Roadie 4

One tuner for all geared pegs. The Roadie 4 has redefined what a tuner can do. Unshaken by noise, unmatched in speed - ready for any tuning, anytime.
* Pro-Level Speed and Precision - Roadie 4 locks your strings in tune in under 10 seconds. Its upgraded vibration detection, redesigned audio circuitry, and high-torque motor deliver flawless accuracy even on stage or in loud rehearsal spaces. New Auto-Detect instantly recognizes and tunes any string you pluck.
* Works on Most String Instruments with Geared Pegs - electric guitars (6, 7, 8, or 12 strings), acoustic and classical guitars, ukuleles, mandolins, banjos, bouzoukis, lap steels, and more. Perfect for multi-instrumentalists who need consistent precision across setups. (For bass guitars, use Roadie Bass).
* Tune Your Way, Full Customization and 150+ Tunings - Explore built-in tunings like Drop D, Open G, DADGAD, Half Step Down, and more, or create your own. Adjust the reference pitch, tune with a capo on, or finish every string with Tune Up for rock-solid stability. Switch between Fast and High Accuracy modes to match your session needs.
* Built to Endure, Designed to Flow - A larger full-color screen, tactile scroll wheel, and ergonomic non-slip body provide effortless control even mid-set. The long-life USB-C rechargeable battery lasts for months on a single charge. With built-in Bluetooth 5.0 connectivity, Roadie 4 pairs with the free Roadie Tuner app for updates, tuning backups, and deeper customization, ensuring your tuner evolves with your sound.
* Integrated Winder and Advanced Metronome - Restring quickly and with full control using the 3-speed motorized winder, or use quick winding directly from the tuner screen to tighten or loosen your strings without leaving the tuning view. Keep time with the upgraded metronome that now supports full tempo, time signature, and rhythm customization, with both beep and vibration modes for any environment.
