Matchless'' Avalon incorporates partial PC-board construction for more affordable boutique sound
At the beginning of the boutique amp boom
in the late 1980s and early ’90s, one of the
biggest names being bandied about was
Matchless. Original designers Rick Perotta,
Chris Perotta, and company co-founder Mark
Sampson were huge Beatles fans, and that
jangly AC30 sound drove them to start analyzing
and repairing vintage Voxes imported
from the UK. Eventually, they took the next
logical step and began building handwired,
roadworthy interpretations of the iconic AC30.
Sampson, Rick Perotta, and John Jorgenson
(who would later go on to gain acclaim for
his work with Will Ray and Jerry Donahue in
the Hellecasters) came up with the company’s
most famous designs—the now-legendary
DC30, Chieftain, and Lightning—which became
staples for artists as diverse as Jimmie
Vaughan, Hank Marvin, Alex Lifeson, and Toad
the Wet Sprocket’s Glen Phillips.
But by 1998, the company had serious
financial troubles and had to close shop.
Amp nuts everywhere lamented Matchless’
demise and the original amps skyrocketed in
value overnight. Just prior to Matchless MK I’s
implosion, they hit on an idea that might have
saved the company, given time. The idea: offer
more affordable amps that incorporate the
same quality components as other Matchless
models, but in a circuit with limited PC-board
construction, channel switching, and footswitchable
reverb.
So, they gave it a whirl. The Superliner series
was supposed to include three models, but
only the 40-watt, EL34-powered Starliner
Reverb 2x12 and the 15-watt, EL84-powered
Skyliner Reverb 2x10 ever got off the
ground—and in extremely limited numbers.
According to Phil Jamison—who became
Matchless’ production manager in 1994 and
helped get the company back on its feet in
2000—fewer than 10 Starliner and Skyliner
amps were produced, and several of them
were returned due to faulty operation.
For more than a decade now, Jamison
and current owner Geoff Emery have kept
Matchless going steady and strong by offering
most of the original amp designs and
coming up with innovative new models for
a wider array of players—including those
with high-gain needs. They also recently
began offering more affordable amps, first
the EL84-powered Avalon 30 and now the
EL34-powered Avalon 35, that incorporate
top-shelf components in a design with partial
PC-board construction. It’s a move many
boutique builders have made since the beginning
of the recession.
Forging Excalibur
Consumer products in general often have
names that convey a gross inflation of their
true worth, and guitar gear is no different.
But sometimes those lofty-sounding names
aren’t far from the mark. Look up “Avalon”
and you’ll discover that, in Arthurian legend,
it was the island where King Arthur’s magical
sword, Excalibur, was forged. I don’t know if
that’s what Matchless was going for, but I like
the possible comparisons the name suggests.
For a lot of players, acquiring the Avalon
35—which retails at $2629 (with reverb, $2599
without)—isn’t going to be as easy as lifting the
amp from an enchanted stone, but compared to
the similarly featured SC-30 combo, it’s a relative
steal. Likewise, despite having a feature set that’s
rather primitive by modern standards, the amp
isn’t without its magic. Inside, the Avalon combines
two EL34s, five 12AX7s (three for the preamp,
two for the reverb), a 5AR4 tube rectifier,
and the same quality components used in other
Matchless amps—including robust transformers—
in a class-A, cathode-biased hybrid circuit
that uses both point-to-point, turret-style construction,
and cost-cutting PC-board elements. The front panel features Hi and Lo instrument
inputs, Standby and On/Off rocker switches,
and six “chicken-head” knobs—Volume, Bass,
Treble, Cut, Master Push/Pull, and Reverb. Like
the front panel, the rear panel is simple and
intuitive. It features jacks for an extension cabinet
and the built-in 30-watt Celestion G12H
speaker, a three-position Impedance selector,
jacks for the series effects loop and optional
reverb footswitch, a fuse receptacle, and a
standard IEC power-cord receptacle.
The amp weighs a hefty 62 lbs. and measures
21 ¼" W x 23 ¼" H x 11 ¼" D. My construction
niggles are very minor. First, though the
Avalon’s dimensions are comparable to the
original SC-30 1x12 combo, the unusual height
may be an awkward schlep for shorter players,
who may have difficulty carrying it straigh-tarmed
without bumping or dragging it on the
ground. Second, though there are labels above
the front-panel controls, they’re hard to read
without squatting. Otherwise, there’s almost
nothing to fault in the Avalon’s construction.
