Our goal is not to be overly technical here in terms of the exact circuit employed, but more to outline some of the more interesting points of its history and, where necessary, use other known Dumble circuits to try and create a timeline of sorts. As the current owner of these amps is a long time friend and client, I have had the opportunity to play, study, feed, and care for these amps many times over the years. It was fun, interesting, and challenging for me to be charged with trying to find out just what it was that we had here as far as history is concerned. There are few amplifiers that have shared the same shroud of mystery as the Dumbles.
At this juncture, I would like to take a moment to point out that Dumble amplifiers are handmade and are often “tuned” to the prospective player’s needs and desires. This is not unique to Dumble amps, and should be typical for any custom builder worth his or her salt. This is important to keep in mind because this results in many variations between amps. Variations can also be attributed to the natural development of a builder’s circuits and abilities—basically, it can be hard to pin down.
With that said, this is what we believe to be true.
Alexander Dumble was living on Jackson Browne’s property during the time that this amp was constructed for Browne (In fact, the original wooden channel switching footswitch still bears his name). The amp was originally constructed as an OD-100WR and it has most certainly been modified and updated over the years. The current owner speculates that these updates were made because it was close by and a convenient “guinea pig” for Mr. Dumble to try out new circuit design ideas.
The preamp circuit most likely began as (what’s known in internet circles) the “classic” preamp. This is based on other OD circuits built around the same time period. What we do know is that it does not have the classic pre in it now. Poring over my own notes and schematics as well as speaking with colleagues that have had experience with these circuits over the years, we decided that it probably has a very early version of the “skyline” pre, though the tone stack more closely resembles one of earlier examples. Could this be the first incarnation of this now famous design? The plate load resistors are not the earlier “low plate classic” design but a surprisingly current array. Some pretty interesting stuff going on in here.
The overall signal path is as follows:
Clean gain (Volume) > tone controls > the other gain stage > clean master Ratio (located on back) > two OD stages’ Gain and Level on front > OD Ratio (on back, tones are mostly bypassed in OD mode) > Reverb > Clean/Wet summing stage before the phase inverter, which is different from Fender circuits.
The current owner rightly brings up the fact that much of the magic seems to come from how you set and balance the “Ratio” controls on the back of the chassis.
This is all a gross simplification, of course! To go into great deal on this amp would require me to write a short novel on the topic. We could dedicate several articles on the choice of plate load resistors alone!
Another thing we discovered was that the combo cabinet and chassis were not necessarily intended to be used together. The story goes that the purple suede-covered 1x12 cabinet, complete with EVM-12L speaker and oval ported back panel, was offered to Bonnie Raitt to be used as a combo (with a head/chassis which is unknown to us) but was rejected as being too heavy. It then resided beside Mr. Dumble’s workbench serving as a coffee table of sorts until it was sold to Greg Bayles in 1989 (former owner of Make’n Music in Chicago) where it was mated with the OD-100WR chassis and sold to its current owner.
I will say that amongst all of the Dumble amps (and Dumble inspired clones) that I have spent time with, this definitely takes the cake! It has headroom, power, incredible touch sensitivity where one can go from clean cords to blistering single note runs with the energy of your picking hand. Truly superb! I’m a lucky man to have a job like this!

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
Last year’s Manning Fireworks was a breakout moment for Asheville, North Carolina’s MJ Lenderman, which is both the name of the band and the actual name of singer and guitarist Jake Lenderman, who also plays in the band Wednesday. The record topped plenty of year-end lists and drew favorable comparisons to the likes of Neil Young, Dinosaur Jr., and other stars of the pre- and post-’90s indie-rock boom.
On tour behind the record, the band stopped in at Birmingham, Alabama, joint Saturn on February 1. PG’s Chris Kies met up with Lenderman, guitarist Jon Samuels, pedal-steel player Xandy Chelmis, and bassist Landon George before the show to get the dirt on their dirt.
Brought to you by D’Addario.The SG
Lenderman’s main guitar these days is this 1979 Gibson The “SG,” which he bought in Birmingham while opening for Plains. It’s tuned to D standard, with Ernie Ball Beefy Slinky strings.
Do the Mascis Mash
It’s no surprise that Lenderman digs the Squier J Mascis Signature Jazzmaster. He’s a big Dinosaur Jr. fan and got to sit in with them in Los Angeles to play “In A Jar” in December 2024. From top to bottom, this one is tuned C–G–D–G–G–E for “You’re Every Girl to Me.”
