Many guitar tuners have graced the pages of The Gadgeteer over the years, but the Roadie is possibly the new benchmark and the only one you’ll want in your gig bag. It is a Kickstarter-funded creation that pairs a handheld auto tuner–the Roadie device itself– with a corresponding mobile app. With the app you can save particular tuning schemes as well as save different instrument profiles. Once the Roadie is attached to a tuning peg, simply strum, and it will begin turning the peg automatically until it reaches the selected note from the app. The app can also store information on the string quality, suggest when to restring, and keep instrument maintenance records. Roadie is compatible with electric and acoustic guitars, banjos, ukeleles, and any other instrument with guitar machine heads (it does not work on wooden pegs). The Roadie automatic guitar tuner is currently available for $99.
