How is Roadie 4 different from Roadie 3?

Roadie 4 tunes faster and more accurately with upgraded tuning tech. It also has a bigger 1.9″ color screen, better grip, a wider-fit peg connector, and a scroll wheel for easier control.

How does Roadie 4 detect which string you’re tuning?

Roadie 4’s new Auto Detect recognizes which string you play, tuning it instantly. By default, if Auto Detect isn’t enabled, it tunes strings sequentially from the top.

What alternate tunings are available on Roadie 4?

Roadie 4 includes 150+ built-in alternate tunings for 12 instrument types, including Drop D, Drop C, Open C, Open D, Open G, and DADGAD. You can also create and save your own custom tunings using the Roadie Tuner app.

Can Roadie 4 help with winding guitar strings?

Yes. Roadie 4 includes a built-in string winding feature that quickly winds or unwinds strings during restringing. After winding, it can immediately tune the new string, making the entire restringing and tuning process faster and more convenient.

How do I enable the “Tune Up” feature on Roadie 4?

Open Settings on Roadie 4 or in the Roadie Tuner app, enable the “Tune Up” option, then press Sync to apply it. When enabled, Roadie slightly detunes each string below pitch before tightening to the correct note for more stable and reliable tuning.

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.
