A Galloup guitar made from paulownia.
Our columnist investigates whether new wood materials like paulownia can steer lutherie through an environmentally uncertain future.
The tonewoods we choose for Galloup Guitars represent some of the finest available, selected for their exceptional sound quality, stability, and long-term reliability. These materials are integral to crafting instruments that offer outstanding performance and make for wise investments for our customers. To ensure the highest quality, I personally travel to Europe to handpick premium-grade soundboards from regions known for producing world-class tonewoods. These soundboards are reserved for high-end, concert-level instruments and are often unavailable in the broader market.
Guitars priced between $1,500 and $4,000 typically utilize domestic woods or other widely accessible alternatives that provide excellent value. However, in recent years, sustainability has become an increasingly critical concern regarding the sourcing of these natural resources. We are committed to ensuring that the materials we select not only deliver superior sound but also align with sustainable practices, helping to preserve the environment for future generations of musicians.
Over the years, Iāve encountered difficulties with alternative, sustainable soundboard options. That is, until I took part in the paulownia experiment initiated by World Tree, an environmental organization āfocused on nature-based solutions to some of our biggest global challenges.ā This project highlighted wood from the fast-growing paulownia tree, which was cultivated by former President Jimmy Carter. Initially, the prospect of using paulownia appeared impractical. Yet, upon further analysis, we recognized its potential as a viable substitute, though some of its material property characteristics, such as damping and admittance, still require further testing.
Many luthiers understand traditional soundboard materials well. Despite this knowledge, integrating new tonewoods into our repertoire can be an arduous process. Fortunately, advancements in wood testing technology have significantly expedited the evaluation process. Currently, for the assessment of wood, I use the Acousonix Sonic Calculator, a handheld application that enables me to input various wood-property parameters for a thorough evaluation. Upon entering the data, the application delivers a precise rating, considers multiple factors, delineates the wood's sonic characteristics, and then specifies its best use applications.

My Acousonix analysis of paulownia indicates that its 11.3 sonic rating makes it unexpectedly well-suited for use as a soundboard (see Fig. 1). As my builds with this material progressed, the results were exceedingly promising. Paulownia features well-rounded tonal characteristics, exhibiting a rapid response with a seemingly high admittance, which indicates a lower damping factor. Another noteworthy aspect of paulownia is its sustainability: The tree reaches full maturity in approximately 12 years. Upon harvest, a new sapling can be replanted in the same root system, allowing for accelerated mature growth in around seven years. This cycle can be repeated multiple times, establishing paulownia as a highly renewable resource. But unlike typical spruce, which commonly yields eight to 11 growth rings per inch, paulowniaās growth rings come in at around three to four per inch. But donāt let this fool you. Despite its non-traditional appearance, paulownia has a reputation for being stable and warp-resistant (see Fig. 2).

While testing paulownia for guitar making, we observed that this species yields a highly responsive instrument. It offers a fast musical response similar to many late-1930s Gibson J-35s I have played. It exhibits a quick response with a lower fundamental and a pleasant decay. But, due to its lightweightāaround 5 grams per cubic inchāit tends to exhibit lower headroom. Thus, despite being a powerful and enjoyable guitar to play, it tends to distort when pushed to higher volumes. In its defense, most players commonly donāt play hard enough to reach these limits.
Ultimately, the tests I conducted affirm its potential as a substitute tonewood for guitars, possessing desirable acoustic properties. While paulownia has historically been utilized in instruments like the Japanese koto, it stands to reason that the acoustic guitar market should explore this avenue further. To prove a point, we used paulownia for the top, back, sides, bracing, and neck, with the total price tag for all tone woods used coming in at around $70. So, given its low cost, stability, availability, and the grower's commitment to environmental sustainability, paulownia is a resource deserving of serious consideration.

Restoring a Romantic-Era Acoustic with Ties to the U.S. Presidency
These before (left) and after (right) shots demonstrate only a fraction of the restoration process our columnist carried out.
