His amps fetch eye-popping sums, and the stories are legendary. Dumble’s friends share their memories of a true musical visionary.
Howard “Alexander” Dumble was about as close to a guitar mystic as you can get. He was an eccentric recluse as well known for the mythology surrounding his creations as for the amplifiers themselves. The list of players who have relied on his amps carves a through line of the history of modern electric guitar styles. Eric Clapton, Carlos Santana, Stevie Ray Vaughan, Jackson Browne, Robben Ford, Eric Johnson, John Mayer, Sonny Landreth, Joe Bonamassa, and dozens of other A-listers found their sound through a Dumble amp. On January 17th, Dumble passed away at his home in Turlock, California.
Not many people really knew Dumble on a close personal level. Considering his aversion to interviews and media, he could have probably passed through any Guitar Center relatively unnoticed. But Larry Thomas, former CEO of Fender and Guitar Center,was a close friend. “The definition of a genius is someone who knows more about a subject than anyone else. His genius was being able to turn what he heard in your playing into an amp that made it better.” And that skill goes far beyond the schematic.
Kenny Wayne Shepherd remembers when he brought an amp to the workshop for repair: “After popping open the circuit he would jump around with a multimeter and would almost instantly know how to fix it. There are probably other amp techs that would understand those readings, but Dumble was the only one in the world who knew what those readings should be.”
“I think his greatest satisfaction came from creating technology that translated into art by the individual artists he specifically tweaked his designs for.” – Sonny Landreth
In the mid 1960s, while still a teenager, Dumble got a job designing amps for Mosrite. Semie Moseley was impressed by the talented youngster and proposed a partnership. “He offered to go in with me to build 10 amplifiers. He bought the parts and paid me $90 a week—for about four weeks, and then I had to work for free,” Dumble told Guitar Player in a 1985 interview. The Ventures were one of Mosrite’s biggest endorsees and caught wind of the new amps but declined to use them. Dumble said, “It was a little too much rock for them.” These piggyback amps might be the rarest Dumble creations of all and it’s believed that only one or two are still in existence. In the late-’60s, a lengthy tour playing bass for Canadian singer/songwriter Buffy Sainte-Marie (who was unaware at the time of his talent for creating amps) helped Dumble open his first workshop.
There was an ad-hoc audition process if a player wanted to commission a Dumble amplifier. In order to even get the opportunity to meet with the builder, a player would need a recommendation from someone in Dumble’s trusted circle. Then, if they were invited, the audition could be simply playing for him during a casual hang, or he might ask for a CD. “Alexander really only wanted to make amplifiers for the very best players in the world,” says Thomas. It didn’t seem like fame was a deciding factor either—Dumble would turn down requests from big-name players. “He treated his amps like they were his children,” says Bruce Forman. Back in 2019, Forman brought Dumble a 1966 Fender Vibrolux for his two most popular mods: RockFonicks and Ultra-Phonix. “He wanted them out there making music.”
Each amp Dumble created was carefully and painstakingly crafted to accentuate the best parts of the owner’s style.

Many times, the only real proof that an amp had been “Dumble-ized” would be a handwritten tag written by the man himself.
Those lucky enough to pass the “audition” and spend time with Dumble would often comment on his amazing touch on the instrument. During one of his visits to Dumble’s shop, Shepherd found himself on the receiving end of a subtle guitar lesson. “He would always ask permission to show me stuff,” remembers Shepherd. These gentle “lessons” would inevitably lead to impromptu jam sessions—some of which Shepherd recorded for his own benefit. “If I didn’t record those licks he showed me, I would have forgotten them 30 minutes later.”
The one guitarist who’s most synonymous with the sound of a Dumble is Robben Ford. For nearly 40 years, Ford has been the caretaker of an Overdrive Special that, in his hands, has become the benchmark for classic Dumble tones. His latest live album, Live at Yoshi’s ’96, became an unintentional tribute—not only are the tones visceral and huge, but the cover features a plain image of the most famous Overdrive Special around. Ford purchased the head for $1,200 when Dumble was set up at The Alley in North Hollywood. “Alexander told me that watching me play my early ’60s Fender Bassman inspired him to create the Overdrive Special,” remembers Ford. With the rise of Ford’s career in the ’80s and ’90s, word began to spread about Dumble’s builds—and his eccentricity. “One of the final tests Dumble would do on amps would be to remove the tubes and drop it out of a three-story window. If it worked after that he knew it was finished,” mentions Ford.
