Iriondo has been a member of the Italian alt-rock outfit Afterhours since 1992. Here he’s playing a custom Epiphone SG Custom at an Afterhours show in 2015.
Italian guitarist and sonic adventurer Xabier Iriondo has an affinity for the Basque term, metak—which literally means, “pile”—and he often incorporates it into the names of his various projects. His custom-built experimental guitar is the Mahai Metak (or “table pile”). Some of his unconventional musical collaborations also include the term, as in PhonoMetak and PhonoMetak Labs. And Sound Metak was the name of the eclectic shop he ran for about a decade in the early 2000s, which sold everything from boutique guitar pedals to shoes. (Check out his Instagram profile, which, in addition to pictures of his amazing collection of guitars, pedals, and vintage amps, is also a showcase for his impeccable taste in footwear).
“I am half Basque,” Iriondo says. “And these words—like “mahai” and “metak”—come from the Basque language. A metak is when you take the grass that you’re cutting, and you make a mountain of this grass in the garden. In the past, you gave this metak to the cows.” Another traditional Basque practice and type of metak involves shredding and drying corn stalks to use as fodder over the long, cold winter months. So, a metak is a pile of collected things that are preserved for an extended period. In Iriondo’s view, this serves as an analogy for something deeper. “I love this idea, because you can put everything inside the metak,” he says. “It’s like a collection of your emotions. For example, with my shop, Sound Metak, I sold different kinds of things—from old gramophones and vinyl shellac records to fuzz pedals and jukeboxes and guitars and amplifiers—it was a lot of different things. Metak for me is an idea, and my instrument, the Mahai Metak, is the same thing. It’s an energy from my fantasy, which is everything I can put out from my mind.”
Buñuel is a noise-rock quartet named after the legendary Spanish filmmaker, Luis Buñuel. The band formed was formed in 2016 by (from left to right) bassist Andrea Lombardini, drummer Francesco Valente, American vocalist Eugene S. Robinson, and guitarist Xabier Iriondo.
Conceptually, metak also helps to explain Iriondo’s musical diversity. Born in Milan, he started playing the guitar at 17, and became something of an Italian celebrity as part of the alternative band Afterhours, with whom he’s been a member since 1992 (except for hiatus throughout most of the aughts). But Afterhours is about as mainstream as Xabier gets. He’s also made incredible noise with myriad projects, like his recordings and performances with Can’s Damo Suzuki (Damo Suzuki’s Network), collaborations with the cream of Europe’s avant-garde (?Alos, Pleiadees), numerous solo projects, and the list goes on and on.
Xabier Iriondo's pedalboard: “When you’re using some of these destruction pedals on the loud and heavy stuff, the guitar isn’t so important. You destroy everything with these kinds of pedals."
His most recent outing is the abrasive, apocalyptic, noise-rock quartet Buñuel. Named after the legendary Spanish filmmaker Luis Buñuel, the band first came together in 2016 and mixes the talents of a trio of Italian musicians—Iriondo, bassist Andrea Lombardini, and drummer Francesco Valente—plus American vocalist Eugene S. Robinson. Their new release, Killers Like Us, is awash in fuzz and rages between brain-crushing, metal-tinged cuts like “A Prison of Measured Time” and “When God Used a Rope” to slow, doomy dirges like “Hornets” and “When We Talk,” as well as moments of unstructured, free improvisation interspersed throughout the record.
BUNUEL - When God Used A Rope (official video)
“We are three Italian musicians,” Iriondo says about Buñuel’s genesis. “We were a little bit famous here in Italy, and we decided to choose an international singer. We wrote to Eugene Robinson, and he accepted our idea. For our first record, the three of us recorded 10 songs in a studio in Italy. We sent them to Eugene in San Francisco, he sang on them, and then sent the tracks back to us. We did that again for this record.” Not only were the vocals recorded separate from the rest of the band, but Robinson didn’t even get a chance to rehearse with them. The first time the band played together as a quartet was onstage in front of an audience. “We didn’t rehearse with Eugene—we rehearsed ourselves—and we met with him the first day of the first gig. That’s how it started.”
Despite Iriondo’s years of experience with group improvisation, that was not the approach he took with Buñuel. You’d think improv would be helpful when stepping onstage raw with an unrehearsed new singer. Rather, the band’s vibe is through-composed songs that are played the same way—except for planned sections set aside for improvisation—night after night.
