KORG Headtune HT-U1 - Clip-on Ukulele Tuner with String Indicator and Auto Power Off

The KORG Headtune HT-U1 is a clip-on chromatic tuner designed specifically for the ukulele . Its shape mimics the instrument’s headstock, and when you clip it onto the headstock, two LED indicators work together: one indicates which string you’re tuning (based on the headstock position), and the other shows whether the pitch is low , high , or in tune . It offers ±1 cent accuracy , a 12-note chromatic scale (A4 = 440 Hz) , and an optimized range for standard G–C–E–A ( G3–A7 ) ukuleles, as well as support for the popular Low-G tuning (with the fourth string tuned an octave lower). It runs on a single CR2032 battery with a battery life of approximately 35 hours , and features an auto-off function after about 10 minutes of no signal to conserve battery life. Its tilting head offers up to 120° of adjustment for comfortable reading in any position, while maintaining an ultra-compact format of 54 × 24 × 35 mm and only 18 g in weight.
