DeadOn: USB-C Rechargeable Clip-On Tuner for Guitar & Bass

What makes DeadOn different from other clip-on tuners? DeadOn combines ±0.5-cent accuracy, a bright color TFT display, USB-C recharging, and a compact 0.63 oz / 18g body, so you get precise tuning without a bulky tuner or disposable coin batteries. Choose dedicated Guitar, Bass, Violin or Ukulele modes, or switch to Chromatic mode for alternate tunings. The adjustable clip and screen make it easy to position the display where you can see it clearly. Can I read DeadOn clearly while tuning? Yes. The bright color TFT display keeps the detected note, string number, and tuning status together in one clear view. Clip DeadOn where it is comfortable to see, pluck a string, and the screen immediately shows whether you are flat, sharp, or in tune. The adjustable display lets you position it for an easy viewing angle on different instruments. Your browser does not support embedded video. Will DeadOn work with my instrument and tuning? Yes.