“When I want to take a solo, I adjust the Cornish directly with my foot. I open up the volume, and then I arrive in the cosmos.”
“We play the songs like they are on the album,” says Iriondo. “Although we do have some parts, or structures, that can change. For example, on our first tour, we wrote our 10 songs, and that’s all we had. At the end of the show, the audience asked for more. I said, ‘Okay, let’s start with an improv,’ and that improv we used on those gigs from the first tour became a song on the second album [“The Sanction” o 2018'sThe Easy Way Out]. We composed each day, each gig, and the song transformed and arrived at the end of the tour.”
When recording Buñuel, Iriondo harnesses that live feel by taking a minimalist approach to overdubs. Aside from an odd guitar solo or two, the instruments are recorded live, with the band members standing together and looking at each other. “I also play pop rock with other bands, and overdubbing is okay for that kind of music, but the wildness of this project gains a lot when we’re all playing together in the same room,” he says.
For both of Buñuel’s albums, including the new Killers Like Us, the three Italian core band members recorded the songs in Italy and sent them to vocalist Eugene Robinson in San Francisco. Robinson sang over the music and then sent the tracks back to Italy.
“In the past, in the ’90s, I used the VHT head system that people talked about,” he says about the now-rebranded Fryette Pittbull Ultra-Lead. “I bought the second one that arrived in Italy in 1994. But in the last 20-to-25 years, I started using theHiwatt DR103, and I think that’s my sound. When I plugged in for the first time, I said, ‘What the hell is this?’ I can go from high-frequency, crystal-like sounds to really deep grunge sounds with a lot of low frequencies. In general, with Buñuel and also Afterhours, I use the Hiwatt, and then also another amp, a 300-watt SWR California Blonde, which is a transistor amp. I have the headroom also in the clean sounds, but when I engage all my fuzzes and boosters, the gain is incredible, and it’s still in front of you all the time.”
“I love this idea, because you can put everything inside the metak. It’s like a collection of your emotions.”
Iriondo’s tone is wild, too. Considering how mangled, heavy, and distorted his sound gets, it’s interesting how he crafts his tone almost exclusively with pedals, which he uses to drive his amps. He owns more than 20 heads and cabs, and his preference is classic British amps like Hiwatt, Orange, Carlsbro, and Simms Watt—he has a few of each in assorted colors—that have a lot of headroom. He feels those work best with his high-gain pedals.
Xabier Iriondo’s Gear
Xabier Iriondo’s custom-built "Mahai Metak" is a 10-string short-scale table guitar. Six of the strings are tuned to D in different octaves and act as drones. The other four are G, G, F, and A. It has pickups on both ends, plus an onboard oscillator and distortion unit, and controls for volume and tone. "I play it with Chinese sticks, and I create rhythms and special sounds with steel wool—that stuff you use in America to wash your dishes. It sounds great."

Iriondo has a seemingly endless collection of pedals, too, although his go-to is his signature octave-synth-fuzz-boost Arpiona, made by Italian builders AC Noises. The pedal starts with a gated fuzz circuit inspired by Death By Audio’s Harmonic Transformer, followed by a sub-octave bass synth, more fuzz, and a boost. He uses that in conjunction with an EarthQuaker Devices Acapulco Gold, and a Pete Cornish NB-2 boost that’s always engaged. “When I want to take a solo,” he says, “I adjust the Cornish directly with my foot. I open up the volume, and then I arrive in the cosmos.”
Afterhours - Spreca una vita
They’re Italian, which is probably why this Afterhours video looks like a Federico Fellini film.
Iriondo is also no purist. If an analog circuit will get him the sound he wants, great, but he’s just as happy using a digital device. “I use everything that can give me satisfaction,” he says. “Why not?”
Why not, indeed. He also gets that satisfaction from his guitars. “About 80 percent of my choice in guitars is the feel, and 20 percent is the sound,” he says. “When you’re using some of these destruction pedals on the loud and heavy stuff, the guitar isn’tso important. You destroy everything with these kinds of pedals. They completely destroy your clean sound. Although when I play pop-rock music, I change my guitars a lot.”
