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!

Empress Effects is proud to announce the release of the Bass ParaEq, a bass-specific parametric EQ pedal.
Building on the success of their acclaimed ParaEq MKII series, which has already gained popularity with bassists, the Bass ParaEq offers the same studio-grade precision but with features tailored for bass instruments.
Basses of all types – including electric and upright basses with active and passive electronics – can benefit from the Bass ParaEq’s tone-sculpting capabilities.
The new pedal follows the success of the Empress Bass Compressor and ParaEq MKII Deluxe, which have become some of the company’s best-reviewed and top-selling products. The Bass Compressor’s popularity confirmed what Empress had long suspected: bassists are eager for tools built with their needs in mind, not just adaptations of guitar gear.
The Bass ParaEq retains the line’s powerful 3-band parametric EQ and studio-style features while introducing a bass-optimized frequency layout, a selectable 10MΩ Hi-Z input for piezo-equipped instruments, a dynamically-adjusted low shelf, and automatic balanced output detection—perfect for live and studio use alike.
The Bass ParaEq also offers an output boost, adjustable by a dedicated top-mounted knob and activated by its own footswitch, capable of delivering up to 30dB of boost. It’s perfect for helping your bass punch through during key moments in live performance.
Whether dialing in clarity for a dense mix or compensating for an unfamiliar venue, the Bass ParaEq offers precise tonal control in a compact, road-ready form. With 27V of internal headroom to prevent clipping from even the hottest active pickups, the Bass ParaEq is the ultimate studio-style EQ designed to travel.
Key features of the Bass ParaEq include:

The veteran Florida-born metalcore outfit proves that you don’t need humbuckers to pull off high gain.
Last August, metalcore giants Poison the Well gave the world a gift: They announced they were working on their first studio album in 15 years. They unleashed the first taste, single “Trembling Level,” back in January, and set off on a spring North American tour during which they played their debut record, The Opposite of December… A Season of Separation, in full every night.
PG’s Perry Bean caught up with guitarists Ryan Primack and Vadim Taver, and bassist Noah Harmon, ahead of the band’s show at Nashville’s Brooklyn Bowl for this new Rig Rundown.

Primack started his playing career on Telecasters, then switched to Les Pauls, but when his prized LPs were stolen, he jumped back to Teles, and now owns nine of them.
His No. 1 is this white one (left). Seymour Duncan made him a JB Model pickup in a single-coil size for the bridge position, while the neck is a Seymour Duncan Quarter Pound Staggered. He ripped out all the electronics, added a Gibson-style toggle switch, flipped the control plate orientation thanks to an obsession with Danny Gatton, and included just one steel knob to control tone. Primack also installed string trees with foam to control extra noise.
This one has Ernie Ball Papa Het’s Hardwired strings, .011–.050.
Here, Kitty, Kitty
Primack runs both a PRS Archon and a Bad Cat Lynx at the same time, covering both 6L6 and EL34 territories. The Lynx goes into a Friedman 4x12 cab that’s been rebadged in honor of its nickname, “Donkey,” while the Archon, which is like a “refined 5150,” runs through an Orange 4x12.
Ryan Primack’s Pedalboard
Primack’s board sports a Saturnworks True Bypass Multi Looper, plus two Saturnworks boost pedals. The rest includes a Boss TU-3w, DOD Bifet Boost 410, Caroline Electronics Hawaiian Pizza, Fortin ZUUL +, MXR Phase 100, JHS Series 3 Tremolo, Boss DM-2w, DOD Rubberneck, MXR Carbon Copy Deluxe, Walrus Slo, and SolidGoldFX Surf Rider III.
Taver’s Teles
Vadim Taver’s go-to is this cherryburst Fender Telecaster, which he scored in the early 2000s and has been upgraded to Seymour Duncan pickups on Primack’s recommendation. His white Balaguer T-style has been treated to the same upgrade. The Balaguer is tuned to drop C, and the Fender stays in D standard. Both have D’Addario strings, with a slightly heavier gauge on the Balaguer.
Dual-Channel Chugger
Taver loves his 2-channel Orange Rockerverb 100s, one of which lives in a case made right in Nashville.
Vadim Taver’s Pedalboard
Taver’s board includes an MXR Joshua, MXR Carbon Copy Deluxe, Empress Tremolo, Walrus ARP-87, Old Blood Noise Endeavors Reflector, MXR Phase 90, Boss CE-2w, and Sonic Research Turbo Tuner ST-200, all powered by a Voodoo Lab Pedal Power 2 Plus.
Big Duff
Harmon’s favorite these days is this Fender Duff McKagan Deluxe Precision Bass, which he’s outfitted with a Leo Quan Badass bridge. His backup is a Mexico-made Fender Classic Series ’70s Jazz Bass. This one also sports Primack-picked pickups.
Rental Rockers
Harmon rented this Orange AD200B MK III head, which runs through a 1x15 cab on top and a 4x10 on the bottom.
Noah Harmon’s Pedalboard
Harmon’s board carries a Boss TU-2, Boss ODB-3, MXR Dyna Comp, Darkglass Electronics Vintage Ultra, and a Voodoo Lab Pedal Power 2 Plus. His signal from the Vintage Ultra runs right to the front-of-house, and Harmon estimates that that signal accounts for about half of what people hear on any given night.
