Whether you are an acoustic, electric, or bass guitar player, you will find the Snark SN-RE Rechargeable Tuner to be an invaluable asset in your music toolbox. Thanks to a USB-rechargeable design, you can forget about the hassle of replacing batteries. The clip-on tuner retains the charge for weeks and even months depending on how often you use it. The tuner features a fast, accurate display on its LED screen. The jaws of the clip are reinforced with vulcanized rubber joints, so they will grip your headstock tightly but without scratching it. The Snark SN-RE features a 360° rotating arm that makes it easy to adjust the tuner to the right angle.
