Let’s have a deep look into what can be done to get rid of single-coil hum, which can be very annoying, especially when playing live. I’m sure you all know the situation: Your band managed to get an important Friday night gig at, let’s say, Bob’s Country Bunker. You and your bandmates arrive in time to set up your equipment, naturally with everything plugged into the same circuit as Bob’s popcorn machine, dishwasher, and sandwich maker. You plug in your Strat, turn up your amp, and there’s a loud humming noise coming out of it.
A single-coil pickup has one coil with six magnet rods and two bobbins holding everything together. It not only picks up the strings, but also all kinds of external magnetic fields generated by transformers and other electromagnetic devices. But when two coils are wound in opposite directions and are working together, the hum will get canceled. This is an old principle dating back to the beginning of the 20th century, and it’s how a humbucker pickup works. In the past, guitarists had to struggle with radio stations, fluorescent tubes, transformers, and the like; today, it’s more digital fallout and, of course, digital power supplies of all kinds.
The pickup industry created all kinds of hum-canceling pickups in single-coil shape, most commonly stacked and double-rail-style pickups. So, a humbucker pickup can be the ticket out of such unpleasant live situations. But all of these options generate a different magnetic field compared to a single-coil pickup, resulting in a different tone. The resonant frequency is shifted downwards a little bit because the ohmic resistance and inductance of the two coils are added together. The tone gets milder and warmer, with more midrange—you all know this tone. Splitting such a humbucker will sound more single-coil-like, but it will pick up hum again. Connecting both coils in parallel rather than in series will also sound more single-coil-like and is hum-canceling, but it’s not a real single-coil tone.
Using a reverse wound, reverse polarity (RWRP) pickup such as a Strat’s middle pickup will get you at least two hum-free switching positions (bridge+middle and neck+middle), but even this sounds different. Going active is another way to fight humming noises, and these special pickups sound more or less like a real single-coil, too.
But what if you don’t want to compromise? Is pure single-coil tone with no hum possible? Yes and no! It is possible to come close, but one day, a digital gremlin may find a way to annoy you to a certain degree. And there are extreme situations where only a humbucker will work.
One step in the right direction is shielding the pickups and cavity of your guitar. Shielding the compartment of a guitar the right way is a challenge on its own, and I will cover this in a future installment of this column. But even if all the shielding is done the right way, the sound of the pickup will be altered to a certain degree, which is the nature of the beast. And the shielding is always there, so you can’t switch between pure single-coil and shielded single-coil tone.
So, what about switchable hum-canceling for your guitar? This way you could have both: pure single-coil tone and hum-free operation when needed. And if this could not only be made switchable but also controllable, you could balance your tone between the two.
Here is a solution based on principles from Bill Lawrence, which my dear friend Bernd C. Meiser from the BSM company has refined in order to make it more controllable: a variable dummy coil.
“But what if you don’t want to compromise? Is pure single-coil tone with no hum possible? Yes and no!”
In simple terms, a dummy coil is an additional pickup that is identical to the other pickups but without magnets. It has a phase, but no polarity. A dummy coil accepts the electric signal created by the magnetic single-coil pickup and reverses it, which will remove a large portion of the hum. In the process, a very small amount of the treble signal is lost as well. However, this treble loss is far less compared to stacked or dual-rail humbuckers.
The specs of the dummy coil need to be close to the pickup you are complementing. So, any universal dummy coils advertised to work with all single-coil pickups will only work to a certain degree but not perfectly. Instead, it’s best if you order a dummy coil that matches your pickup. The company who made your pickup will know the formula, and a dummy coil from them will be super effective. If that pickup is from a larger manufacturer, you’ll need to find out specific parameters—wire gauge, wire type, number of turns—so a custom pickup company can make a matching dummy coil for you.
