Ernie Ball Music Man Kaizen
www.music-man.com
Ernie Ball Music Man’s instruments have a way of attracting virtuosos. Annie Clark, John Petrucci, Steve Morse, and even Eddie Van Halen lent their names to models that became instrumental in their creative process, and big parts of their musical and visual identity, too. Over the course of the pandemic, fellow virtuoso Tosin Abasi had time to try a few EBMM guitars, including a Goldie (St. Vincent signature model) and Valentine (James Valentine signature model). He came away impressed.
While Abasi has his own line of boutique guitars called Abasi Concepts, he knows resources from a big, established company can bring a lot of cool ideas to life. Abasi also likes the company’s bold embrace of unusual body shapes. Abasi and EBMM started talking, and, by NAMM 2022, Abasi and EBMM’s collaboration, the Kaizen, was real. The Kaizen is a unique 7-string with a load of evolutionary player-oriented features and a high but justifiable price tag. A 6-string version is in the works for those that prefer a more traditional instrument. But little about the Kaizen, in any form, feels traditional.
Forward-Thinking Features
The Kaizen’s very 21st century profile is a progressive move in design terms. This ain’t your uncle’s Tele. Our test model is finished in Apollo black, decked out in all black hardware, and looks quite like something out of The Matrix. As wild as it looks, the guitar’s body shape is just the first in a long list of modern elements.
The Kaizen’s roasted flame maple neck is a marvel. It has a multi-scale setup—25.65" on the high E string to 25.5" on the low B string. On the bottom side, the longer scale length gives you a tighter feel and better tuning stability (even if you drop the low B further in pitch), and on the top end, the shorter scale length gives you a slinky feel for shredding and bending. The Kaizen’s ebony fretboard is fitted with 24 medium-jumbo stainless-steel frets in a fanned configuration.
Eschewing conventional tuners, the Kaizen features Steinberger gearless locking tuners (similar to those on the discontinued Steinberger GS) with a 40:1 ratio that facilitate smooth, super-accurate tuning. Aesthetically, it’s very hip and the low profile of the tuners add to the guitar’s almost aerodynamic appearance.
Optimized for Speed
Ernie Ball Music Man makes some of the best production guitars around. And I’ve seen quality in EBMM instruments that rivals many custom builds. The Kaizen is no exception, and it arrived perfectly set up in its fitted G&G hardshell case.
“Contours are everywhere (even the back plate is shaped), and the guitar is almost entirely without flat surfaces.”
Tosin Abasi’s virtuosic style of music will challenge any guitarist, no matter how technically adept. Executing almost any of Abasi’s ideas puts playability at a premium, and the Kaizen is really built to feel like a natural, seamless extension of the player. The body is ultra-ergonomic. Contours are everywhere (even the back plate is shaped), and the guitar is almost entirely without flat surfaces. The neck’s thin profile and satin finish makes it feel extra fast, and the sculpted heel makes for unobstructed access all the way up to the 24th fret. The fretboard is slightly thicker on the treble side than the bass side, and its “infinity” radius enables you to see the entire fretboard with ease.
Kaizen’s vibrato system is excellent, too. The whammy bar is set from the factory to only go down in pitch. Using it vigorously, I was impressed that the guitar stayed perfectly in tune, even without a double-locking nut system. The guitar has a compensated nut, and the strings go straight through the tuners without a break angle, which improves tuning stability.
Modern Meaty Sounds
The Kaizen’s pickup configuration consists of a heat-treated Ernie Ball Music Man bridge pickup and a mini humbucker in the neck. While high gain is part of the mission, the pickups are also clear and present. And though they are passive, they sound awake and powerful, like active pickups do. The 3-way pickup selector switch offers bridge humbucker, bridge and the neck’s outer coil combined, and both coils from the mini humbucker in the neck.
In high-gain situations (I used a Mesa/Boogie Tremoverb combo, Mark IV head, Bogner Ecstasy Mini Red, and Line 6 M9 Stompbox Modeler as amp and pedal pairings), the bridge pickup offers abundant sustain. Notes blossom into feedback beautifully and djent-style rhythmic figures cut through with razor-sharp accuracy.
“This ain’t your uncle’s Tele.”
The combined pickup setting is excellent for clean, percussive, slap-and-pop figures, like those that R&B bass players use, as well as the thumping moves you hear from Abasi. In this setting, pick attack feels immediate, and the guitar really cuts, even at lower volumes. It’s also an ideal setup for funk-type rhythm figures. The middle pickup setting is articulate in dirty settings, too, and fast, alternate-picking licks pop like a machine gun.
The neck mini humbucker, meanwhile, is versatile and responsive. It delivers creamy classic blues sounds in dirty amp and pedal settings, especially when you roll guitar tone and volume back a touch. Open up the guitar’s tone and volume and the Kaizen is a heavy rock monster. As big and explosive and Kaizen can sound, in cleaner settings it’s very rich. The guitar’s pots also give you room to shape a great range of cleaner tones. With the tone knob almost all the way off, it still sounded clear through the mellowness, and there was almost none of the blanket-over-speaker, mushy tonality you hear from most guitars when the tone control is down. Pretty impressive.
The Verdict
The Kaizen is an exquisite instrument. There is little question about the music the guitar is intended for. It’s a shred machine, first and foremost, made for modern, heavy styles. But it’s easy to imagine how it would excel in other contexts because of the wide variety of sounds available. It would make a very interesting progressive jazz instrument for sure.
