Building a small body guitar is easy. Building one worth listening to? Not so easy. And one that is a joy to play? Even tougher.

It took us two years of experimentation and samples before we finally created a 00 size solid wood acoustic we could call an authentic MacKenzie & Marr guitar. Calling upon two highly respected luthiers, we started by re-engineering the bracing. Highly sculpted X bracing supports the top without restricting the "acoustic trampoline" of the quarter sawn Sitka Spruce. The back and sides are solid African  Mahogany (Khaya Ivorensis), which suits the geometry of a small body guitar perfectly. By engineering the neck of Opeongo to transmit acoustic vibrations along its length, telegraphing them to the slotted headstock, we've expanded the resonating chamber beyond the physical confines of the body.

The overtones and sustain created by the play of space and materials belie the small body size. Hearing the true"wood" voice of Opeongo and experiencing the projection of that voice for the first time throws everyone off. Playing Opeongo is even more of a joy. Twelve frets to the body (most guitars including our other models have 14 frets clear of the body) mean less stretching and more comfortable fingering. Even barre chords become pleasurable to play (pleasurable, in this case, being highly subjective because who among us enjoys barre chords?). The 1 3/4 inch fretboard width at the nut encourages accurate fingerpicking.

As with all MacKenzie & Marr Guitars, Opeongo comes with a limited lifetime warranty against any manufacturing and/or material defects. Play this guitar in the comfort of your own home for a week. If you don't fall in love with it, we'll take it back and issue a full refund, including shipping costs.

A hard shell case is included at no additional cost with every Opeongo guitar.

My new little Opeongo guitar is definitely a keeper! I’ve been playing it pretty much nonstop since I got it. The combination of mahogany back and sides and spruce top is amazing and just what I’ve been looking for. The combination of these tone-woods and the deeper sound box really adds up to a clear, full, and robust sound. The shape of the neck is super comfortable. And while the Opeongo doesn’t sound quite as good with a capo as my Martin 00 ms15, and doesn’t ring as clear beyond the 12th fret, this is a fine instrument and is a welcome addition to my collection. This is a great looking little guitar, too. The logo on the headstock is handsome, and it also looks great on the awesome hard shell case the guitar comes in. There were some minor issues upon delivery, but John Marr kindly and promptly replied to my email and we worked that out. He even checked back with me a few days later to make sure everything was okay. Thanks John:) I’m quite happy with this M&M guitar, and I seem to pick it up these days instead of any of my other guitars. With the “fall in love in a week” guarantee, there’s really nothing to lose. That guarantee speaks confidence! Take MacKenzie and Marr up on that—you won’t be sorry.

I purchased a guitar from Mackenzie Marr a year and a half ago, but sadly had to return it. The dimensions of the guitar did not suit my playing style. I returned it, with no hassel. This time around I did a little more homework and ordered a small palour guitar, the Opeongo OO. The guitar is exactly to spec and arrived well packaged and in a beautiful hard shell case. I love the look and feel of this guitar. A lot of sound from a small package. The neck is a little wider than what I am used to. It kinda' reminds me of an old Norman I learned to play on. The 12 fret neck is a unique experience and does make playing bar chords a little bit easier as your position over the guitar changes. I have noticed that the tuning keys become quite loose when the string tension lessons. However, they are Grover tuners and there should be a simple answer to that one. The open head stock does seem to transmit some sound as well, which was new learning for me. I like that the pick guard is optional, as I am not a hard strummer and the appearance of the guitar is a lot more authentic without it. I have owned Taylors, Martins and Guilds...some have worked well, others have moved on. But, I will be keeping this Mackenzie Marr parlour guitar. Thanks for your interest.