The simplest way to set up a dummy coil would be to connect it permanently, so it’s 100 percent active all the time. For more flexibility, you can add a switch to turn the dummy coil on and off. But the most flexible way is to use a pot to control the dummy coil, so you can dial in pure single-coil tone, 100 percent dummy-coil hum-removing, and everything in between—in other words, so you can balance tone and hum-free-ness depending on the certain playing situation.
To do so, connect a 0.01 uF capacitor in parallel to the dummy coil. The high-end frequencies will no longer pass the dummy coil and its inductance; they will be drained low-resistance to ground. For the bass frequencies, the capacitor is still high-resistance so the dummy coil is active. This way you will have humbucking functionality for the bass frequencies, but pure single-coil tone in the high frequencies—what a perfect and clever solution from Bill Lawrence. If you now connect the capacitor and the dummy coil to a pot, you have a controllable dummy coil as described above.
You can experiment with the capacitor value for fine-tuning your system; 0.01 μF is a pretty good value to start. With a smaller cap, you shift the humbucking effect toward the high frequencies and vice versa. A smaller cap means more overall humbucking (bass and highs) and a larger cap means less overall humbucking, with the high and middle frequencies staying untouched.
A Stratocaster is perfect for this mod because it has two tone controls. One will be converted to a Telecaster-style master tone control, while the other will become the new dummy-coil controller.
For a Stratocaster with three vintage flavored single-coil pickups, I recommend the following pot configuration (all audio taper): 250k volume, 500k tone, 500k dummy-coil controller. This way, in humbucking mode, the two coils are connected in series rather than in parallel, so the resonance peak will be dampened. The two 500k pots will help compensate for this. The 250k volume is always the way to go in a passive guitar system to ensure the best and most even control. The 500k tone pot can be a little bit over the top in pure single-coil mode, but simply roll it down a little and you are in the 250k ballpark—problem solved!
Here we go for the wiring. It’s not hard to do and mostly uses the parts that are already there:

As one of the lead guitarists of Slayer, the outspoken, opinionated King has also bred snakes off and on since the late ’80s.
Covid helped shape the foundation of King’s musical future, because the pandemic inadvertently created a luxury he’d rarely experienced before: time. Rather than feeling inconvenienced by the delays, he homed in on elements of his craft in ways he’d never done before, and the resulting album and his solo debut, From Hell I Rise, became his hammer.
“The pandemic really shaped the sound and the performance on this record,” says King. “It gave us some flat tires at first, because Paul [Bostaph, drums] and I both caught Covid, and it took a while for us to get back in the saddle.”
Bostaph had already digested so much of the material by the time they dove back into recording that it became a real game changer compared to how they’d worked together previously in Slayer. “It was the first [project working together where] he heard all the lyrics before he recorded, and he heard all the leads except one or two. It’s the most prepared he ever was, and being so familiar with it made it that much easier for me to play what I wanted to play.”

King is a cofounding member of Slayer and arguably one of the most instantly recognizable and well-respected thrash metal guitarists of his generation. Over nearly 40 years, he has pioneered some of the most brutal and revolutionary guitar riffs ever created in the genre. His singular use of the tremolo—pulling up more than pressing down—and the multiple tunings that pepper the band’s catalog, from D# to C# to B, are just two of the attributes that set King apart from his contemporaries. He also wrote or cowrote some of Slayer’s most incendiary songs, including “Mandatory Suicide,” “Repentless,” “Hell Awaits,” “Disciple,” and “Raining Blood.”
With Slayer—who have announced reunion dates for September 2024, five years after the group’s official terminus—King lays claim to six RIAA gold certifications, one multi-platinum plaque, and five Grammy nominations with two wins in the category of Best Metal Performance for the songs “Eyes of the Insane” and “Final Six,” both off of the Christ Illusion album.
“[My solos are] usually an afterthought, and the last thing to get done. This time everything was thought out [beforehand] and not just thrown in there.”
