Turning your guitar and other string instruments is a lot easier when you have an automatic tuner around. The Roadie 4 is the latest generation automatic guitar tuner, with a built-in winder and 3 speed settings. It has a 1.9-inch full-color LCD screen with 170 x 320p resolution. It is compatible with almost all string instruments with geared pegs and has over 150 built-in tunings.

This gadget also has a metronome. It comes with Bluetooth connectivity for syncing. The companion app lets you log each string change. The app tracks when you changed your strings and when you should do so again. It also lets you add other instruments like charango. Roadie 4 lets you create custom tunings.
