1950s gibson les paul
Ever been frustrated by how the two volume controls interact on a dual-humbucker axe? Here’s how to make them work independently.
Here's an easy but effective mod for Les Paul slingers that solves a problem they've been living with since the model's introduction more than a half century ago. This project also applies to most other guitars with dual humbuckers, individual master volume and master tone knobs for each pickup, and a 3-way pickup selector switch.
The problem (or not).
The Les Paul circuit dates back to the mid '50s. It has changed slightly over time—Gibson used several different tone caps and experimented with tone-pot wiring—but essentially, modern Les Pauls employ the original wiring.
The Les Paul circuit dates back to the mid '50s. It has changed slightly over time—Gibson used several different tone caps and experimented with tone-pot wiring—but essentially, modern Les Pauls employ the original wiring.
One thing Gibson did not change was the concept of coupled volume pots. You know how this works: With an independent pair of controls for each pickup and a 3-way toggle switch, you can dial in your lead volume and tone using the bridge pickup, set up a rhythm tone using the neck pickup, and then quickly change from lead to rhythm and back using the 3-way switch. This works great—two preset sounds at your fingertips.
Les Paul players know what happens when you use the middle position of the 3-way switch: Backing down just one of the volumes to zero shuts off the entire guitar.
But Les Paul players know what happens when you use the middle position of the 3-way switch: The pickups are wired together in parallel, so when both pickups are engaged, rolling down the volume of one even slightly while leaving the other fully open makes the latter much louder than its mate. Even worse, backing down just one of the volumes to zero shuts off the entire guitar.
Why is this? Because the two volume controls are not decoupled, they interact. With a passive circuit like this, it's just the nature of the beast. Consequently, the dual-humbucker world divides into two opposing camps: The first doesn't consider this interaction a problem. It's simply part of the game—get used to it. The other camp regards this interaction as a system error and tries to eliminate it.
Now, the only real solution for this problem—assuming it's an issue for you—is to switch to active circuitry. All other "solutions" are compromises that may or may not appeal to you. You must let your ears decide.
Swap it out.
It's easy to wire a Les Paul so the volume controls work independently: You simply wire the volume pots backwards. (This is how some Rickenbacker guitars and early Fender Jazz basses are wired.)
Wiring diagram courtesy of singlecoil.com.
First, study the wiring diagram shown here. It represents the modern factory wiring typically found in Les Pauls. The black wires are ground; the white wires are the hot connections from the pickups and to the output jack. The black wires that run from pot to pot form the "ground bus." Be careful not to close this ring—leave the connection between the two volume pots open, as shown in the wiring diagram, otherwise you'll create a perfect antenna that picks up all kinds of funny noises. (For a noise-free circuit, it's very important that the ground bus uses a solid, not too thin wire and strong soldering spots.)
Now, simply interchange connections 3 and 2 on both volume pots, including the tone cap connections. That's it! Leave all connections on the tone pots untouched. You've now wired both volume pots backwards, thus decoupling them.
Time to network?
There's a big downside to this mod: When the pickups are wired backwards, they "see" less resistance, and the output impedance rises. This results in dramatic treble loss when you roll back the volume. It's an idiosyncrasy of passive guitar systems: When you turn down the volume, even just a bit, treble loss is not proportional: A small cut in volume creates a far greater loss in treble response. And the treble loss is even worse when the volume pots are wired backwards.
You can combat this by adding a treble-bleed network between the input and output of each volume pot. This usually consists of a small capacitor, often with a resistor in series or parallel. Simply solder the treble-bleed network between lugs 3 and 2 on each volume pot and see if it sounds right to you.
As far as capacitor and resistor values, that depends on how much treble you like. Some people prefer using a capacitor only (aka "treble bypass cap"), while others like a cap with a resistor in parallel. A useable range for the cap is from 220 pF to 680 pF; a resistor wired in parallel can range from 150k ohm to 330k ohm. A popular choice for a cap-only solution is 330 pF. For a network solution, many players like a 470 pF cap with a 330k-ohm resistor wired in parallel. You could start with this and see what sounds best to you. Small silver mica caps sound excellent for this mod.
Remember, passive circuitry can never add anything that isn't already there, but it can reshape the tone by deemphasizing certain frequencies, which makes others more prominent. This treble-bleed network filters bass so the highs are more pronounced.
Until next time, keep on modding!

Does the guitar’s design encourage sonic exploration more than sight reading?