The black covering is virtually flawless, the
silver piping is cleanly cut and applied, and the
salt-and-pepper grillcloth looks fantastic. And
let’s not forget the badass rear-lit logo—one of
the most iconic looks in all of ampdom.
The Matchless Avalon 35 features a hybrid circuit with both PC-board-mounted components and point-to-point-wired, chassis-mounted
tube sockets and controls.
Wielding the Blade
I tested the Avalon with a nice variety of guitars,
including a ’60s Strat reissue with Custom Shop
Fat ’50s pickups, a PRS Ted McCarty DC 245
with 57/08 humbuckers, a Schecter Ultra III
with splittable mini-humbuckers, and a Gretsch
G6118T-LTV with TV Jones Classics. With each
axe, the tones were dynamic, detailed, and
varied. The key to the variety is the Master
Push/Pull knob, which enables you to go from
needling AC30 glory to higher-gain, Marshall
plexi-type sounds at less problematic volumes.
For the former, you’ll want Master Push/Pull
disengaged (pushed in) so you can experience
the open, airy feel that comes when you let the
Volume knob control both gain and output. For
rock and hard-rock sounds, turn Master Push/
Pull to a lower setting (so you don’t get blasted
in the face) and crank Volume toward its upper
regions for rich distortion. As with most master-volume
amps, this convenient feature is very
practical, though it slightly darkens the timbres
and decreases some of the to-die-for dynamics.
With Volume and Master Push/Pull nearing their
limits, things can get splatty and fizzy, but the
same can be said of a lot of classic amps.
The Avalon’s EQ is remarkably interactive,
too. As with classic Vox and Matchless
circuits, Cut shaves off high-end frequencies
as you turn it clockwise. When it’s completely
counterclockwise, you get those glassy
sounds made famous by the Who and the Fab
Four. With it maxed, you get a thick, scooped-out
tone that could accommodate jazz cats
or rock guys looking for notched mids. While
jazz cats won’t be the first to gravitate to an
amp like the Avalon—and the same probably
goes for hardcore rockabilly guys—I got fat,
neck-pickup jazz tones and bristling rockabilly
bombast with the Gretsch.
The Treble and Bass knobs work like they do
on other amps, and the latter in particular
has much more impact than many other tube
amps. Dime it, and you get more mids for a
honkier sound—but in a musical, absolutely
usable way. Bring it back a bit, say, to three or
four o’clock, and you get muscular, in-your-face
tones. My playing runs the gamut from
heavy-handed rock/rockabilly riffing and
chording to a lot of hybrid picking, so I eventually
settled on Volume at two or two-thirty,
Master Push/Pull off, Bass at two o’clock,
Treble dimed, Cut off, and Reverb—a three-spring
unit that adds nice dimension but less
depth than I’d hoped—at two o’clock. This
let me get the broadest array of tones, from
all-out brashness and crystalline detail to full,
rounded notes by going from a heavy pick
attack to curling the plectrum under my index
finger and strumming with my thumb. With
the Strat, I got deliciously detailed quackiness
in the in-between positions—perfect for
Southern rock flavors or funky chording like in
Queen’s “Another One Bites the Dust.” With
the Schecter, I got raw, in-your-face indie-rock
sounds using the bridge pickup. The PRS
yielded everything from Zeppelin-esque PAF
sounds to fat neck-pickup tones that would
make SRV proud.
The Final Mojo
Like a lot of aficionados of high-end anything,
guitarists can get pretty hung up on certain
details before they’ve even tried a product.
They might dismiss an amp for even minimal
PC-board construction or because it wasn’t
designed during a certain period of the company’s
history. There’s a kernel of wisdom in
some arguments over such minutia, because
the longer you play, the more you realize your
sound is the sum of all the little things—from
your pick gauge to how hard you fret and
what kind of tubes are in your amp. But we
all know such obsession can be crippling, too.
The trick is to do your homework and find
great equipment, and then focus more on
your playing and your ear than on your gear.
That’s what most of our heroes did (or do).
And that’s why I really dig the new Matchless
Avalon 35. It offers an excellent balance of
flexibility, durability, and quality tone.
Buy if...
you revel in bristling, dynamic EL34 tones and simplified flexibililty.
