A Groundbreaking Collaboration with Tosin Abasi

A new design, the Kaizen 7 is not a signature guitar — it’s a collaborative design between Tosin Abasi and Music Man. Shaped from alder, the original body design is contoured all the way around, leaving no flat surfaces on the instrument. The body is loaded with two all-new pickups — a slanted mini-humbucker in the neck and a full-size Custom HT heat-treated humbucker in the bridge — that deliver huge, tight tones. The roasted maple neck features a multi-scale ebony fingerboard with a 24.75–25.65-inch scale length. Music Man and Tosin also developed an innovative Infinite Radius fingerboard profile that allows you to see every inch of the fretboard while playing. Players at Sweetwater also appreciate the tremolo tailpiece — a rare sight on a multi-scale 7-string guitar. If you’re ready to experience something totally new, you’ll want to add the Kaizen 7 to your stable of guitars.

Exclusive humbucking pickup configuration

Ernie Ball Music Man developed two brand-new pickups for the Kaizen 7. The slanted neck pickup is a mini-humbucker mounted directly into the contoured alder body. With its naturally narrow field, the mini-humbucker gives you all the focused midrange bite you love with extra high-end clarity. Meanwhile, Tosin specified a custom-wound HT humbucker for the bridge position. Bolstered by a proprietary heat treatment, the HT humbucker showcases greater output, a huge dynamic range, and boosted presence. The Kaizen 7 has a 3-way pickup selector switch and Master Volume and Tone controls for shaping your sound.

All-new Infinity Radius fingerboard

Kaizen 7 is outfitted with Music Man’s Infinity Radius fingerboard design. Infinity Radius is an all-new concept with a slightly conical profile. The ebony fretboard is slightly thicker on the treble side with the cone’s pinnacle at the high E string. The Infinity Radius design lets you see the whole fretboard and fret markers from your playing position. Paired with the slick roasted maple neck, the Infinity Radius fingerboard is comfortable and sure to impress.

Multi-scale stainless steel frets and other thoughtful appointments

Tosin and Music Man spared no detail when designing the Kaizen 7. The guitar has an ebony fingerboard, 24 multi-scale stainless steel frets, and a 24.75–25.65-inch scale length. Multi-scale frets offer better intonation, keep the low strings at a higher tension, and allow the higher strings to bend with ease. The Kaizen 7 also has Steinberger gearless locking tuners that keep the strings arrow-straight from the tuning machine to the bridge. This design choice ensures you enjoy outrageous tuning stability under all playing conditions. Speaking of the bridge, Kaizen 7 has a custom-designed multi-scale tremolo bridge and tailpiece for even more expressive playing.

Why Buy Your Guitar from Sweetwater?

See how Sweetwater goes to great lengths to give you the very best online guitar buying experience.

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Best 7 string.
Pricey but it's totally worth it. Super versatile, comfortable, and easy to play. Only 3 pickup modes but they cover a lot of ground and get a good variety of tones. Super high level build quality.
The Kaizen 7 — a very versatile guitar
Let me start by saying I don't leave feedback often. I've been working with Tom Maxwell at Sweetwater for well over a decade. He has always been a great source to find the right equipment. In this case, I purchased my first 7 string guitar. The Kaizen 7 might be my favorite guitar to date. From the looks to the tones, this guitar rocks!!!!
Idk

Wrote a review on the black one I bought from sweetwater but can't find it. Idk if this instrument is worth the high price tag anymore. Probably gonna be my one and only music man instrument. Things have come out about this model that makes me a little disappointed tbh. Bridge posts

Cracking the surrounding wood, improper nut causing intonation issues, and the manufacturer gaslighting people into thinking it's rare. It may be but with a 1 yr warranty and the price of these they should be bulletproof. I've had trouble with mine getting a low enough action without significant buzzing. My questions to Ernie ball about it were politely dismissed.Should we also have these guitars pleked at our expense as well? Maybe I'll give esp a try….
