Small Group Guitar Building

This is an inexpensive way to learn guitar building so don’t miss out!

In this class a maximum of 4 students will be able to watch Robert as he builds a classical or steel string guitar in his shop. The guitar will start from raw materials and progress to a ready to play state, but without a finish, in 5 days. Ask questions, take notes, shoot unlimited photographs. You will be able to participate in some steps of the construction process.

This is an opportunity for those who have already built guitars to study Robert’s building style and improve your skills. For those considering making a guitar, this class is a good way to explore the idea of building a guitar before jumping in for the first time. The guitar will be for sale at the end of the class at a discount over Robert’s commissioned guitars.


Soundboard Voicing: Classical and Steel String

This is the Holy Grail of guitar building! In this class you will thickness, brace and voice a soundboard with Robert. This can then be taken to your shop and used as a reference for future soundboards or you can use it on a guitar. Learn about the optimum thickness for the species of wood you are using, what a loose or stiff top is, different radii and how they affect tone and structural integrity, bracing patterns, how to thickness soundboards with hand tools, how to select tonewood, and much much more!

There is some prep work for you before coming to class. Students need to join and thickness two or three soundboards to approx 3.5mm. If you plan on using your soundboard on a guitar you may also install a rosette. Bring the soundboards and bracewood to the class. Robert will then evaluate and critique your materials and help you choose the best one to work with. He will then work with you to thickness, brace and voice the soundboard so that it will give you the best response when used on a guitar.

Although there is something for everyone to learn in this class it is best if you have already built at least a couple of guitars.


Double Tops

So, what’s all the fuss about double top guitars? Learn about the advantages that double top technology has to offer to you as a builder. This modern approach to guitar building uses a thin inner and outer skin with a composite honeycomb material known as Nomex in between. In this class you will learn how to thickness the inner and outer skins and then use vacuum and adhesives to build your own double top. Bracing patterns, thicknesses and other issues associated with double top guitars will be discussed. You will leave the class with your own double top that can then be used on a guitar you build.

$1500 Includes materials

French Polish

Learn one of the most beautiful and least hazardous finishes used for centuries on guitars and high end furniture. French polish is a method of applying shellac, which on a guitar, is thought by many to yield the best tone of any finish. It is thin, flexible and lustrous. It is also very easy to repair. Traditionally a tedious application, Robbie’s method, championed by Richard and Marshal Bruné in Chicago, markedly shortens the process, so it can be completed in a few days. In this two day class you will learn surface prep, pore filling and how to apply a French polish finish that can be rubbed out to a high gloss or satin sheen. Class will be held 4 hours each day.


Guitar Building Consultation

This service is directed to guitar builders who are stuck, need help only from time to time, or want to get better at a specific skill.

Maybe you just need a master luthier to guide you through a step while you perform it in his shop. Spend an hour or more with Robert, and one or two other luthier friends, if you like, on a topic of your choosing. Finishing, fret work, bridge glue up, voicing, set up, and more. He can demonstrate it, talk about it, you can do it. It is your custom lesson. Robert particularly encourages luthiers with less than 10 guitars to their name to bring their tops in for voicing guidance. Voicing is one of the few steps in guitar building that a book can not adequately address. Robert has voiced well over 600 tops, both steel string and classical. Certain steps in guitar building are forever, and voicing is one of the most critical. Let him share his experience with you for an even better guitar.

$85/hour (one hour minimum)

Sharpening Planes, Chisels, Spokeshaves and Scrapers

Dull tools make woodworking a miserable and more hazardous experience. So impressive are truly sharp tools that most woodworkers can still remember the first time they used a perfectly honed blade. Contrary to popular belief, it is rare to have a chisel or plane ideally sharpened out of the box, even from the best manufacturers. Learn how to make your hand tools glide through wood. Once properly sharpened, woodworking with hand tools becomes a joy and resharpening a breeze. Until then, you will wonder what you are doing wrong. Bring your tools to this class and put a razor sharp edge on them!


This schedule can change often. Be sure to check back often to see who’s coming to town, or put yourself on the O’Brien Guitars mailing list.