“He was a mystery, to all of us.”– Robben Ford
About 10 years after obtaining the first Overdrive Special, Ford put in an order for another one to keep in Europe. Originally, this was going to be a 50-watt model because Ford was looking for ways to keep the stage volume down, but that didn’t last long. “Turns out I was addicted to 100 watts in a live situation,” says Ford. “How do you get headroom and tone? Dumble.” Several years ago, Ford was going through a divorce, moving to Nashville, and was looking to sell the second ODS. Knowing Dumble’s general dislike of the secondhand market for his amps, Ford reached out and brought up the idea, offering to split the proceeds. “He made this amp. I’m just the salesman,” said Ford. After agreeing to a 60/40 split, Dumble connected Ford with a buyer, who would occasionally help Dumble acquire components for his builds. “Dumble told me not to send a check and just have his cut be a ‘credit’ with the new owner. He was a mystery, to all of us.”
His off-the-grid lifestyle forced Dumble to frequently look at alternate payment arrangements with clients. One of the early users of his amps was singer/songwriter Christopher Cross, who was brought in by Bonnie Raitt. Cross and Dumble decided on two KT88-loaded heads (a first for Dumble at the time) with matching 2x12 cabinets in orange suede for a clean sound and an Overdrive Special with a 4x12 cab for a lead sound. Naturally, Cross needed a way to switch between sounds easily. The solution was based around a pair of Japan-made Strats that were modified by Valley Arts. Each guitar only had a middle and bridge pickup and was outfitted with a heavy-duty switch—imagine the massive switches on the back of vintage Fender amps. An oversized cord went to a blue two-space rack unit that housed mechanical relays to control which amp was engaged. “I really couldn’t afford to mess around with pedals at that time,” says Cross. At the time, Dumble was living in a house owned by Jackson Browne and Cross headed up there to pay for the custom relay box. “When I asked him what I owed him, he handed me a torn-out page from a Sears catalog,” recalls Cross. Dumble had circled a washer and dryer unit and told Cross that if he bought those for him, they were square.
Ben Harper pulls no punches when it comes to his amps. This one was the eighth Dumble ever made! He got it from one of his early mentors, David Lindley. The head runs into two 12" Celestion speakers, one housed in a tweed Glasswerks cab and the other is in the green Dumble combo.
Along with the tweed Twins, Joe Bonamassa runs a pair of Dumble Overdrive Special combos. This silverface model was built in 1980 and has been retrofitted with Bonamassa’s signtuare Celestion 85-watt speaker. This one is 50-watts, which Joe Bonamassa prefers over their 100-watt big brothers.
Several companies tried to partner with Dumble to bring his amps to a larger market. “He created an entire industry that he didn’t participate in. Alexander never cashed in on that. He steadfastly had a code of conduct he lived by until the very end,” says Joe Bonamassa, who currently has a stash of four Overdrive Specials and a Fender Vibrolux with the UltraPhonix mod in his collection. According to Bonamassa, Dumble is “by far the most innovative circuit designer of all time,” and he attributes the boutique amp boom to Dumble’s work.
Probably the closest Dumble ever got to working with a larger company was when Thomas pitched the idea of Fender licensing one of his designs. The two had a lot in common and shared a deep love for Leo Fender and his designs. Early discussions revolved around doing a Dumble-approved modded Twin or Deluxe Reverb. Thomas also mentions that pedals were also a possibility. “I have a few of the [amp] prototypes,” says Thomas. “Simply put, one roadblock was we couldn’t really figure out how to pay him.” After spending a few years on the project, it ran out of steam. Thomas last saw Dumble in October when they met for dinner the night before he moved to Turlock. “He was in a really good space,” says Thomas.
“His amps were superheroes.” – Henry Kaiser
“His wish was that once he was gone there would be no more Dumble amplifiers,” says Ford. “Most people want to leave behind a legacy, but he didn’t want that.” Health issues prevented Dumble from doing much work over the last six months of his life, but a few projects really excited him. Slash had recently connected with him for a build, and he was in talks to make an amp for Keith Richards.
