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!

Orange Gain Baby 100
orangeamps.com
Playing through a 100-watt head is immensely satisfying, regardless of your style. If you want dirty, and there’s a gain control, you’ve got dirty. If you want clean, the headroom hits the sky. Whether you’re purveying rock ’n’ roll filth, snarling blues, old-school roots, or avant-skronk, it’s all there—especially if you use pedals for low-gain drive and color.
In the case of Orange’s new Baby series entries, these possibilities exist in triplicate: the compact, highly controllable Gain Baby 100, Tour Baby 100, and Dual Baby 100 amps. These grab-and-go solid-state units with strong metal chassis are a mere 6 1/2 pounds, come with a durable shoulder bag for transport, and can be dropped atop a cabinet or into a rack. (These amps measure 12.8" x 3.13" x 7.68".) Each model has two radically different channels, guaranteeing versatility, plus a class A/B power stage for clarity and heavy lifting. They all offer the fat, midrange growl and the fast touch-sensitivity I associate with the classic, Orange sounds of players ranging from Peter Green to Slipknot’s Jim Root, which is perhaps a result of their single-ended JFET preamp stage.
I tested these Babies with a vintage Les Paul, a PRS Silver Sky SE, and a Zuzu custom with coil-splitting, to get a wide variety of tones. I also switched between a 1x12 cabinet with a G 12M Greenback and another with a 50-watt Eminence Red Coat Private Jack. Both cabs were 8 ohms, but the amps can also run 70 watts into 16 ohms. While the Celestion drilled down on nasty, Hendrix- and early ’70s-era voicings, the 50-watter really let the amps breathe in lush harmonic detail.
Each of the triplets has a footswitch option for channel and volume switching, an effects loop, and a balanced XLR out, and can be easily used with a DAW, cab sims, and IR captures. These units can also be switched for 100, 110, and 220 volts AC. Short take: I found a lot to like about these sonic siblings.
Gain Baby 100
While I’m not typically a high-gain player, I took to the Gain Baby 100 immediately, enjoying the edgy tone, responsiveness, sustain, and articulation in its dirty channel. Dirty offers gain, volume, presence, and 3-band EQ, plus the footswitchable volume has its own level control, and it delivers a stinging rock voice where chords hang and bloom. This channel’s real “dirty” secret is a toggle that can be flipped to “tight” mode, which functions like an additional EQ stage that polishes lows and focuses the mids, making them really singing and dimensional.
I initially viewed the clean channel on the Gain Baby and Tour Baby as pedal platforms, with just a volume control and bass and treble, but the clean side’s built-in, single-knob compressor pushes the Gain Baby’s volume and low-end character to the fore, conjuring memories of that ’70s uber-beast, the Sunn Beta Lead (and the Melvins’ King Buzzo). Ultimately, the Gain Baby 100 delivers very distinct and appealing bookends of heavy for just under 600 bucks.
Key: Dirty channel rhythm > dirty channel rhythm with tight switch engaged > dirty channel lead > dirty channel with tight switch lead > clean channel rhythm > clean channel lead
Tour Baby 100
The road-oriented Tour Baby seems the most versatile of the trio. The dirty channel has the same control panel as the dirty side of the Gain Baby, minus the tight switch. And while overall the amp seems to have a bit less gain, it’s still easy to get into Wayne Kramer territory by cranking up the gain control when you want to kick out the jams. Sweet, sustained tones were a snap to achieve by dialing back the guitar’s tone pots, riding the amp’s mid control high, setting treble to about 7 or 8, and dialing in the bass at 3.5 to 4. And, again, like the Gain Baby, the 3-band EQ offers plenty of range. If even more crunch is desired, the presence knob helps dial it in.
The Tour Baby’s clean channel also mimics the Gain Baby’s clean setup, but the compressor doesn’t lean into the low end like it does on the Gain Baby. It does, however, sculpt and define tones in a very appealing way, warming and pushing midrange. While I preferred the dirty channel here, my colleague Tom Butwin fell for the clean side, and his excellent demo video online is well worth watching. For me, this amp’s strength is that it stands on its legs and growls from the dirty side, and provides a characterful pedal platform on the clean side. All three amps, by the way, sound terrific with a reverb pedal, though less so at higher-gain settings.
Dual Baby
For players devoted to traditional British voicings, the Dual Baby may be the most enticing option, providing at least two recognizably classic sounds in one small, efficient package. Channel A is based on the company’s Rockerverb series, minus the reverb, and both A and B channels on the Dual Baby have 3-band EQ. The B side has the same setup and tonal characteristics as the dirty channel of the Tour Baby, sans the footswitchable volume, so you can’t pump up the level for solos with a quick stomp. However, it does have a “tight” toggle, so it’s easy to get into the same spanking, airy terrain as the Gain Baby’s dirty side or play it relatively clean.
But the A channel has another asset: a “tubby” switch, which is new for Orange. With gain pushing toward 7 and presence at about midway, and the treble rolled back, the tubby setting’s low-end boost evokes Black Sabbath—dark and ominous and perfect for sustained power chords. If your tastes run toward nasty, there’s a lot to like with the Dual Baby.
Key:
Channel A rhythm > channel A lead > channel A rhythm tubby > channel A lead tubby >
Channel B rhythm > channel B lead > channel B rhythm tight > channel B lead tight
The Verdict
Orange’s three versatile Babies cover a lot of ground in small, very affordable, well-built packages. Their response and rich-hued sounds–available even at low volumes–never left me pining for tubes, and their 100-watts make them useful for any stage. For travel, studio, or at-home playing, they are well worth investigating. These Babies can unquestionably run with the big boys. PG

