Simply connect Roadie to the tuning peg, strum the string, and watch Roadie get it into perfect tuning in a few seconds.
The accompanying mobile app comes preset with 8 alternate and open tunings. It also gives you the ability create your own custom tunings. If you like to tune a string slightly sharp or flat or if you have a piece you like to play in a different temperament, simply adjust that tuning in the app. The reference A 440 Hz pitch is customizable in 0.1 Hz increments from 420 Hz to 460 Hz.
When you need to change your strings, Roadie Tuner will help you unwind and wind your strings quickly and hassle-free using buttons on the app or a rocker switch on the side of Roadie itself.
