Boss TU-02 - clip-on chromatic tuner, ideal for guitar, bass guitar, ukulele, and other string instruments. It is small, has a solid construction, and is very easy to use, designed to be positioned on the headstock of the neck. It features a bright colour display visible from any angle, with scale and note display, and two bright indicators that show when the note is flat or sharp, or when it is perfectly in tune. It also allows rotation or adjustment at different angles to provide an optimal position for use and viewing.
Good value for money. It's quite accurate compared to other tuners. It has some useful features, dedicated modes for Guitar, Bass, Ukuleless, Chromatic. The only downside is that it sometimes confuses (oscillates between) the B string and G string, but it corrects itself before the note finishes and indicates correctly. Maybe it's just my tuner, I don't know what to say. It's not a problem for me.
