“Modern guitars for modern times,” is a fitting mission statement for Jeff Kosmoski’s KOZM Guitars. One glance at any of his ergonomic instruments and it’s quickly apparent that the luthier isn’t interested in producing modern-day versions of guitars that came on the scene 50-plus years ago.
The self-taught builder is a mechanical engineer with a background in product design and computer-aided design (CAD). He’s played guitar since grade school but didn’t always want to be a luthier. “The idea of actually making my own guitar seemed kind of strange,” he says. “Why spend the time making your own guitar, when you can just buy one and let you focus on the main task—creating new music?”
About six years ago, however, Kosmoski was working at a company with a number of guitarists, some of whom were into kit guitars and making their own bodies. It got Kosmoski thinking: If he could use his background and skills with modern 3-D CAD tools to design and build any guitar he could imagine, what would he come up with?
Some boutique luthiers pride themselves on not using CNC for valid reasons, but Kosmoski embraces the technology for his builds because it allows him to create the instruments he envisions. That is, modern, curvaceous guitars that leave the past behind by moving away from flat, 2-D guitar design rooted in 1950s technology. “Yes, there will always be those who say the old ways are the best ways,” says Kosmoski. “At the end of the day, however, the important question is, ‘Can you make the material do what you want it to do?’ If your vision is limited by your tools, maybe it’s time to try new tools.”
Kosmoski’s isn’t influenced by a specific designer or instrument manufacturer per se, but he does have a design modus operandi. “In general, I’m inspired by people who aren’t afraid of shattering paradigms, people who think way outside the box—Salvador Dali, Jimi Hendrix, Frank Zappa, Nikola Tesla.” He considers Les Paul a visionary and says, “I’m pretty sure that if he was just coming on the scene today, he’d be using CAD and a computer-controlled router to design and build guitars.”
Kosmoski builds both electrics and acoustics, and doesn’t necessarily have a model he considers his signature or one he’s most pleased with. “To be honest, I’m more interested in my next guitar design—to see what I can come up with and to see how it’s going to sound,” shares the builder. “Although I like building electrics, these days I’m more intrigued with the possibilities in the acoustic guitar realm. In some ways, I’m just scratching the surface of what’s possible. There’s a lot of room in the design space of 3-D, ergonomic, organic acoustic guitars.” Kosmoski contends happy with the way his acoustics sound so far, but added, “I’m eager to see how far I can modify the sound by altering the body geometry, the size and location of the sound holes, the stiffeners, wall thicknesses, and woods.”
“Guitar players are an interesting breed,” says the luthier. “In a realm that’s all about breaking the mold, moving forward, and being innovative, I’m intrigued that so many guitarists feel obliged to reach for the guitars of yesterday. Most builders today are confined to the world of flat. However, the human body isn’t flat. Nor is the natural world in general. I strive to make my guitars as ergonomic, organic, non-flat, and seductive as possible.”
Pricing and Availability
Kosmoski is currently only selling direct through his website, but hopes to have some of his acoustic models in Portland, Oregon, guitar stores soon. The base price for his guitars is $2,395 for the acoustics and $2,595 for the electrics, and Kosmoski highly encourages customer involvement in the build process. “Because I don't start making the guitar until everything is designed on the computer, I have the ability to take screen images of the design, and email them to the customer,” says Kosmoski. “My CAD software also lets me play with colors and details, so if the customer doesn't like something, we can manipulate the design until we get it right.”

The Jesus Lizard’s sixth album, Blue, served as the band’s final statement from the frontlines of noisy rock for the next 26 years. By the time of their dissolution in 1999, they’d earned a reputation for extreme performances chock full of hard-hitting, machine-like grooves delivered by bassist David Wm. Sims and, at their conclusion, drummer Mac McNeilly, at times aided and at other times punctured by the frontline of guitarist Duane Denison’s incisive, dissonant riffing, and presided over by the cantankerous howl of vocalist David Yow. In the years since, performative, thrilling bands such as Pissed Jeans, METZ, and Idles have built upon the Lizard’s musical foundation.
Denison has kept himself plenty busy over the last couple decades, forming the avant-rock supergroup Tomahawk—with vocalist Mike Patton, bassist Trevor Dunn (both from Mr. Bungle), and drummer John Stanier of Helmet—and alongside various other projects including Th’ Legendary Shack Shakers and Hank Williams III. The Jesus Lizard eventually reunited, but until now have only celebrated their catalog, never releasing new jams.

