The Roadie Automatic Guitar Tuner ($80) works with a smartphone to automatically tune your guitar, quickly and accurately. The Roadie takes the worry out of tuning and allows artists to spend their time learning and enjoying their instruments. The Roadie works by pairing with a free app that you load into your iOS or Android device. Just turn on the mobile app and place your smartphone near the guitar. Place Roadie onto your guitar peg, strum the string and let Roadie do the rest. Roadie works with electric guitars and offers many more features.
