Compatibility
Fits More Pegs. Tunes More Instruments.
Now redesigned with a versatile peg connector, it fits both smaller and larger tuning pegs with ease. The rubberized texture ensures a secure grip, delivering smooth, quiet tuning—no slipping, no shaking, just steady precision across a wide range of instruments.

How It Works
A built-in contact microphone and advanced audio processing detect string vibrations, analyze pitch, and automatically rotate the tuning peg with remarkable precision. No need to focus—just hold it in place and let it handle perfect tuning every time.

Tune Your Instrument in 3 Simple Steps:

Auto-Detect
By default, it tunes from the lowest to the highest string. But with the new auto-detect feature, you can pluck any string in any order, and it will instantly recognize and tune it. A gentle beep and vibration let you know when the string is perfectly in tune.

What's New

Restring, Tune, and Track — All in One
Equipped with a built-in winder featuring three speed settings, it gives you full control over the restringing process. Whether you want a quick wind or a slow, precise turn, this tool makes changing strings faster, smoother, and easier than ever.

Play in Perfect Time — With Beep or Vibration
The built-in metronome gives you complete control over tempo, time signature, and rhythm. Set your BPM, choose your beat count, and add subdivisions like eighth notes or triplets to suit your style. Switch to vibration mode to feel the beat — ideal for quiet practice or noisy environments.

Customization
Tune Your Way. Every Detail, Your Control.
With advanced features and fully customizable settings, you can fine-tune speed, precision, and setups to match your instrument and style — exactly how you like it.

Set to “Tune Up”
The optional Tune Up mode finishes each tuning by tightening the peg for extra stability. Many players prefer this method for longer-lasting accuracy — but you’re free to choose what works best for you.

Create Custom Tunings
From tempered scales to alternate tunings, customize each string down to the cent to suit your setup or ear. Perfect for guitars with custom nuts, bridges, or floating systems like Floyd Rose—just follow the recommended string order to keep tension balanced. Save your tuning once and recall it anytime with a tap.

Tune with a Capo
Using a capo? No problem. Just tell Roadie which fret it's on, keep the capo on, and your preset tunings will adjust automatically so Roadie tunes for the key you're playing in.

Adjust Your Reference Pitch
Not limited to A=440 Hz? Set your reference pitch anywhere from 420 Hz to 460 Hz in 1 Hz steps—ideal for historical tunings, orchestral settings, or syncing with fixed-pitch instruments.