Known for his allegiance to the Las Vegas Raiders NFL football team, his love of snakes, and his taste for Jägermeister, King is outspoken, opinionated, and authentic. The self-proclaimed “metal kid” famously takes himself a little too seriously for some. But the real testament to his seriousness lies within his attention to detail, and the songcraft on From Hell I Rise, as well as the time he and Bostaph spent refining the material during the pandemic, is demonstrative of his commendable work ethic.

Every note seems intentional, every beat meticulously composed, yet all of it played with a spontaneity that belies its years-long incubation period. Having almost all of his solos worked out by the time he went into the studio was a refreshing approach. “They’re usually an afterthought,” he admits, “on the back burner, and the last thing to get done. This time everything was thought out [beforehand] and not just thrown in there.”
From Hell I Rise is a decisive musical statement from a man on a mission, out to prove himself after the then-apparent demise of one of thrash metal’s “Big Four,” and was eventually spurred on by a furious two-week recording session at Henson Recording Studios in Los Angeles. Featuring a band that also includes bassist Kyle Sanders (Hellyeah), guitarist Phil Demmel (Machine Head), and vocalist Mark Osegueda (Death Angel), the record rages with intensity—real musicians playing real metal in real time. In an era when technology can often smooth the edges off the human element on recordings, From Hell I Rise features fire-breathing performances from musicians who clearly honed their craft long before the crutch of technology was made available. And even though it has an intangible, nostalgic vibe to it, make no mistake, it is not some relic from the bygone past, but rather a bristling, modern-sounding tour de force.
“If you’ve ever liked any Slayer throughout any part of our history, then there’s something on this record that you’ll get into.”
From the opening salvo of “Diablo,” an instrumental call to arms that harkens back to early ’80s Iron Maiden, to the first single, “Idle Hands,” a fast, aggressive track that highlights King’s deft, articulate approach to rhythm guitar, to the detuned manic riffing in the title track, From Hell I Rise runs the gamut from classic punk to thrash to straight-up old-school heavy metal. Familiar topics, including religion and war, abound. Herculean speeds are achieved. King says the album is heavy, punky, doomy, and spooky. “If you’ve ever liked any Slayer throughout any part of our history, then there’s something on this record that you’ll get into.”
Part of the X factor on From Hell I Rise comes courtesy of producer Josh Wilbur (Korn, Lamb of God, Avenged Sevenfold, Bad Religion). King says Wilbur grasped his lead guitar sound better than anyone he’s worked with in the past. “It’s a hard thing to duplicate if you’re not standing in front of it in a live environment,” he attests. “Whatever Josh did in his mixing and mastering, it’s the closest to my live sound I’ve ever heard. I know it’s a weird adjective, but it’s really fat and ominous. I’m super happy with it.”
For From Hell I Rise, King took a new approach by planning out his solos in advance of the album’s recording.
Reigning Phoenix Music cofounder Gerardo Martinez was responsible for suggesting Wilbur to King. “We had a meeting down in Southern California,” he recalls. “I wanted to make sure I could respect the guy because if I don’t respect the guy, I’m not going to play it 10 times if he asks me to. I want somebody that will tell me to do that if I need to, and I’ll listen to him.” He says Wilbur is a wizard in the studio who brought intensity and energy to the recording sessions.
King doesn’t tinker much with his rhythm tone in the studio from song to song. He’s more of a set-it-and-forget-it kind of guy. “We just go for the main rhythm because there’s not a whole lot of things that need my sound to change,” he explains. “If it’s a spooky song or something that needs a different vibe, I’ll mess around with it. But I’m going for the home run. I’m going to set my tone and roll with it.”
“Whatever Josh [Wilbur] did in his mixing and mastering, it’s the closest to my live sound I’ve ever heard. I know it’s a weird adjective, but it’s really fat and ominous.”
King is a bona fide “super old-school” guitarist and runs through a very meat-and-potatoes signal chain for his rhythm tone. He goes from his Marshall JCM800 2203KK signature amp to Marshall MF400B Mode Four speaker cabinets with “a guitar right in front of it.” That’s it. No frills to the core. His self-assessed “primitive” approach also applied to the demos he sent to Bostaph in the early stages of writing the new album—he has no home studio to speak of. “I’m playing out of an amp that’s about as big as my boot and recording it on my phone,” he admits. “It’s deceptive how decent that sounds.”