Tele Time
This Fender American Vintage II 1977 Telecaster Deluxe comes out for cleaner needs in the set.
Original Jazz
This is Lenderman’s iconic 2008 Jazzmaster, which he bought back in Asheville.
Hi-Steppin'
Lenderman borrowed a Hiwatt to use at some hometown shows in Asheville and fell in love, so he brings this Custom 50 out on the road now. He’s working his way to a full J Mascis setup, “one cab at a time.”
MJ Lenderman's Board
Lenderman’s clean, easy board has a D’Addario tuner, Death By Audio Interstellar Overdriver Deluxe, a Dunlop wah which he uses as a subtle filter, and TC Electronic Flashback 2.
Loan from Lenderman
Lenderman recorded plenty with this Fender Player Telecaster, but now Samuels puts it to work
Hartzman's Hot Rod
Another loaner, this Hot Rod DeVille combo is on long-term borrow from Wednesday’s Carly Hartzman.
Jon Samuel's Board
Samuels’ board, which is a hybrid of his own pedals and even more borrowed units, carries a Hardwire HT-6 polyphonic tuner, Death By Audio Fuzz War, JHS Double Barrel, Dunlop wah, J. Rockett Archer Clean Boost, Joyo Tremolo, EHX Nano Small Stone, and TC Electronic Flashback 2.
Xandy's ZB
Chelmis, also a member of Wednesday, plays this 10-string ZB Custom, made in the early ’70s with a proprietary pickup. It stays in E9 tuning, and Chelmis makes it sing with a steel he bought from a pawn shop. It runs through a Fender Twin Reverb outfitted with a single 15", and a Goodrich H-120 volume pedal handles swelling duties. From time to time, Chelmis adds in a Guyatone SD2 sustainer for some fuzzy fun.
Precision Vision
George’s go-to is this 2006 Fender Mike Dirnt Precision Bass, strung with Ernie Ball medium-gauge flatwound strings.
Better Beta
George runs through a Sunn Beta Bass head into an Ampeg SVT810E cabinet.
Landon George's Board
On his board, George packs a Korg Pitchblack tuner, Origin Effects Cali76 Compact Bass, Boss DD-7, Darkglass Electronics Alpha Omega, and a Noble Amplifier Company utility box: It’s a tube preamp, DI box, and power supply, all in one.
“I’m a big fan of old things,” says Danny Worsnop. “From cameras to guitars to microphones to cars, I like the stories they tell and the lives they’ve lived. I think old stuff has more soul.”
Best known as the lead vocalist of rock bands Asking Alexandria and We Are Harlot, British-born Worsnop has also released two solo albums that explore country and blues. He’s currently in the studio working on his third solo release.
With his love of vintage aesthetics and appreciation for instruments that age with character, he’s spent much of his life searching for a guitar that feels like home. “I’m always on the quest to find the perfect thing,” he says.
For years, Taylor’s GS Mini-e Koa Plus has been his go-to songwriting companion. “I don’t need a bunch of things to do the job,” he explains. “This guitar was the first one that did that, and it’s been with me for years. The finish is beat up. It’s got shiny spots from the sweat on my arm. This has been my daily driver and workhorse and life partner since I got it. It’s more than a guitar. It has a life and a personality and a sound. You pick up any other GS Mini-e Koa Plus in the world, it doesn't sound like this one.”
With his love of older things, Worsnop acknowledges the challenges of making a deep connection with an out-of-the-box acoustic. “All the nice, shiny new guitars that anyone has sent me over the years are great—I have fun with them,” he says. “But I've never loved them. I find it hard to love new stuff because it kind of doesn't have a life or personality yet.”
Worsnop’s done his best to infuse them with some of his own personality by tweaking them in different ways–chasing a specific feel and sound that makes a guitar feel more like an extension of himself rather than just another utilitarian tool. But his most recent acoustic arrival was different.
“It’s more than a guitar. It has a life and a personality and a sound.”
Striking Gold
Worsnop recently got his hands on Taylor Guitars’ new Gold Label 814e, designed by Andy Powers, the creative visionary behind many of Taylor’s guitar innovations since 2011. For Taylor’s new Gold Label Collection, Powers drew inspiration from the sound of flattop acoustics from the 1930s and 1940s.