Rosette Making

June 10-12 Traditional rosette making is an art that has been passed down from artisan to artisan for centuries.  In this class you will learn how to design, make and install rosettes. Also learn how to make rope, wheat and herringbone purflings.


Modal Tuning with Trevor Gore

July 10-12 Luthier Trevor Gore, from Sydney Australia, will once again come to the O’Brien Guitars shop and share his knowledge and experience with Modal Tuning. This is a rare opportunity to study with an expert in the field of guitar acoustics and design. Last year’s class filled quickly. You will not want to miss this class. Topics covered include:

  • How strings drive your guitar
  • Visualizing and understanding modes of vibration
  • Relating modes of vibration to guitar frequency response curves
  • Measuring frequency response curves
  • Relating frequency response curves to generic guitar types (classical, flamenco, steel string rhythm, steel string finger picking)
  • Introduction to theory of modal vibrations
  • Mechanical impedance and admittance
  • Targeting the “right” modal frequencies and avoiding the wrong ones
  • Requirements of a guitar as a static and dynamic structure
  • Measuring material properties so that you can make the best of the wood you have rather than wishing for the wood you would like
  • Bracing schemes for backs and tops
  • Practical tuning of guitar modes: Moving from “as built” to “to design”

Robbie, thank you for your help Sir. You made all the difference in the world. You kept me from making mistakes and helped me around the ones I made. You are a great teacher and I sincerely appreciate your help. Barry
See what others are saying


