Ren Ferguson Co. × Advance Guitars Signature Lineup
"The pinnacle achieved by the world's premier luthier, 'Ren Ferguson'"
Who is the legendary luthier, Ren Ferguson?
When discussing the history of modern acoustic guitars, one cannot avoid mentioning the name Ren Ferguson.
Formerly a master builder at the Gibson Montana factory, he dramatically revived the struggling acoustic division, and later demonstrated his expertise as chief engineer of Fender’s acoustic division. His contributions to the industry can be said to have ushered in a “golden age” for the modern acoustic guitar market.
■ A figure who cast “magic” on the guitar once again in an era of advancing science and efficiency
To truly convey his greatness, we need to take a brief look back at the background of the acoustic guitar industry at that time.
From the 1970s through the early 1980s, before Ren joined Gibson, the company’s acoustic division was going through a very difficult period.At the time, the top priority was “making sure they didn’t break,” in order to prevent warranty claims and repairs. As a result, the wood was thick, and the internal bracing was designed to be excessively rigid. Consequently, the vibration of the top—the very lifeblood of an acoustic guitar—was suppressed, leading to a situation where the instrument’s rich, natural resonance was lost—a complete reversal of what an instrument should be.
It was Ren Ferguson who emerged to break through this slump. He reviewed all previous blueprints and returned to the labor-intensive pre-war “ rich-sounding structure.”The passion of a single craftsman revived a prestigious brand that had been on the verge of losing its former glory. It was also the moment the brand reclaimed its pride in its mission: “to build the world’s finest acoustic guitars.”
Furthermore, to clearly illustrate his position, I would like to deliberately highlight his “polar opposite.” That person is Bob Taylor, the founder of Taylor Guitars, another top brand in modern acoustic guitars. Bob Taylor was an early adopter of computer-numerically controlled (CNC) machinery and bolt-on neck joints, establishing a remarkable engineering system that ensures “perfect, consistent quality every single time, regardless of who builds it.” He is truly a revolutionary figure who elevated guitar-making to the level of precision manufacturing.
If Bob Taylor “scientifically” engineered the acoustic guitar, then one could say that Ren Ferguson is the one who has re-cast “magic (art)” upon the acoustic guitar once again.
As a wave of efficiency swept through the entire industry, Ren chose to steadfastly preserve traditional, labor-intensive methods such as “hide glue” and “dovetail joints.” Rather than making everything uniform, he keenly discerned the individual character and expression of each piece of wood and hand-carved it (voicing).In this way, he passionately drew out “the ultimate tone and soul unique to that guitar.” This was the very embodiment of the theme Gibson championed at the time: “Tone, Feel, Appearance.”
Typically, crafting such “one-of-a-kind” guitars—true works of art—is considered the domain of individual luthiers who can produce only a handful of instruments per year. However, what makes Ren truly remarkable is that he achieved this pinnacle of quality within a large factory employing hundreds of craftsmen. He was not only an artist with exceptional technical skill but also a brilliant leader who guided his team of craftsmen.By changing the mindset of each individual craftsman and sharing his own techniques and philosophy with the entire team, he produced one masterpiece after another—guitars that could be called “miracle instruments”—right from the mass production line.
■ The Artisans Who Saved Two Major Brands:
In addition to the differences from Bob Taylor, there is another figure who is indispensable when discussing Ren Ferguson in the history of acoustic guitars. That person is Mike Longworth, a craftsman who made a tremendous contribution to the history of Martin, which stands as a counterpart to Gibson.
While both were pivotal figures in supporting America’s two major acoustic brands, there was a clear difference in the “roles” they played within their respective companies.
Mike Longworth was recruited by Martin in 1968 to revive the pre-war top-of-the-line “D-45” model, which had been out of production for some time. He oversaw the intricate pearl inlay work and masterfully brought the D-45, the pinnacle of the brand, back to life.Furthermore, he thoroughly researched Martin’s history firsthand and authored the historical book *Martin Guitars: A History*. It can be said that he fulfilled the role of a “historian” by reclaiming the craftsmanship of specific top-of-the-line models and properly preserving and passing on the legacy of the past.
