Beginner guitarists are almost always frustrated with not knowing how to tune their guitar. Meanwhile, touring musicians spend vital minutes during sets to manually switch their instrument from one complicated tuning to the next. No matter your experience level, tuning can be a chore and take time away from playing. When put on any of the pegs, it analyzes the vibrations from a plucked guitar string to know its current pitch. Then, its motor rotates the peg until it's perfectly tuned. It takes just 30 seconds to tune an entire guitar into any alternate tuning you choose. This process can be easily duplicated to offer musicians of all experience levels the best sound their instrument can produce. With a brand new OLED screen and knob interface, Roadie 2 is now simpler and easier to use. The compact design and powerful hardware can tune electric, acoustic, classical, and steel guitars, 7 and 12-string guitars, ukuleles, mandolins and banjos. Musicians with Roadie 2 can explore new tunings through the 20 presets or by creating custom tunings through the Roadie companion app. The app can also store profiles for all your instruments and help refine your tuning options between each one.
