■The TU-3 is the successor to the TU-2, a tuner ideal for live performances, featuring the same design as the BOSS Compact Series. The TU-3 also features a new ""High Brightness Mode"" for improved visibility outdoors. The meter section also uses 21 LEDs to smoothly display the tuning status, allowing for comfortable and smooth tuning on any stage.
■ The tuning display pattern can be switched between ""Cent,"" which is modeled after a needle meter, and ""Stream,"" which, as popular on the TU-2, uses a stream of light to indicate pitch. Of course, tuning is available in ""Chromatic,"" which allows you to check the note name in semitone increments, as well as ""Guitar Mode/Bass (compatible with 5-string bass) Mode,"" which displays the pitch by string number.
■ The TU-3 features a new AccuPitch Sign function, which uses LED movement to indicate tuning completion, allowing for safe and comfortable tuning. Furthermore, the flat tuning range has been expanded to support up to 6 semitones in guitar mode and 3 semitones in bass mode. Of course, it also comes with convenient features such as power supply for other compact devices and an OUTPUT jack that automatically mutes the signal when the tuner is turned on, allowing for silent tuning.
