Ernie Ball – ProTune USB-C Rechargeable Clip-On Tuner

Precision Tuning, Reimagined

The Ernie Ball ProTune combines road-ready durability with modern charging convenience. Engineered for musicians who demand absolute accuracy, the ProTune offers a lightning-fast response and a tuning accuracy of ±0.1 cents. Whether you’re on a dark stage or in a sunlit studio, the high-definition color screen ensures you can see your pitch clearly from any angle.

USB-C Rechargeable Power

Integrated with a long-lasting lithium-ion battery, the ProTune provides up to 10 hours of continuous tuning on a single charge. When you’re running low, simply plug it into any standard USB-C cable (included) to top it up. An intelligent Auto-Off feature saves your battery by powering down after a period of inactivity, ensuring it’s ready when you are.

Versatile & Rugged

The ProTune isn’t just for electric guitars. With five dedicated tuning modes – Chromatic, Guitar, Bass, Violin, and Ukulele – it is a truly universal tool. The heavy-duty, spring-loaded clamp is designed to grip securely to almost any headstock without damaging the finish, while the 360-degree swivel arm lets you find the perfect viewing angle every time.

GuitarBuddy Tip

The Ernie Ball ProTune is our top recommendation for the gigging musician. Since most modern pedals and phones now use USB-C, you can finally clear those old button batteries out of your gig bag and use the same charging cable for your tuner!
