Some guitars excel at one thing. The Just Right seems to excel at almost everything.

Its OM body shape has long been regarded as the sweet spot of the acoustic guitar world. Large enough to deliver impressive projection and bass response, yet comfortable enough for hours of playing, it strikes a balance that many musicians spend years searching for.

At the heart of the Just Right is a AAA Adirondack Spruce top. Revered for its power, headroom, and dynamic range, Adirondack responds beautifully to a light touch yet continues to open up as you dig in harder. Paired with Bolivian Rosewood back and sides, it produces a voice rich in sustain, depth, and harmonic complexity while maintaining excellent note separation and clarity.

The result is a guitar that feels equally at home accompanying vocals, exploring intricate fingerstyle arrangements, driving a bluegrass jam, or laying down tracks in the studio. It rewards nuance, welcomes aggression, and adapts effortlessly to changing musical styles.

If you own several guitars, the Just Right may become the one you reach for most often. If you own only one, it may be all the guitar you’ll ever need.

Description

The Riverboat Just Right combines the comfort and balance of an OM body with the power and dynamic range of a AAA Adirondack Spruce top and the rich sustain of Bolivian Rosewood back and sides. Equally suited to fingerstyle, strumming, flatpicking, recording, and performance, it is one of the most versatile guitars in the MacKenzie & Marr lineup.

 

FAQ

What is the difference between the Just Right and Tofino X

What is the difference between the Just Right and Tofino X?

Both guitars share the same philosophy: exceptional sound, comfortable playability, and direct-to-musician value. The difference lies primarily in tonewoods, and personality.

The Tofino X is an OM (Orchestra Model) built with a AAA Canadian Cedar top and African Mahogany back and sides. Cedar responds quickly to a light touch, making the Tofino X a favorite among fingerstyle players and anyone who values warmth, nuance, and a mature, played-in sound from the very first note.

The Just Right is also an OM, but it is part of the Riverboat Series and features a AAA Adirondack Spruce top paired with Bolivian Rosewood back and sides. Adirondack offers greater headroom and dynamic range, while Rosewood adds depth, richness, and long sustain. The result is a guitar with more power, stronger projection, and a broader tonal palette for players who dig in harder or want maximum versatility.

If your playing style leans toward fingerpicking, light strumming, and a warm, responsive voice, the Tofino X is an excellent choice. If you’re looking for greater projection, more headroom, longer sustain, and the complex overtones associated with premium Rosewood guitars, the Just Right may be the better fit.

Many players describe the Tofino X as instantly comfortable and inviting, while the Just Right delivers a larger, more authoritative voice that continues to reveal new tonal colours the harder you push it.

Who is the Just Right designed for?

Who is the Just Right designed for?

The Just Right was designed for players who want one guitar that does almost everything exceptionally well. Its OM body size strikes a balance between the power of a dreadnought and the comfort of a smaller-bodied guitar, making it equally at home on the couch, in the studio, at a jam session, or on stage.

Fingerstyle players appreciate its clarity, balance, and responsiveness, while flatpickers and strummers benefit from the headroom and projection provided by its AAA Adirondack Spruce top. The Bolivian Rosewood back and sides add rich overtones, strong bass response, and long sustain, giving the Just Right a voice that remains articulate whether played gently or aggressively.

If you’re the type of guitarist who plays a little bit of everything—fingerstyle one day, strumming with friends the next—the Just Right may be the most versatile guitar in the MacKenzie & Marr lineup.

How does the Just Right compare to a Dreadnought?

How does the Just Right compare to a dreadnought?

A dreadnought is designed to maximize volume, bass response, and power. The Just Right takes a different approach. Its OM body delivers much of the projection and headroom players want while offering greater comfort, balance, and versatility.

Compared to a dreadnought, the Just Right is easier to hold during long playing sessions, especially for players who spend hours practicing, recording, or performing. Its smaller body sits comfortably whether you’re seated or standing, while its narrower waist makes it easier to wrap your arm around.

Tonally, the Just Right sacrifices a little of the dreadnought’s low-end emphasis in exchange for improved balance across all six strings. Notes remain clear and distinct, making the guitar particularly well suited to fingerstyle playing, recording, and accompaniment vocals. At the same time, its AAA Adirondack Spruce top provides enough headroom and projection to satisfy players who enjoy energetic strumming and flatpicking.

Many players find that a great dreadnought excels at certain styles, while a great OM excels at almost everything. That’s why the Just Right has become a favorite among guitarists looking for a single instrument capable of handling a wide variety of musical situations.

Why is it called the Just Right?

Why is it called the Just Right?

The OM body shape has long been considered the “Goldilocks” size of the acoustic guitar world. It’s larger and more powerful than a parlor or 00, yet smaller and more comfortable than a dreadnought. For many players, it’s simply… just right.

That balance extends beyond the guitar’s size. The Just Right combines the power and headroom of a AAA Adirondack Spruce top with the richness and sustain of Bolivian Rosewood. It delivers enough projection for energetic strumming, enough clarity for fingerstyle playing, and enough comfort for hours of practice or performance.