Bonjour à tous, je vais débuter en vous disant que depuis plusieurs mois pendant ma recherche de guitares qui se démarquent, je voyais sans arrêt des publicités sur Mackenzie and Marr. Je me demandais quelle était cette marque exactement. J'ai donc pris le temps d'aller voir les guitares, les reviews et des vidéos. Plusieurs fois, je suis allé sur le site, placé les guitares au panier en me disant...ah je devrais tu? C'est en regardant la vidéo de l'émission Dragon's den de CBC que la confiance a encore grandi. Je suis un grand amateur de guitare, j'ai une dread de Boucher, une 00 de Claude Boucher, le maître en personne (fait dans son sous-sol), Une OM eastman...donc vous comprendrez que mes standards sont élevés. Première chose sur la confiance. J'ai parlé à M. Marr quelques fois et il était très bon en français, on conversait des bouts en français, des bouts en anglais. Un homme très sympathique. Shipping très rapide avec un setup de guitare A1. Comme les autres le mentionnent à plusieurs reprises, la guitare est emballée avec très grand soin, ça ne peut pas être mieux. J'ai commandé lundi(férié en plus), la guitare est arrivée à Rimouski jeudi. Première chose importante que je remarque en ouvrant la boite, la qualité du hardcase. Wow, un case de bien plus grande qualité que bien des guitares à 5000$, c'est le premier constat important qui m'a épaté. Quand j'ai ouvert le case, j'ai remarqué que celui-ci était vraiment sur mesure pour une 00, autre wow, car ils sont difficiles à trouver. Beau rembourrage, beau revêtement top. J'ai alors pris la guitare, elle est extrêmement légère et belle. Un beau fini mât avec une super belle qualité de bois. La tête est très belle et la découpe parfaite pour les cordes, éviter qu'elles accrochent comme sur plusieurs slotted head. La touche est parfaite et douce, le rosewood est super beau, tout comme le rosewood du chevalet pyramide...un autre gros wow. Maintenant, le son. La guitare sonne vraiment très bien, un bel équilibre, une grosse projection pour sa taille. C'est un charme à jouer. je l'adore. Je viens d'ailleurs de lui coller son pickguard (placé dans le compartiment de l'étui) afin de lui donner le super look Martin des années 1920. Je suis enchanté de cet achat, de la qualité de la réponse, de la qualité du shipping et sans nul doute de la qualité du produit. J’ai déjà plusieurs guitares Rosewood alors je cherchais vraiment de l’acajou, j’hésitais entre la Opeongo et la Toffino X, mais je préfère l’épinette au cèdre. Si vous n’avez jamais joué sur une 00, vous n’en reviendrez pas du confort d’une guitare comme celle-ci. Merci à vous messieurs Marr & Mackenzie, votre rêve, permet aux autres de réaliser le leur.

I recently purchased an Opeongo OO model guitar. I have bought high dollar guitars online before and they were not as carefully packaged as this one. The folks at Mackenzie and Marr made sure that it would arrive in pristine shape. The guitar was built well, it has a nice appearance and it has a great sound. Give these guitars a chance and I don't think y'all will be disappointed. Kelly W., Texas, USA

I play mostly electrics and semihollow guitars, and have for 30 years. I was looking for a high-quality parlor guitar for practice and small venues. My experience on acoustics is entirely with full-sized ones, and I could never find one which was flexible enough to get great tone for different playing styles. So I was very pleasantly surprised with the Opeongo’s tone for the different styles I like to play. It is crisp and bloomy when pick-strummed, doesn’t sound too boomy or bassy when thumb-strumming, and has really nice presence and body for finger picking. The body is very resonant, and you can really feel it when you do percussive picking. It just has a really balanced tone across the spectrum. Most parlor guitars tend to be 25” scale or shorter, but the 25.5” scale on the Opeongo provides more complex trebles that contribute to a very sweet sound. In terms of action and intonation, after a quarter turn of the truss rod both were quite suitable. In fact, the action is the best I’ve ever played on an acoustic - doing single note runs is only slightly more difficult than on my Heritage semi-hollow. The mahogany and spruce are high-quality, and being partial to open-pore finishes, the finish is for me perfectly minimalist. Fit is excellent, and looks high-quality. All in all, the Opeongo is a guitar that makes me want to play more.