Skip if...
you want more sophisticated control of surf-able reverb.

Single-coils and humbuckers aren’t the only game in town anymore. From hybrid to hexaphonic, Joe Naylor, Pete Roe, and Chris Mills are thinking outside the bobbin to bring guitarists new sonic possibilities.
Electric guitar pickups weren’t necessarily supposed to turn out the way they did. We know the dominant models of single-coils and humbuckers—from P-90s to PAFs—as the natural and correct forms of the technology. But the history of the 6-string pickup tells a different story. They were mostly experiments gone right, executed with whatever materials were cheapest and closest at hand. Wartime embargos had as much influence on the development of the electric guitar pickup as did any ideas of function, tone, or sonic quality—maybe more so.
Still, we think we know what pickups should sound and look like. Lucky for us, there have always been plenty of pickup builders who aren’t so convinced. These are the makers who devised the ceramic-magnet pickup, gold-foils, and active, high-gain pickups. In 2025, nearly 100 years after the first pickup bestowed upon a humble lap-steel guitar the power to blast our ears with soundwaves, there’s no shortage of free-thinking, independent wire-winders coming up with new ways to translate vibrating steel strings into thrilling music.
Joe Naylor, Chris Mills, and Pete Roe are three of them. As the creative mind behind Reverend Guitars, Naylor developed the Railhammer pickup, which combines both rail and pole-piece design. Mills, in Pennsylvania, builds his own ZUZU guitars with wildly shaped, custom-designed pickups. And in the U.K., Roe developed his own line of hexaphonic pickups to achieve the ultimate in string separation and note definition. All three of them told us how they created their novel noisemakers.
Joe Naylor - Railhammer Pickups
Joe Naylor, pictured here, started designing Railhammers out of personal necessity: He needed a pickup that could handle both pristine cleans and crushing distortion back to back.
Like virtually all guitar players, Joe Naylor was on a personal tone quest. Based in Troy, Michigan, Naylor helped launch Reverend Guitars in 1996, and in the late ’90s, he was writing and playing music that involved both clean and distorted movements in one song. He liked his neck pickup for the clean parts, but it was too muddy for high-gain playing. He didn’t want to switch pickups, which would change the sound altogether.
He set out to design a neck pickup that could represent both ends of the spectrum with even fidelity. That led him to a unique design concept: a thin, steel rail under the three thicker, low-end strings, and three traditional pole pieces for the higher strings, both working with a bar magnet underneath. At just about a millimeter thick, rails, Naylor explains, only interact with a narrow section of the thicker strings, eliminating excess low-end information. Pole pieces, at about six millimeters in diameter, pick up a much wider and less focused window of the higher strings, which works to keep them fat and full. “If you go back and look at some of the early rail pickups—Bill Lawrence’s and things like that—the low end is very tight,” says Naylor. “It’s almost like your tone is being EQ’d perfectly, but it’s being done by the pickup itself.”
That idea formed the basis for Railhammer Pickups, which began official operations in 2012. Naylor built the first prototype in his basement, and it sounded great from the start, so he expanded the format to a bridge pickup. That worked out, too. “I decided, ‘Maybe I’m onto something here,’” says Naylor. Despite the additional engineering, Railhammers have remained passive pickups, with fairly conventional magnets—including alnico 5s and ceramics—wires, and structures. Naylor says this combines the clarity of active pickups with the “thick, organic tone” of passive pickups.
“It’s almost like your tone is being EQ’d perfectly, but it’s being done by the pickup itself.” —Joe Naylor
The biggest difficulty Naylor faced was in the physical construction of the pickups. He designed and ordered custom molds for the pickup’s bobbins, which cost a good chunk of money. But once those were in hand, the Railhammers didn’t need much fiddling. Despite their size differences, the rail and pole pieces produce level volume outputs for balanced response across all six strings.
Naylor’s formula has built a significant following among heavy-music players. Smashing Pumpkins’ Billy Corgan is a Railhammer player with several signature models; ditto Reeves Gabrels, the Cure guitarist and David Bowie collaborator. Bob Balch from Fu Manchu and Kyle Shutt from the Sword have signatures, too, and other players include Code Orange’s Reba Meyers, Gogol Bordello’s Boris Pelekh, and Voivod’s Dan “Chewy” Mongrain.
