The Ernie Ball Music Man Kaizen 7-string electric guitar is a truly revolutionary design that serves both iconoclasts and everyday players. It’s no small wonder the Kaizen—which is a Japanese word for "continuous improvement"—is a collaboration between the Ernie Ball Music Man design team and the celebrated progressive guitarist, technician, innovator and inventor, Tosin Abasi.

"Some people look at the guitar as fixed," says Abasi, "but I’m inspired by pushing the design further. This is a new thing in the guitar space—which is exciting—but I also wanted to add to the tools available to guitar players, providing one more option that maybe didn’t exist before."

The Kaizen includes a "decidedly contoured" body with no flat surfaces, a multiscale fretboard with an "Infinity radius" that improves visibility while playing, a custom tremolo usually not offered on multiscale guitars, a custom-wound Music Man HT bridge humbucker and Steinberger Gearless locking tuners.