Xabier Iriondo bought his James Trussart Red Star Steelcaster directly from the luthier at his L.A. home in 2012. It features a metal front and back perforation body, maple neck, rosewood fretboard, and two Arcane Inc. pickups.

But that feel is elusive, which may explain Iriondo’s vast collection of instruments. He has vintage guitars he doesn’t mod at all, but in general he’s an itinerant tinkerer. He usually swaps out pickups, even on his less expensive guitars, and has a significant number of custom-built guitars as well. “I’m not only a collector, I’m a professional, which means guitars are my life,” he says. “I want to have tools that work well with me. In the last few years, I’ve had the opportunity to have my dream guitars that I ask luthiers to build for me with my specific specifications. The principal guitar that I used on the Buñuel project is made by Billy Boy Guitars. It has an incredible tremolo, and it’s a light guitar. All the sounds you hear on Buñuel are made with that guitar.”
Perhaps Iriondo’s most unique instrument is his custom-built Mahai Metak. It’s a 10-string, short-scale table guitar. Six of the strings are tuned to D in different octaves and act as drones. The other four are G, G, F, and A. The instrument has pickups on both ends—near the bridge as well as near the nut—plus an onboard oscillator and distortion unit, and controls for volume and tone. He plays it with an assortment of items, including marbles, roach clips, and steel wool. “I play it with Chinese sticks,” he says, “and I create rhythms and special sounds with steel wool—that stuff you use in America to wash your dishes. It sounds great. I use it with the loopers and reverbs and it creates these noisy and bizarre sounds, as well as melodic sounds that create a nice texture.”

It’s that openness and wonder, as exemplified by Iriondo’s voracious appetite for gear, as well as his embrace of disparate genres and styles, that are the ingredients that make up his metak. Call it his esoteric pile of ideas, which gives him permission to explore the endless energies of his imagination. He’ll conjure up sounds that are heavy and dark—or playful and light—and almost always fun, and, maybe, even a little mischievous.
And isn’t that, ultimately, the ideal?

Submarine Pickups boss Pete Roe at his workstation.
Still, we think we know what pickups should sound and look like. Lucky for us, there have always been plenty of pickup builders who aren’t so convinced. These are the makers who devised the ceramic-magnet pickup, gold-foils, and active, high-gain pickups. In 2025, nearly 100 years after the first pickup bestowed upon a humble lap-steel guitar the power to blast our ears with soundwaves, there’s no shortage of free-thinking, independent wire-winders coming up with new ways to translate vibrating steel strings into thrilling music.
Joe Naylor, Chris Mills, and Pete Roe are three of them. As the creative mind behind Reverend Guitars, Naylor developed the Railhammer pickup, which combines both rail and pole-piece design. Mills, in Pennsylvania, builds his own ZUZU guitars with wildly shaped, custom-designed pickups. And in the U.K., Roe developed his own line of hexaphonic pickups to achieve the ultimate in string separation and note definition. All three of them told us how they created their novel noisemakers.
Joe Naylor - Railhammer Pickups
Joe Naylor, pictured here, started designing Railhammers out of personal necessity: He needed a pickup that could handle both pristine cleans and crushing distortion back to back.
Like virtually all guitar players, Joe Naylor was on a personal tone quest. Based in Troy, Michigan, Naylor helped launch Reverend Guitars in 1996, and in the late ’90s, he was writing and playing music that involved both clean and distorted movements in one song. He liked his neck pickup for the clean parts, but it was too muddy for high-gain playing. He didn’t want to switch pickups, which would change the sound altogether.
He set out to design a neck pickup that could represent both ends of the spectrum with even fidelity. That led him to a unique design concept: a thin, steel rail under the three thicker, low-end strings, and three traditional pole pieces for the higher strings, both working with a bar magnet underneath. At just about a millimeter thick, rails, Naylor explains, only interact with a narrow section of the thicker strings, eliminating excess low-end information. Pole pieces, at about six millimeters in diameter, pick up a much wider and less focused window of the higher strings, which works to keep them fat and full. “If you go back and look at some of the early rail pickups—Bill Lawrence’s and things like that—the low end is very tight,” says Naylor. “It’s almost like your tone is being EQ’d perfectly, but it’s being done by the pickup itself.”
