Roadie Tuner

Whether you're a beginner just learning to play guitar, or a seasoned veteran who has seen his share of road gigs, the Roadie Tuner ($80) is just the tool you need to perfect your craft. This automated robotic tuner will literally tune your guitar (or any other stringed instrument with geared pegs) for you, thanks to its sensors that are three times more accurate than the human ear. It will tune your guitar faster than most experienced players, helps you wind and unwind your strings, and will even let you quickly switch between tunings. Use the included iOS app to remember tuning settings, save custom tunes, visualize your tune, and keep track of the quality of your strings.
