Manufacturer's Description

Ernie Ball Music Man proudly presents the Kaizen guitar, a visionary collaboration between the Ernie Ball Music Man design team and the world-renowned guitarist, innovator, and designer Tosin Abasi. The Kaizen is a cutting-edge design concept that was inspired by Tosin's distinct playing style and vision. Featuring Music Man’s proprietary "Infinity Radius Fretboard" and uniquely positioned fret markers, the feel and playability of the Kaizen is enhanced with improved visibility of the fretboard in any position. The instrument is light and undemanding, with a distinctly shaped alder body, a slim profile roasted maple neck, and a multi-scale length fretboard. The electronics include a new Music Man HT bridge humbucker, a custom offset neck humbucker, and a 3-way switch wired with a custom middle position. Each guitar comes equipped with a Music Man multi-scale tremolo, Steinberger gearless tuners, and a Mono soft or G&G hardshell case.

  • Fretboard Profile: The fretboard is thicker on the treble side and that is the peak of the fretboard radius. It folds towards the player on the low B side. This creates better visibility of the fretboard for the player. While the roasted maple aspect of the neck is symmetric, the assymetric fretboard does create an asymmetric feel to the neck.