This centuries-old instrument, which belonged to the daughter-in-law of President Andrew Jackson, has witnessed almost 200 years of American history.
We tend to think of āhistoryā as something we read about or learn from our elders, rather than something we live and contribute to. Iāve often wondered if my great-uncle knew he was making history when, as a Mexican immigrant, he built the original Mickey Mouse guitar for Walt Disney in the early 1950s.
Last year, I was contacted by Jennifer Schmidt, the collections manager at Andrew Jacksonās Hermitage. They were seeking a grant with the hopes of restoring an acoustic guitar on the property. It was the guitar that was owned by Sarah Yorke Jackson, White House hostess and acting first lady of the United States from November 1834 to March 1837, and daughter-in-law to Americaās seventh president, Andrew Jackson. The Hermitage is the historic home of President Andrew Jackson located in a neighborhood just east of metropolitan Nashville.
When I arrived at the home to inspect the guitar, it was leaning against a chair in the living room, in desperate need of repair. It had been ārestoredā previously by a violin luthier in 1983, and while their work helped sustain the shape of the instrument, there were many repairs that had been done incorrectly.
I quickly saw that this was going to be a combination of a restoration and preservation project. There was a history written up on the guitar, but I believe it to be incorrectly documented that the luthier was Cabasse-Visnaire l'AƮnƩ, who worked in the Mirecourt region of France during the early 1800s. Despite bearing some similarities, later guitars that are credited to Cabasse-Visnaire have a different style in building.
Based on the design, I believe the instrument was crafted by Petitjean l'AĆ®nĆ© in 1817. Another luthier from the region, Didier Nicolas l'AĆ®nĆ©, was also active in that period, but there are differences in his building decisions that have led me to this belief. Didier was known for his one-piece maple backs on his guitars, while Petitjean l'AĆ®nĆ© was known for laminating the backs of his guitars, and this guitar has a spruce back with a laminate. He also built in a style that was complementary to Didierāa nice way of saying he appears to copy his style in headstock and design.
āI couldnāt stop thinking of the story this instrument could tellāall it had endured and been privy to, the suffering it witnessed and the joy it gave.ā
This guitar is considered a āRomanticā guitar, made during the era of 1790 to 1830. It features a Norway spruce top, most likely harvested in the French alps. The fretboard is African ebony, with a 646 mm scale. The back is laminated spruce and the sides are rosewood, with the outer laminate appearing to be pearwood.
The guitar needed a great amount of work. The issues and repairs included top cracks, loose perfling and braces, bridge lifting, binding and inlay missing, separated back, missing and incorrect frets, neck reset, missing top-hat pegs, and, to top it off, a fretboard held on by Scotch tape. When the instrument was finally delivered to us, it took several months before I could clear my schedule to dedicate time to the repair. The repair itself took several weeks to complete, but I couldnāt stop thinking of the story this instrument could tellāall it had endured and been privy to, the suffering it witnessed and the joy it gave to either Sarah while she played it or the audience she may have played it for. As musicians, we all tend to think beyond just the physical attributes of a musical instrument. We use words like feel, touch, voice, warmth. We use these terms because the instrument is expressing something that we lack the words or ability to express without it.
This guitar lived through the formation of the Democratic Party, the origins of the Spoils System, and the Indian Removal Act, which created the Trail of Tears. All of the pain and suffering, as well as the victories and joys, that were absorbed into this instrument have shaped its sound and presence, and to think that it crossed my path, a first-generation Mexican-American born in the United States. I am honored at the opportunity to help preserve a small piece of our American history.
I have worked on countless instruments that have historic musical relevance, but this guitar was different. We have a tagline for Delgado Guitars: āDoes your guitar have a story?ā I created this tagline because I believe every person has a valuable and important story to tell. Now, Iām grateful to have helped preserve this amazing guitar for future generations to see as they visit the Hermitage. I even built a custom stand from wood that came from the property. You can see more of the steps in the restoration on our social media pages if interested, but if you find yourself in Nashville, please stop by the Hermitage and pay it a visit. It might inspire you to share your story.

