
  • Accu-Pitch Sign function provides visual verification when tuning is complete
  • Chromatic and Guitar/Bass modes, with support for 7-string guitars and 6-string basses
  • Guitar Flat mode supports “drop” tunings up to six semitones below standard pitch
  • Powered by optional PSA-series adapter; DC Out jack for powering up to seven BOSS compact effect pedals via an optional PCS-20A daisy-chain cable
  • BOSS five-year warranty
