Though he shook up the industry in 1993 with the Fly—the most unique solidbody design the electric world had seen in years—for more than 30 years now his primary passion has been advancing the art and science of archtop luthiery.
Though most players know Ken Parker because of the innovative guitar he and Larry Fishman designed and introduced under the Parker Guitars brand in 1993—the Fly—he has been obsessed with archtops for decades. Given the Fly’s striking ergonomics, composite-covered body, carbon-fiber fretboard, and proprietary, multifunction tremolo—all of which made it one of the most unique and successful new solidbody designs of the last 20 years—it should come as no surprise that Parker’s obsession is now advancing the art and science of archtop guitars. But that shouldn’t overshadow the fact that he does it all because he’s striving to inject the playing experience with real joy: “To me, if a guitar isn’t fun to play—if it doesn’t put a grin on your face and beckon you from the corner of the room—what is it for?”
To provide insight for this article, Parker sent a guitar for us to spend some time with and get the hands-on Parker archtop experience. The first touch is extraordinary. It’s featherlight and incredibly comfortable to hold. The neck is smooth, wide, easy to play, and devoid of anything that might create tension. When I played an Em chord, there was so much . . . everything—so much bass, so much liveliness, so much sustain. Everything we think the opposite of when we think archtop. And yet, it’s all archtop.
Though Ken Parker still uses the same headstock shape found on the Parker Fly, the simiarlities to his current archtop designs end there, and he no longer has a stake in Parker Guitars.
Clockwork
Parker trained as a toolmaker for a grandfather- clock making company before he started building guitars. “This beautiful guy kind of took me under his wing, because they didn’t have somebody to do all the tooling they needed—not the wooden parts, the metal parts. It was like going to grad school. I did four years worth of training in a year and a half.”
That training and facility for machining custom parts would play a vital role years later. Today, Parker handbuilds almost every piece of his archtops. “That is really a huge ingredient of who I am now—it was an incredible playground,” says Parker. “I was a sponge. It was just thrilling to me. I had dropped out of college, because I was studying philosophy and physics and I didn’t know what I was going to do with that. But I sure knew I liked to build things. I used my brain, my imagination, my body, my coordination, my balance, my eyes—all that stuff. It seemed so rich an endeavor—I just loved it.”
Parker also did serious repair work as a guitar tech in those early years. One of the first and most troubling things he learned on that job was the appalling state of fretwork on even guitars right off the shelf. “It’s better now than it was 30 years ago. I was doing refrets on brand-new, made-in-America guitars that were unplayable. I was offended. I felt that those companies weren’t taking musicians and their needs seriously, and it really bothered me.”
That eventually led to the now-legendary stainless-steel fretwork on the Parker Fly. “I had done thousands of fret jobs by the time I started that company. And one of the original design goals I told my partner, Larry Fishman, was “If I can’t build a guitar that doesn’t need fretwork, I don’t want to do it.”
Evolution of a Revolutionary
This Brownie model features a red
spruce top, curly mahogany (on

European spruce neck core.
Parker got serious about playing jazz guitar
when he was 22, and he took group lessons
with a teacher named Dick Longale. One of
the most important things that happened in
those lessons was that they gave him his first
exposure to a good archtop—Longale’s Gibson
L12. “It was beautifully balanced, rich sounding,
complex . . . We were all trying to turn
the knobs on our guitars to try and sound like
Dick, but we couldn’t. So I was intrigued.”
The other significant development was
Parker’s realization that he wasn’t going
to be a player. “No matter how much I
practiced, I was still struggling after two or
three hours a night. So I said, ‘Well, maybe
I’ll just try and make one of these things.’
That was in 1974.”
Parker’s Brief Archtop Primer
Being in the New York area was a boon for
Parker and his aspiration, because it offered
him many opportunities to get his hands on
archtops. He quickly became an avid student.
“The archtop guitar is one of the very few
instruments on our planet that was not the
product of an intensive period of competition
by competent builders. You can count
on one hand the number of people who
built archtop guitars by hand before 1975.
And that’s just weird. The pianoforte came
from these little carry-around-in-a-suitcase
instruments, and it took 300 years to develop.
The violin went through a huge period
of development—we’re talking
centuries. And even the classical
guitar is still evolving. But the archtop
was basically stillborn.”
