Two Channels from a Tube Guru
The Duo Tonic is the first pedal from Aspen Pittman Designs in San Fernando, California. (For those who recognize but can’t quite place the name, Aspen Pittman is the author of the much-revered The Tube Amp Book.) It is a dual-channel boost/overdrive/distortion pedal based around two sub-miniature 6502 pentode tubes, similar in size to the ones found in compact pedalboard amps and preamps, including the BluGuitar Amp1 or the Effectrode Fire Bottle.

The tube side has an almost amp-like feature set, providing a 3 band EQ along with a master volume, tone, and gain control. It remains relatively clean even when pushed, and its maximum gain tone sounds a bit like a Deluxe Reverb at the edge of breakup, with a focus on the highs and high-mids. It can get a little shrill with brighter guitars and pickups, so it is wise to make full use of the pedal’s tone and treble controls.
The second side is based around a JRC4558D, the op amp associated with TS-style circuits. While including a Tube Screamer-style drive might seem run-of-the-mill, the tones it helps generate are far from it, thanks in part to the way it works with the tube channel.
By itself, the tube side of the Duo Tonic isn’t especially colorful, but that can be a very good thing for a pre-amp style pedal—especially when you’re trying to maintain the essence of a good guitar/amp combo—and it has the mix of clarity and edge that vacuum tubes deliver so well. Clean tones are very hi-fi, with a hint of midrange warmth and a fair bit of high-end snap. When the solid-state circuit pushes the tubes, however, the overdrive and distortion sounds become very complex in both upper and lower harmonic registers. These can be very Dumble-esque. But you can also generate deep, complex, Klon-style low-gain overdrive tones. In fact, my ears prefer the Duo Tonic’s sounds in Klon-style modes.
The Verdict
The Duo Tonic puts a lot of tone-shaping potential at your feet. Both channels are independent, which is a huge plus in my book, and I really enjoyed running the different sides of this pedal with different guitars into different pedals. And while both sides can sound a little hi-fi or monochromatic when run independently with some guitars and amps, running the two channels together might find you giving thanks to the tone gods. It makes dark Les Pauls creamy and thick without sacrificing clarity, and makes bright Stratocasters and Telecasters sound and feel bigger and fatter. Better still, that hi-fi sheen accentuates all the right frequencies and stays intact when you stack the two channels. If you enjoy tone sculpting and can afford it, the Duo Tonic is a preamp/overdrive that’s not to be missed.
Onstage, Tommy Emmanuel executes a move that is not from the playbook of his hero, Chet Atkins.
“My biggest decision every day on tour is, ‘What do I want to start with? How do I want to come out of the gate?’” Emmanuel explains to me over a video call. “A good opener has to have everything. It has to be full of surprise, it has to have lots of good ideas, lots of light and shade, and then, hit it again,” he says, illustrating each phrase with his hands and ending with a punch.“You lift off straightaway with the first song, you get airborne, you start reaching, and then it’s time to level out and take people on a journey.”
In May 2023, Emmanuel played two shows at the Sydney Opera House, the best performances from which have been combined on his new release, Live at the Sydney Opera House. The venue’s Concert Hall, which has a capacity of 2,679, is a familiar room for Emmanuel, but I think at this point in his career he wouldn’t bring a setlist if he was playing Wembley Stadium. On the recording, Emmanuel’s mind-blowingly dexterous chops, distinctive attack and flair, and knack for culturally resonant compositions are on full display. His opening song for the shows? An original, “Countrywide,” with a segue into Chet Atkins’ “El Vaquero.”
“When I was going to high school in the ’60s, I heard ‘El Vaquero’ on Chet Atkins’ record, [1964’s My Favorite Guitars],” Emmanuel shares. “And when I wrote ‘Countrywide’ in around ’76 or ’77, I suddenly realized, ‘Ah! It’s a bit like “El Vaquero!”’ So I then worked out ‘El Vaquero’ as a solo piece, because it wasn’t recorded like that [by Atkins originally].