Chris Mills - ZUZU Pickups
When Chris Mills started building his own electric guitars, he decided to build his own components for them, too. He suspected that in the course of the market’s natural thinning of the product herd, plenty of exciting options had been left unrealized. He started working with non-traditional components and winding in non-traditional ways, which turned him on to the idea that things could be done differently. “I learned early on that there are all kinds of sonic worlds out there to be discovered,” says Mills.
Eventually, he zeroed in on the particular sound of a 5-way-switch Stratocaster in positions two and four: Something glassy and clear, but fatter and more dimensional. In Mills’ practice, “dimensional” refers to the varying and sometimes simultaneous sound qualities attained from, say, a finger pad versus a fingernail. “I didn’t want just one thing,” says Mills. “I wanted multiple things happening at once.”
Mills wanted something that split the difference between a humbucker’s fullness and the Strat’s plucky verve, all in clean contexts. But he didn’t want an active pickup; he wanted a passive, drop-in solution to maximize appeal. To achieve the end tone, Mills wired his bobbins in parallel to create “interposed signal processing,” a key piece of his patented design. “I found that when I [signal processed] both of them, I got too much of one particular quality, and I wanted that dimensionality that comes with two qualities simultaneously, so that was essential,” explains Mills.
Mills loved the sound of alnico 5 blade magnets, so he worked with a 3D modeling engineer to design plastic bobbins that could accommodate both the blades and the number of turns of wire he desired. This got granular—a millimeter taller, a millimeter wider—until they came out exactly right. Then came the struggle of fitting them into a humbucker cover. Some key advice from experts helped Mills save on space to make the squeeze happen.
Mills’ ZUZUbuckers don’t have the traditional pole pieces and screws of most humbuckers, so he uses the screw holes on the cover as “portholes” looking in on a luxe abalone design. And his patented “curved-coil” pickups feature a unique winding method to mix up the tonal profile while maintaining presence across all frequencies.
“I learned early on that there are all kinds of sonic worlds out there to be discovered.” —Chris Mills
Mills has also patented a single-coil pickup with a curved coil, which he developed to get a different tonal quality by changing the relative location of the poles to one another and to the bridge. Within that design is another patented design feature: reducing the number of turns at the bass end of the coil. “Pretty much every pickup maker suggests that you lower the bass end [of the pickup] to compensate for the fact that it's louder than the treble end,” says Mills. “That'll work, but doing so alters the quality and clarity of the bass end. My innovation enables you to keep the bass end up high toward the strings.”
Even Mills’ drop-in pickups tend to look fairly distinct, but his more custom designs, like his curved-coil pickup, are downright baroque. Because his designs don’t rely on typical pickup construction, there aren’t the usual visual cues, like screws popping out of a humbucker cover, or pole pieces on a single-coil pickup. (Mills does preserve a whiff of these ideals with “portholes” on his pickup covers that reveal that pickup below.) Currently, he’s excited by the abalone-shell finish inserts he’s loading on top of his ZUZUbuckers, which peek through the aforementioned portholes.
“It all comes down to the challenge that we face in this industry of having something that’s original and distinctive, and also knowing that with every choice you make, you risk alienating those who prefer a more traditional and familiar look,” says Mills.
Pete Roe - Submarine Pickups
Roe’s stick-on Submarine pickups give individual strings their own miniature pickup, each with discrete, siloed signals that can be manipulated on their own. Ever wanted to have a fuzz only on the treble strings, or an echo applied just to the low-register strings? Submarine can achieve that.
Pete Roe says that at the start, his limited amount of knowledge about guitar pickups was a kind of superpower. If he had known how hard it would be to get to where he is now, he likely wouldn’t have started. He also would’ve worked in a totally different way. But hindsight is 20/20.
Roe was working in singer-songwriter territory and looking to add some bass to his sound. He didn’t want to go down the looping path, so he stuck with octave pedals, but even these weren’t satisfactory for him. He started winding his own basic pickups, using drills, spools of wire, and magnets he’d bought off the internet. Like most other builders, he wanted to make passive pickups—he played lots of acoustic guitar, and his experiences trying to find last-minute replacement batteries for most acoustic pickups left him scarred.
