Neural DSP Nano Cortex

The complexities and capabilities of modelers like Neural DSP’s Cortex series demand certain tradeoffs. For starters, a powerful modeler can’t be the size of a postage stamp, at least if you intend to adjust many parameters and source numerous presets in real time on a stage. Neural’s newNano Cortex pushes back at the boundaries of that compromise. It's not much wider than two MXR pedals side by side. The $549 price tag, which is just about a third of the price of the Nano’s more capable big brother,the Quad Cortex, makes it an appealing proposition too.
Taken at Face Value
The Nano Cortex is a streamlined piece of hardware. An array of five push buttons enables signal capture and navigation of banks and effects. Two rotary bypass footswitches also move through presets and effects blocks, and six knobs (with LED surrounds that display levels) govern gain, output level, EQ, and wet/dry effects blend. The big omission here is, of course, a screen that displays signal effects chains and preset names. That job, if you choose to use the Nano in that fashion, falls to the Cortex Cloud app and a smartphone or tablet, meaning you’ll need two pieces of hardware on hand to make the most of the Nano’s potential. You can use the Nano in performance without a phone or tablet. But you’ll need to have a photographic memory of what presets are made up of what amps and effects, which gets extra tricky if you use wildly divergent sounds designed to work at vastly different output levels.
Many sounds from the Nano Cortex are fantastic. Many of the factory presets—particularly those dressed up with a little gain, will probably fool listeners in a blind test when those sounds are situated in a mix, and can be fairly classified as authentic in most cases. Like any modeler, the accuracy of modeled tones doesn’t mean that dynamic interactions with those same models will feel the same way, especially if you use feedback and the overtones and harmonics generated via amp proximity in your expression. For guitarists that don’t integrate these methods into their playing, the Nano’s sounds will be more than satisfactory stand-ins for their analog equivalents.
A Captive Audience
Modelers love the convenience of capture technology—the ability to clone the characteristics of many amps and pedals in your collection, which you can then take on the road, to a gig, or practice in a compact floor unit. It’s a very appealing and practical idea, particularly if you’re playing anywhere where parking in front of the venue isn’t a given. Neural’s capture method is fast and easy. To capture an amp’s personality, you mike an amp (or send the signal via a load box) to the Nano Cortex, run a signal from the Nano to your amp, press capture, listen for the test signals and kick back for five minutes while the unit does its thing. The process is fundamentally easy. And it enables you to stuff an approximation of your favorite amp, or 10, in the pocket of a gig bag. It’s also what makes the tone library crowd sourced by the constantly growing and dedicated Cortex artist and user community so extensive.
“Nano Cortex’s capture process is fundamentally easy. And it enables you to stuff an approximation of your favorite amp, or ten, in the pocket of a gig bag.”
But while you can conceivably nail the sound of your amp, or pedal, to the letter in five minutes, achieving the best possible approximation can take many tries—particularly if you use the amp-miking method. Though I got close, I never quite hit the bullseye in my attempts. The same mic placement, amp settings, and audio interface all sounded more expansive and livelier when tracked live than via a capture. Would I love to have close-but-not-quite approximations of my favorite three different amps on a fly date? You bet—especially if I could situate a few key, favorite pedals on a small pedalboard with the Nano.
The Verdict
Though there is no shortage of serviceable sounds built into the Nano Cortex, the real action will, for many, be the abundance of captures and sounds created via the larger Cortex community. This is no bad thing—especially if you have the time to cruise and create these sounds at leisure. There’s no reason that any of these sounds can’t become solid foundations for core live tones. But time spent exploring an extensive online library of captures or creating them is time not spent creating songs. So, for many players, Nano Cortex will be a better bet for home recording than for performance or in a deadline-driven studio situation. This is made doubly true for the lack of the onboard editing interface and the Nano Cortex reliance on a smartphone or tablet for deeper editing. Adding a second piece of gear compounds the risks inherent in an already complex technology.
Still, the number of available presets is considerable, and players with gigs that require spanning multiple styles in a night will have so much to work with here if they manage without a screen and trust their phone. In terms of achieving sheer processing power in a small size, the Nano Cortex is tough to beat. And for those that savor the experience of creating and sourcing a huge library of sounds in a unit with the footprint of a sandwich, thrills and big-time dividends await.

Onstage, Tommy Emmanuel executes a move that is not from the playbook of his hero, Chet Atkins.
Recorded live at the Sydney Opera House, the Australian guitarist’s new album reminds listeners that his fingerpicking is in a stratum all its own. His approach to arranging only amplifies that distinction—and his devotion to Chet Atkins.
Australian fingerpicking virtuoso Tommy Emmanuel is turning 70 this year. He’s been performing since he was 6, and for every solo show he’s played, he’s never used a setlist.
“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.

“I’m writing music for the film that’s in my head,” Emmanuel says. “So, I don’t think, ‘I’m just the guitar,’ ever.”

“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.”

Featuring a newly-voiced circuit with more compression and versatility, these pedals are hand-crafted in Los Angeles for durability.
Messiah Guitars custom shop has launched a pair of new pedals: The Eddie Boostdrive Session Edition and Lil’ Ed Session Drive.
The two pedals are full-size and mini-sized versions of a newly-voiced circuit based on Messiah’s successful Eddie Boostdrive. The two new “Session” pedals feature more compression and versatility in the overall tone, and showcase Messiah’s ongoing collaboration with Nashville session guitarist Eddie Haddad.
The new Session Boostdrive schematic includes a fine-tuned EQ section (eliminating the need for the Tight switch on the earlier Boostdrive) and two independently operated circuits: a single-knob booster, and a dual-mode drive featuring a 3-band EQ. The booster consists of a single-stage MOSFET transistor providing boost ranging from -3dB to 28dB. At low settings, the boost adds sparkle to the tone, while a fully cranked setting will send your amp to a fuzzy territory. Thebooster engagement is indicated by a purple illuminated foot switch.
The overdrive contains a soft-clipped op-amp stage, inspired by a screamer-style circuit. The pedal includes a classic Silicon clipping mode (when activated, the pedal’s indicator light is blue)and an LED mode for a more open, amp-like break up (indicator light is red).
The active 3-band EQ is highly interactive and capable of emulating many popular drive sounds. Although both effects can be used separately, engaging them simultaneously produces juicy tones that will easily cut through the mix. Both new pedals accept a standard 9V pedal power supply with negative center pin.
“I love my original Boostdrive,” says Haddad, “but I wanted to explore the circuit and see if we could give it more focused features. This would make it more straightforward for guitarists who prefer simplicity in their drive pedals. The boost is super clean and loud in all the right ways…it can instantly sweeten up an amp and add more heft and sparkle to the drive section.”
Like their custom guitars and amplifiers, Messiah’s pedals are hand-crafted in Los Angeles for durability and guaranteed quality.
The Lil’ Ed Session Drive pedal includes:
- 5-knob controls, a 2-way mode side switch
- Durable, space-saving cast aluminum alloy 1590A enclosure with fun artwork
- True bypass foot switch
- Standard 9V/100mA pedal power input
The Eddie Session Edition pedal features:
- 6-knob controls, a 2-way mode switch; space-saving top-side jacks
- Durable, cast aluminum alloy 125B enclosure with fun artwork
- Easy to see, illuminated optical true bypass foot switches
- Standard 9V/100mA pedal power input
The Eddie Boostdrive Session Edition retails for $249.00, and the Lil’ Ed Session Drive for$179.
