    The industry-standard tuner, Boss TU-3, is now in an ultra-compact size for pedal boards. Scaled down in size, the TU-3S gives you the same industry-standard performance in a tiny footprint that saves precious pedal board space.

    Boss TU-3S Chromatic Tuner Pedal Features
    • 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
    The display and tuning functions are identical to the TU-3—the only thing eliminated is the pedal switch. Always on and ready to go, the TU-3S is perfect for use with pedal switching systems like the Boss ES-8 and ES-5, and ideal for any setup where space is at a premium.

    The TU-3S chromatic tuner is world-standard performance in a tiny footprint!
