Boss is often one of the first brands that comes to mind when guitarists think about chromatic tuning pedals. Now, the tech and usability of the TU-3 has been packaged into an even smaller and more pedalboard-friendly enclosure for those players with even less room to spare. Refusing to compromise on functionality, the only sacrifice TU-3S users have to make is with the footswitch, which this smaller unit doesn't include. Otherwise, the display and tuning functions remain the same from pedal to pedal.

    small footprint & good visibility. 9v power out on the back of the pedal is really handy. I bought a used tu-3s and it's super high quality. i'd have no problem getting pretty much any used boss pedal so long as nobody's driven a screwdriver through it

    Perfect, easy, clean, does it’s job well. Love that I don’t have to press any buttons. You need to have the volume up on your guitar so the tuner gets your signal. Volume pedal and you’re good!

  • Boss quality with a smaller foot print, excellent display
