Convenient and unobtrusive, the LT-21 multi-function clip-on tuner helps ensure your instrument is always in tune, even on dark stages. It handles noisy environments with ease thanks to its built-in vibration sensor. The LT-21’s dual-hinge design allows you to mount the tuner on either side of your instrument’s headstock. The LCD display’s easy-to-read needle indicates how close to pitch each note is, and moves to the center of the display once the note is in tune.