Déjà 12 semaines que j'ai acheté cette guitare. Très satisfait de ma guitare Opeongo. Une sonorité surprenante pour une si petite guitare. Des matériaux de qualité et une facture impeccable une guitare très légère avec un substain étonnamment long que je trouve très inspirant pour mon style de créativité (je n'est pas trouvé le mot en français pour substain) Mes quelques amis musiciens qui en ont joués ou entendus sont très étonnés du petit prix que j'ai payé. Mon prochain achat chez Mac and Marr sera la guitare 12 cordes Algonquin. Très heureux d'avoir découvert les instruments de musique Mackenzie/Marr Merci John Santé Antonio

The Wednesday before Thanksgiving 2022 I was riding passenger from Austin Texas, up Rt. 35 to the Nations in Oklahoma to visit family. An ad came over my cell phone for McKenzie and Marr Guitars and just "hit me right". It said they were on sale and they don't sell through distributors. I would have never ever purchase a guitar over the internet...but I did. I purchased the parlor size with pick-ups and hardshell case. It was all against better judgement purchasing a guitar sight unseen...but I did. The 7 day money back warranty made me feel somewhat comfortable and I purchased through PayPal. When I got the guitar I opened the case without removing it so it would get up to room temperature. My first view of it told me I probably made a very good decision. After a few hours I held it, tuned it up and played it. The action was like a custom shop Martin. The sound was wonderful. I love this guitar. My friends who have played it agree. This company is the real deal. Totally excellent guitars.

When I first received the Opeongo and unpacked it, I was very impressed with the quality of craftmanship on the guitar. I was also impressed with the fine quality case. When I began to play I was a bit concerned that the tone was thin and reedy. That being said I found it so easy to play that I kept picking it up, and not surprising for a guitar made of fine quality solid wood, the tone changed rapidly, becoming deeper but still maintaining a clarity from note to note which is a real pleasure. I am enjoying this guitar a great deal. It is truly a fine bargain, a great value for dollars invested. Thanks to you at M&M !

I recently purchased the Opeongo as a replacement for my previous Parlor guitar and it has met my expectations (which were admittedly high). The guitar has great bass response and single string clarity making it an excellent choice for fingerstyle. There is a bit of buzz as noted by other reviewers on the thinner strings at the lower frets...although I am pretty sure it's cause the action is really low. I plan to raise the action a bit to set it up for some slide playing and expect it to shine there as well. A great guitar for a great price!

Initial impressions were that the action was generally good, although the nut height needs lowering (not a difficult diy). Was hoping the bass response would be better than my Wechter TO-8418. Different, but not louder. In the 2.5 weeks I've had it there is a buzz developing on the low F/F#. Not entirely sure what's causing it, but I'm a little worried. Trying to keep it humidified, which is not easy in the Arizona summer.

That Was Then

Back around the turn of the century (the 20th century that is), we'd sit down in the parlor after a hard day's work and pick out a few tunes. Those small body guitars were fun to play and sounded sweet. But time marched on - obviously to a different drummer - guitars grew in size to accommodate the need for "boomer" concert hall sound and our favourite OO size acoustics followed Gene Autry into the sunset. Building small guitars with a full, rich, resonant voice became a lost art. But............

This is Now

..........everything old becomes new again. The resurgence of small parlor style guitars is (pardon the oxymoron) huge. They're showing up everywhere, played by the cool dudes and dudettes. (You don't think Rodney Crowell is cool?). We first played a modern small body guitar made by a California company, whose name, looking north across Monterey Bay, shall remain nameless. It was love at first chord. But it wasn't cheap, and we quickly realized that OO guitars were either expensive and excellent or affordable and not very good at all. We took up the challenge of blending small with affordable and exceptional. It took three years, but we did it.
