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.”
Dumble Amps: 10 Guitarists on the Late Legend’s Designs
This month's jams include Code Orange, Sonny Landreth, Big Thief, Devon Gilfillian, and more!
The Louisiana slide legend finds inspiration in standard fretting and the whammy bar on Blacktop Run, an acoustic/electric mashup of roots styles and rad techniques.
There is a contingent of players who came up in the 1970s and ’80s that many see as setting the standard for contemporary electric guitar. Informed by the jazz masters, Jimi Hendrix, the ’70s L.A. studio scene, and a shared love of blues, they possess immaculate phrasing, fearless experimentation, deep songwriting chops, and to-die-for tone.
Among these A-list 6-stringers are such icons as Larry Carlton, Robben Ford, Eric Johnson, and John Scofield. But there’s one player in this group who, with a slide on his pinky finger, a Strat plugged into a Dumble, and Cajun culture in his veins, carved out a singular sound all his own. That is southern Louisiana’s Sonny Landreth.
Landreth hit the scene in the ’80s as a session ace, creating a resume that includes work with John Hiatt, Jimmy Buffett, Mark Knopfler, and John Mayall’s Bluesbreakers. And it wasn’t long before his unique slide guitar style and string of solo albums catapulted him to the upper ranks of guitar heroes. Vince Gill and Eric Clapton regularly sing the man’s praises, with Clapton calling him, “One of the most advanced guitarists in the world.”
Part of what has kept Landreth at the top is his willingness to take chances and push his signature style in bold and new directions. From all-instrumental albums to half-acoustic/half-electric live recordings, and occasional all-blues releases, he’s open to following his muse.
“Slide is adaptable to any style of music,” says Landreth. “I think that’s really important because, if I can keep it interesting for me, then I feel pretty good.”
Landreth’s drive to stay inspired has never been more apparent than on his newest release, Blacktop Run. The album showcases his versatility, and with the help of his most trusted musical compatriots, he brings all the best elements of his past into a single recorded set.
From the title track’s opening resonator salvo, Landreth’s impeccable skill, tone, and songwriting are on full display. But just as you settle into the song’s Southern groove, here comes the high-energy and all-instrumental second track, “Lover Dance with Me.” In fact, Blacktop Run is rife with new sounds and techniques, from swapping slide for a Strat’s whammy bar to foregoing a guitar solo altogether on the album’s closing number.
“As I got started using those new techniques, I started writing songs, and one thing rolled into the other,” he says. “Like on ‘Something Grand,’ I thought it was much more intimate with the acoustic creating the underlying vibe of the song, and then we built on that.”
Landreth’s inspiration struck at the right time. With Derek Trucks and a new breed of electric slide players like Joey Landreth (no relation) and Ariel Posen on the rise and crediting Sonny’s influence, Blacktop Run is the perfect way to encapsulate his stellar career.
We caught up with Landreth to discuss his new album as he was packing for a performance that night. He talked about making Blacktop Run, the gear he used to elicit his awe-inspiring tones, and why he confidently says the state of slide guitar is “as things should be.”
Blacktop Run is your first studio album of mostly original music in a while. What inspired this eclectic record?
All that’s come before, in a way, laid the groundwork. I was able to imagine some songs as acoustic, some electric, some as a combination of the two. Then, there are songs with vocals and others that were instrumentals. In a way, it’s a combination of combinations [laughs].
I also brought back my old producer [R.S.] Bobby Field. We hadn’t worked together for so long. He’s so brilliant and so much fun to work with. He and I met back in 1990. He had called me to play on the John Mayall album A Sense of Place. Then he was my producer on my albums, Outward Bound [1992] and South of I-10 [1995].
How did you track the album?
We did a little bit of everything. Typically, I’ll start at home to jumpstart the whole process. I’ll put down a guitar track or two to get the vibe. Maybe, if it’s an instrumental, I’ll develop it a little bit more. Then I’ll go to my engineer Tony Daigle’s studio [Electric Comoland, in Lafayette, Louisiana] to finish those ideas up. That way, I can go ahead and have the guitar done, sing the verses, and take those tracks into the studio. Then I’ll have the guys [bassist David Ranson, drummer Brian Brignac, and keyboardist Steve Conn] come in and lay down their parts live.
TIDBIT: Landreth starts albums by cutting guitar parts at home. He then takes them to Electric Comoland—a studio owned by his longtime collaborator, Grammy-winning engineer Tony Daigle—to polish before his band tracks the final recorded arrangements.
Blacktop Run covers a lot of stylistic ground. How does it differ from your previous work?
I think the heart of it is a rootsier feel on some songs, while others are going in a more instrumental direction. The acoustic and electric give different types of grooves. I think it’s more of an electric album, but it was nice to get back to some more real-deal ballads like “Something Grand,” which is one of my favorite pieces. For me, building an atmosphere with a track is one of the best, most rewarding things.