By that, Parker means that many of the earliest archtops left a lot to be desired. “They weighed a ton—they were made like packing crates. Then all these marketing geniuses got together with all these German craftsmen in Kalamazoo, and they made some pretty cool stuff—mandolins, flattop guitars, archtop guitars in the model of [Orville] Gibson . . . but they made them better. And then, in 1922 they hired this genius [named] Lloyd Loar. He was only at the company for about 26 months, and in that time he invented and perfected the F5 mandolin, the Mastertone banjo, and the L5 guitar. He is my hero.”
The L5 did get some improvements after Loar left Gibson in 1924. “The examples that are most highly prized by people who listen were made in ‘27, ‘28, and ‘29,” Parker continues. “You could make an argument that no one seriously built an acoustic archtop since 1929 except for two people, D’Angelico and Stromberg, because in 1938 Charlie Christian came along. He was like an evangelist— ‘Get a pickup guys!’ And everybody did!”
After that, archtops were built heavier to avoid feedback—but that made them less responsive and rich sounding. “They were really electric guitars with air inside,” Parker says. “I don’t mean to say there weren’t some brilliant guitars made by these guys—and hats off, because when they came out great, they were great. But a lot of them were pretty clunky, quiet instruments.”
Achieving “Knighthood”
Mrs. Natural has a red spruce top,
rift-cut Big Leaf maple (on
the back, sides, and neck), a bronze
tailpiece, and snakewood veneers on
the fretboard, headstock, strap
buttons, and bridge
In 1976, a young Parker tried to get an
apprenticeship in Jimmy D’Aquisto’s shop.
He took the first archtop he’d made to
show D’Aquisto that he was serious. He was
turned down, but D’Aquisto clearly saw
something magical in the
instrument Parker had made.
“He said, ‘This is the best first
guitar I ever saw,’ and on my way out
the door he said, ‘You’re crazy if you stop
building guitars.’ I walked out of there
going, ‘I guess I’m a guitar maker.’ He
shop in 1976.”
Thus began the obsession. “This is what I think about before I go to bed, what I think about in the shower. I’ve worked on thousands and thousands of guitars. I’ve seen all the good stuff and all the funny stuff, and I’m trying to make my contribution to the field and make a better guitar.”
One of Parker’s innovations is his bridge. “The majority of the response from any acoustic guitar comes from the top—not only the two pieces of wood that normally make the top, but also the braces and the bridge. For reasons I don’t understand, most people don’t think of the bridge as a transverse brace. But that is exactly what it is. On the classical and flattop, it’s bonded to the top, and on an archtop it’s forced down against the top. It’s well known that the material in the bridge, the size and weight of the bridge, and the configuration of the bridge impact the sound of the instrument. And not only is the bridge a transverse brace, it’s also a transducer that changes vibrational energy into sound energy by delivering the vibrations to the top. It’s a key part of the signal path from the strings to the top. So why are we taking this holy piece of material, cutting it in half, and putting a couple of hokey pieces of 6-32 brass rods and adjusters in there? It never made any sense to me.”
Parker makes most of his bridges out of ebony. They start out at 120 grams, but he hollows them until to 21–24 grams. “It would blow off a bench in a little breeze. It is no thicker than an eighth of an inch, and many places are much thinner than that. That’s partly what contributes to the low end of the dynamic range. You haven’t got string and it’s very happy to light up and make a sound.”
Since these miniscule bridges cannot be adjusted to change the action, Parker decided to make action height adjustable by the player, on the fly. The neck literally floats over the guitar’s top—the only thing touching the body, aside from the bridge and tailpiece, is a carbon-fiber neck pin that extends into a thin-walled receptacle of aluminum tubing bonded inside the neck block. On the back of the guitar is a small, round grommet through which a hex wrench can be used to move the neck up for ridiculously low action or down to, say, play slide.
“With [that design], I got all these other great features: incredible access to the second octave because there is no heel, de-mountability for repair or travel, lots of room for a neck-end-mounted electromagnetic pickup, and the ability to fit another neck to the guitar for a different scale, a different number of strings, or whatever.”
