Acoustics of Wood
Voichita Buchur
CRC Press, 1995
ISBN 0849348013

Voichita Buchur’s book Acoustics of Wood is a synthesis of over fifty years of work by the scientific community into the physics of how this complex material responds to vibrational wave stimuli. With almost 800 references into the literature and about ten years from inception to its being published in 1995, it is a tremendous resource for the luthier’s understanding of his/her main material. I don’t get the feel from the text that the author is a maker herself, even though she is a member of the Catgut Acoustical Society. The book is heavily weighted towards violin family instruments, but this doesn’t make the book any less valuable to guitar makers.

After a short, well written, general discussion on the anatomical structure of wood (macro, micro, and molecular), a brief outline is presented dividing the book into three major sections. Part One explores the physical phenomena associated with the effects of acoustic waves in forests (windbreaks to attenuate noise) and architectural acoustics (concert halls, office buildings, restaurants) with wood being used as a construction material and insulator in conjunction with other nonwood materials. A survey of six European concert halls and their geometrical, acoustical, and construction data is pretty interesting.

In Memoriam: Mario Martello

In Memoriam: Mario Martello

April 3, 1924 – October 2, 2006

by Richard Johnston

Originally published in American Lutherie #89, 2007

The luthier community lost a valuable resource with the passing of José Mario Martello. Mario, as everyone called him, was more than just a guitar repairman, although that was his primary trade for over half a century. Along the way, he built both classical and jazz (archtop) guitars, lutes, and made major components and modifications to banjos, mandolins, basses, and just about every wooden instrument that wore strings.

Born in northern Italy in 1924, Mario immigrated to Argentina with his parents when still a young boy. His father, Giuseppe, was a cabinetmaker, and while still in his teens Mario became familiar with fine woodworking from both the handcraft and the production vantage points. But an interest in jazz led him beyond furniture, and he apprenticed with a guitar maker making jazz guitars. Once married and a father, however, the uncertain political and economic climate in Argentina drove Mario to relocate to New York City in 1957, and, two years later, he tried the opposite coast and landed in San Francisco, where he quickly found work in a large furniture factory. When a coworker expressed an interest in building a guitar, Mario volunteered to help, which brought him to the Satterlee & Chapin guitar shop in the heart of the city.

Mario’s timing couldn’t have been better, for San Francisco was the West Coast’s focal point for the folk music revival. Virtually every known soloist and folk group filed through the many coffeehouses and nightclubs in and around North Beach. San Francisco was also home to a thriving jazz scene, including traditional jazz, and both flamenco and classical guitar were popular as well. Once Harmon Satterlee became aware of Mario’s skill and ingenuity, he was given a full time job as a repairman. Mario was called upon to repair and customize a wide range of instruments for amateurs, touring professionals, and everyone in between. Dave Guard’s Vega banjo and Segovia’s Ramírez guitar might cross Mario’s workbench in a single day, along with the Harmony Sovereign of the local Woody Guthrie wannabe.

This was long before the publication of any how-to books on instrument repair, or a helpful organization like GAL. Mario had to rely on his skills in fine woodworking, but even more important was his ability to trouble-shoot almost any problem and improvise a solution. It was this combination of talents that brought him to the attention of Jon Lundberg, who had opened a fretted instruments shop across the bay in Berkeley. Soon Mario was able to buy a home in the East Bay, turning the garage into a workshop and making weekly pickup and delivery runs to Lundbergs and a few other music stores as well. Although more involved restorations or customizations might take a month or more, most repairs were returned a week after he picked them up, and both the variety and volume of work he performed was staggering.

Jon Lundberg was the leading source of vintage acoustic instruments on the West Coast in the 1960s, and in the days before the mania for originality set in, Jon had Mario customize or modify many instruments. A new D-28 would be given an extended headstock to become a 12-string, while a huge Larson Brothers archtop, for which there was no demand at all at the time, would get a new flat top and become a Super Jumbo that made a Gibson J-200 look puny. Lundberg’s shop had other repairmen, but Mario’s wide-ranging talents made it possible for the shop to restore everything from antique Irish harps to Italian lutes.