A popular song between 1910 and 1920 would usually sell millions of copies of sheet music annually. The world population was roughly 25 percent of what it is today, so imagine those sales would be four or five times larger in an alternate-reality 2024. My father is 88, but even with his generation, friends and family would routinely gather around a piano and play and sing their way through a stack of songbooks. (This still happens at my dad’s house every time I’m there.)
Back in their day, recordings of music were a way to promote sheet music. Labels released recordings only after sheet-music sales slowed down on a particular song. That means that until recently, a large section of society not only knew how to read music well, but they did it often—not as often as we stare at our phones, but it was a primary part of home entertainment. By today’s standards, written music feels like a dead language. Music is probably the most common language on Earth, yet I bet it has the highest illiteracy rate.
Developed specifically for Tyler Bryant, the Black Magick Reverb TB is the high-power version of Supro's flagship 1x12 combo amplifier.
At the heart of this all-tube amp is a matched pair of military-grade Sovtek 5881 power tubes configured to deliver 35-Watts of pure Class A power. In addition to the upgraded power section, the Black Magick Reverb TB also features a “bright cap” modification on Channel 1, providing extra sparkle and added versatility when blended with the original Black Magick preamp on Channel 2.
The two complementary channels are summed in parallel and fed into a 2-band EQ followed by tube-driven spring reverb and tremolo effects plus a master volume to tame the output as needed. This unique, signature variant of the Black Magick Reverb is dressed in elegant Black Scandia tolex and comes loaded with a custom-built Supro BD12 speaker made by Celestion.
Price: $1,699.
“I’m a fan of the riff,” says Jerry Cantrell. “I’m always collecting ideas, and you never know when they’re going to come, or what they’re going to turn into
The 6-string wielding songwriter has often gotten flack for reverberating his classic band’s sound in his solo work. But as time, and his latest, tells, that’s not only a strength, but what both he and loyal listeners want.
The guitarist, singer, and songwriter Jerry Cantrell, who is best known for helming Alice in Chains, one of the most influential bands in hard-rock history, is an affable, courteous conversationalist. He’ll apologize, for instance, when he’s been on a PR mission all afternoon and needs to eat something. “I’m sorry. I’m starving. I’m going to make a BLT while we finish this interview,” he says on a recent Zoom call.
“That’s bacon frying, by the way,” he adds, in case his interviewer was wondering about the sizzling sound in the background.
Over the better part of an hour, only a couple of points of discussion seem to stoke his ire. One would be ’90s-era culture writers who felt compelled to brand a wide range of interesting bands from the same city (Seattle) with the same hollow tag (grunge). “It’s just a fucking label,” he says. “But I get it. You gotta have a fucking descriptor.” (When he gets miffed, or especially enthusiastic, Cantrell’s F-bombs can progress from steady punctuation to military fusillade.)
Another pet peeve: Those who seem bewildered by the fact that his solo work often evokes Alice in Chains. “It always trips me out,” he says, “when I hear comments or get questions all the time, like, ‘Well, this sounds like Alice.’ Well, what do you think it was going to sound like? I’m the guitar player and the songwriter of Alice. That’s what I do. Do you want me to not be myself? It’s just a bizarre, bizarre thing.” A big laugh follows.
“I’m always collecting ideas, and you never know when they’re going to come, or what they’re going to turn into. I look at it like depositing money in a bank.”
Cantrell, 58, has a right to feel irked by such exchanges. After all, he and the classic Alice lineup of vocalist Layne Staley, bassist Mike Starr, and drummer Sean Kinney invented a mesmeric, instantly identifiable sound that continues to stand alone in heavy music. On paper, the Alice formula doesn’t indicate multi-platinum success outright: off-kilter vocal harmonies shared between Staley and Cantrell, which can call to mind arcane American folk music or the classical avant-garde; parts written in odd time; lyrics about the most wrenching depths of drug addiction, a black cloud that followed the band throughout its ascent and tragically claimed Staley’s life in 2002 and Starr’s in 2011.
But Cantrell and Alice were also dedicated students of hard-rock history, who, along with their Seattle peers Soundgarden, helped to reinvent chart-topping metal for the alternative-rock era. To be sure, the guitarist ranks among the great riff maestros, and his solos, whether all-out wailing or comprised of a few bluesy bends, always had weight and meaning within the context of the song. And with all due respect to Extreme, no other hard-rock act explored acoustic music with more brilliant results.
Boasting nine tracks and coproduced by Cantrell and Joe Barresi, I Want Blood keeps the guitarist’s expert riffs and lyrical solos front and center.
