This month we’re going to talk about recording with omni microphones. Often ignored due to their wide polar pattern and general misinformation, their use in capturing great guitar sounds should not be overlooked. Let’s first examine what omni means and then see how their application might help you cut better tracks.

Sometimes called “pressure microphones,” omni mics measure sound pressure at a fixed point in space. Since it’s not concerned with direction, an omni can often be placed where other types would not work. Also, many omni microphones (such as DPA and Earthworks) have very small capsules that are amazingly natural sounding with an even frequency response curve (the DPA 4007 is virtually flat from 20Hz to well above 20kHz). In reality, the commonly used cardioid microphone is completely coloring your sound – which may or may not be right for your application.
In addition, omni microphones don’t suffer from proximity effect, which is the boosting of low frequencies as you get closer to the source. They can also handle some huge sound pressure levels, or SPLs, with certain models taking up to 155dB before overloading. While most of us will never record anything that loud, they can take it when you deliver it.
So now that you have some basic fun facts about omnis, how can you use them? Well, since they record equally in all directions, placing one on an acoustic guitar will also capture some of the room sound, for example. That in turn leads to a more natural sounding recording of the instrument. Of course, the better the room, the better the
overall sound.
Often, when I use my Earthworks QTC-1 [now renamed the QTC40] mic on a guitar, the playback comments are along the lines of “now that’s what my guitar sounds like to me!” To an engineer capturing an acoustic instrument, that’s music to my ears. Another great application of omni microphones is to combine them with a cardioid type. When recording Al DiMeola playing his late-thirties Martin, I often used a pair of cardioid Schoeps in an XY configuration directly in front of the guitar, with another pair of the above mentioned Earthworks omnis just outside the Schoeps, about two to three feet away and four feet apart.
The Schoeps provided the closeness and tight sound while the Earthworks delivered the ambient, open sound. By adjusting the fader volumes of each pair and panning them creatively on the console, the true tone of the instrument was captured – with very little EQ’ing.
You don’t have to use pairs of mics to get a great sound with an omni. I often record flamenco guitarist Romero using a single Earthworks and a Royer ribbon mic. The Earthworks is placed near the 12th fret of his instrument, with the Royer capturing the body of the guitar. This combination yields a dark, warm tone from the Royer and a bright, transient sound from the Earthworks. Also, the snap of the instrument is captured in the room (which is mostly wood) by both the figure-8 pattern of the Royer and the omni pattern of the Earthworks.
Omni microphones also sound great on things like acoustic bass, piano, strings and as room microphones for percussion and drums. I’ve used them to re-record submixed string sections in a live studio by pumping the mix of strings into the room through speakers and mic’ing them. This provides a dimensional sound that cannot be duplicated by the actual close miking of the instruments themselves.
High-end omni microphones are often used to capture symphonic performances, since they properly translate the ambient sound of acoustic venues. I’ve even used them with great results to capture vocals – with the use of a pop screen, of course.
While omni microphones have many applications, it’s their use on acoustic guitars that keeps me coming back for more. With their ability to capture a clean, clear tone, a wide dynamic range and the natural sound of an instrument, they make a great choice when you’re looking for something different in the studio.

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?”

Galloup’s Plek tech Adam Winarski preps a Yamaha acoustic for the machine.
Presently, many certified guitar-repair specialists possess the expertise required to deliver an instrument that both sounds and plays wonderfully. The standards set by manufacturers and distributors have significantly risen, safeguarded by rigorous quality protocols to guarantee the best possible acoustic experience for customers. Additionally, lutherie training has raised the bar for critical processes, and one of the most tricky is fretwork.
Traditional fretwork once involved manual labor, with technicians utilizing sandbags or similar supports to steady the neck as they straightened it with a truss rod during the filing process. A notable advancement in this field came in the mid 1970s when Don Teeter, an author and repair expert, imposed a new method: fixing the guitar body to the bench and using blocks to maintain the neck in a playing position. This refinement was one of many in the continued quest to produce superior instruments by standardized methods.

In the late 1970s, another pivotal innovation was introduced by Dan Erlewine. He created an advanced fret jig with a specialized body-holding system and neck supports, adding another layer of precision to the repair process. During my collaboration with Dan in 1985, we developed a rotating neck jig that counterbalanced the forces of gravity, keeping the instrument in its playing orientation while adjusting the neck supports. This step represented a significant leap in establishing control and standardization of fretwork procedures in our industry. By 1986, our approach had evolved into a freestanding workstation coupled with a sophisticated hold-down mechanism and enhanced neck supports, culminating in increased accuracy, efficiency, and consistency. Over the decades, the Erlewine/Galloup rotating neck jig has become a benchmark in numerous shops, enhancing fretwork performance.
"This step represented a significant leap in establishing control and standardization of fretwork procedures in our industry."
By the 1990s, automated and computerized technologies permeated the guitar manufacturing and repair sectors. Initially applied by import companies in the mass production of guitars, the technology, although expediting processes, did not immediately achieve high execution standards. However, the tech dramatically improved over time, with computer-driven systems eventually transforming the industry. Contemporary automated production utilizing such advancements meets exceedingly high standards of precision. Some bespoke guitar manufacturers, such as Steve Andersen, were pioneers in adopting these methods, but it was companies like Taylor that established them in the modern era.
Inevitably, the progression of technology extended beyond the mere production of parts. Around 1995, German engineer Gerd Anke envisioned the integration of computer-assisted technology into enhancing instrument playability, giving rise to Plek technology, which uses computers to precisely measure and analyze the various components of a guitar, like neck relief, fret height, nut and bridge specs, and more. Nashville guitar-repair tech Joe Glaser was among the first to recognize the machine’s value, followed by San Francisco luthier Gary Brawer. When Heritage Guitar Inc. invested in a Plek machine, the guitar industry could no longer disregard the significance of this innovation.
“The machine’s scanning data confirmed that there was one nature of an ideal fret plane, done by hand or machine, and unsurprisingly, it conformed exactly to what physics predicts, not personal mojo.”
In the spring of 2022, Galloup Guitars obtained its first Plek machine. Promptly, our technician Adam Winarski paved the way for the Plek’s integration in our shop. Now, it’s a rarity for an instrument to leave our shop without having undergone Plek analysis and machining. Impressed by the results of our integration, we created “Intro to Plek” as a course for all students enrolled at the Galloup School of Lutherie, offering our students a practical introduction to this technology. We furthered this educational initiative with a comprehensive one-week intensive “Plek Certification Training Course” for both students and the public. This advanced Plek course serves those seeking to boost their knowledge base and employability in this high-precision field.
Plek is rapidly becoming an industry standard for major manufacturers and smaller shops alike. However, this does not mean that those without access to this technology cannot execute proficient fretwork. Personally, I continue to use my Erlewine/Galloup neck jig—not only out of nostalgia, but also because it remains an excellent method for delivering accurate and reliable guitars. Still, it’s undeniable that the process of fretting, fret dressing, and analytics of fretted instruments has undergone significant transformation, resulting in better sounding—and playing—guitars. And ultimately, that’s what it’s all about.
