A visionary collaboration designed for the modern 7-string player.

The Ernie Ball Music Man Kaizen 7-string electric guitar is a bold new creation born from the collaboration between Ernie Ball Music Man and renowned guitarist Tosin Abasi. Built to push the boundaries of what a modern 7-string guitar can do, the Kaizen is crafted with forward-thinking design elements that enhance both playability and performance. The contoured alder body, roasted figured maple neck, and multi-scale ebony fretboard with an “infinity radius” offer a sleek, ergonomic playing experience that matches Tosin Abasi’s innovative approach to guitar design.

Music Man HT Pickups for Dynamic, 7-String Power

The Kaizen 7-string features a Music Man HT bridge humbucker and a custom offset neck humbucker, delivering the dynamic range and clarity needed for modern progressive music. The 3-way switch with a custom middle position allows for versatile tonal options, from searing high-gain leads to clean, articulate lows. Whether you’re playing complex rhythms or intricate solos, this guitar provides the tonal flexibility to meet the demands of any musical style.

Multi-Scale "Infinity Radius" Fretboard for Enhanced Playability

The multi-scale length fretboard on the Kaizen 7-string is designed with Tosin Abasi’s signature “infinity radius,” providing improved visibility and ergonomic comfort during performance. The roasted figured maple neck and ebony fretboard deliver a fast, smooth playing surface, while the contoured body ensures long-lasting comfort. With 24 medium jumbo frets, this guitar offers the perfect balance between technical precision and expressive playability.

Built for Players Who Demand Innovation and Precision

The Kaizen 7-string is designed for guitarists who need precision, versatility, and cutting-edge design. The Music Man tremolo system provides smooth, reliable tremolo action, while the Steinberger gearless tuners ensure rock-solid tuning stability. From technical progressive playing to heavy low-end chugging, this guitar is built to keep up with the modern player’s demands. Each Kaizen comes with a G&G hardshell case for ultimate protection.