Mario was typical of many fine craftsmen of his generation in that most of time he was content to work behind the scenes, often seeing others get credit for work he had performed. Although he was featured in local newspapers in Contra Costa County, he never received national attention despite his numerous restorations of guitars owned by famous players such as Segovia and David Crosby. But among those of us who knew him, Mario was always impressive. He was tall and handsome, with effortless and genuine Latin charm.

Mario remained active until the last few months before his death, playing bass in a jazz group as he had for years, and fixing instruments for many of the same dealers, musicians, and collectors for whom he’d worked for decades. He gave each repair job the same priority, and never put off completing a task. When he ceased working early in 2006 because of ill health, there were no unfinished jobs and no need for outside help to clean the slate. His diligence and inventive spirit should inspire us all.

Passed June, 2000

Originally published in American Lutherie #63, 2000 and Big Red Book of American Lutherie Volume Six, 2013

How well I remember the first letter we got from Nick. He told of being introduced at a party as a “Master Craftsman.” At first he was flattered, but was quickly brought back to reality when the local birdhouse tinkerer was also identified as a “Master Craftsman.” That was in 1982. Nick and I kept up a lively and voluminous correspondence for the next eighteen years. Nick was a GAL member for twenty-three years.

As a kid, Nick was in a rock band with his big brother called The Hatfields, and they actually put out a single in the ’60s. He also did a stint in a hippie combo modeled along the lines of Captain Beefheart’s Magic Band. His later musical taste ran to playing Japanese flutes. He worked as an amateur luthier, and then began the enormous project of singlehandedly building a good-sized wooden sailboat. He had completed a lot of the fittings and had a good start on the hull when a fire at the space he was renting deferred his dream. He often wrote of his plan to sail to Bora Bora and Tahiti.

But he did get around. He spent a summer hiking the Pacific Crest Trail, and recently he had discovered sea kayaking. He was an avid fly fisherman and had some articles published in fishing magazines. And remember the big hoo-ha about the Mojave Phone Booth a year or two ago? Nick was the discoverer of the Mojave Phone Booth. It’s a long story, but a well-documented one.

Nick was a GAL True Believer. We published many of his articles over the years, and he served for a time as an Associate Editor of American Lutherie. His academic and practical knowledge of botany and wood anatomy was particularly valuable. He was our go-to guy for all wood identification questions and was the major contributor to our book Lutherie Woods and Steel String Guitars. He had a special commitment to the Guild’s benefit auction, spending hours tending the preview at conventions, as well as donating many items and paying ridiculous prices for others.

The Guild owes Nick a particular debt of gratitude for talking me into getting e-mail, then hounding me into agreeing to try out a web page for the Guild. Back in the primitive 14.4k days of 1995, he developed the page, got it up on the web, and proceeded to maintain and improve it for another couple years, all as a volunteer. To date we have had more than 170,000 hits on our page, and half our annual income flows through it.

I only saw Nick a few times, at GAL Conventions and once when he came through town on a vacation. Still, he was a close friend. Our correspondence covered everything from God and Man to rock ’n’ roll.

They tell me Nick took his own life in the first days of June. I really can’t believe it. It just does not fit with the rest of the story. It seems a lot more like he’s finally off on that long journey to Bora Bora, and some day he’ll tell me all about it. I’m going to think of it that way.

In Memoriam: David Rubio

In Memoriam: David Rubio

December 17, 1934 – October 21, 2000

by Paul Fischer

Originally published in American Lutherie #65, 2001 and Big Red Book of American Lutherie Volume Six, 2013

Born in London, David Rubio was educated at Whittingham College, Brighton, and then studied medicine at Trinity College, Dublin, but gave up because of color blindness. His other abiding interest at the time was the guitar, and in particular, flamenco. Self-taught, he spent time playing in London coffee bars before deciding to go to Spain, where he played with traditional singers and dancers.