Back in 2018, Denison, hanging in a hotel room with Yow, played a riff on his unplugged electric guitar that caught the singer’s ear. That song, called “West Side,” will remain unreleased for now, but Denison explains: “He said, ‘Wow, that’s really good. What is that?’ And I said, ‘It’s just some new thing. Why don’t we do an album?’” From those unassuming beginnings, the Jesus Lizard’s creative juices started flowing.
So, how does a band—especially one who so indelibly captured the ineffable energy of live rock performance—prepare to get a new record together 26 years after their last? Back in their earlier days, the members all lived together in a band house, collectively tending to the creative fire when inspiration struck. All these years later, they reside in different cities, so their process requires sending files back and forth and only meeting up for occasional demo sessions over the course of “three or four years.”
“When the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.” —Duane Denison
the Jesus Lizard "Alexis Feels Sick"
Distance creates an obstacle to striking while the proverbial iron is hot, but Denison has a method to keep things energized: “Practice loud.” The guitarist professes the importance of practice, in general, and especially with a metronome. “We keep very detailed records of what the beats per minute of these songs are,” he explains. “To me, the way to do it is to run it to a Bluetooth speaker and crank it, and then crank your amp. I play a little at home, but when the time comes to get more in performance mode, I have a practice space. I go there by myself and crank it up. I turn that amp up and turn the metronome up and play loud.”
It’s a proven solution. On Rack—recorded at Patrick Carney’s Audio Eagle studio with producer Paul Allen—the band sound as vigorous as ever, proving they’ve not only remained in step with their younger selves, but they may have surpassed it with faders cranked. “Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style,” explains Allen. “The conviction in his playing that he is known for from his recordings in the ’80s and ’90s is still 100-percent intact and still driving full throttle today.”
“I try to be really, really precise,” he says. “I think we all do when it comes to the basic tracks, especially the rhythm parts. The band has always been this machine-like thing.” Together, they build a tension with Yow’s careening voice. “The vocals tend to be all over the place—in and out of tune, in and out of time,” he points out. “You’ve got this very free thing moving around in the foreground, and then you’ve got this very precise, detailed band playing behind it. That’s why it works.”
Before Rack, the Jesus Lizard hadn’t released a new record since 1998’s Blue.
Denison’s guitar also serves as the foreground foil to Yow’s unhinged raving, as on “Alexis Feels Sick,” where they form a demented harmony, or on the midnight creep of “What If,” where his vibrato-laden melodies bolster the singer’s unsettled, maniacal display. As precise as his riffs might be, his playing doesn’t stay strictly on the grid. On the slow, skulking “Armistice Day,” his percussive chording goes off the rails, giving way to a solo that slices that groove like a chef’s knife through warm butter as he reorganizes rock ’n’ roll histrionics into his own cut-up vocabulary.
“During recording sessions, his first solo takes are usually what we decide to keep,” explains Allen. “Listen to Duane’s guitar solos on Jack White’s ‘Morning, Noon, and Night,’ Tomahawk’s ‘Fatback,’ and ‘Grind’ off Rack. There’s a common ‘contained chaos’ thread among them that sounds like a harmonic Rubik’s cube that could only be solved by Duane.”
“Duane’s approach, both as a guitarist and writer, has an angular and menacing fingerprint that is his own unique style.” —Rack producer Paul Allen
To encapsulate just the right amount of intensity, “I don’t over practice everything,” the guitarist says. Instead, once he’s created a part, “I set it aside and don’t wear it out.” On Rack, it’s obvious not a single kilowatt of musical energy was lost in the rehearsal process.
Denison issues his noisy masterclass with assertive, overdriven tones supporting his dissonant voicings like barbed wire on top of an electric fence. The occasional application of slapback delay adds a threatening aura to his exacting riffage. His tones were just as carefully crafted as the parts he plays, and he relied mostly on his signature Electrical Guitar Company Chessie for the sessions, though a Fender Uptown Strat also appears, as well as a Taylor T5Z, which he chose for its “cleaner, hyper-articulated sound” on “Swan the Dog.” Though he’s been spotted at recent Jesus Lizard shows with a brand-new Powers Electric—he points out he played a demo model and says, “I just couldn’t let go of it,” so he ordered his own—that wasn’t until tracking was complete.

