Even the best portable guitar isn’t worth hauling around if you can’t keep it in tune. Sure, you could download an app onto your phone and fiddle with the screen on your knee, but wouldn’t it be easier and less disruptive to clip a tuner on to your guitar? This KLIQ UberTuner literally feels the vibrations on your guitar to detect pitch rather than using a traditional microphone, so it’s easy and accurate even in noisy environments. With its large display and bright screen you’ll never have any doubt where you stand, and its swivel head tilts and conforms to your preferred viewing angle. It’s got dedicated modes for guitar, bass, violin, and ukulele.