To supplement his meager income, he began trading wood between guitar makers and, in the process, learned something of the craft and art of guitar making. The hours spent in these workshops was not wasted, and what he witnessed and experienced, further enhanced by his photographic memory, would be put to good use some years later.

He was invited to go with the Rafael de Cordoba ballet company on a tour of New York in the early ’60s, and on completion of the tour, Rubio remained in New York, having met Neste, who later became his wife.

He had been born David Joseph Spinks, but during his time in Spain had acquired the sobriquet “Rubio,” a reference to his pale north European complexion. He later Hispanicized his second given name, Joseph, to José.

It was during this period in the early ’60s that he decided at first to repair guitars, then quickly moved to making them. Working from a garret in Greenwich Village, he built these first instruments on a chest of drawers using tools purchased from Woolworths. The guitars carried the label: “José Rubio Constructor de Guitarras.”

A stroke of good fortune occurred when Julian Bream brought him an instrument for repair and was much impressed by a flamenco guitar just finished.

By the mid-’60s Rubio had made numerous guitars and had a reputation as “the gentleman guitar maker,” a reference to his habit of working in smart clothes. When I joined him in 1969, he still wore a velvet crimson waistcoat and bow tie while working. The connection with Bream led to an invitation to return to England and to use a recently renovated barn on Bream’s estate as a workshop. Rubio warmed to the idea, and in 1967 moved all his equipment (by then very professional) across the Atlantic and took up residence in rural Dorset.

Much influenced by the instruments of Simplicio, Santos Hernández, and Bouchet, by the time he was settled in his new workshop in England, Rubio’s guitars had taken on an identity very much their own, and now carried the label, “David J. Rubio, Luthier.” Working closely with Bream, his reputation and confidence grew rapidly. But it was Rubio’s desire to have his own workshop, and by 1968 he had found a property in Oxfordshire requiring much restoration, but ideal for his purpose. With his usual concern for detail, a 15th-century house with barn was sympathetically converted into an ideal workshop and residence.

Since his early days in Greenwich Village, Rubio had moved back to England, changed workshops twice, and established himself as a leading guitar and lute maker in just five years. That, by any standards, was an impressive achievement and perhaps enough for most people, but not Rubio. At that time, the early music scene was burgeoning, and there was demand for good copies of historical instruments. This was why, in January 1969, I presented myself at his door, informing him that I was a qualified harpsichord maker seeking to extend my experience into fretted instruments. To my surprise and delight, he said his next project was to make harpsichords. When could I start?

Grass never grew beneath Rubio’s feet, so with my experience in harpsichord making, we began an instrument almost immediately and presented it to the customer some months later. Other instruments soon followed — theorbos, vihuelas, citterns, pandora, as well as lutes and guitars.

With the rapidly increasing demand for all instruments, two makers could never hope to satisfy demand, so the decision was made to build another workshop, specifically for harpsichords, and to use the existing one for small fretted instruments. The workforce was increased from two to nine, inevitably putting great pressure on Rubio’s time, so I became manager, which freed him to concentrate on his next project, bowed instruments.

Creating yet another workshop for himself, in 1972 he began making Baroque violins and cellos, later followed by viola da gambas. With his increasing interest in bowed instruments, only a limited number of guitars and lutes were made by him personally; most carried the initials P.F. and a smaller number, the initials K.S. (Kazuo Sato).

By the mid-’70s, Rubio’s thoughts had turned to his long-term future and a desire to return to working solo. In 1979, he left Oxfordshire for Cambridge. As the market for harpsichords declined, his interest turned to the modern violin, and these he continued to make until the last few months of his life. Parallel to violin making, he undertook research into the varnishing techniques of the Cremonese masters, as well as acoustic testing for guitars and other instruments. For this work, Cambridge University conferred on him an honorary master’s degree.

During his years in Oxfordshire and Cambridge he made a relatively small number of guitars and lutes, but come the ’90s, his restless energy brought him full circle and back to his first choice, this time to something of a hybrid among guitars, the 8-string guitar, but not in its more usual form. In collaboration with the guitarist Paul Galbraith, an instrument using an asymmetric fingerboard and bridge, such as was used on the orpharion of the 17th century, was developed and christened the Brahms guitar.

