The Roadie 3 is an automatic tuner for almost any stringed instrument with geared pegs. Pop it onto the tuning peg, pluck a string, and it listens through vibration rather than a microphone, then turns the peg until the string is in tune.
It works well in noisy spaces like rehearsal rooms, gigs or jam sessions, and comes loaded with over 150 alternate tunings for quick swaps between standard, open, drop and more experimental setups.