Some guitars are specialists. The Just Right is a generalist in the best possible sense. If you could own only one acoustic guitar and wanted it to excel in the widest range of musical situations, the Just Right would be difficult to beat.

That’s why we named it the Just Right.

Is the Just Right comfortable to play for long sessions?

Is the Just Right comfortable to play for long sessions?

Yes. In fact, comfort is one of the reasons so many players gravitate toward the OM body shape.

The Just Right is large enough to deliver impressive projection and bass response, yet compact enough to sit comfortably against your body for hours at a time. Its narrower waist makes it easier to wrap your arm around than a dreadnought, reducing shoulder and arm fatigue during long practice sessions, performances, or evenings spent playing on the couch.

Many players find that larger guitars can feel cumbersome after an hour or two. The Just Right was designed to avoid that compromise. It offers much of the power and presence associated with larger instruments while remaining comfortable and balanced whether you’re seated or standing.

For players who value both sound and ergonomics, the Just Right truly lives up to its name.

What type of music is the Just Right best suited for?

What type of music is the Just Right best suited for?

The Just Right is one of the most versatile guitars in the MacKenzie & Marr lineup. It excels at folk, singer-songwriter, acoustic rock, country, Celtic, blues, and contemporary fingerstyle music, but its real strength is its ability to adapt to almost any playing style.

Its AAA Adirondack Spruce top provides the headroom and projection needed for energetic strumming and flatpicking, while its Bolivian Rosewood back and sides deliver the sustain, depth, and harmonic richness that fingerstyle players appreciate. The balanced OM body shape ensures that individual notes remain clear and articulate, making the guitar equally comfortable accompanying vocals, recording in the studio, or performing live.

If your musical interests span multiple genres and you want a guitar that can keep up with all of them, the Just Right was designed with exactly that player in mind. Rather than specializing in one particular style, it strives to do everything remarkably well.

Which MacKenzie & Marr guitar would you choose if you could only own one?

That’s a difficult question because the answer changes from time to time—even for us.

When heading out on a road trip, the Baby Boat is often the first guitar into the car. Its compact 00 body is comfortable to travel with, yet it delivers a surprisingly full voice that never feels like a compromise.

At home, the choice frequently comes down to the Just Right and the Grand Manan Too. The Just Right offers the headroom, sustain, and complexity of its Adirondack Spruce and Bolivian Rosewood combination, while the Grand Manan Too delivers a wonderfully balanced Grand Auditorium voice that seems to suit almost any musical mood.

Ask again next month and the answer might be different. That’s the beauty of acoustic guitars. Each has its own personality, and different guitars inspire different music on different days.

If we absolutely had to choose just one, the Just Right would probably get the nod. Its OM body, Adirondack Spruce top, and Bolivian Rosewood back and sides make it one of the most versatile guitars we’ve ever offered. It handles fingerstyle, strumming, flatpicking, recording, and performance with equal confidence, making it a strong candidate for the “one guitar” role.

The MacKenzie & Marr Riverboat ‘Just Right’ is an absolute powerhouse. It is friendly when you want it to be, but a force when you dig in. Honestly, it is unlike any acoustic I have ever played—and I have been through quite a few lately.

🎸 Flawless Setup and Extra Space
Right out of the case, the action and intonation are spot-on. Moving around the neck is completely effortless. For me, the real game-changer is the 1.75-inch nut width. After recovering from a tendon injury in my fretting hand, I needed a bit more breathing room on the fretboard. This wider spacing gave me exactly what I needed to play comfortably again.

🎼 Handles Every Style Imaginable
I play guitar completely bare-fingered with no thumb pick. Because I also play mandolin, uke, and bass, my style jumps all over the place. This guitar doesn't blink. It handles every single thing I throw at it, including:
• Folk, country, swing, and old jazz standards
• Fiddle tunes and bluegrass
• Complex (yet simple) jazz shell chords
• Contemporary and some old rock 'n' roll

🔊 Exceptional Headroom and Note Separation
MacKenzie & Marr’s description is right on the money. I used to play their Tofino model, which is great for fingerstyle, but the Riverboat has a massive amount of headroom. You do have to adjust your attack, though. A super light touch yields a gorgeous tone, but if you dig in too hard, it gets loud enough to bury your vocals. The low end is deep without ever getting muddy or boomy. Best of all, the note separation is incredibly clean, which is crucial when you have four fingers picking at the same time.

🏆 Can't Put It Down
If you are looking for an inspiring, versatile acoustic that can do it all, this is it. I can't seem to leave this guitar on its stand for more than a few minutes.

💭 The One Regret
My one regret is that my local luthier, who could have provided a wonderful custom instrument to my specifications, did not get my business.