The many and varied instruments made by David Rubio will, of course, remain as a testament to his creative energy and talent, and so will the many younger makers who were influenced by his ideas, inspired by his achievements, and encouraged by his example.

David Joseph Rubio died of cancer in his workshop on October 21, 2000. He is survived by Neste, and his daughter, Benita, from an earlier marriage.

In Memoriam: Mario Maccaferri

In Memoriam: Mario Maccaferri

Passed on April 16, 1993

by John Monteleone

Originally published in American Lutherie #35, 1993 and Big Red Book of American Lutherie Volume Three, 2004

My first contact with Mario Maccafferri was fourteen years ago, the result of looking up Mastro Industries in the Yellow Pages. I already knew by then that he was the creator of the wonderful guitars made by Selmer of Paris which were made famous by Django Reinhardt.

His plant on Webster Avenue in the Bronx, a city block in size, was a shrine to a self-made man. The exterior of the building had the look of a factory built in the forties and dedicated to serious manufacturing. There were several large silos behind the factory which once held the many different colors of plastic pellets used in injection molding machines. The factory had many rooms and seemed to ramble on and on. Once inside, I walked into a room which once had forty huge molding machines running, each one the size of a locomotive. At this time there was only one of these machines in operation and it appeared to be the last gasp at the end of a long and successful, not to mention prosperous, era; The Golden Era of Plastics. I am referring to a special time of invention and pioneering, a time when Mario was a major contributor to the field of injection molding plastic. He proudly showed me the complete Mastro line of marbleized plastic wall tiles, clothes pins, toys, mosaics, clothes hangers, acoustic ceiling tiles and musical instruments. Mario was the holder of over fifty U.S. patents for these items and the processes by which to manufacture them. Among his many inventions, he was very proud of his plastic ukulele.

I discovered a warehouse room filled with several thousand guitars still sealed in their original cartons since 1954. There were many other rooms that were filled with all sorts of machinery and assembly lines. And there was the reed section. I was at that time unaware of the French American Reed Co. and its history. On the walls of Mario’s office were many personalized photos of all of the great saxophone and clarinet artists of the day. In the early years, the big band years, Mario ghost-manufactured reeds for every one of the other reed companies. It was there at one of the reed machines that I met Mario’s wife, Maria. She was a hard working woman of grace and beauty. And she was ready to revive the reed business that had gone by the wayside in the ’50s when the plastics plant was in full swing. But now, the plant was winding down all operations and Mario was retired and getting ready to take a rest.

I visited Mario quite often back then in the early ’80s. I would take the day off and jump in the car. After several visits he asked me if I could make him a guitar. He handed me a blueprint of his classical cutaway model. I was at the same time both surprised and eager to accept the challenge. While I was making this guitar for him, Mastro was getting ready to hold an auction. This was in November 1981. It was a sad time for him and Maria. Their whole life was on the block and before them, disappearing piece by piece. This was yet another transitional time in Mario’s life and I was there to watch it happen.

After I completed his new guitar I brought it to him. Upon seeing it his eyes lit up. And then I began to witness the intensity and devotion that he had when he was back in Italy, young and in his prime. Right away he wanted to make a change to the guitar to make it respond easier, to “wake it up,” as he would say. Without hesitation we went into the shop where he had retained some of his benches and tools from the auction hammer and I cut off the back. Time was of the essence so I was compelled to use a bayonet saw. I was sick about having to do this because I had used some of my best Brazilian rosewood for the back and sides. But there was no time to waste and it had to come off quick. And quick it did, ZIP! All of the fan bars were cut out and he made new fan set and glued them in and secured them with masking tape. We came back after lunch and made a new three-piece back and had it glued on with the tape. Masking tape was all that we had. We didn’t have any clamps on hand, since I hadn’t planned on operating so speedily on a guitar that I just delivered. Mario had it strung up the next morning and called me to tell me that it made a good improvement. We had a lot of laughs about it later on.