Pre-CBS Fender Stratocasters have long held the mystique and imagination of Fender’s biggest fans. By early 1964, Fender had started to build their Strat® pickups with gray flatwork, and these gray bottom pickups were known for a notably punchy sound and higher output. Finding a pre-CBS Strat® with these rare pickups can be a challenge.
However, as Joe Bonamassa discovered, sometimes looking beyond a guitar’s originality can lead to uncovering a truly exceptional example. Joe’s 1964 Stratocaster® started its life with a three-tone sunburst finish and stock gray-bottom pickups, but was refinished with a unique “Greenburst”, which instantly captivated Joe. With the powerful sounding pickups, great playability, and striking look, Joe knew it was “an instant star”.
Lucky for guitar players everywhere, Joe Bonamassa has once again collaborated with the Seymour Duncan Custom Shop to offer the magic sound of one of his favorite instruments through a new set of signature gray bottom Strat® pickups. The Joe Bonamassa “Greenburst” Stratocaster® Set is made with period-correct wiring and staggered alnico 5 magnets. The gray bottom flatwork is pad printed with Joe’s signature, and the first 500 sets will be aged, and include limited edition packaging and a certificate of authenticity signed by Joe and Seymour W. Duncan.
Fans of Joe Bonamassa have seen the Greenburst Strat® light up the stage on tour with Joe, and now the powerful sound of “the coolest, most hideous guitar” in Joe’s collection can be attained in a Strat® of your own.

In honor of Paul Reed Smith's birthday today, PRS launches a limited-edition model of Paul's personal instrument.
Introduced on Smith’s birthday, February 18, the Charcoal Phoenix Limited Edition is part of the PRS Guitars 40th Anniversary celebration. Only 150 of these instruments will be available worldwide, with each including a 40th Anniversary certificate hand signed by Paul Reed Smith himself.
"When we released the Private Stock John McLaughlin Limited Edition in 2023, I was inspired by its exceptional sound and playability. For the Charcoal Phoenix, I wanted to create something equally remarkable but with a stoptail bridge," said PRS Guitars Founder & Managing General Partner, Paul Reed Smith. "Using chaltecoco for the neck and ziricote for the fingerboard, I achieved an instrument that sustains beautifully and rings with clarity. The deep crimson back and the charcoal microburst top inspired the name ‘Charcoal Phoenix,’ evoking the imagery of a phoenix rising from fire and ashes.”
Over the past year, Smith has road-tested this guitar, refining its design and tone. Most recently, he played this model on stage at the late-January 2025 PRS Guitars 40th Anniversary concert at the House of Blues in Anaheim. A deep crimson back contrasts with the Private Stock-grade figured maple top in a charcoal microburst finish. The ripple abalone “Old School” bird inlays on the ziricote fingerboard add a vintage touch.
The Charcoal Phoenix also features the PRS TCI pickups, newly updated for 2025, and EQ mini-toggle switches. The TCI pickups are crafted with American Alnico magnets and slightly modified winding, wiring and electronics specifications. Based on Smith’s experience playing this guitar live and in the studio for more than a year, these pickups offer clear tones from spanky single coils to full soapbars. The EQ mini-toggles act as tuned high-pass filters when engaged, removing shelved low end and allowing the high frequencies through for more clarity and musical highs.
Rounding out the details are the PRS Stoptail bridge and PRS Phase III Non-Locking Tuners. The bridge is engineered with curved string slots, brass inserts and steel studs. It is designed to maximize the transfer of the strings’ vibrations through the guitar. The lightweight tuners promote tone transfer for a louder, more resonant instrument.
PRS Guitars is planning a year full of new product introductions. Stay tuned to see new gear and 40th Anniversary limited-edition guitars throughout the year at www.prsguitars.com/40 and by following @prsguitars on Instagram, Tik Tok, Facebook, X, and YouTube.