It took Parker nearly a year to perfect his neck system. “I start with a neck core out of my favorite stuff—beautiful-sounding, perfectly quartersawn Douglas fir or spruce. This one-piece core is only visible on the side of the headstock, but it goes all the way to the end of the neck. The back of the neck has a hardwood veneer that matches the sides. Between the veneer and the neck core there’s quite a bit of carbon fiber set in an aerospace resin that needs two hours at 275 degrees Fahrenheit to cure. Room-temperature resins just aren’t rigid enough to do that job. It’s kind of challenging—you have to make a metal mold, you have to get the resin pretty hot, and it’s kind of tough to control all those things and have them all come out looking gorgeous at the end. I can’t tell you how happy I am with the result. It works just beautifully.”
Hold Your Head(stock) High
Parker makes every single component of his archtops except the tuners and the strings. For the tuners’ home—the headstock—Parker machines a strop of aluminum that resembles the Parker Fly’s headstock, has it anodized, and then, unlike most archtops, positions the tuning pegs in a row. But he doesn’t use this arrangement for aesthetic or branding reasons. He says there are two things that can change the dynamic tension of a string: the angle over the bridge and the nut, and the after length—the distance between the bridge and the termination at the tailpiece, and between the nut and the tuning peg.

height and action.
“That’s why, in one man’s opinion, a three-and-three headstock is just plain-old physically wrong.” Parker reasons that it doesn’t make sense for the tension of the high-E and the B strings to be the same as the low-E and A strings. “I think it makes the strings feel wrong. You have to get everything right in order to create an extraordinary experience for the player, and I really try to get this balancing-the-string-tension thing right. It’s not my idea—this is a European idea from hundreds of years ago—but the only way to do it is to put all the strings in one line, so the top string is more supple than it would be otherwise, and there’s a nice, even progression in tension.”
He says that arrangement facilitates greater customization, too. “For example, if you primarily play rhythm guitar, and you don’t care so much about bending strings, I’m going to make you a left-handed headstock for your guitar so you can put huge strings on the bottom and they won’t feel too tight—and they’ll drive the pickup crazy.”
Parker says his headstock angle makes the instrument feel more playable, too. “Gibson’s is 14 degrees. Mine’s four and a quarter. It’s as low as you can get it and not [have the strings] come out of the nut slots and start behaving badly. And I know, because I’ve explored it!”
This view of the Fig reveals its

made anodized aluminum strip.
Wooden Boxes
Arguably, one of the sexiest things about the Parker archtop is the way he’s cut the soundhole into the shoulder instead of putting f-holes on either side of the bridge—although he’s certainly not the first luthier to shift the soundhole or change its shape. “Now, I realize I said Lloyd Loar is my hero, and it was his idea to [put f-holes on the top] in the first place. Having said that, it still doesn’t look like the right place to me, because that’s valuable real estate—that’s part of my ‘speaker cone.’ I put the soundhole in what I call the least-worst place. It’s as far away from the bridge as I can get it, and it’s as close to the player as I can get it. It delivers this immediate sound that makes people feel so confident. A lot of low end is available to the player.
“I have been able to create a guitar that has very, very even output, note to note and string to string, and very, very good separation within chords. You can play a chord with consonant or dissonant notes, and you can hear all the notes. It doesn’t turn into a bunch of stirred-up warm ice cream. Note separation, clarity, and evenness— those are big targets for me.”
Parker’s optional pickup was designed by Scottish archtop builder Mike Vanden, who collaborated with Larry Fishman to create the Fishman Rare Earth soundhole pickup. For his archtops, Parker takes the pickup apart and puts the coils in an ebony-veneered box that rests unobtrusively at the end of the fretboard. He hides the batteries, 1/8" jack, and controls under the pickguard. it serves these guitars beautifully through a variety of amps. With an L.R. Baggs Core 1, it sounded stunningly clear, brilliant, and full. Plugged into a Vox AC15, it produced a wildly satisfying growl while retaining the richness that defines the guitar.
As for the main “box” on a Parker archtop, it’s gloriously empty. Look inside the soundhole, and you see nothing but hand-bent kerfing and an X-braced top with two delicate pieces of spruce. “When I brace a guitar, I put in two braces,” Parker explains. “They’re off-center, for nefarious reasons of my own, and they don’t touch. I glue one brace on first and tune it, and then I glue on another brace that hops over the first brace. They taper out to little tiny whiskers at the glue line. If you don’t do that, you won’t get a big, supple low end—period. The braces are there not to keep the top from collapsing, they’re there to unify the behavior of the top so that it doesn’t get out of phase with itself and create dead spots and wolf notes. If there’s a trick, if there’s a secret, it’s getting those five pieces of wood—the two sides of the top, two braces, and one bridge—to work together to be an efficient structure so that you can get some real dynamic range out of the guitar.”
