D'addario Ct-17 Eclipse Clip On Chromatic Guitar Tuner - Blue

When you need fast, precise tuning on stage or in the studio, the D'Addario Eclipse CT-17 Clip-On Chromatic Guitar Tuner in Blue delivers reliable performance in a discreet, portable package. Designed by musicians for musicians, this clip-on tuner reads vibrations from the neck for accurate tuning without plugging in or competing with room noise.

The Eclipse CT-17 offers a full-color vertical display that remains easy to read from multiple angles, even under bright stage lights.