Your teaching skills are top notch and you obviously put the effort into melding with the students you are presented with. You made us feel very comfortable and we had the best time working with you and being welcomed by your family. The kicker is our wonderful guitars we brought home. I haven't, and don't expect to find a better sounding classical than the one I made with you. Dave and Lisa
This has been an awesome week for me! It has been a great deal of fun building this guitar with Robbie and I've been learning a great deal. I am shocked at how quickly the guitar came together. I have a few years of experience building furniture (though as a hobby; I make about 3 pieces per year) but this is my very first guitar. Martin in San Diego
Robbie, Thank you so much for everything. This was such a wonderful week for me. I really enjoyed drinking from the fire hose of your guitar knowledge. I've had a hard time just getting off my ass and building a guitar and this class was such an effective way to push myself to do that. I suspect I could have learned much of this on my own--by building a couple dozen guitars--but I feel like you have given me a shortcut to competency as a builder. I would recommend his class for anyone that can take it. It really was such an effective way to get my feet wet. I hope to build a classical some time with you too. Martin in San Diego
“I think O’Brien Guitars hits the best balance of price, accessibility,breadth of offerings, quality of instruction and production out there.”
“Robbie is so accessible. I'm lucky as he's in Colorado and I've gone to his shop a few times, but he's always there via email, phone etc. And no matter what idiot thing I've done, he doesn't ever make me think he thinks I'm an idiot. Superb teacher!
“I have spent many hours with Robert O'Brien and other Luthiers that offer lessons/classes. I have learned the most, and feel (by far) the most confident with Robert O’Brien. The primary reasons are clarity of lessons, presentation and variety of topics.”
My guitar looks, feels, and sounds great. It is definitely the nicest sounding guitar I have ever played. I am looking forward to making at least two more, one for each son. John
When someone, such as yourself, is a grand master of their craft they often can’t relate to the complete novice. That is definitely not true for you. Your teaching is exceptional and you have the rare talent of being able to convey complex and intricate procedures in a concise, friendly, easily understood and often amusing way. Alan
A shout to Robbie O'Brien and O'Brien guitars. I just showed my guitar off to 2 friends, both magnificently skilled musicians. The reviews were SO positive and they both thought it looked and sounded amazing. Thanks again Robbie for your guidance and patience. Bruce
I can't say enough how much I enjoyed the steel string voicing class yesterday and today, and how much I learned from it. Peter
I just had one of the best two days of my guitar building experience! While I have built over fifteen tops so far, I was always “guestimating” the sound and flexibility I was looking for. Being with Robbie and the other students helped me to develop an ear for the sound I was going for and a feel for the flexibility I was after. While I knew about putting a top together, hearing and feeling the progress of getting the top to where I wanted was just what I needed. In addition, the table talk about other aspects of guitar building, the questions/comments from the other students and Robbie’s answers, as well as the extra comments from Robbie about other aspects of guitar building was worth twice as much as I paid for the class. Robbie’s teaching style is stellar. He is clear and concise about the tasks we needed to perform. He is as easy going as can be but kept the class progressing as needed. I felt as a welcome guest in his home/shop and Adrianna’s hospitality made me feel pa John
Robbie’s teaching style is stellar. He is clear and concise about the tasks we needed to perform. He is as easy going as can be but kept the class progressing as needed. I felt as a welcome guest in his home/shop and Adrianna’s hospitality made me feel part of the family. And I even got a cool hat out of the deal! I highly recommend taking this class to anyone who needs to learn or improve their top building/voicing skills John
I took the Classical voicing course in June. The best guitar related money I've spent. Chris
You have caused a dilemma with me. I am being 100% honest when I say the playability and cutaway make this the guitar I want to play every day. I love the sound. I think the French polish and redwood give it a pleasing tone and of course everything else that goes into it. It's easier to play then my Hauser. Jon in Pennsylvania
The quality of your work and training is really superb! Sean - United Kingdom
If you really want to understand traditional flamenco guitar building Paco’s course is a must. And with Paco and Robbie you get two genius instructors for the price of one and a hand built true flamenco guitar as well. What an extraordinary and fun experience. Thanks again Paco and Robbie. Richard
You're a terrific teacher on-line. I can only imagine what it's like to be in your shop. Alex - Brazil
Both the voicing and French polishing classes were great -- lots of new information and skills to work on. It was well worth the time, travel, and expense. And thanks to your family for their hospitality. Stephen
I built a guitar with you in November of 2017, and I imagine that you have so many students and meet so many people that it is unlikely you remember me, but I wanted to let you know that my steel string guitar is sounding better and better as time passes. My guitar teacher says it is one of the best sounding guitars he has ever heard and he is not prone to hyperbole. Also, I sing your ( and your school’s) praises whenever anyone asks me about the guitar. You never know, you might get a new student out of it. Take care. Jerry
I built a guitar with Robbie a couple of years ago, and it is fabulous and getting better all the time. Robbie is great and his instruction is the best. Jeff
I can't imagine anyone being more qualified to instruct in the field of Lutherie. You definitely have a talent for keeping things interesting. Roger
I want to thank you for an amazing week. The guitar built with you over that 6 day period exceeded my expectations. This class was the fulfillment of a desire to put my 2 favorite hobbies together - guitar and woodworking. The guitar looks and sounds fantastic. After playing it when I got home, it felt like an old friend already! Jon