On their masterpiece, the 1992 album Dirt, Alice in Chains managed to take Black Sabbath’s template for molten riffs into stranger, more artful, and more desperate territory, yet they also crafted tracks chock-full of hooks. A seamless meld of pop moves and bone-crushing heaviness is something of a holy grail for hard-rock songwriters and producers, and Dirt nabs it. Think of tracks like “Them Bones,” with its 7/8 intro riff and aslant vocal-harmony verses that resolve into a punchy, satisfying chorus—among the pithiest assessments of mortality in rock ’n’ roll. Or “Rooster,” an homage to Cantrell’s Vietnam-veteran father, with its left-field R&B harmonies and molasses-drip tempo. Somehow, these are songs that can rattle around in your brain throughout entire road trips or workdays; as of this writing, Dirt has sold five-million copies in the U.S.
“Let the players find their songs, and the songs find their players.”
Cantrell’s new album, I Want Blood, is his fourth solo release, and it’s a strong argument that he should continue to sound like himself and his legacy. Coproduced by Cantrell and hard-rock studio wizard Joe Barresi, its nine tracks tap into the Alice in Chains aesthetic in a way that will hit a sweet spot for longtime fans. As on the albums that Alice has released since Staley’s passing, with vocalist William DuVall, that indefinable sense of unease, that smoky ambiance of dread, isn’t so enveloping. But Cantrell’s most crucial gifts—the riff science, the knack for hooks, the belief that solos should be lyrical, musical, singable—are front and center, and razor-sharp.
What’s more, he’s recruited fellow hard-rock royalty to fulfill this vision. In addition to Barresi, whose credits comprise Kyuss, Melvins, Tool, QotSA and many, many others, the album’s personnel includes bassists Robert Trujillo and Duff McKagan, and drummers Mike Bordin (Faith No More) and Gil Sharone (Marilyn Manson, the Dillinger Escape Plan).
Through Alice in Chains’ rise in the early ’90s to recent years, Cantrell’s hard-rock presence has remained unshakeable. Here, he strikes a timeless rock 'n' roll pose.

I Want Blood is a ripper. “Vilified” couples a chunky metal riff with wah and talk-box accents and a wandering, Eastern-tinged melody; “Off the Rails” matches a line à la John Carpenter’s Halloween score with a groove-metal thrust, before a radio-ready chorus kicks in. Ditto the chorus of “Let It Lie,” whose verse riff is pure Sabbath bliss. The earworm title track is the stuff music-sync-licensing dreams are made of. When he dials the tempo back toward ballad territory, as on “Echoes of Laughter,” “Afterglow,” or “It Comes,” Cantrell’s instinct for songcraft seems to get even stronger. As with Alice’s best LPs, I Want Blood stays with you and grows on you until it’s in steady rotation.
So what of that songcraft? It’s been over three decades since Cantrell debuted on record, and he’s still mining heavy gold. What’s the strategy, and what’s the secret? Does Cantrell’s work get harder or easier as he edges toward 60? “There’s a duality to it,” he says. “So in one way, I can answer that it’s pretty easy for me to make music. And then also, it’s fucking incredibly difficult to make something good. It can be both.”
He details the three-part work cycle that has defined his adult life: “There’s the demo process of writing. There’s the preproduction and actual recording of a record. And then there’s the period where you go out and tour it, along with all your other material, in a set. During that last third of the process, I’m really not writing, but through all the phases I’m always collecting riffs.” He’s also continually listening to great music, and allowing it to seep in. In the previous week, Cantrell says, he’d “rocked a bunch of Bad Company, UFO, AC/DC, some Maiden, some Hank Williams, some Ernest Tubb, some ‘Jungle Boogie.’”

“I’m a fan of the riff,” he adds. “I’m always collecting ideas, and you never know when they’re going to come, or what they’re going to turn into. I look at it like depositing money in a bank. Like if I’m in a dressing room somewhere and I’m just warming up, and I see [one of my bandmates] react to something that I’m playing—put it in the bank. If I have a superpower, it is being able to hear something that might be a cool thing to work up and develop into a full-on song.
“When I’m slugging out riffs and just jamming out, if it feels good to rock out and your head starts moving and your foot starts tapping and you got something good—you know. It’s got to hit on a primal level first, and satisfy in that way.”
Writing, then, is often the more cerebral duty of assembling the best of what Cantrell has accrued and documented. “Like Lego pieces,” he says. “That used to be one of my favorite toys when I was a kid—Legos. Building stuff, block by block.” But, Cantrell points out, the process can also be more straightforward; he’ll start with a single riff and attempt to build the song’s infrastructure out from there, “throwing options at it, and ideas,” he says.