During our talk, Larry Thomas held up a framed turret board populated with the components of an old Fender 5E3 Deluxe circuit. It was a Christmas gift from his friend, Alexander Dumble. The solder joints were impeccable. Around back was an inscription describing how the Tru-Ohm resistors and Allen-Bradley capacitors had been carefully harvested from older amplifiers. Dumble’s handwriting—even carved in the back of a frame—is unmistakable. It was a work of art that he made for his friend celebrating their shared love of a particular old amp.
Alexander Dumble’s contributions—both direct and indirect—will stand alongside names like Leo Fender and Jim Marshall. For years to come his designs will be analyzed, discussed, and copied, much like his heroes. Even though many will never get past the market price for his creations, Dumble might have said it best back in ’85, “There are hundreds, perhaps thousands or millions, of valid guitar tones. When the air becomes electric, that’s the right sound, no matter what the one is.”

Nashville session and stage MVPs craft an aural wonderland with their genre-defying instrumental album, In Stereo.
Working from a shared language of elegance and grit, Nashville guitar domos Tom Bukovac and Guthrie Trapp have crafted In Stereo, an album that celebrates the transcendent power of instrumental music—its ability to transport listeners and to convey complex emotions without words.
In Stereo also honors Trapp and Bukovac’s friendship, which ignited when Trapp and Bukovac met over a decade ago at Nashville’s 12 South Taproom eatery and club—an after-hours musician’s hangout at the time. They also sometimes played casually at Bukovac’s now-gone used instrument shop, but when they’re onstage today—say at Trapp’s Monday night residency at Nashville’s Underdog, or at a special event like Billy Gibbons’ BMI Troubadour Award ceremony last year—their chemistry is obvious and combustible.
“Guthrie is very unpredictable, but for some reason our two styles seem to mix well.”—Tom Bukovac
“It’s like dancing with somebody,” Bukovac says about their creative partnership. “It is very easy and complementary. Guthrie is very unpredictable, but for some reason our two styles seem to mix well, although we play very differently.”
As Pepé Le Pew probably said, “Vive la différence.” While they’re both important figures in Nashville’s guitar culture as badass, in-demand session and live players, Trapp also points out that the foundation of their respective careers is on opposite swings of that pendulum. Bukovac’s reputation was built on his studio work. Besides his touring history, he’s played on over 1,200 albums including recordings by the Black Keys, Glen Campbell, Keith Urban, Stevie Nicks, Bob Seger, and Hermanos Gutiérrez. And Trapp considers himself mostly a stage guitarist. He emerged as a member of the Don Kelly Band, which has been a Lower Broadway proving ground for a host of Nashville 6-string hotshots, including Brent Mason, Johnny Hiland, and Redd Volkaert. In recent years, you may have seen him on the road with John Oates. It’s also possible you’ve heard Trapp on recordings by Rodney Crowell, Emmylou Harris, and Roseanne Cash, among others.But back to In Stereo. “This record is truly for the love of music and not giving a shit what anybody else is going to think about it,” relates Trapp, as he, Bukovac, and I sit and talk, and they noodle unplugged on a Danocaster and an ES-355, respectively, in the warm, instrument-filled surroundings of the Cabin Studio in East Nashville. The album was recorded there and at another studio, simply called the Studio, with Brandon Bell engineering.
“When we started working on the album, it was very loose,” explains Bukovac. “I never wanted to bring in anything that was complete because the key is collaboration. So, I knew better than to come in with a complete song. And Guthrie didn’t do that either. We would just come in with a riff for an idea and then let the other guy finish it—and that’s the best way to do it.”
“It’s got enough humanity—real playing—mixed with the cinematic side of it.”—Tom BukovacAll of which helped make In Stereo’s 11 compositions seamless and diverse. The album opens with a minute-long ambient piece called “Where’s the Bluegrass Band,” which blends acoustic and electric guitars, feedback, and keyboards with generous delay and reverb—telegraphing that listeners should expect the unexpected. Of course, if you’ve been following their careers, including their estimable YouTube presence, you’re already expecting that, too. So, a soulful composition like “The Black Cloud,” which builds from a Beatles-esque melody to a muscular and emotive power ballad of sorts, comes as no surprise. “Desert Man” is more of a mindblower, with its dark-shaded tones and haunting melodies. “Cascade Park” is an unpredictable journey that begins with delay-drenched piano and leads to Trapp’s acoustic guitar, which evolves from contemplative melody to feral soloing. And “Bad Cat Serenade” and “Transition Logo Blues” balance the worlds of country and jazz fusion. Overall, the music is timeless, emotional, and exploratory, creating its own world, much as Ennio Morricone did with his classic film soundtracks.