While the roughly $4k price tag will be a barrier for many, it’s not obscene for what you get. If you’re a forward-thinking guitarist, particularly one that feels like you’ve squeezed all the tricks you can from your old instrument, the Kaizen has the potential to unlock a lot of new ones.

AEROSMITH guitarist and songwriter JOE PERRY is set to return to the road for a series of August performances with THE JOE PERRY PROJECT. The 8-date run kicks off August 13 in Tampa, FL and wraps August 23 in Port Chester, New York, with an August 19 performance in PERRY’s Boston hometown (see the itinerary below). For the North American trek—which marks the first solo shows for PERRY this year—the legendary guitarist will be joined by his Aerosmith bandmates Brad Whitford (guitar) and Buck Johnson (keys), along with The Black Crowes’ Chris Robinson (vocals), and Stone Temple Pilots’ Robert DeLeo (bass), and Eric Kretz (drums).
“Well…it’s time to let the music do the talkin again,” PERRY says. “I’m really excited about the JPP line up this year!!!! Most of these guys played with me at The Roxy in L.A. at the debut event for my latest solo album [Sweetzerland Manifesto] in January 2018. They’re all busy as hell but thankfully they’re able to carve out some time for this run. And I’m not only lucky enough to have Brad Whitford onstage with me but Chris Robinson of The Black Crowes! [who sang ‘Fortunate One’ on Sweetzerland Manifesto MKII], Robert DeLeo and Eric Kretz from STP!!! and Buck Johnson who plays keys and sings with Aerosmith, the Hollywood Vampires, and is also a solo artist in his own right.”
For the shows, the Rock and Roll Hall of Fame inductee says “the set list is gonna include my fav JPP cuts, STP, Black Crowes, and with Brad we’ll be hitting the Aero hits and some deep cuts and then ya never know!!!! Gonna be a BLAST, and if you’ve ever been to one of my shows you know the words GARAGE BAND on STEROIDS come to mind! See you there!!!!”

Seasonal changes are tough on your acoustic. Here’s how you can take better care of your prized instrument.
As you read this, spring is in bloom in most of the US, or maybe it has been for some time. I’m timing this column specifically to ask acoustic guitarists, in this season of increasing humidity and comfortable conditions, to prepare for what’s coming. It’s never too soon, and time flies. Before you know it, we’ll be back to the maintenance phase and you might be blowing up the phones of your local guitar shops, luthiers, and techs. I’m here to encourage a decidedly old-school approach to preventative guitar maintenance, and yes, it starts now.
Why, you ask? Well, as the lead luthier at Acoustic Music Works, I can tell you that in my nearly 15 years in this position, this was the worst winter ever for preventable repairs on acoustic guitars. Fret sprout, bridge lifts, top sink, soundboard cracks, back cracks, loose binding, general malaise… These hit us very hard in the winter that spanned 2024 and 2025. Am I complaining? On the one hand, no. This is part of how we make our money. On the other hand, yes! Repair schedules related to dryness and humidity issues can stretch into weeks and even months, and nobody wants to be without their favorite instruments for that amount of time. With a little thoughtfulness, however, you might get through next winter (and every one thereafter) without hefty repair bills or time apart from your musical companion.
Our preparation is going to start with an unlikely but very important guitar accessory: the humble notebook. Plain, lined, grid, day planner… it doesn’t matter. We all need to actively participate in our instrument maintenance, and in my experience, fancy apps that track humidity via Bluetooth breed a kind of laziness, a feeling of safety that might prevent us from actually physically looking in on conditions. Better we keep an analog, well, log, so that we know where things stand, and I suggest checking in daily.
“This was the worst winter ever for preventable repairs on acoustic guitars.”
Track your relative humidity, both in the case and in the room where your instruments mostly reside, but also take notes on your action height, top deflection (StewMac has some great tips for measuring this) and anything related to playability that you believe you can observe empirically.
Dryness is the root cause of most guitar issues that manifest in the fall and winter months. Symptoms of dryness include sharp fret ends, falling action and dead frets, sunken top around the sound hole, and cracks and bridge lifts. With your trusty notebook, you’ll get a feel for the sensitivity level of your instrument, and that knowledge is power!
A few other basic implements will not only assist you in your observations, but may also satisfy your need to buy guitar-related things (at least for a minute). Getting quick and comfortable with a fret rocker is a great skill to have, and is invaluable in diagnosing buzzes due to high frets or frets that have come unseated due to dryness. A well-calibrated relief gauge might seem luxurious, but it can prevent you from making unnecessary or extreme truss rod adjustments. A string action gauge, or even a simple machinist’s rule or set of feeler gauges, will help you keep track of your action. Get a three-pack of hygrometers so you can average their readings, rather than depending on one.
Lest we forget: A guitar can not only be too dry, it can also be too wet. By beginning your maintenance diligence in the spring/summer, you’ll also be able to tell if your instrument is the victim of a too-humid environment. The signs of over-humidification are subtle: Your action may rise from a puffed-up top, and in extreme cases, glue joints could begin to fail. In my experience, an over-humidified guitar will suffer from dulled tone, almost like a sock in the sound hole. If you’re sensing a lack of clarity in your guitar all of a sudden, start with new strings. If it persists, it might be due to over-humidification, and you may want to introduce a desiccant to the case for a time. The more lightly built your guitar is, the more sensitive it will be to seasonal changes.
By getting into these habits early, you’ll be empowered by knowing your instrument more intimately. You’ll understand when and why changes in tone and playability might have occurred, and you’ll hopefully save on repair bills year-round. Feel free to reach out with any questions. Who knows? I might just send you a notebook with an AMW sticker on the cover!
