Korg Clip-On Ukulele Tuner HT-U1 -The Headtune is designed with a shape that matches the headstock of typical guitars, basses, and ukuleles. When you play a single note, the built-in piezo pickup will instantly detect the pitch of the vibrating string. Two types of LEDs will light up: a string indicator LED, to indicate the peg location, and an LED meter to indicate the pitch. This makes it obvious which peg you should adjust and how it should be adjusted. Since you can tune your instrument even if you don’t remember the note names of each open string, this makes using the Headtune especially easy for beginners*.
The HT-U1 is the ukulele model, which also detects “Low-G tuning” with the “G” (fourth string) tuned one octave down, supporting solo performances that cover a wide pitch range.