Well, that was the way it was with Mario, and I couldn’t have been happier because it soon got the juices flowing for the next project. I learned an invaluable lesson from him that it was more important to follow your instincts than to stand on pride alone. After a little prodding, I convinced Mario to make some wood guitars again based on his original designs. It was decided that we would make six classical and six jazz guitars. He had some forms for the back and side laminating but we didn’t have any veneers to work with. So we piled into the big green Cadillac and hot-footed it over to Constantine’s where we picked out enough Indian rosewood and poplar for the whole project. The next day I brought up some tools and clamps and we got right into it. The level of excitement was tremendous for me. I was about to learn first hand from the master himself how to make a Maccafferri guitar. And I could tell that Mario was feeling like a kid again and it helped him, I think, to get his mind off the retirement thing. Maria was happy to see him get involved in something constructive.

Mario and Maria always went to work together every day since they first met back in 1936. He regularly wore a suit and tie to work. And right up to 1993 it was no different. I will never forget the great times that we had. Lunch time was usually a time to relax in Mario’s office while Maria would prepare a simple continental lunch for the three of us. There was always a guitar handy and Mario would play. His talents extended beyond the workbench as well. Not many people were aware of what a great guitar player he was. His style was very classical, romantic, melodic, and confident. His technique was impressive, to say the least. It was such an honor to not only make guitars alongside one of the greatest figures in the guitar world, but to be serenaded by him too. I cherished those lunches with just the three of us. After coffee, desert, and guitar talk, we were off to the shop again to see if the glue was dry yet. He carried one of those little metal aspirin boxes in his pocket that jangled with his every step. Inside the box were his heart pills that he must have been taking for the last forty years. He also loved hard candy and always had one for each of us after lunch.

It was Mario’s wish to go into the guitar business and he offered me his cooperation, his plant, and his name. I faced an extremely difficult decision. Was I going to make Maccafferri guitars, or Monteleone mandolins and guitars? I decided to follow my own destiny, but not without utilizing my experience with Mario. His designs were a big influence on the Hot Club and Django models that I went on to produce later. Although I went on my own I remained in close contact with Mario and continued my visits to the Bronx.

All of those people who knew Mario were constantly amazed by his level of energy and great stamina. Once we had finished making the twelve guitars, I showed Mario my first violin that I had just completed. His reaction was to show me his secret stash of four sets of violin wood that he had brought with him when he escaped from Europe in 1939 just before the Germans invaded France. His face lit up once again and we were suddenly in the violin business. This renewed interest in the violin instantly sparked an old challenge in Mario. He had always wanted to make a plastic violin that would posses all of the finest attributes of a fine old Cremonese instrument. With this in mind, he drew a set of prints for the molds and went to work without hesitation. He was by then only 88 years old. He debuted the first plastic violin at Carnegie Hall on March 8, 1990.

Mario continued to pour all of his concentrated efforts into further developing the plastic violin until his dying day. He was disturbed by the fact that he could no longer play the guitar. His age was beginning to catch up to him after the move of the plant to Mount Vernon. He didn’t let it get him down. He would always call and say to me, “Can I come and work for you?” I would take it as a compliment and then think to myself, “If only we had met fifty years ago!” And then I’d imagine, “What if?”

I had always thought of Mario going on forever. No one expected it to end so quickly.

Time has its own way of doing things and it finally caught up with Mario Maccafferri on April 16, 1993. At his funeral, from the choir loft, a solo violin (the same one that was played at Carnegie Hall) touched our hearts with some of the pieces of music that he loved to play on the guitar. It was a befitting farewell and tribute to a friend who gave all he could to anyone who was willing to listen.

I often think of Mario as I go about my work. It’s like he’s there working with me sometimes. It was the greatest privilege of my life to have known and worked with him. It was an experience that I will never forget.

Mario leaves behind his beautiful and loving family. He was very close to them, especially his Maria. We all adored him. And we shall all miss him.
