No matter what genre you play, every guitarist needs a reliable tuner, and the TU-3 is one of the best on the market.

    Perfect fit for my pedalboard. Easy to use too.

  • Great tuner....

    Great, spot on strobe tuner at an affordable price. Almost as good as having a Peterson in a foot pedal!

    If you are a musician, you know what this does...and you know you can’t do your job without it. Boss undoubtedly makes the most accurate and reliable tuner on the market for the working musician. Brighter LEDs on the TU-3 is the only reason my very road worn TU-2s have all gotten a well deserved retirement.