On the other hand, Ren Ferguson did not limit himself to reissuing specific models; he took on the role of general supervisor to rebuild not only the factory but the Gibson Acoustic brand itself, which was suffering from declining quality and stagnation at the time.From reviewing blueprints to internal structures (bracing), finishes, and quality control, he rebuilt the entire brand from the ground up. While respecting history, he was a “practical craftsman” who constantly created new structures and designs on the shop floor.
■ History Woven by His Hands Even Today
And what we at Advance Guitars most want to convey to you is the difference in how they “preserve and pass on their craftsmanship.”
Mike Longworth deeply researched Martin’s history and left his vast knowledge and achievements for the world in the form of a “book.”
On the other hand, Ren Ferguson continues to build guitars right this very moment.
Now that he has stepped away from the massive Gibson brand, he has returned to his roots at “Ren Ferguson Company.” Together with his family, he enters the workshop, shapes the wood, and applies inlays. Rather than simply preserving skills and knowledge in books or data, he is actively engaged in the “direct transmission of craftsmanship and spirit” by literally working side-by-side in the same space.
While respecting the history of the past, he never stops moving forward, continuing to build new guitars with his own hands alongside his family.
I believe that this very approach represents one of the purest and most beautiful ways to be a craftsman.
An example of a past work by Ren Ferguson
〜 Artists 〜
If you want to convey his “true greatness” to those unfamiliar with him, the quickest way is to look at the famous artists associated with him.
■ John Lennon
It was Ren Ferguson who was entrusted with the task of creating a tribute guitar for John Lennon at the Gibson Acoustic factory, following a direct invitation from Yoko Ono herself. He visited the Rock and Roll Hall of Fame, retrieved John’s beloved instrument (the J-160E) from the exhibition, and conducted a thorough analysis of everything from the instrument’s condition to the artwork John had painted on it. The result was a “trio”—a set of three guitars tracing the evolution of a single instrument. The first guitar is a reproduction of the illustration drawn during the “Bed-In” peace protest (featuring Ren’s own initials hidden among John’s drawings).The second is a vivid psychedelic model featuring blue and purple tones with hand-painted orange lines. The third is an early standard-spec model from before John stripped the finish and applied his own paint. As a testament to this great project, Yoko Ono brought one of the guitars back to Japan and donated it to the “John Lennon Museum.”
■ Paul McCartney
An original guitar belonging to Paul McCartney, who created numerous Beatles classics, including the hit "Yesterday." Len crafted a special guitar that perfectly recreated its mid-1960s specifications. This guitar, which even replicated the scratches (aged finish) exactly as they appeared on Paul’s own instrument, was later signed by Paul himself and sold at a charity auction for an astronomical sum.
■ Ron Wood (The Rolling Stones)
We have also received a direct commission from Ron Wood, a living legend of the rock world. In response to Ron’s request for “something like a flame,” Ren crafted an artistic instrument (SJ-200) featuring a burning flame inlay on the fingerboard made from abalone and mother-of-pearl, along with a hand-carved pickguard.
■ Johnny Depp
While watching the movie *Pirates of the Caribbean*, Ren was inspired by the line “A ship is freedom” and thought, “A guitar, too, is freedom itself—it can take you anywhere.” He then crafted a pirate-themed guitar. It is said that when Johnny Depp received this guitar at a film studio in California, he never even strummed a single string; instead, he simply sat on a curb and silently gazed at its incredible details and ornamentation for a full two hours. Needless to say, he grew to deeply love that guitar—so much so that even film producer Jerry Bruckheimer placed an additional order, asking, “Make me one just like it.”
