The new Gear Buddy GB23 clip-on chromatic tuner is our favorite tuner, because it's small, affordable, and accurate. It's easy-to-use, and clips to your instrument quickly and safely, without marking the finish.
The LCD display rotates 360 degrees and tilts more than 90 degrees so you can position it right where you need it. The display is also easy to see, and turns from blue to green when you acquire the correct note.
The one-button on/off switch lets you select between five different tuning modes: chromatic, guitar, bass, violin, and ukulele. The clip has ample padding on top and a swivel base.