This gorgeous OM-size guitar is never leaving my family. After 3 days I already have it willed to my son. It’s made out of tone woods to die for: The top is AAA Adirondack Spruce like all the pre-war Martins that ring out like the bells of Notre Dame. The body and sides are Bolivian Rosewood, which easily lives up to the old Brazilian legends, and perhaps even a little more. The grain is insane, with colors that are exciting, and the natural spline up the book-matched back is a modernistic free-form tying it all together. The craftsmanship on the gluing, forward scalloped braces, and structural perfection have an old-world purity that for some reason reminded me of a Stradivari Messiah violin; even though made by humans, it’s slightly otherworldly. The real quill – the sound – is as promised, with the reverb, sustain and tonal nuances that keep the last single note resounding for 6 seconds, and the harmonic overlay of the strings in play have that orchestral quality that you get from $4,000 to $6,000 big name guitar-makers. It’s slightly heavy requiring a strap if you’re performing or standing, and it’s built like a German submarine; if you take it on tour, you’ll break the tour and not the guiar. The flame maple binding everywhere gives it that all good wood magic, and the green abalone purfling is elegant without being obvious guitar bling. Is it the “Best guitar in the world?” I think it will be close when this beautiful box plays in and loosens up. Right now it’s certainly among the finest I’ve ever strummed or picked. If the devil is in the details, this is one Hell of an instrument!

I spent several days deciding which model I wanted. I decided on the River Boat Just Right. I waited a month between the order and the arrival. During that time I spent a lot of time looking at pictures and reading descriptions. When it finally arrived I was absolutely stunned. The materials, the finish, the fit, everything was as described. The sound is strong, balanced and full either with or without the pickup. I would compare this favorably with guitars costing 3 - 4 times as much.

Let me be clear about something from the start… I’m basically a cheapskate. As favorable as the
prices of Mackenzie and Marr guitars are, I’ll STILL squeeze a nickel until the buffalo defecates all
over my hand! So when I look for guitars, or most anything else, I instinctively look first to the used
market before making a buying decision.

With MacMarrs, that’s a problem for me… the folks who buy a Mackenzie and Marr guitar are very
unlikely to sell it. They’re VERY scarce on the online sites like Reverb… and that fact says something
very GOOD about the guitars. Those in the know who buy a MacMarr tend to think of them as a guitar
that they’re gonna have for a LONG time.

In any case… I was surprised and intrigued when MacMarr introduced the Riverboat Just Right. It seemed
like a good idea, and I wanted to try one out.

I was surprised when a Just Right showed up in the used guitar listings on Reverb. A new model showing
up on the used market so soon was a shock to me… the signs pointed to it being part of an estate sale,
done by relatives who wouldn’t know a fine guitar from a railroad tie with strings and tuning machines
attached to it.

A bit of haggling with the seller and I got what I consider to be a super deal. UPS did the rest.

What arrived yesterday was astonishing. It looks like this guitar just came from the loft in Montreal; little
or no use, and the foam shipping pads still in the case. Pick guard there, and truss rod wrench and case keys
had never been out of their envelope. The guitar itself is pristine, and unsurprisingly the fit and finish are
up the very high standards that I’ve come to expect from Mackenzie and Marr instruments.

Getting out my Riverboat Dread and my beloved Baby Boat, I did a shootout comparison to see just where
the Just Right fits into the scheme of things.

I’m a big guy (6’ 0” and 260 pounds), and the Dreadnaught works well for me. The Baby Boat is petite, and it
feels a bit like a toy in my oversize Biker’s hands; it’s the only guitar I own that I feel the mandatory need to play
with a strap.

The body of the Just Right immediately nestled quite comfortably on my knee; it fills a niche that the other two
couldn’t match. It’s immediately obvious just WHY they named the model the Just Right; on my scoreboard it
racked up an immediate two points!

The guitar was shipped from a humid southern coast state, and I imagine it will take a while for it to acclimatize
to the very different and cooler conditions of Southern Wisconsin.

As for the sound…

The Dread has a big, booming voice with a whole lot of bottom end; it’s a real gut bucket. Adequate top end, and
nicely balanced.

The Baby Boat is also nicely balanced, but it’s a little short on the bass end for my tastes. With it’s small body that’s
not a surprise.

It’s a simple case of Different Horses for Different Courses… a parlor guitar isn’t reasonably expected to fill an auditorium
with sound like a Dreadnaught is. The Baby Boat is best as a solo instrument in small, quiet venues, and the Dread is
designed for making coleslaw out of the fiddle in a Bluegrass band on numbers like Black Mountain Rag or Jerusalem
Ridge.

The Just Right strikes a nice balance with its big brother and little sister. It seems to be a Do Everything Well instrument;
it can work well as a solo performance box, and it can hold its own in a dogfight with fiddles and mandolins at a hoedown.

Congratulations Mackenzie and Marr… You hit it out of the park. Again!

I have to agree with Goldilocks when she says the "Riverboat Just Right is 'just right'."
It looks good, it's well put together, the intonation is impressive, and it has a very pleasant tone. I'm quite happy with the guitar.
Initially there was a fair bit of fret buzz above the 8th fret, the saddle required a small shim to improve contact with the pickup, and the neck required a minor truss rod adjustment to take out un-necessary relief. These issues have all been addressed and as I said above, I am quite happy with the guitar.
I will be leaving it on a stand for awhile to facilitate off gassing of the finish-a new issue for me as every guitar I ever bought was old!
Do you have recommendations for strings?
If you have potential buyers in my corner of the world, I would be happy to let them view the instrument.