Pacific Island pluckers had a hand in developing the beloved dreadnought acoustics, and changed the course of American guitar music.
In 1906, a devastating earthquake and three days of raging fires leveled 80 percent of San Francisco. Nine years later, to honor the opening of the Panama Canal and signal that San Francisco was back, the city held the Panama-Pacific International Exposition.
More than 18 million people visited. One of the most popular attractions was the Hawaiian Pavilion. Live music and hula dancing, integral parts of Hawaiian culture, were in the show, where they could be experienced on a large scale on the mainland for one of the first times.
That was the beginning of the Hawaiian music craze that had a good run in the U.S. until the Great Depression. Hawaiian musicians had already embraced the ukulele and steel-string guitar, originating the slide-based lap style (versus the typical, so-called Spanish-style playing orientation). Both instruments saw unprecedented demand on Hawaii and the mainland. The story of the ukulele is well-told, but in doing research for this article, I came across a funny comment that caught my eye: āIt could be said that in the mid-1920s, Martin was a ukulele company that also made guitars!ā
In early 1916, we made a large-body custom guitar for Hawaiian musician Major Kealakai. He ordered it through our largest distributor, Ditson. It was kind of a 0000-size, 12-fret, steel-string guitar with an extra-deep body. The Major and his band were touring the U.S. mainland, and he felt he needed a bigger, louder guitar.
Shortly after that, Ditson commissioned a new larger, pear-shaped steel-string guitar from us to capitalize on the growing interest in Hawaiian music. It was called the dreadnought. It had just 12 frets, a slotted headstock, and a sizable, resonant body. Initially, the dreadnought didnāt sell very well. We did find success, however, making many of our smaller-bodied guitars with steel strings set up for āHawaiian-styleā playing. These were often made with a koa-wood back and sides, and occasionally tops as well. Additionally, if players wanted to use our other guitars lap-style with a slide, Martin manufactured a nut extender to raise the strings far enough above the frets so they wouldnāt interfere.
āIt could be said that in the mid-1920s, Martin was a ukulele company that also made guitars!ā
While steel strings were available in the late 1800s, the quality was inconsistent. Thanks to the popularity of the banjo and the mandolin, steel-string quality improved. The steel string provided the extra volume many players were looking for.
During the Great Depression, Ditson suffered financial difficulties and was sold. We kept the dreadnought in the line and put the Martin name on it, but sales still remained low. In 1929, we made a one-off, 14-fret steel-string version of our 000-size guitar for a well-known vaudeville banjo player, Perry Bechtel. We squared off the shoulders to accommodate the 14-fret neck. He loved itāand we thought we were onto something.
Gibson also saw opportunity in larger-bodied guitars with steel strings and 14-fret necks. They introduced three new models in 1932: the HG-20, HG-22, and HG-24. The first two were slightly smaller than our dreadnought, and the third was slightly bigger. They realized the value of a 14-fret neck for modern playing styles with steel strings. But instead of squaring off the shoulders, they moved the bridge down and attached the neck to the slope-shouldered bodies.
Not only did those models have a traditional round soundhole, but they also had four f-holes and a sound baffle to try to compete with the newfangled resophonic guitars that were quite loud. But the Gibsons were not well received by consumers, and were eventually discontinued.
In 1934, we redesigned our dreadnought with square shoulders to accommodate a 14-fret neck. That same year, Gibson reintroduced the HG-24 body size with a single round soundholeāno more f-holes or sound baffleāand called it the Jumbo. The Martin Dreadnought and the Gibson J Series guitars are still wildly popular.
I do wonder if they would even exist today if Hawaiian music hadnāt entered the American-pop music sphere in the 1920s?