Thus, behind the countless classic songs and historical cultural moments we have come to know, there lies the deep bond of trust between the guitars he crafted and the top stars. Furthermore, many of the world’s leading guitar luthiers today honed their skills under his tutelage. He is truly the “Master of Masters” reigning at the pinnacle of the industry.
~ Builders ~
Furthermore, numerous renowned builders currently active on the world’s front lines—such as John Walker and Kevin Kopp—learned their craft under him before striking out on their own.
He is truly a figure who deserves to be called the “Master of Masters.”
〜Works〜
The guitars he creates go far beyond the boundaries of mere musical instruments.
His signature intricate and dazzling inlay work, and his uncompromising selection of woods based on both acoustic properties and visual appeal.
Combined with his exceptional vision for constructing the most beautiful guitar structures and world-class technical skills to bring them to life perfectly,
The works born from this fusion can truly be called works of art.
In fact, the flagship models he crafted during his time at Gibson are now extremely rare to find,
and continue to increase in value as supreme collector’s items that owners refuse to part with.
The story between us at Advance Guitars and Ren Ferguson
began when our shop acquired the exquisite J-200 collection he crafted in the 1990s.
*For details on how this came about, please refer to the column below.
To be honest, I myself had always held a certain image of him as a “former heavyweight from a major manufacturer.” However, as I exchanged words with him personally and came into contact with the instruments he is currently crafting, I was keenly made aware that introducing him solely through the lens of his past brand would be woefully inadequate.
He has now launched his own brand, "Ren Ferguson Co.," and crafts guitars alongside his family.
While he was with the manufacturer, he created masterpieces within the “constraints” of cost, production efficiency, and brand tradition.
But now, he has been freed from all constraints.
His experience, his sensibility, and his pure passion for “making what he wants, the way he wants.” The sheer brilliance of the guitars into which all of this has been poured may no longer even need to be described in words.
Just by touching it, you’ll understand everything.

-1946
Born in Detroit, Michigan
-1961
Like many others, Ren began playing the guitar with his older brother and friends.
-1962
During high school, Len was so fascinated by F-style mandolins and ornately carved banjos that he decided to build a “bluegrass banjo” for his younger brother in the school’s woodshop.
Around that time, he began working at “Westchester Music” near Los Angeles International Airport. Many instruments damaged during air transport were brought there for repair estimates. Len was allowed to purchase some of these damaged instruments, which became the starting point of his career as a repair technician.
- Circa 1965–1967
While working as a sales representative for the West Coast region at Dobro Guitars (Original Musical Instrument Company, OMI), he also created custom inlays.
-1967–1969
Ren enlisted in the Navy and was assigned to a repair ship docked in Yokosuka, Japan.
There, he mastered advanced machining techniques.
-1969
After leaving the military, he joined Westwood Music in Los Angeles, where he worked in sales and repairs.
-1970
In Santa Monica, California, he launched a stringed instrument repair business with Rob Erlas.
-1971
Len moved to Venice Beach, California, and began building banjos.
He also established a small guitar workshop called “Ren Ferguson Company” with several apprentices.
-1976
The company closed its workshop, and he moved to Colorado.
-1979
Ren moved to Big Timber, Montana, with his wife, Lenny, and began life as a trapper.
-1983–
He secured a position as a stockmaker at Shiloh Sharps and produced his first 1,000 rifles. The company’s owner, Wolfgang Droge, was a skilled machinist and tool designer.
While sharing his expertise with Ren, he encouraged Ren to design jigs to improve the precision of manufacturing and assembly.
-June 1985–
At Flatiron Mandolin, he was involved in mandolin manufacturing as a product manager and designer.
-February 1987
Flat Iron Mandolin was acquired by Gibson and began supplying instruments as an OEM partner.
-March 1989
I began designing jigs for the new factory and built prototype guitars for testing.
-1996–
As a Gibson Master Builder, he oversaw warranty services, custom designs, and tooling design.
I have developed unique, elite instruments, including the "Custom Line" and reissues of all "Historic Line" guitars.