Another way it’s different is that some of the songs are by Steve Conn, my keyboardist and buddy. He’s played on just about all of my records, and he’s a great writer. I’ve played both of those songs with him over the years: “Somebody Gotta Make a Move” and “Don’t Ask Me.” I always loved them.
On “Beyond Borders,” doesn’t Steve play a part that was written for Carlos Santana?
Yes. That was for the guest album, [2008’s] From the Reach, where I wrote songs for guest artists to play on. And that was a bit of a gamble. “What if they say no?” Well, that’s what happened. We cut all the tracks in the studio, and we sent that to Carlos. It apparently wasn’t a good time for him, for whatever reason.
But it was cool to revisit that song. Man, it’s got so much energy, and it’s very different. It’s got a lot of different changes and different colors. So I asked Steve, “What would you think about playing Wurly on it, instead of Carlos?” He thought that was pretty funny. Actually, I think it gave it more of a contrast between the guitar and the keyboards, making it really interesting. It gave each section of the song its own voice.
You mentioned “Something Grand” is one of your favorites. But there’s no guitar solo on that song. That might upset a few Sonny Landreth fans.
Well, I didn’t set up to go, “Okay, this would be a song without a guitar solo.” But when I got through with all the parts, it was really obvious to me that it didn’t need it. Sure, I could have put one on there, but I was so sensitive to every aspect that went into creating that atmosphere that a big guitar solo would have taken away from the interplay.I think it’s interesting that the piece that I care so much about, it’s the only one I never played a solo for. It’s cool.
For “Lover Dance with Me,” what about that song inspired you to put down the slide?
Back in 2018, John Hiatt called me and he pointed out that it would be 30 years from the time we recorded his album Slow Turning. So we decided to do a 30th-anniversary tour. The only thing was, back in the days of playing with him, I was playing half the songs without the slide. That’s how I used to operate in the days of being in a road band. I hadn’t played like that in 13 years! [Laughs.]
Now, not only did I have to remember how I played those songs, but I had to get my chops back together without the slide. And I got to tell you, man, that is a strange feeling. It was quite the experience, trying to whip that into shape.

It’s fascinating, players around the world are trying to learn your slide technique. And here you are saying that playing a standard-tuned guitar without a slide was a challenge.
I know, man. Truth be what truth is. Here’s the thing: I still use the fingers on my left hand when playing slide. But the positioning of the way that I do it with slide is very different, especially with the first finger. Without a slide, doing double-stops or using it to barre a chord, boy, that’s … [sighs].
But the cool thing that came out of it was I started hearing all these melody ideas, riffs, and chord melodies. As I was learning and working on the Hiatt songs, I got these ideas, and it started to flow. I started putting the ideas down for a standard guitar. Now I’ve got so many, I’m aiming toward a whole album like that.
Another thing that happened is, I started experimenting with the whammy bar. In the past, I played around here and there, but nothing serious. But then I realized that I could take some of the right-hand techniques from the slide and apply that to the trem bar. That got me fired up, and “Lover Dance with Me” came from one of those ideas.
It’s an entirely different technique, and yet it still sounds like Sonny Landreth.
Well, one would hope [laughs]. If there’s one thing I’ve learned, you have to have the antenna up for when new inspiration happens. You have to recognize it and act on it.
You are as famous for your tone as your playing. And one of my favorite tones on the album is the fuzz lead on “Groovy Goddess.” What did you use to get that?
Man, that’s a classic fuzz sound. The one I use on the road is the Demeter Fuzzulator, because it’s like a high-end version of fuzz. I can play chords and do a lot of different things. But for that song, I wanted more of the quirky, cool little personalities to pop out. I used the [Fulltone] ’70 pedal. I played through that into the Demeter TGA-3 head, into my Fender Bandmaster cab with Vintage 30s.
You said you played the Demeter on the album. But readers would scream at me if I didn’t ask you about your Dumbles. Did they make the album?
Oh, yes. For sure. In fact, on one of my favorite tracks, “The Wilds of Wonder,” I played it with my ’60s Les Paul Standard sunburst. It’s a match made in heaven.
I always hate to say it, because everybody says, “Oh, here he goes talking about premium instruments and stuff.” But I’ll tell you that the humbuckers in that guitar, they don’t have the output or some of the type of sizzle that some PAFs have. It’s got its own thing. It’s unique, and it’s very subtle. With the Dumble, in particular, it’s perfect. I can dial it in, it articulates, and it actually comes out better than with other pickups. It’s a great combination, and it worked out well for that track.
What other amps did you use on the album?
I also used a ’65 blackface Bassman. And I used Komets. They’re great, man! They’re super high-quality. They hooked up with Ken Fischer [the late founder of Trainwreck amps] many years ago. They worked together and then branched off with their own designs.
Ken was like Alexander Dumble, in that he was a genius and a real eccentric. I talked to him a few times on the phone. He’d be able to listen to my amp over the phone call, then tell me how to tweak it for my slide playing. And sure enough, he was right!