The soundport offers a look at
Mrs. Natural’s immaculate interior.
As for the wonderfully natural-looking and satin-soft finish on his guitars, Parker says it’s clean, easy to apply, and environmentally safe. He first applies an epoxy sealer, wipes it off, and then applies an old-fashioned oil varnish that’s designed for gun stocks. “If you put on a few coats, it looks kind of satiny and dry, and if you put on twenty coats it looks glossy and wet. And it’s repairable in a way that other finishes simply aren’t. If you get a dent in the top but you haven’t busted any fibers, you can pretty much take the dent out with an iron and a wet cloth.”
The Goose Bump Dance
When all is said and done, it’s no exaggeration to say that Parker doesn’t just walk the line between artist and scientist, he dances along it. His archtops are handmade, utterly unique masterpieces—from the strap button to the tuning-gear strop. He sums up his motivation and mission statement by saying, “I want to build instruments that give people goose bumps—and I don’t really care that it takes me a long time. Because when people play my archtops they say, ‘This makes my Martin sound like there’s a blanket over it.’ And that’s what I want to hear!”
Silvertone Guitars introduces the new Silvertone Lipstick pickup and 1373 Baritone guitar.
Silvertone Guitars is thrilled to announce a groundbreaking collaboration with Rio Grande Pickups to introduce a new Silvertone Lipstick pickup. This partnership combines Silvertone’s iconic legacy with Rio Grande’s expert craftsmanship to create a pickup that delivers a bold, traditional single-coil tone while retaining the classic Lipstick look.
The original Lipstick pickup, invented by Nathan Daniels, is celebrated for its distinctive sound with a bright, trebly top end and scooped midrange, offering a unique sonic character that stands out both in recordings and live performances. While the classic Silvertone Lipstick pickups are known for capturing this vintage tone, the new Silvertone/Rio Grande Lipstick pickups provide an exciting twist for players seeking a higher-output, traditional single-coil sound.
Designed and handmade in Houston, Texas, the new Silvertone Lipstick pickup features an Alnico 5bar magnet, plain enamel 44AWG pure copper wire, and a shielded 2-wire connection for versatile wiring options. This pickup strikes a perfect balance between a '60s Strat®-style sound and the powerful punch of a P90, offering a beefy midrange and enhanced output for dynamic lead playing and driving effects pedals.
“We’re thrilled to be working with Rio Grande Pickups on this new Lipstick design,” says Rick Taylor, Guitar Product Manager at Silvertone Guitars. “This collaboration has allowed us to expand the tonal palette of our Lipstick pickups while preserving the visual appeal that players love. The new pickups deliver rich, powerful sound that will inspire musicians to explore new creative possibilities.”
These new pickups are the perfect way to supercharge your guitar, combining the distinctive look of the Lipstick design with the versatile, high-output tone that modern players demand.
Pricing is $279 for the calibrated set, and $159 for the neck or bridge alone.
Silvertone Guitars proudly introduces the 1373 Baritone, a contemporary reimagining of the iconic 1958 6-string bass.
In 1958, Silvertone made waves with the revolutionary 1373 model, a 6-string bass tuned low E to E, paving the way for the distinctive tic-tac technique in Nashville. This technique involved doubling acoustic bass lines with the six-string bass played with a pick. This unique tuning was also famously featured in Glen Campbell's iconic six-string bass solo on the hit single "Wichita Lineman."
With the 1373 Baritone, Silvertone pays homage to this rich history by transforming the instrument into a baritone tuning marvel. The 28” scale neck is meticulously designed for B to B tuning, echoing the popular baritone tuning that left an indelible mark on 1960s surf rock and spaghetti western soundtracks.
Crafted with a solid mahogany body, the 1373 Baritone delivers unparalleled punch and sustain. The string-through body bridge enhances resonance, and the 28” scale strikes the perfect balance, allowing the lower strings to resonate authentically without sacrificing the comfort of standard tuning guitars.