That idea formed the basis for Railhammer Pickups, which began official operations in 2012. Naylor built the first prototype in his basement, and it sounded great from the start, so he expanded the format to a bridge pickup. That worked out, too. “I decided, ‘Maybe I’m onto something here,’” says Naylor. Despite the additional engineering, Railhammers have remained passive pickups, with fairly conventional magnets—including alnico 5s and ceramics—wires, and structures. Naylor says this combines the clarity of active pickups with the “thick, organic tone” of passive pickups.
“It’s almost like your tone is being EQ’d perfectly, but it’s being done by the pickup itself.” —Joe Naylor
The biggest difficulty Naylor faced was in the physical construction of the pickups. He designed and ordered custom molds for the pickup’s bobbins, which cost a good chunk of money. But once those were in hand, the Railhammers didn’t need much fiddling. Despite their size differences, the rail and pole pieces produce level volume outputs for balanced response across all six strings.
Naylor’s formula has built a significant following among heavy-music players. Smashing Pumpkins’ Billy Corgan is a Railhammer player with several signature models; ditto Reeves Gabrels, the Cure guitarist and David Bowie collaborator. Bob Balch from Fu Manchu and Kyle Shutt from the Sword have signatures, too, and other players include Code Orange’s Reba Meyers, Gogol Bordello’s Boris Pelekh, and Voivod’s Dan “Chewy” Mongrain.
Chris Mills - ZUZU Pickups
When Chris Mills started building his own electric guitars, he decided to build his own components for them, too. He suspected that in the course of the market’s natural thinning of the product herd, plenty of exciting options had been left unrealized. He started working with non-traditional components and winding in non-traditional ways, which turned him on to the idea that things could be done differently. “I learned early on that there are all kinds of sonic worlds out there to be discovered,” says Mills.
Eventually, he zeroed in on the particular sound of a 5-way-switch Stratocaster in positions two and four: Something glassy and clear, but fatter and more dimensional. In Mills’ practice, “dimensional” refers to the varying and sometimes simultaneous sound qualities attained from, say, a finger pad versus a fingernail. “I didn’t want just one thing,” says Mills. “I wanted multiple things happening at once.”
Mills wanted something that split the difference between a humbucker’s fullness and the Strat’s plucky verve, all in clean contexts. But he didn’t want an active pickup; he wanted a passive, drop-in solution to maximize appeal. To achieve the end tone, Mills wired his bobbins in parallel to create “interposed signal processing,” a key piece of his patented design. “I found that when I [signal processed] both of them, I got too much of one particular quality, and I wanted that dimensionality that comes with two qualities simultaneously, so that was essential,” explains Mills.
Mills loved the sound of alnico 5 blade magnets, so he worked with a 3D modeling engineer to design plastic bobbins that could accommodate both the blades and the number of turns of wire he desired. This got granular—a millimeter taller, a millimeter wider—until they came out exactly right. Then came the struggle of fitting them into a humbucker cover. Some key advice from experts helped Mills save on space to make the squeeze happen.
Mills’ ZUZUbuckers don’t have the traditional pole pieces and screws of most humbuckers, so he uses the screw holes on the cover as “portholes” looking in on a luxe abalone design. And his patented “curved-coil” pickups feature a unique winding method to mix up the tonal profile while maintaining presence across all frequencies.
“I learned early on that there are all kinds of sonic worlds out there to be discovered.” —Chris Mills
Mills has also patented a single-coil pickup with a curved coil, which he developed to get a different tonal quality by changing the relative location of the poles to one another and to the bridge. Within that design is another patented design feature: reducing the number of turns at the bass end of the coil. “Pretty much every pickup maker suggests that you lower the bass end [of the pickup] to compensate for the fact that it's louder than the treble end,” says Mills. “That'll work, but doing so alters the quality and clarity of the bass end. My innovation enables you to keep the bass end up high toward the strings.”
Even Mills’ drop-in pickups tend to look fairly distinct, but his more custom designs, like his curved-coil pickup, are downright baroque. Because his designs don’t rely on typical pickup construction, there aren’t the usual visual cues, like screws popping out of a humbucker cover, or pole pieces on a single-coil pickup. (Mills does preserve a whiff of these ideals with “portholes” on his pickup covers that reveal that pickup below.) Currently, he’s excited by the abalone-shell finish inserts he’s loading on top of his ZUZUbuckers, which peek through the aforementioned portholes.