He ran through various amps—Marshalls, a Fender Bassman, two Fender Super-Sonic combos, and a Hiwatt Little J—at Audio Eagle. Live, if he’s not on backline gear, you’ll catch him mostly using 60-watt Blackstar HT Stage 60s loaded with Celestion Neo Creambacks. And while some boxes were stomped, he got most of his effects from a Line 6 Helix. “All of those sounds [in the Helix] are modeled on analog sounds, and you can tweak them endlessly,” he explains. “It’s just so practical and easy.”
The tools have only changed slightly since the band’s earlier days, when he favored Travis Beans and Hiwatts. Though he’s started to prefer higher gain sounds, Allen points out that “his guitar sound has always had teeth with a slightly bright sheen, and still does.”
“Honestly, I don’t think my tone has changed much over the past 30-something years,” Denison says. “I tend to favor a brighter, sharper sound with articulation. Someone sent me a video I had never seen of myself playing in the ’80s. I had a band called Cargo Cult in Austin, Texas. What struck me about it is it didn’t sound terribly different than what I sound like right now as far as the guitar sound and the approach. I don’t know what that tells you—I’m consistent?”

"When a guitar is “the one,” you know it. It feels right in your hands and delivers the sounds you hear in your head. It becomes your faithful companion, musical soulmate, and muse. It helps you express your artistic vision. We designed the Les Paul Studio to be precisely the type of guitar: the perfect musical companion, the guitar you won’t be able to put down. The one guitar you’ll be able to rely on every time and will find yourself reaching for again and again. For years, the Les Paul Studio has been the choice of countless guitarists who appreciate the combination of the essential Les Paul features–humbucking pickups, a glued-in, set neck, and a mahogany body with a maple cap–at an accessible price and without some of the flashier and more costly cosmetic features of higher-end Les Paul models."
Now, the Les Paul Studio has been reimagined. It features an Ultra-Modern weight-relieved mahogany body, making it lighter and more comfortable to play, no matter how long the gig or jam session runs. The carved, plain maple cap adds brightness and definition to the overall tone and combines perfectly with the warmth and midrange punch from the mahogany body for that legendary Les Paul sound that has been featured on countless hit recordings and on concert stages worldwide. The glued-in mahogany neck provides rock-solid coupling between the neck and body for increased resonance and sustain. The neck features a traditional heel and a fast-playing SlimTaper profile, and it is capped with an abound rosewood fretboard that is equipped with acrylic trapezoid inlays and 22 medium jumbo frets. The 12” fretboard radius makes both rhythm chording and lead string bending equally effortless, andyou’re going to love how this instrument feels in your hands. The Vintage Deluxe tuners with Keystone buttons add to the guitar’s classic visual appeal, and together with the fully adjustable aluminum Nashville Tune-O-Matic bridge, lightweight aluminum Stop Bar tailpiece, andGraph Tech® nut, help to keep the tuning stability nice and solid so you can spend more time playing and less time tuning. The Gibson Les Paul Studio is offered in an Ebony, BlueberryBurst, Wine Red, and CherrySunburst gloss nitrocellulose lacquer finishes and arrives with an included soft-shell guitar case.
It packs a pair of Gibson’s Burstbucker Pro pickups and a three-way pickup selector switch that allows you to use either pickup individually or run them together. Each of the two pickups is wired to its own volume control, so you can blend the sound from the pickups together in any amount you choose. Each volume control is equipped with a push/pull switch for coil tapping, giving you two different sounds from each pickup, and each pickup also has its own individual tone control for even more sonic options. The endless tonal possibilities, exceptional sustain, resonance, and comfortable playability make the Les Paul Studio the one guitar you can rely on for any musical genre or scenario.

Grissom and Paul Reed Smith’s first collaboration appeared in 2007 in the shape of theGrissom DGT—a signature instrument that’s seenmany iterations since. His Custom 30 amplifier followed five years later. But at 30 watts, that amp is pretty powerful for a lot of folks. So, this year PRS and their lead amp designer, Doug Sewell, unveiled the more club-friendly, tremolo-equipped DGT 15.
The basic architecture of the Indonesia-built DGT 15—single-channel, 2 x EL84 power section, 15 watts, and onboard reverb and tremolo—bears more than a little resemblance to a few important ’60s combo amps. But its 3-band EQ with presence, top-cut, and bright boost controls lends a lot of additional functionality and flexibility without cluttering the control panel or the playing experience. And, unlike some classic amps in this power class, the DGT 15 generates its wallop from a pair of output tubes in cathode bias, driven by three 12AX7s and one 12AT7 in the front end.