Worsnop was immediately drawn to the Gold Label 814e’s vintage-inspired visual aesthetic—influenced by old banjos and mandolins, early Taylor designs, and Powers’ pre-Taylor archtop guitars. But the true revelation came when he played it.
“When I saw this guitar... I mean, it looks super cool, like an older guitar,” he says. “And the second I picked it up, it was different. It was like, this plays like a guitar that is so old and has stories and songs in it already. I fell in love with it.”
Worsnop says that with other Taylors he has owned, including his GS Mini-e Koa Plus, he would often modify them in some way to give them a more vintage sensibility. But not with the Gold Label.
One of the defining features of the Gold Label 814e is its new Super Auditorium body shape. The non-cutaway body bears a clear family resemblance to Taylor’s popular Grand Auditorium, but the Super Auditorium is slightly longer and wider at the lower bout, with a slightly shallower depth. The new body dimensions, combined with Andy’s version of a long-tenon neck and his new fanned V-Class bracing pattern, are all key ingredients in a new sonic recipe that defines the sound of Taylor’s Gold Label collection. The result is a warm, old-heritage voice that’s unlike anything Taylor has ever produced.
Worsnop says the guitar complements him musically because it supports his dynamic vocals with extraordinary volume and responsiveness to a lighter touch.
“Because I sing loud, having something that’s loud enough, but not so loud that when I do drop down you can’t hear me anymore, is important for me,” he explains.
The Gold Label 814e comes with back and sides of solid Honduran rosewood or solid Hawaiian koa (Worsnop has the Honduran rosewood model) paired with a torrefied Sitka spruce soundboard. Each model is available with a natural or sunburst top.
The Revolutionary Action Control Neck™
One of the standout features of the Gold Label 814e is Taylor’s patented new Action Control Neck™, an innovative neck joint design that allows for quick, easy, and precise neck angle adjustments. It marks another step forward from the patented, micro-adjustable design Bob Taylor introduced back in 1999. Unlike traditional neck resets, this system, like Bob’s, is also glue-less, and in this case enables effortless fine-tuning on the fly without having to remove the neck or even the strings, and without the use of shims. By simply using a 1/4" nut driver (or standard truss rod wrench) on a nut in the neck block (accessible through the soundhole), a player can raise or lower the action to dial in an ideal setup.
“It is a massive deal,” says Worsnop. “When it comes to traveling musicians, it’s absolutely game changing. This allows you to do a micro-adjustment without having to get in the car and drive. When I’m in the studio, I like having that precision to be able to make it just perfect.”
For professional musicians, service techs, and recreational players who want to quickly fine-tune their action, the innovative neck design marks a paradigm shift.
In Studio and Onstage
In his Tennessee home, Worsnop has an upstairs studio where he records most of his music. It’s where he’s tested countless guitars, searching for the right fit. Though his trusty songwriting guitar has been the aforementioned GS Mini-e Koa Plus—perfect for capturing spontaneous new ideas—when it comes to recording, the Gold Label 814e has taken center stage.
“I’m working on the new album right now,” he shares. “If I’m at home and I’m just wandering around downstairs, which is usually where and how writing happens, [the GS Mini] is the guitar I’m walking around with. And then as soon as there’s an idea, I’ll go upstairs, and it’s the Gold Label. Honestly, I don’t play anything else up there now. I put the album recording on hold for this guitar. It’s the only guitar on the album.”
And it won’t just live in the studio. Worsnop plans to bring the Gold Label 814e on tour, making it his primary acoustic guitar for live performances.
Performance Highlight: "Ain't No Use"
In a recently recorded performance of his song “Ain’t No Use”, Worsnop showcases why the Gold Label 814e is such a great fit for him. The song, rich with storytelling and emotional depth, aligns well with the guitar’s vintage aesthetic and warm tonal character. It explores the universal tension between who we are and who we want to be, while emphasizing the transformative power of acceptance despite imperfections. The guitar’s deep, open sound and full-bodied, muscular tone are a perfect complement to Worsnop’s soaring, soulful vocals, amplifying the expressiveness of his performance and highlighting a symbiosis between player and instrument. A video of the performance is featured at the top of this article.
For Worsnop, the Gold Label 814e represents the culmination of years of searching, experimenting and refining his sound. It’s an instrument that feels like it has lived a life, carrying with it the soul and character he always craved in an acoustic.
“I have played music since I was 6 years old, and I’ve spent my entire life looking for my instrument,” he reflects. “At 34, I’ve found it.”