“It all comes down to the challenge that we face in this industry of having something that’s original and distinctive, and also knowing that with every choice you make, you risk alienating those who prefer a more traditional and familiar look,” says Mills.
Pete Roe - Submarine Pickups
Roe’s stick-on Submarine pickups give individual strings their own miniature pickup, each with discrete, siloed signals that can be manipulated on their own. Ever wanted to have a fuzz only on the treble strings, or an echo applied just to the low-register strings? Submarine can achieve that.
Pete Roe says that at the start, his limited amount of knowledge about guitar pickups was a kind of superpower. If he had known how hard it would be to get to where he is now, he likely wouldn’t have started. He also would’ve worked in a totally different way. But hindsight is 20/20.
Roe was working in singer-songwriter territory and looking to add some bass to his sound. He didn’t want to go down the looping path, so he stuck with octave pedals, but even these weren’t satisfactory for him. He started winding his own basic pickups, using drills, spools of wire, and magnets he’d bought off the internet. Like most other builders, he wanted to make passive pickups—he played lots of acoustic guitar, and his experiences trying to find last-minute replacement batteries for most acoustic pickups left him scarred.
Roe started building a multiphonic pickup: a unit with multiple discrete “pickups” within one housing. In traditional pickups, the vibration from the strings is converted into a voltage in the 6-string-wide coils of wire within the pickup. In multiphonic pickups, there are individual coils beneath each string. That means they’re quite tiny—Roe likens each coil to the size of a Tylenol pill. “Because you’re making stuff small, it actually works better because it’s not picking up signals from adjacent strings,” says Roe. “If you’ve got it set up correctly, there’s very, very little crosstalk.”
With his Submarine Pickups, Roe began by creating the flagship Submarine: a quick-stick pickup designed to isolate and enhance the signals of two strings. The SubPro and SubSix expanded the concept to true hexaphonic capability. Each string has a designated coil, which on the SubPro combine into four separate switchable outputs; the SubSix counts six outputs. The pickups use two mini output jacks, with triple-band male connectors to carry three signals each. Explains Roe: “If you had a two-channel output setup, you could have E, A, and D strings going to one side, and G, B, and E to the other. Or you could have E and A going to one, the middle two strings muted, and the B and E going to a different channel.” Each output has a 3-position switch, which toggles between one of two channels, or mute.
“I’m just saying there’s some unexplored territory at the beginning of the signal chain. If you start looking inside your guitar, then it opens up a world of opportunities.” —Pete Roe
This all might seem a little overly complicated, but Roe sees it as a simplification. He says when most people think about their sound, they see its origin in the guitar as fixed, only manipulatable later in the chain via pedals, amp settings, or speaker decisions. “I’m not saying that’s wrong,” says Roe. “I’m just saying there’s some unexplored territory at the beginning of the signal chain. If you start looking inside your guitar, then it opens up a world of opportunities which may or may not be useful to you. Our customers tend to be the ones who are curious and looking for something new that they can’t achieve in a different way.
“If each string has its own channel, you can start to get some really surprising effects by using those six channels as a group,” continues Roe. “You could pan the strings across the stereo field, which as an effect is really powerful. You suddenly have this really wide, panoramic guitar sound. But then when you start applying familiar effects to the strings in isolation, you can end up with some really surprising textural sounds that you just can’t achieve in any other way. You can get some very different sounds if you’re applying these distortions to strings in isolation. You can get that kind of lead guitar sound that sort of cuts through everything, this really pure, monophonic sound. That sounds very different because what you don’t get is this thing called intermodulation distortion, which is the muddiness, essentially, that you get from playing chords that are more complex than roots and fifths with a load of distortion.” And despite the powerful hardware, the pickups don’t require any soldering or labor. Using a “nanosuction” technology similar to what geckos possess, the pickups simply adhere to the guitar’s body. Submarine’s manuals provide clear instruction on how to rig up the pickups.
“An analogy I like to use is: Say you’re remixing a track,” explains Roe. “If you get the stems, you can actually do a much better job, because you can dig inside and see how the thing is put together. Essentially, Submarine is doing that to guitars. It’s allowing guitarists and producers to look inside the instrument and rebuild it from its constituent parts in new and exciting ways.”