Live, King runs three of his signature amps and staggers the speaker cabinets—head one will go to cabinets one and four, head two goes to cabinets two and five, and head three goes to cabinets three and six. In this setup, the heads are not powering the cabs directly below them in a column. “I really love it because I’ve got a wash of all three heads at once,” he explains.
Due to his writing style, there’s also not a whole lot of space for effects in his guitar sound. “There’s not room for things like delay, because it’s very precise,” he says. His rhythm playing is a cornerstone of his brand, and much like James Hetfield with Metallica and Scott Ian with Anthrax, he plies his trade by executing flawless, intricate rhythms at breakneck speeds. The secret he says, is all in the wrist. “A lot of people don’t know that they don’t need to play from the elbow,” he explains. “If you want any kind of speed and you want to be articulate, you’ve got to play from the wrist. You’ve got to have as minimal movement as you can.” The elbow, he explains, is too far from the pick to be the appropriate hinge for speed. “If your action is coming from your wrist, you’ve got a lot more control over the speed and the articulation. That’s how it’s got to be if you want to play this kind of music.”
“I wanted to make sure I could respect the guy because if I don’t respect the guy, I’m not going to play it 10 times if he asks me to.”
King has historically paired himself with equally capable guitarists: first Jeff Hanneman, then Gary Holt, and now Demmel. He says that he’s never had to adjust his playing style to any of them, but does note what differentiates Holt and Demmel from Hanneman, and how that affects his live performances. “I had to learn to not listen to Gary and Phil because they’re a lot more melodic than Jeff was,” he assesses. “And I don’t mean that in a detrimental way. It’s just that Jeff had his style. Gary is super melodic, and I think Phil’s even a bit more melodic.” Shifting his focus from listening to what the other guitarist is doing so he can pay attention only to what he’s playing has become King’s superpower when playing live.

The addition of Sanders on bass has, however, pricked up King’s ears and facilitated an adjustment on his part, albeit in the demoing and recording phase of music making. “Early on, I sent Kyle four songs with no bass just because I didn’t want to influence him, even though I’m totally capable of playing bass on a record or on demos,” he attests. “I’m like, ‘If I’m going to let this guy play bass, let’s let him come up with something.’ Maybe it’s something I wouldn’t think of because I’m a guitar player. I’m not a bass player.” Within two days, Sanders sent back the same four tracks with bass. King was blown away. “I’ve never had anybody that into playing bass—it was very refreshing for me. So every time I sent him demos, I sent him bass-free ones.”
“I just play stuff until I find something that has a strong chorus, intro, or verse rhythm. Then I try to find some friends that make it a better song, and go from there.”
King moved to New York after Slayer called it quits in 2019. Now, when he goes back to Southern California to rehearse, he gets a rental car with SiriusXM radio, and has since gone through “a real big Ritchie Blackmore renaissance,” he shares. “Man, Deep Purple was so good. Blackmore was a madman. And that band was a supergroup. I mean, [keyboardist] Jon Lord, [drummer] Ian Paice; regardless which singer you’re talking about, there’s so much talent in that band. It took me a minute to go back and realize it and now I’m like, ‘How did I not like this more [when I was younger]?’” King, perhaps influenced by this “supergroup” concept, certainly assembled an A-list cast of musicians for From Hell I Rise.
Despite the musical pedigree Bostaph, Demmel, Osegueda, and Sanders bring to his first solo album, one can’t help but wonder if King’s criteria for bandmates has as much to do with camaraderie as it does skillset. “I put a lot of songs together in ’20 and ’21,” he attests. “I just play stuff until I find something that has a strong chorus, intro, or verse rhythm. Then I try to find some friends that make it a better song, and go from there.”