“The co-writer of ‘El Vaquero’ is Wayne Moss, who’s a famous Nashville session guy who played ‘da da da’ [sings the guitar riff from Roy Orbison’s ‘Pretty Woman’]. And he played on a lot of Chet’s records as a rhythm guy. So once when I played ‘El Vaquero’ live, Wayne Moss came up to me and said, ‘You know, you did my part and Chet’s at the same time. That’s not fair!’” Emmanuel says, laughing.
Atkins is the reason Emmanuel got into performing. His mother had been teaching him rhythm guitar for a couple years when he heard Atkins on the radio and, at 6, was able to immediately mimic his fingerpicking technique. His father recognized Emmanuel’s prodigious talent and got him on the road that year, which kicked off his professional career. He says, “By the time I was 6, I was already sleep-deprived, working too hard, and being forced to be educated. Because all I was interested in was playing music.”
Emmanuel talks about Atkins as if the way he viewed him as a boy hasn’t changed. The title Atkins bestowed upon him, C.G.P. (Certified Guitar Player), appears on Emmanuel’s album covers, in his record label (C.G.P. Sounds), and is inlaid at the 12th fret on his Maton Custom Shop TE Personal signature acoustic. (Atkins named only five guitarists C.G.P.s. The others are John Knowles, Steve Wariner, Jerry Reed, and Atkins himself.) For Emmanuel, even today most roads lead to Atkins.
When I ask Emmanuel about his approach to arranging for solo acoustic guitar, he says, “It was really hit home for me by my hero, Chet Atkins, when I read an interview with him a long time ago and he said, ‘Make your arrangement interesting.’ And I thought, ‘Wow!’ Because I was so keen to be true to the composer and play the song as everyone knows it. But then again, I’m recreating it like everyone else has, and I might as well get in line with the rest of them and jump off the cliff into nowhere. So it struck me: ‘How can I make my arrangements interesting?’ Well, make them full of surprises.”
When Emmanuel was invited to contribute to 2015’s Burt Bacharach: This Guitar’s in Love with You, featuring acoustic-guitar tributes to Bacharach’s classic compositions by various artists, Emmanuel expresses that nobody wanted to take “(They Long to Be) Close to You,” due to its “syrupy” nature. But for Emmanuel, this presented an entertaining challenge.
He explains, “I thought, ‘Okay, how can I reboot “Close to You?’ So even the most jaded listener will say, ‘Holy fuck—I didn’t expect that! Wow, I really like that; that is a good melody!’ So I found a good key to play the song in, which allowed me to get some open notes that sustain while I move the chords. Then what I did is, in every phrase, I made the chord unresolve, then resolve.

“And then to really put the nail in the coffin, at the end, ‘Close to you’ [sings melody]. I finished on a major 9 chord which had that note in it, but it wasn’t the key the song was in, which is a typical Stevie Wonder trick. All the tricks I know, the wonderful ideas that I’ve stolen, are from Michael Jackson, Stevie Wonder, Lionel Richie, James Taylor, Carole King, Neil Diamond. All of the people who wrote really incredibly great pop songs and R&B music—I stole every idea I could, and I tried to make my little two-and-a -half minutes as interesting and entertaining as possible. Because entertainment equals: Surprise me.”
I share with Emmanuel that the performances on Live at the Sydney Opera House, which include his popular “Beatles Medley,” reminded me of another possible arrangement trick. In Harpo Marx’s autobiography, Harpo Speaks, I preface, Marx writes of a lesson he learned as a performer—to “answer the audience’s questions.” (Emmanuel says he’s a big fan of the book and read it in the early ’70s.) That happened for me while listening to the medley, when, after sampling melodies from “She’s a Woman” and “Please Please Me,” Emmanuel suddenly lands on “While My Guitar Gently Weeps.”
I say, “I’m waiting for something that hits more recognizably to me, and when ‘While My Guitar’ comes in, that’s like answering my question.”
“It’s also Paul and John, Paul and John, George,” Emmanuel replies. “You think, ‘That’s great, that’s great pop music,’ then, ‘Wow! Look at the depth of this.’”
Often Emmanuel’s flights on his acoustic guitar are seemingly superhuman—as well as supremely entertaining.

