NAME: Roadie Tuner
WHAT DOES IT DO: 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.
HOW MUCH: $80
FUN FACT: Yes - it tunes it for you!