Just a note to let you know how much I'm enjoying the guitar - getting better and better and a joy to play...and how much I enjoyed our build - I learned a ton...thank you! Will
Building a guitar With Robbie is an exhilarating experience. One feels comfortable from minute one, as he shows you his straightforward, methodical approach. He is extremely patient and never gives the apprentice a hard time. Pedro - Brazil
I attended Robbie’s class this December and couldn’t be more pleased with the experience and the outcome. We started with a box of beautiful materials from LMI and 6 days later I walked out with an outstanding OM steel string acoustic guitar. The class moved right along but not so fast that I did not have time to soak up lots of knowledge and new skills. Whether you are a musician looking for a custom guitar that fills all your wishes or a seasoned builder wanting to learn more, Robert’s class delivers. I highly recommend his class and look forward to working with him in the future. Dave
I can’t say enough good things about Robbie’s class David
I recently took a class with O'Brien Guitars. A one on one build for an OM cutaway with his simplified French polish finish. I can't say enough good things about my experience. Robbie was very knowledgeable and I learned some good tips/tricks for my future builds, his modified french polish was very simple at least in person. I imagine it will take me a few guitars of doing it on my own to master it but it certainly took most of the complexity out of a French polish finish. P.s I couldn't wait for the opportunity to say just a skosh lol David
I hope you remember me from a number of years ago when I studied classical guitar making with you. I owe you many thanks for all the things you showed me especially for showing me how to to things by hand and with out a bunch of fancy jigs and tools. I can’t help but think about you every time I’m in my shop building guitars and I’m always grateful for all the nice tricks you showed me. Bryan
You're a really good teacher. I was fortunate to have good shop teachers in K-12. You're right up there with the best. Fred
Your teachings have given us the ability to give voice to a tree. That voice then is able to express emotion without words. Our guitars radiate love, life, memories and healing frequency that everyone around can benefit from. Your teachings are priceless, and we luthier students are grateful. Abe
What a unique experience it is to finish a course with Robbie and always take home a fine guitar. Richard
I just finished building a classical guitar with Robert O’Brien today. It is difficult to tell just how thrilled I am with the result. Robert is an absolute joy to work with. He is both entertaining and professional at all times. Dan
I had been trying to find an opportunity to take this class for years, but it was always full. This time when he announced a cancellation, I jumped on it. I strongly recommend to anyone who is considering taking a class to do so now. Dan
I remember this and how amazed I was by the efficiency of it all, without ever feeling rushed. Thanks for the memories. The guitar I built there is still my favorite. Unfortunately it is still better than the ones I have made subsequently. Still practicing! Allen
I like your common sense approach to guitar building and that you don’t take things too seriously, it has really helped me. There’s a lot of hype and BS out there... you teachings are practical and concise. Bruce
Just want to say that in the first three hours of the Steel String Voicing masterclass today, I feel like years have been taken off my learning curve! Thank you! RandyJ
Robbie, thank you for the excellent classes the past several days. I leave them both with more than I had hoped for, both knowledge and experience. Not only did I learn your French polish technique, but SO much more! Thank you. Randy
Had a great time at your workshop, and I learned a LOT. In fact, I learned as much from the off-topic discussions as I did from the course material. I also appreciate the hospitality you and your wife showed us! Thanks, again! Marty
Brazilian Rosewood guitar built at Robbie O'Brien's shop . Hasn't left my side. Left all the rest behind Zef
Robbie, thank you for your help Sir. You made all the difference in the world. You kept me from making mistakes and helped me around the ones I made. You are a great teacher and I sincerely appreciate your help. Barry
Thanks again for this wonderful experience. I woke up early and spent a good hour and a half playing on my new guitar. It responds so well to my touch. Diego
Robbie O’Brien, you are the most unbelievably energetic and comprehensive teacher in the entire History of lutherie. You are an incomparable source of craft wisdom and know-how. Thank you for being alive on Earth and doing what you do! Stephen
Robbie, you are an awesome teacher and luthier. I have learned so much from you In a few visits. Dana
I want to thank you for an amazing week. The guitar built with you over that 6 day period exceeded my expectations. This class was the fulfillment of a desire to put my 2 favorite hobbies together - guitar and woodworking. The guitar looks and sounds fantastic. After playing it when I got home, it felt like an old friend already! I already can’t wait for the OM build next year. Jon
You’re a superhero! Thanks for all the great YouTube videos, your website, courses, GAL interviews and articles, etc… you’re awesome! Bryan
You are one of the best teachers and communicators out there without doubt. Francisco - Spain
Thanks again! Nathan has been playing nonstop since we’ve been back to the hotel. Awesome guitar! I hope to be back before too long for another set of lessons. You’re an awesome teacher, and your knowledge, experience and confidence, are very impressive. Chuck
The guitar my dad built with you really sounds amazing, better than the Martin D15 or Taylor 314CE we have. The level of clarity the mids and highs have is really unmatched to anything else I’ve ever played. It’ll be the main studio recording guitar for years to come. Thanks for having us and giving us the opportunity to create such an amazing instrument! Nathan
I have wanted to learn more about French polishing for a long time. Your presentation and working with me has raised my finishing skills by so much, thanks for sharing your skills with us. Jim
If you are at all thinking about learning to build a guitar you should strongly consider studying with Robbie. Stephen from Montana
This was one of life’s experiences I’ll remember clearly for a very long time… playing an instrument you’ve personally built has a special feeling. It’s an experience shared by a precious few. I’m happy to have become one. Thanks Robbie! Jim from Maryland
