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.

Custom Designed Alder Body

Unique angular shaped body contoured with no flat surfaces for extreme comfort and a balanced feel

Roasted Figured Maple Neck

Flame-figured roasted maple neck with ebony fretboard, including white dot position markers and exclusive matching, sculpted headstock

Black or Chrome Hardware

Black or chrome hardware, including black or chrome pickup covers, tremolo, control knobs, and tuning machines.

Infinity Radius Neck

Thoughtfully designed radius that enhances the visibility of the fretboard and uniquely positioned fret markers from any playing position

Multi-Scale Neck

24.75” to 25.5” (E to B or 1st to 7th string) multi-scale design provides affirmative string tension for thick and chunky rhythms on the bass strings, with a traditional feel on the treble strings for smooth bends and solos.

Steinberger Gearless Locking Tuners

Contemporary low profile and accurate, lightweight tuning machines feature smooth rotation and allow for a straight string pull.

New Music Man Pickups

Music Man designed custom HT (Heat Treated) humbucker in the bridge position features powerful lows with remarkable definition, resulting in one of the hottest pickups on the market. A slanted mini-humbucker in the neck position has been specifically designed to compliment the Kaizen bridge humbucker, offering an array of dynamic tones with outstanding sonic clarity. Overall, the Kaizen pickups give ultra-high-output, powerful low-end response while retaining a distinctively clean, clear tone and definition at lower volume levels.

Multi-Scale Tremolo

Super smooth modern Music Man tremolo with spring dampeners to alleviate unwanted overtones and ringing.
