The ProTune is a clip-on tuner with five modes (chromatic, guitar, bass, violin, ukulele) and a high-visibility color display that is easy to read in any lighting. The 360-degree swivel lets you position the screen at the perfect angle on any headstock.

What sets this apart from disposable tuners is the USB-C rechargeable battery, which provides up to 10 hours of continuous use and eliminates the frustration of dead coin cells. It also features an adjustable reference pitch (430-450Hz) and auto power-off to conserve battery. A smart, modern upgrade for your gig bag.