-December 2011
I left Gibson. The Custom Shop had shifted most of its manufacturing to the Gibson factory floor.With the collaboration of Val Boliso and Jason Jones, it was no longer permissible to independently craft one-of-a-kind guitars. Furthermore, immediately after returning from a trip to Japan (in October), he was injured while hunting, sustaining an injury that required three months to heal. At the age of 66, he decided that he might have the chance to work from home again (retirement).
-January 2012
After leaving Gibson, he attempted to retire temporarily, but Larry Thomas, then president of Fender, contacted Ren and asked him to further refine Guild products.Ren accepted this offer and became Chief Engineer of Fender’s Acoustic Division. He continued to play a wide-ranging role at both the Guild factory in New Hartford, Connecticut, and the Fender factory in Ensenada, Mexico, working on instrument design, manufacturing process improvements, and the design of decorative parts and models. He also created signature models for Guild, which was a subsidiary of Fender at the time.
At that time, a venture capital group acquired Fender. It was decided to sell the "Guild" brand and close the New Hartford factory.
-July 2014
The new owners of Cordoba/Guild approached Ren with the task of building a new factory in Oxnard, California. Ren moved to California with his wife, Lenny, and son, Timothy, and began the process of setting up the new factory.
-January 2017
He was hired as a consultant for Shadow Electronics, a Chinese company planning to open a state-of-the-art acoustic guitar manufacturing plant.
-2019–
He revived his own brand, “Ren Ferguson Company (Ren Ferguson Co.).”
Together with his children, Virginia and Timothy, he is dedicated to crafting custom models that bring together the creativity and passion he has cultivated over many years.
"A guitar should not be merely a piece of art to be displayed. It must be 'Functional Art'—something that instinctively draws the player in and makes them want to play."
Three special guitars crafted exclusively for Advance Guitars
And so, the story began.
The setting was the 2024 NAMM Show, followed by a private dinner with him and his family.
There, we deeply shared our mutual love for guitars and our philosophies on craftsmanship.
In that conversation, the words we entrusted to him were a simple yet ultimate request.
“Please push Ren Ferguson to his absolute limits.”
He accepted our request and promised to craft three special guitars exclusively for Advance Guitars.
It took about two years from then until completion. A project that took time and to which he devoted all his energy.
The result is the custom model created through the “Ren Ferguson × Advance Guitars Signature Lineup ” collaboration.
The request we entrusted to him was extremely simple, yet it demonstrated our complete trust in him.
It was: “Rather than focusing on a single specific shape (such as the Super Jumbo), use a variety of other shapes, and leave everything else entirely up to your free imagination and inspiration, Ren.”
This reflected our strong desire at Advance Guitars: “We want Japanese players to actually hold the wide variety of guitar shapes created by Ren Ferguson in their hands and experience their immeasurable appeal firsthand.”
With all constraints removed, he selected the woods and shapes guided solely by his career and passion. The result is the following three guitars.
Each is a genuine one-off model—the only one of its kind in the world.
Introducing Advance Guitars Custom Models
- Mahogany Early Slope Shoulder
- Flame Claro Walnut
- Flame Maple Early 985
Advance Guitars Signature
"Mahogany Early Slope Shoulder"
The defining feature of this model is the exquisite mahogany used for the back and sides, which is so beautifully balanced and uniform that one is tempted to describe it as "creamy." Its subdued, warm hue and smooth grain exude a profound aura reminiscent of a "pre-war vintage guitar" that has weathered the test of time.
The body shape features the classic "Early Slope Shoulder" design, which Ren Ferguson has perfected over his long career.The hand-carved, smoothly finished ebony bridge, the unique red, blue, and yellow marquetry that beautifully adorns the body’s edges, and the intricate inlays extending from the headstock to the fingerboard all lend an artistic elegance to the traditional style.
In terms of sound, mahogany is characterized by a rich, warm midrange and a clear, woody tone. The combination of this premium mahogany, the deep body of the sloped shoulders, and the moderate tension unique to the short scale results in a response that is surprisingly rich and gentle to the player’s touch.
