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

  • Great tuner....

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

    i have been told in the past that this was THE tuner, to be honest in never thought i would be as happy as i am for a tuner, but it is just great, a must have indeed!

    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.

  • Classic, what's not to like?

    Yeah, it takes up space, but it also lets you connect power to another pedal and it eliminates the need for a buffer at the beginning of your pedal chain. (A concept TC Electronics picked up on with their latest tuner.)