Equipped with the new Alnico 5 Silvertone Lipstick pickups, the 1373 Baritone retains the clean tones and bell-like top end of the original pickups, with a bit more output. This additional output provides the flexibility to comfortably drive pedals, tube amps, or digital modelers, making the 1373 Baritone a versatile instrument across various musical genres.
The 1373 Baritone carries a $449 street price and is available in three striking colors: Black SilverFlake, Pelham Blue, and Silver Metal Flake.

Orange Amplification announces the arrival of its new Babies: the newly analogue designed Dual Baby, Tour Baby and Gain Baby guitar amps, plus the O Tone combo.
The Babies
Each lightweight, studio grade 100W, twin channel, Class A/B, solid state amp weighs only 3kg and is compact, reliable and tour ready. Watch the launch video here.
The 2-channel, Tour Baby guitar amp is incredibly versatile in a variety of playing situations. The onboard studio grade VCA compressor of Tour Baby’s refined clean channel, offers pristine clean tones with active or passive pickups. It provides a consistent dynamic range and low noise in extreme settings without the need for separate pedals. It includes precise bass and treble EQ controls.
The naturally voiced dirty channel of this tone machine allows players to easily get that sought after ‘point of breakup’ sound . A custom voiced presence control and powerful 3-band EQ control means the Tour Baby’s tone can be shaped to cut-through the mix. Add to that a footswitchable volume control, that provides a stage-friendly volume boost option for live applications. Watch the Tour Baby video here.
The Gain Baby clean channel is the same as that of the Tour Baby with its integrated VCA Compressor to alleviate the need for an additional stomp box and incorporates bass and treble EQ controls to dial in a desired frequency. The compressor provides smooth, transparent compression for dynamic control without compromising tone.
Four distinct stages are available on the high gain channel allowing players to dial in their preferred level of crunch and saturation. Like the Dual Baby, Gain Baby’s Tight Switch operates as a bright switch, boosting the upper mid at lower gain levels, to give shredding solos a little something extra. Volume control is footswitchable, the buffered FX allows effects from pedals to be patched in and the onboard 3-band EQ allows tone to be tweaked even further.
With multiple output options such as a balanced XLR output with no Cab Sim, as well as dual speaker outputs, the Gain Baby is equally comfortable on stage or in the studio. Watch the Gain Baby video here.
The Dual Baby is a powerhouse in a pint-sized package. It’s simple A and B channel design offers duelling tones and alternating rhythm opportunities. Channel A mimics the rich responsive tones of the Orange flagship Rockerverb amps in a reliable solid-state design. From clean to classic crunch to full-on saturation, there is no shortage of Orange mojo. The brand-new Tubby Switch, which boosts the bottom end early in the signal path, offers a much ‘rounder’ tone when playing clean or when searching for just the right ‘dirty-clean’ sound.
Channel B allows players to dial in the desired level of grit, with ample saturation and a valve-like high-gain tone, unheard of in any other solid-state unit. The ‘bright boost’ of the Tight Switch gives the amp spring and bounce and raises the top end at lower gain levels for players who want to tighten up, shred and play blistering solos with plenty of cut. The 3-band sweepable EQ presence control allows frequencies to be tweaked, shimmer added and mids that sit perfectly in the mix to be dialled in. Watch the Dual Baby video here.
Pack or rack any of the three Baby amps with included gig bag or an available rack ear kit. Each Baby is a mighty unit that delivers100-Watts into 8 ohms or 70-Watts into 16 ohms, to power any full-sized guitar amp with ease!

The O Tone 40 Combo Amp
Watch the launch video here.
The single channel, 40-Watt Class A/B solid state combo has onboard tremolo and reverb controls, a buffered effects loop and plenty of punchy volume. With a distinctive clean tone, it is an ideal amp for any pedal set-up or a small venue workhorse for guitarists who are fond of warm, vintage tones.
The amp’s bias-wobbled, single-ended JFET tremolo circuit offers huge depth and breadth, delivering everything from grand sweeps to a staccato sonic character via insistent, whirling helicopter patterns. The effect is footswitchable, allowing for even more adaptability during performances.