Thanks to the bracing voicing, hand-tuned to perfection, this instrument—though a New—already possesses the matured nuances of a vintage guitar, producing a rich, full-bodied sound with a strong core. This is a guitar worthy of being called the pinnacle of the standard, a feat achievable only by a master who knows the classic mahogany sound inside and out.

Advance Guitars Signature
"Flame Claro Walnut Dreadnought"
When I saw the flame Claro walnut used for the back of this dreadnought, I felt the same vitality as that of the 3,000-year-old giant camphor tree I saw in Kyushu.
The abalone inlays on the headstock and the unique marquetry—a harmonious blend of red, blue, and yellow—lend a sense of elegance to its rugged yet beautiful natural form.
While walnut is generally considered to have tight acoustic characteristics, the sound of this particular instrument resonates with a sweet, rich tone reminiscent of rosewood. Furthermore, it lacks the harshness often associated with rosewood, featuring a very smooth and mellow sound that is easy on the ears.
Of the three guitars crafted this time, this is undoubtedly the model with the “richest sonic detail.” The combination of a 25.5-inch long scale and a dreadnought body allows the mid-low range harmonics to swell richly, creating a deep sustain unlike anything experienced before—as if the sound were swirling within the body’s resonance chamber.

"I still treasure and use the tools I received from Japanese craftsmen."
Advance Guitars Signature
"Flame Maple 985"
This guitar stands out for its dazzlingly beautiful, top-quality flame maple used for the body sides and back. The intricate, three-dimensional flame grain, which changes its appearance depending on the angle of the light, is truly a work of art created by nature.
This model features the "985" body shape—Ren Ferguson's own original design, a unique evolution of the J-185 style—which is Recruit.The beautifully curved, hand-carved ebony bridge, the unique marquetry adorning the body’s edges, and the inlay shining on the headstock add exquisite accents to the maple’s white, translucent grain.
In terms of sound, maple is generally characterized by its “hardness, excellent sound separation, and clear tone.” However, the combination of the exquisitely curved “985” shape and Ren’s exceptional voicing techniques brings out not just hardness, but the rich warmth inherent to acoustic guitars.
A fresh, bright sound where the contours of each note stand out clearly, yet never strain the ears. Its clear resonance, which cuts through an ensemble without getting lost, faithfully conveys every subtle touch and nuance of the player, resulting in a finish that truly embodies “functional art.”

A privilege reserved only for the owner
As for the beauty of the design, the photos speak for themselves. However, what surprised me most about these guitars was their "sound."
Despite being a New, it simultaneously possesses the aged nuances of a vintage guitar and the rich harmonics of a modern instrument.
I wonder how this guitar will develop as it is played over time.
Even I cannot experience that process of change.
It is a privilege beyond compare, one that only the owner who holds this guitar in their hands can experience.
To be honest, I’m incredibly envious.
Although Ren Ferguson Co. guitars are newly crafted modern instruments, they already possess a “collectible” quality.
Each one is a one-off, and there’s no telling when the next one will become available. It exists nowhere else in the world. And we must not forget that each instrument is imbued with his career and life spanning over half a century.
This isn’t a phrase I often use when describing a New guitar, but let me say it anyway.
Ren Ferguson Co. guitars are both “the ultimate performance instruments” and, at the same time, “the ultimate collector’s items.”

He maintains strong connections with collectors and dealers overseas. Guided by the belief that “the history of a guitar can change with a single color or stamp,” he strives to provide detailed and passionate commentary.
A Note: This is the long-awaited new guitar by Ren Ferguson. We have been in communication with him for several years leading up to this. I have written this description carefully to convey its appeal, but you cannot truly experience this sense of wonder until you hold the actual instrument in your hands. It is undoubtedly one of the finest guitars of our time. Please look forward to future updates as well.