“I don’t necessarily know where I’m going a lot of the time. I just know that I have an intention to get there, and I’ve been able to take that journey to completion and make some pretty decent albums and songs over the years. And so I have the confidence to know that I probably can do this again—if I just put my mind to it and go through the process and work my ass off in concert with a group of people who have the same thought process.”
“There should always be the threat that the train is going to come off the rails.”
Cantrell is most certainly a “band” guy. For I Want Blood, he decided to play through a bunch of the material with his famous friends in preproduction, rather than simply assigning them one or two songs to guest on: “Let the players find their songs, and the songs find their players,” as he puts it. “It might’ve been with a little bit of frustration, because they got day jobs in some pretty impressive bands.” Time wasn’t exactly plentiful, but he did get in some living-room jams and other sessions with Trujillo, Bordin, and McKagan that ensured each track had its best possible lineup. Fortunately, Cantrell’s coproducer, Barresi, is similarly averse to cutting corners. Cantrell describes him as “a long-haul trucker” who “doesn’t suffer fools.”
“I’m an architect who is also a builder. You know what I mean?” says the guitarist, alluding to the relentless, often tedious work of record-making.“There should always be the threat that the train is going to come off the rails,” he says. For both men, Cantrell explains, “When you’re done with the record is when you think you couldn’t have done it any better.” Or, as Barresi likes to say, “How do you know you’ve gone too far unless you’ve already been there?”
Barresi also has a kind of encyclopedic recall of rock sonics. “He’s a guy who knows where all the bodies are buried,” Cantrell says, “and any combo of stuff you want to achieve: ‘Like, you know that song in The Departed, the Stones tune where it sounds like the guitar is going through a Leslie?’ [“Let It Loose,” off Exile on Main Street.] ‘Yeah, I know that pedal, man. Let’s grab it.’ You give him a reference and he knows how to replicate it.”
“I love working with a lot of different colors,” Cantrell says. “So I’ll use any guitar or any amp or any pedal to get a certain sound, and that all comes with experimentation. But it always starts with the basics.”
“When you’re done with the record is when you think you couldn’t have done it any better.”
If you’re a faithful reader of Premier Guitar, you may already know what that means: two mid-’80s G&L Rampages and the Les Paul Custom that Cantrell relied on to write his 2002 solo album Degradation Trip (the instrument with the custom blowtorch finish job). In amps, his go-to was the Bogner Fish preamp that he immortalized in Alice in Chains, in addition to his Friedman JJ-100 signature head. Cantrell also mentions the Bogner-modded Marshall sound he’s known for—aka the fabled Snorkeler—alongside tones from Orange and Laney. Among the guitars that made the cut: a butterscotch Les Paul Junior that was a gift from Billie Joe Armstrong a couple years back. When asked about effects, picks, and strings, Cantrell responds that he’s “a Dunlop guy”—which includes his MXR Jerry Cantrell Firefly Talk Box and Dunlop signature Cry Baby wah pedals.

Live at the Grammy Museum in Los Angeles in 2021, Jerry Cantrell testifies to his status as one of the most iconic guitarists in hard-rock history.
Cantrell is a fount of anecdotes, and talking guitar is a great way to hear some of them. He first saw the Rampage onstage in a club, after moving from Washington to Dallas, Texas, in the mid-’80s. Later, he began jamming with some guys who played Rampages, and picked up a job at a music shop that their father managed. The shop was a G&L dealer, so Cantrell paid for his instruments in part by working there. The Rampage, he adds, “just felt right.”
“The guy who built the necks and bodies that Eddie used to build his guitars was right in my backyard.”
“You gotta give a lot of credit to Eddie Van Halen,” he adds. “[The Rampage] was basically Leo Fender’s answer to Frankenstein, to the Charvel/Jackson model. One tremolo, one knob, one humbucker; that’s it. No-nonsense, just a meat-and-potatoes rock ’n’ roll guitar.”
A few years before the Rampage—Cantrell pinpoints 1979, because Van Halen II was out—he obtained a neck that was originally intended for EVH, and used it on a Strat he built himself in woodshop. The neck was payment from Boogie Bodies, the legendary guitar-parts manufacturer where Lynn Ellsworth and Jim Warmoth laid the foundation for the Superstrat era. “That shop was in Puyallup, Washington,” Cantrell says, “and I lived in Spanaway, which was right next door.The guy who built the necks and bodies that Eddie used to build his guitars was right in my backyard.”
Cantrell was barely in his teens when he got a gig helping out around the shop, and earned a “beautiful bird’s-eye maple neck” that didn’t make it to Eddie because it had a small divot in the 3rd fret. Cantrell recalls today that his duties included sweeping up sawdust. Then, as now, it was all about the work.