“It’s a lot to ask somebody to sit and listen to an instrumental record,” Bukovac offers, “so I was just trying to make sure—and I know Guthrie did the same—it doesn’t get boring. When I finally sat and listened to this thing in its entirety, which was many months after we actually recorded, I had forgotten what we’d even done. I was overwhelmed. I love that I never got bored. It moves along and has moments where it gets into sort of a trance, in a good way, but it never stays there too long. It’s got enough humanity—real playing—mixed with the cinematic side of it.”
Trapp picks up the thread: “If you’re in Nashville for a long time and you’re paying attention at all, you understand this is a song town. No matter how you slice it, it’s all about the vocal and the lyric and the song. So, it doesn’t matter if you’re making an avant-garde instrumental guitar record. That influence is pounded in your brain—how important it is to trim the fat and get down to the song. A song is a song. It doesn't matter if it’s instrumental or not. It’s a ‘Don’t get bogged down and get to the chorus’ kind of thing.”
“A song is a song. It doesn’t matter if it’s instrumental or not. It’s a ‘Don’t get bogged down and get to the chorus’ kind of thing.”—Guthrie Trapp
Which alludes to the sense of movement in all these compositions. “It’s very important that every section of a song delivers every transition,” Bukovac adds. “When you go into a new room, when you open that door, it’s got to be right. That’s what I think about records. And there’s a lot of shifting on this record. We go from one field to another, and were very concerned about making sure that each transition delivers.”

That kind of thoughtful development—the set up and delivery of various compositional sections in songs—isn’t exactly a lost art, but it’s certainly rarer than in earlier decades. Listen to Elton John’s Goodbye Yellow Brick Road to hear how Davey Johnstone sets up verses, choruses, and bridges—or anything by David Gilmour—for reference. It’s also a goal best accomplished with a team of exceptional players, and, of course, Trapp and Bukovac enlisted some of Music City’s finest. The cast includes steel-guitar legend Paul Franklin, keyboardist Tim Lauer, bassists Steve Mackey and Jacob Lowery, and drummers Jordan Perlson and Lester Estelle.
“Don’t tell my mom, because of course we all want to make a living, but playing music that has integrity is at the top for me.”—Guthrie Trapp
“We recorded the basics—really, most of the tracks—live on the floor,” says Trapp.
“We kept a lot of the original throw-down/go-down solos,” Bukovac adds. “There were very few fixes and overdubs. One of the best moves we made was letting an outside person objectively sequence it, because you can get a little bit too inside your own thing. It’s like … if you’ve ever done a photo shoot, if you let somebody else choose the photo, it’s never going to be the one you’d choose, and it’s probably a better choice.” That task fell to Nick Govrik, another friend and engineer.
The terrain Bukovac and Trapp cover on their first album together is expansive and transporting—and packed with impressive melodies and guitar sounds.
The shipment of In Stereo’s vinyl arrived shortly before Trapp, Bukovac, and I talked, and while Bukovac released his first solo album, Plexi Soul, in 2021, and Trapp put out his releases Pick Peace and Life After Dark in 2012 and 2018, respectively, they seemed as excited to listen to it as teenagers in a garage band unveiling their debut single. That’s because, despite their standing and successes, playing guitar and making music is truly in their blood. What they play is a genuine expression of who they are, ripped from their DNA and presented to the world.
“Don’t tell my mom this, because of course we all want to make a living, but playing music that has integrity is at the top for me,” says Trapp. “These days, with AI and people worried or insecure about where the music business is going, and all these Instagram players who just are fixing everything with Pro Tools so they sound like they’re in a studio, I don’t worry because we’re not selling bullshit. We have 35 years of real experience between us, and when we do social media, we’re just reaching for a cell phone and posting it. It’s organic. That, to me, is a big difference. At the end of the day, I can sleep well knowing that I have earned the respect of the people that I respect the most. It’s just authentic music made for the very reason we got into this in the first place. We love it.”