The other thing: I got into using a Leslie again. I haven’t done that in a long time. I didn’t want to overdo it, but I think it added another level to the overall picture.
Several of those amps are famous for both their clean and dirty tones. Do you prefer to get your overdrive from your amps or pedals?
It’s both. Live, I run them clean and use the pedals that I have. I run into the Demeter Fuzzulator first, but I only use it for a boost. From the Fuzzulator it goes to Al Hermida’s Mosferatu pedal. That’s my main drive pedal. It’s a little amp in a box. You always hear people say that, but it actually is. From there, it goes to an Analog Man compressor. From the compressor, it goes to a Giggity by Voodoo Lab. Those are great—like a mastering EQ for guitar. They’re especially great for fattening up single-coil pickups.
Do you leave it on all the time?
Yes, I do. Then from there, into my Analog Man chorus pedal, and that will go into whatever delay unit. I’ve used different ones over the years. But on the last project, I used a Fulltone tape delay [Tube Tape Echo]. It’s like an Echoplex, but better. Then from there, it goes to the amp.

And I’ll use different guitars for different sounds and parts. For example, there may be something like “Mule,” where I had a really clean, chimey rhythm sound. That’s a late-’80s reissue of a ’50s Fender Stratocaster. I guess that would be a ’57 they were shooting for. I think that guitar sounds great. It’s got Lindy Fralin pickups. That would be the bed track. Then we went back and used one of my signature Fender prototypes with DiMarzio DP181 Fast Tracks. It’s my go-to pickup all these years.
Some of the other ones I love are Fishman’s Fluence pickups. I’ve been on the road with those, too. I like mixing those up, depending on the song. And then, of course, the humbuckers on the Les Paul. Those are some of the guitars I used for different parts.
Open tunings play a significant role in your music. What tunings did you use on Blacktop Run?
Well, it depends on the song. But on this album, whatever key they’re in, I’d generally tune to that. And I do this a lot, too, where I’m tuned to G, and we’ll be playing in Bb, F, or Eb. Then I can mix up different open strings within that tuning, or that key, or that mode. It’s a cool thing. You can tune to G and then play in A, getting a cool Lydian vibe.
I imagine you keep your tech plenty busy on the road.
Yes, he’s got a lot to do, man. We try to space them out so that I have three songs in the same tuning at a time.
Acoustic and resonator guitar play a big part on Blacktop Run. The tones on “Somebody Gotta Make a Move” are particularly beautiful.
Yes, man, I love that guitar. That’s my old ’69 Martin D-28. It’s aged over the years and become so rich and resonant. It has a really nice compression. It’s perfect for just about anything. For two years, 1970 to almost ’73, I didn’t even play electric guitar. I played that guitar and my resonators.
I also used a Pogreba resonator guitar, which is really cool. Bonnie Raitt has one, too. Larry Pogreba takes vintage hubcaps, and that’s what he uses for the cover plate on the body. And he makes the guitars out of aluminum, so they’re really light and have a different sound.
You did a Rig Rundown with us in July 2012. Has your live rig changed much since then?
Yes. Demeter made this mini amp [the TGA-1-180D Mighty Minnie]. It’s a little 4 1/2-pound travel amp. It has the same front end as a TGA-3, but the back end is Class-D power. It’s cool. It’s a great way to travel because it fits in my pedalboard case. And I always have a backline Twin in case anything goes wrong.
I’ll bet you blow a few of your fans’ minds when you show up to a gig with a mini, solid-state amp.
I’m sure [laughs]. I get asked about it every night. If I could bring all the other stuff out on a commercial airline, I would. Like, when we do the Crossroads festival for Eric Clapton, I bring it all. It’s so much fun. I’ll have the Dumble rig set up next to the Demeter, and I can switch back and forth.
What was it about playing slide guitar that initially attracted you?
I think that’s the vocal quality about it. Listening to the old Delta blues records, I didn’t realize it at the time, but my heroes were all using the slide to emulate the human voice. And I know a lot of the jazz cats do that. That’s what they want to do with their saxophone, trumpet, or whatever. They want to emulate that, to give it more expression, more soul. That’s what caught my ear.I couldn’t have articulated it as such back then, but that’s what I was hearing. And also, as time has gone on, realizing the potential it has for some of these different genres of music, it has served me well.
Today, players like Derek Trucks, Joey Landreth, and Ariel Posen are bringing electric slide to the forefront of guitar. And they credit your influence. What does that mean to you?
Well, it makes me feel great. It’s probably the best affirmation there is. I think they’re super-talented, creative, and they’re doing their own thing with it. And that’s the greatest compliment. I aspire to honor what my heroes did and what I got from them. Then I take that and find my own way with it, my own voice, and my own sound. And that’s what they’re doing. So, it’s as things should be.