Modelling a classic spring reverb, the O Tone 40 incorporates a digital reverb module to add a warm spaciousness to sounds, ranging from subtle shimmer to ethereal trails.
The combo’s fully buffered, low-impedance FX Loop allows for any number of effects and cables to be patched between the amp’s input and output sections without sacrificing tone, making it an excellent pedal platform.
The powerful volume of the 12” Voice of the World speaker, combined with the amazingly sweet tones and harmonic chimes of the new O Tone 40, makes it ideal for rock, country, blues and so many more music genres. A direct output is included to facilitate studio and live non-miked situations.
The amp is finished in trademark Orange Tolex with Orange’s signature basket- weave grill and Crest badge. Check out the O Tone 40 and all the other Orange products at https://orangeamps.com/
The Los Angeles League of Musicians—LA LOM for short—brought the vintage vibe with them on the road last year.
It wasn’t long ago that LA LOM—guitarist Zac Sokolow, bassist Jake Faulkner, and percussionist Nicholas Baker—were cutting their teeth together as the house band at the Roosevelt Hotel in Hollywood, playing poolside for guests. Now, with eight EPs and a full-length record (2024’s The Los Angeles League of Musicians) since 2021, they’re a full-blown sensation, celebrating and interpreting instrumental tropical guitar traditions.
The trio played Nashville’s The Basement back in December, where PG’s John Bohlinger caught up with Sokolow and Faulkner to see what road rigs they use to bring their psychedelic cumbia and Peruvian chicha dreams to life.
Brought to you by D’Addario.Red Rider
This vintage National Val-Pro, circa 1960 to 1962, belongs to Faulkner, who received it as his very first electric. When he switched to bass, the Val-Pro took a backseat, so Sokolow had been more than happy to borrow it long-term. All the controls are disconnected except for the volume knob. Sokolow strings it with a .012–.052 gauge set of roundwounds, and he’s partial to D’Andrea Pro Plec 1.5 mm picks.
Leader of the Pack
Sokolow’s other sidekick is this Kay Style Leader from 1960. Each of the three pickups has a volume and tone control. The body’s been mostly routed out, so it lends the resonance and darkness of a semi-hollowbody.
Live and Loud
While he’ll often play through Fender Deluxe Reverbs at home, Sokolow trusts the Twin Reverb to get the job done in performance settings. The stage volume is loud enough that he and his bandmates often don’t need monitors: They can just listen to each other’s instruments onstage.
Zac Sokolow's Pedalboard
From his guitar, Sokolow’s signal runs through a spicy-red Voltage Cable Co. coil cable into his board. A TC Electronic Polytune 2 starts things off, followed by a Fulltone Full-Drive 3 for just a hint of dirt, then a Boss DM-3 delay, followed by a Catalinbread Topanga spring reverb. A TC Helicon VoiceTone handles some more echo work along with the DM-3.
Flight-Friendly Upright
Jake Faulkner’s traveling upright is thisJohnson bass, which has been modded by Tom at Fantastic Musical Instruments in Pasadena, California. Tom gave the upright a bolt-on neck that comes off easily, making it a perfect travel mate. For amplification, Faulkner uses pickups from Underwood, based in Palm Springs. On a tip from Tom, he glued a small piece of wood to the side of the pickups to reduce noise issues, and two sound posts have been installed inside the body to reduce feedback concerns.
Thumbin' Through
For electric needs, Faulkner uses this Fender Vintera II ’60s Precision Bass; he’ll switch between the two basses depending on what he feels best suits the song. He uses a thumb pick from time to time to accentuate certain rhythms.
Lightweight Low End
Faulkner’s been converted to this Ampeg Venture V12, a compact bass head weighing less than nine pounds—a godsend for sore-backed bassists. It’s set for a pretty neutral, SVT-style sound and runs into a Fender Bassman 410 Neo cabinet, which has four neodymium-loaded speakers.
Jake Faulkner's Pedalboard
Rather than at the start of his chain, his Korg Pitchblack Advance tuner goes at the end, with everything running out of it to the Venture V12. An Origin Effects Bassrig Super Vintage lends color and tone to the V12, then the Fire-Eye Development Red-Eye Twin acts as an A/B switch to maintain output and gain between the Johnson and the P-bass. An MXR Ten Band EQ helps balance out the upright’s tone.
