Chromatic clip tuner for guitar, bass, violin and ukulele. Feature 360° rotatable display with background lighting - this chromatic tuner is perfect for a variety of stringed instruments. Due to its compact design and the clip-on feature, the tuner can easily be attached at the headstock of the instrument. The rotatable 360° LCD display is equipped with a blue light that changes colour to green as soon as the tuning is right. Bright background lighting makes it perfectly readable even on dark stages. Tuning is measured through a vibration sensor which allows you to tune your instrument in noisy situations. This method is much more precise than tuning with integrated microphones. A long battery life is guaranteed through the power saving feature.
