The TU-3 newly incorporates a "High Brightness Mode" to improve visibility outdoors. In addition, 21 LEDs are used in the meter section to smoothly display the tuning status. Comfortable and smooth tuning can be performed on various stages. ■The tuning display pattern can be switched not only to "CENT," which is based on a needle-type meter, but also to "STREAM," which expresses the pitch's rise and fall with a flow of light, which was popular in the TU-2. Of course, in addition to "Chromatic," which allows you to check the note name in semitone increments, it also features "Guitar Mode/Bass (5-string bass compatible) Mode," which can be displayed by string number. ■The TU-3 newly features the Accu-Pitch Sign function, which uses the movement of LEDs to notify you when tuning is complete. You can tune with peace of mind and comfort. Furthermore, the flat tuning range has been expanded, supporting up to 6 semitones in Guitar Mode and 3 semitones in Bass Mode. Of course, it also features convenient functions such as power supply to other compact pedals and an OUTPUT terminal that automatically mutes the signal when the tuner is turned on, allowing you to tune without producing sound.