A trick I like to employ as a writer, I say to Emmanuel, is that when I’m describing something, I’ll provide the reader with just enough context so that they can complete the thought on their own.
“You can do that musically as well,” says Emmanuel. He explains how, in his arrangement of “What a Wonderful World,” he’ll play only the vocal melody. “When people are asking me at a workshop, ‘How come you don’t put chords behind that part?’ I say, ‘I’m drawing the melody and you’re putting in all the background in your head. I don’t need to tell you what the chords are. You already know what the chords are.’”
“Wayne Moss came up to me and said, ‘You know, you did my part and Chet’s at the same time. That’s not fair!’”
Another track featured on Live at the Sydney Opera House is a cover of Paul Simon’s “American Tune” (which Emmanuel then jumps into an adaptation of the Australian bush ballad, “Waltzing Matilda”). It’s been a while since I really spent time with There GoesRhymin’ Simon (on which “American Tune” was first released), and yet it sounded so familiar to me. A little digging revealed that its melody is based on the 17th-century Christian hymn, “O Sacred Head, Now Wounded,” which was arranged and repurposed by Bach in a few of the composer’s works. The cross-chronological and genre-lackadaisical intersections that come up in popular music sometimes is fascinating.
“I think the principle right there,” Emmanuel muses, “is people like Bach and Beethoven and Mozart found the right language to touch the heart of a human being through their ears and through their senses ... that really did something to them deep in their soul. They found a way with the right chords and the right notes, somehow. It could be as primitive as that.

“It’s like when you’re a young composer and someone tells you, ‘Have a listen to Elton John’s “Candle in the Wind,”’ he continues. “‘Listen to how those notes work with those chords.’ And every time you hear it, you go, ‘Why does it touch me like that? Why do I feel this way when I hear those chords—those notes against those chords?’ I say, it’s just human nature. Then you wanna go, ‘How can I do that!’” he concludes with a grin.
“You draw from such a variety of genres in your arrangements,” I posit. “Do you try to lean into the side of converting those songs to solo acoustic guitar, or the side of bridging the genre’s culture to that of your audience?”
“I stole every idea I could, and I tried to make my little two-and-a-half minutes as interesting and entertaining as possible. Because entertainment equals: Surprise me.”
“If I was a method actor,” Emmanuel explains, “what I’m doing is—I’m writing music for the film that’s in my head. So, I don’t think, ‘I’m just the guitar,’ ever. I always think it has to have that kind of orchestral, not grandeur, but … palette to it. Because of the influence of Stevie Wonder, Billy Joel, and Elton John, especially—the piano guys—I try to use piano ideas, like putting the third in the low bass a lot, because guitar players don’t necessarily do that. And I try to always do something that makes what I do different.
“I want to be different and recognizable,” he continues. “I remember when people talked about how some players—you just hear one note and you go, ‘Oh, that’s Chet Atkins.’ And it hit me like a train, the reason why a guy like Hank Marvin, the lead guitar player from the Shadows.... I can tell you: He had a tone that I hear in other players now. Everyone copied him—they just don’t know it—including Mark Knopfler, Eric Clapton, Jimmy Page, all those people. I got him up to play with me a few times when he moved to Australia, and even playing acoustic, he still had that sound. I don’t know how he did it, but it was him. He invented himself.”

Emmanuel performs his arrangement of “What a Wonderful World,” illustrating how omitting a harmonic backdrop can have a more powerful effect, especially when playing such a well-known melody.
The Rickenbacker 481’s body style was based on the 4001 bass, popularly played by Paul McCartney. Even with that, the guitar was too experimental to reach its full potential.
By the early 1970s, the great interest the lads had sparked in 6- and 12-string Ricks had waned. But thankfully for the company, there was still high demand for yet another Beatles-played instrument: the 4001 bass.
Paul McCartney was gifted a 4001 by Rickenbacker in 1965, which he then used prominently throughout the group’s late-’60s recordings and while leading Wings all through the ’70s. Other rising stars of rock also donned 4000 series models, like Yes’Chris Squire, Pink Floyd’sRoger Waters, the Bee Gees’ Maurice Gibb, Creedence Clearwater Revival’s Stu Cook, and more.
