Tired of fidgeting with displays and trying to get into tune playing a show at the noisiest bar on the planet? the Roadie Automatic Guitar Tuner is three times more sensitive than the human ear and automatically adjusts knobs within a detection range of A1 (55Hz) - A5 (880Hz). An accompanying app gives you instant access to eight alternative/open tunings, and to top it all off, the Roadie gets you lightning-fast restrings with a motor capable of 70 RPM.