Feature Length
If the DGT 15’s control set were made up of just the EQ, presence, and top-cut controls, it would offer impressive tone-sculpting power. But the 3-way bright, boost, and master volume switches add exponentially more colors and gain contrasts. The bright switch is clever. It can be switched to always-on mode or set to disengage when the boost is on. The footswitchable boost, meanwhile, gives the single-channel DGT-15 the flex of a two-channel amp with a lead mode. Better still, you can set the amp up so you can activate the boost and master volume together—enabling access to the most headroom with the boost off and keeping the gain from running wild when the boost is engaged. The tremolo, too, can be activated via a mini-toggle or the included footswitch.
“While it’s basically clear, round, and full, depending on where you set the powerful EQ controls, you can reshape those tones into chunky, chiming, or sparkly variations on the clean theme.”Because the DGT-15 is cathode biased, the output tubes require no re-biasing when you change them. But the back panel includes jacks for monitoring bias levels, which is handy for matching tubes or diagnosing possible issues. The back panel is also home to the 5-pin DIN footswitch jack and three speaker outs for various combinations of 4 ohm, 8 ohm, or 16 ohm cabs. Our test unit came with the ported-back PRS DG 1x12 cabinet, which is loaded with one 60-watt Celestion Vintage 30. The DGT 15 head itself is a little bigger than lunchbox-sized (unless you’ve got a particularly hefty appetite). But it’s still an easy load at just 17.25" x 9" x 9.25" and a hair under 20 pounds. The 1x12" cab is relatively compact too, at 24" x 22.18" x 10.5", and weighs 27 pounds.
Tejas Tone!
If you read only the specs for the DGT 15 (or never had the pleasure of playing a Custom 30), you’ll probably expect a British voice. But the DGT 15’s core tonality leans as much toward the 1960s black-panel Fender camp, and it has a ready-to-rumble personality that shines through whether you match it to an ES-355 or a Telecaster.
With Fender single-coils in the mix, non-boosted settings are very clean right up to around 3 o’clock on the volume, where the amp starts to edge into breakup just a little. That’s a lot of clean room to roam. But while it’s basically clear, round, and full, depending on where you set the powerful EQ controls you can reshape those tones into chunky, chiming, or sparkly variations on the clean theme. Humbuckers push the DGT 15 to juicier, crunchier zones much sooner, of course. Even so, the amp remains crisp and taut without going muddy. With both single-coils and humbuckers, the overdrive and saturation generated by the boost avoid the sizzly sounds you hear from many modern lead channels and overdrives. It’s also very dynamic—easing into light distortion when you pick hard, and shedding its aggressive edge when you use a light touch or reduce guitar volume. Overdrive pedals (in this case, a Klon-like Wampler Tumnus Deluxe, Marshall-style Friedman Small Box, and a multi-voiced Tsakalis Six) gel with both the boost and clean modes, too. The reverb and tremolo are superb. The range of both successfully spans subtle and more radical sounds—and between these, a couple of drive pedals, and the Boost function, a gigging guitarist can wrangle a lot of flexibility out of this amp.
The Verdict
Using the single-channel, 2 x EL84/reverb/tremolo architecture as a jumping-off point, the DGT 15 scales new heights of versatility—not just via flexible switching and tone-shaping power, but by melding Vox-y edge with Fender clarity and body at a very accessible price.
Phat Machine
The Phat Machine
The Phat Machine is designed to deliver the tone and responsiveness of a vintage germanium fuzz with improved temperature stability with no weird powering issues. Loaded with both a germanium and a silicon transistor, the Phat Machine offers the warmth and cleanup of a germanium fuzz but with the bite of a silicon pedal. It utilizes classic Volume and Fuzz control knobs, as well as a four-position Thickness control to dial-in any guitar and amp combo. Also included is a Bias trim pot and a Kill switch that allows battery lovers to shut off the battery without pulling the input cord.
Silk Worm Deluxe Overdrive
The Silk Worm Deluxe -- along with its standard Volume/Gain/Tone controls -- has a Bottom trim pot to dial in "just the right amount of thud with no mud at all: it’s felt more than heard." It also offers a Studio/Stage diode switch that allows you to select three levels of compression.
Both pedals offer the following features:
- 9-volt operation via standard DC external supply or internal battery compartment
- True bypass switching with LED indicator
- Pedalboard-friendly top mount jacks
- Rugged, tour-ready construction and super durable powder coated finish
- Made in the USA
Static Effectors’ Street Series pedals carry a street price of $149 each. They are available at select retailers and can also be purchased directly from the Static Effectors online store at www.staticeffectors.com.