Roe started building a multiphonic pickup: a unit with multiple discrete “pickups” within one housing. In traditional pickups, the vibration from the strings is converted into a voltage in the 6-string-wide coils of wire within the pickup. In multiphonic pickups, there are individual coils beneath each string. That means they’re quite tiny—Roe likens each coil to the size of a Tylenol pill. “Because you’re making stuff small, it actually works better because it’s not picking up signals from adjacent strings,” says Roe. “If you’ve got it set up correctly, there’s very, very little crosstalk.”
With his Submarine Pickups, Roe began by creating the flagship Submarine: a quick-stick pickup designed to isolate and enhance the signals of two strings. The SubPro and SubSix expanded the concept to true hexaphonic capability. Each string has a designated coil, which on the SubPro combine into four separate switchable outputs; the SubSix counts six outputs. The pickups use two mini output jacks, with triple-band male connectors to carry three signals each. Explains Roe: “If you had a two-channel output setup, you could have E, A, and D strings going to one side, and G, B, and E to the other. Or you could have E and A going to one, the middle two strings muted, and the B and E going to a different channel.” Each output has a 3-position switch, which toggles between one of two channels, or mute.
“I’m just saying there’s some unexplored territory at the beginning of the signal chain. If you start looking inside your guitar, then it opens up a world of opportunities.” —Pete Roe
This all might seem a little overly complicated, but Roe sees it as a simplification. He says when most people think about their sound, they see its origin in the guitar as fixed, only manipulatable later in the chain via pedals, amp settings, or speaker decisions. “I’m not saying that’s wrong,” says Roe. “I’m just saying there’s some unexplored territory at the beginning of the signal chain. If you start looking inside your guitar, then it opens up a world of opportunities which may or may not be useful to you. Our customers tend to be the ones who are curious and looking for something new that they can’t achieve in a different way.
“If each string has its own channel, you can start to get some really surprising effects by using those six channels as a group,” continues Roe. “You could pan the strings across the stereo field, which as an effect is really powerful. You suddenly have this really wide, panoramic guitar sound. But then when you start applying familiar effects to the strings in isolation, you can end up with some really surprising textural sounds that you just can’t achieve in any other way. You can get some very different sounds if you’re applying these distortions to strings in isolation. You can get that kind of lead guitar sound that sort of cuts through everything, this really pure, monophonic sound. That sounds very different because what you don’t get is this thing called intermodulation distortion, which is the muddiness, essentially, that you get from playing chords that are more complex than roots and fifths with a load of distortion.” And despite the powerful hardware, the pickups don’t require any soldering or labor. Using a “nanosuction” technology similar to what geckos possess, the pickups simply adhere to the guitar’s body. Submarine’s manuals provide clear instruction on how to rig up the pickups.
“An analogy I like to use is: Say you’re remixing a track,” explains Roe. “If you get the stems, you can actually do a much better job, because you can dig inside and see how the thing is put together. Essentially, Submarine is doing that to guitars. It’s allowing guitarists and producers to look inside the instrument and rebuild it from its constituent parts in new and exciting ways.”

The legendary German hard-rock guitarist deconstructs his expressive playing approach and recounts critical moments from his historic career.
This episode has three main ingredients: Shifty, Schenker, and shredding. What more do you need?
Chris Shiflett sits down with Michael Schenker, the German rock-guitar icon who helped launch his older brother Rudolf Schenker’s now-legendary band, Scorpions. Schenker was just 11 when he played his first gig with the band, and recorded on their debut LP, Lonesome Crow, when he was 16. He’s been playing a Gibson Flying V since those early days, so its only natural that both he and Shifty bust out the Vs for this occasion.
While gigging with Scorpions in Germany, Schenker met and was poached by British rockers UFO, with whom he recorded five studio records and one live release. (Schenker’s new record, released on September 20, celebrates this pivotal era with reworkings of the material from these albums with a cavalcade of high-profile guests like Axl Rose, Slash, Dee Snider, Adrian Vandenberg, and more.) On 1978’s Obsession, his last studio full-length with the band, Schenker cut the solo on “Only You Can Rock Me,” which Shifty thinks carries some of the greatest rock guitar tone of all time. Schenker details his approach to his other solos, but note-for-note recall isn’t always in the cards—he plays from a place of deep expression, which he says makes it difficult to replicate his leads.
Tune in to learn how the Flying V impacted Schenker’s vibrato, the German parallel to Page, Beck, and Clapton, and the twists and turns of his career from Scorpions, UFO, and MSG to brushes with the Rolling Stones.