And like that, a new star was born.
So, what’s a guitar company to do when its basses are selling better than its guitars? Voilà: The Rickenbacker 480. Introduced in 1972, it took the 4000-series body shape and created a standard 6-string out of it, using a bolt-on neck for the first time in the brand’s history.
The 481’s slanted frets predate the modern multi-scale phenomenon by decades. The eight-degree tilt of the frets is matched by an eight-degree tilt of the nut, pickups, and bridge.
“It was like a yo-yo at Rickenbacker sometimes,” factory manager Dick Burke says in Rickenbacker Guitars: Out of the Frying Pan Into the Fireglo. “We got quiet in the late ’60s, but when the bass started taking off in the ’70s, we got real busy again, so making a 6-string version of that was logical, I guess.”
The gambit worked, for a time. Sales of the 480 were strong enough at first that, in 1973, a deluxe model was introduced—the 481—and it’s one of these deluxe versions that we’re showcasing here.
“The 481 features slant frets—pointing ever-so-slightly toward the body of the guitar—and the eight-degree tilt of the frets is matched by an eight-degree tilt of the nut, pickups, and bridge.”
Take a close look and you’ll notice that the body shape isn’t the only remarkable feature. The 481 was Rickenbacker’s first production run to feature humbucker pickups. Here, you can see each humbucker’s 12 pole pieces dotting through the chrome cover, a variant casing only available from 1975 to 1976. (Interestingly enough, the pickups had first been developed for the 490, a prototype that never made it to public release, which would’ve allowed players to substitute different pickups by swapping loaded pickguards in and out of the body.)
The new pickups were also treated with novel electronics. The standard 3-way pickup-selector switch is here, but so is a second small switch that reverses the pickups’ phase when engaged.
The inventive minds at Rickenbacker didn’t stop there: The 481 features slant frets—pointing ever-so-slightly toward the body of the guitar—and the eight-degree tilt of the frets is matched by an eight-degree tilt of the nut, pickups, and bridge.
Long before the fanned fret phenomenon caught on in the modern, progressive guitar landscape, Rickenbacker had been toying around with the slant-fret concept. Originally available from 1970 forward as a custom order on other models, slant frets were all but standard on the 481 (only a small minority of straight-fret 481s were built).
The 481 was the deluxe version of the 480, which preceded it and marked the first time the company used a bolt-on neck.
Dick Burke, speaking separately to writer Tony Bacon in an interview published on Reverb, only half-recalls the genesis and doesn’t remember them selling particularly well: “Some musicians said that’s the way when you hold the neck in your left hand—your hand is slanted. So, we put the slanted frets in a few guitars. I don’t know how many, maybe a hundred or two—I don’t recall.”
Even proponents of the 481 do not necessarily sing the praises of the slanted fretboard. Kasabian’s Serge Pizzorno, a 481 superfan, told Rickenbacker Guitars author Martin Kelly, “I don’t just love the 481, it’s part of me.... The 481’s slanted frets have made my fingers crooked for life, but I don’t care, I’ll take that for it’s given me riff after riff after riff."
Initial 480-series sales were promising, but the models never really took off. Though they were built as late as 1984, the slant-fret experiment of the 481 was called off by 1979. And these slanted models have not, in the minds of most players or collectors, become anywhere near as sought-after as the classic 330s and 360s, or, for that matter, the 4001s.
For that reason, 481s—despite their novelty and their lists of firsts for Rickenbacker—can still be found for relatively cheap. Our Vintage Vault pick, which is being sold by the Leicester, England-based Jordan Guitars Ltd, has an asking price of 3,350 British pounds (or about 4,300 U.S. dollars), which is still well under half the going-rate of early 360s, 660s, and other more famous Ricks. Some lucky buyers have even found 481s on Reverb for less than $2,000, which is unheard of for other vintage models.
With its idiosyncratic charms, the 481 remains more within reach than many other guitars of a similar vintage.
