PRS Pedal Reviews: Horsemeat Transparent Overdrive, Mary Cries Optical Compressor, and Wind Through the Trees Dual Analog Flanger

Paul Reed Smith may hate pedals, but his first foray into the realm delivers nothing but gems.
Inside each box containing a brand new PRS pedal, there’s a little fold-out card with a picture of Paul Reed Smith and a simple caption: “I hate pedals.” It’s not hard to imagine Smith’s indifference to stompboxes. PRS guitars are immaculately executed, ultra-playable instruments that reflect a focus on elemental interactions between fingers, strings, and fretboard. Indeed, for much of Paul Reed Smith’s career, stompboxes were probably held in the same regard as a broken toaster—a needless impediment to the communication of unadulterated tone.
Certainly, there is a visceral thrill to playing a guitar without effects—particularly one as nice as the average PRS. But while that’s true, stompboxes are, to many musicians, equally artful and thrilling vehicles of expression. And more than a few pedals have done their magic with a PRS guitar at the other end of a cable.
PRS’ three debut pedals—an optical compressor, overdrive, and dual flanger—do not feel like willy-nilly concessions to market pressures. In fact, in keeping with PRS tradition and ethos, these pedals seem selected and designed to offer minimal intrusion on the guitar/amp relationship if the player chooses that route. But they also have the bandwidth to be bold and even positively extroverted. Unsurprisingly, they are also built to a very high standard of quality and reflect an intense attention to detail.
PRS Horsemeat, Mary Cries & Wind Through the Trees Demos | First Look
Horsemeat Transparent Overdrive
Horsemeat isn’t a pretty name, but I’m guessing it alludes to making short work—mincemeat, if you will—of the Klon Centaur in a head-to-head battle. It’s hard to know exactly how much inspiration PRS derived from the Klon. PRS emphatically insists that Horsemeat is a very original design. And its circuit board is flipped, making it impossible to determine similarities in topology. It shares at least one important design element with the Klon, in the form of germanium clipping diodes. In a very general sense, germanium diodes tend to contribute soft-edged compression and a high capacity for distortion. But without knowing how other components in the circuit modify the performance of the diodes, you have to rely on your ears. And alongside my favorite Klon clone, Horsemeat sounds like a very different animal indeed.
Next to the Klon clone—which serves here as a familiar baseline rather than a direct comparison—the Horsemeat’s headroom and the leeway to work with it via picking dynamics or the flexible and practical control array is striking.
Though the Horsemeat can get aggressive, moving through the gain control’s range yields many nuanced shades. At maximum gain levels (and with relatively neutral treble, bass, and voice settings), the Horsemeat exhibits a lot of Marshall-plexi-like characteristics. There’s a distinct sense of size, a viscerally satisfying growl to the voice, and lots of top-end response that gives first- and second-string output heat and room to breathe. If you keep the output level at a reasonable setting, the compression in the distortion never feels oppressive or muddy. Instead, the pedal’s natural compression tends to lend cohesion. And even at advanced output level settings (and there is a lot of room to run in that respect), the distortion remains articulate.
“Moving through the gain control’s range really yielded shades of gain rather than heaps of extra crunch and aggression.”
Reducing gain reveals an impressive capacity for touch sensitivity. I can’t remember the last gain device I used that responded so well to variations in fingerpicking intensity. Guitar volume attenuation, too, yields rich and very pretty clean tones. And if you’re frustrated by your single-coil pickup’s tendency to bleed high end with volume reduction, you’ll be tickled by how readily the Horsemeat can replace some of that sparkle.
The bass and treble controls not only have a lot of range, but offer very colorful and varied tones within those areas. You can extract exceptionally bright tones out of the Horsemeat (in fact, extra-trebly settings rather than high-gain sounds struck me as the pedal’s most “extreme” settings). The voice control, which shapes frequency response in the clipping stage, helps you color the pedal’s tones in even more specific ways. Aggressively clockwise settings sound and feel hot and explosive, while the lower-to-middle third of its range have a sweetness that works with the pedal’s intrinsic dynamism to add soulful movement to chord melodies.
The Verdict
It’s hard to imagine an overdrive user that wouldn’t dig working with the Horsemeat. Players that prefer the squish in overdriven Fender tweed circuits might find the output a touch too even across frequencies. But I suspect a lot of players that love the more articulate side of a Marshall’s voice or really obsess over relative transparency will find a soulmate in this fine and varied drive machine.
Mary Cries Optical Compressor
Like the Horsemeat, the Mary Cries comp hints at a possible PRS design team directive: That a guitar’s fundamental voice should always be able to be its best, most exciting self. That’s no surprise for a company whose instruments are typically so rich and sonorous. But like the Universal Audio Teletronix LA-2A optical studio compressor that inspired it, the Mary Cries succeeds so well that it could probably make a busted kazoo shine.
“The Mary Cries could probably make a busted kazoo shine.”
If you ever use a real LA-2A in a studio, you’ll never forget the way it fattens, flatters, and warms a signal. You’ll also be struck by how economical the layout is. Apart from a compression ratio switch, there’s a peak reduction knob (typically just called the compression control) and a make-up gain or output gain control. Even a novice can competently use an LA-2A using ears and intuition.
Building a pedal-sized optical compressor circuit does not automatically make it the equivalent of an LA-2A. That verges on the impossible. But the Mary Cries excels at the same tasks: adding body and excitement to a signal and enabling quick adjustments without overthinking the process. The Mary Cries reduces the control scheme of an LA-2A to just the compression and output gain controls (which are the controls studio engineers use most). But just as a studio LA-2A can dramatically recast a sound with these simple interactions, the Mary Cries has the capacity to completely alter the feel and force of an instrument—beyond adding sustain and mitigating the effects of nasty peaks.
Even modest compression settings on the Mary Cries also have the effect of thickening and tightening low- and low-mid frequencies, giving the perception of extra mass and resonance without overpowering the top end. Mary Cries also colors trebles with bell-like sustain that tends to decay in almost perfect balance with the fatter low end. Players often use comps to achieve balance between frequency band extremes, but the Mary Cries’ cohesiveness, if you’ll permit a food analogy, has the feel of a sauce where every ingredient shines brilliantly.
This ability to gather and highlight fundamentals and overtones in a balanced whole does wonders for simple and extended chords. And these tone composites can purr and growl gorgeously depending on where you situate your output gain. Incidentally, Mary Cries is a magnificent clean boost when you kick up the output gain and reduce the compression to a minimum.
The Verdict
Mary Cries does a superb job of sounding and feeling transformative with very little fuss. It’s beautifully built, which manifests itself in the unit’s exceptionally quiet performance. At 219 bucks, it may seem expensive to players accustomed to other superficially simple comps. But I suspect even a cursory side-by-side play with many of these units would reveal much about Mary Cries’ nuance, elegance, and value.
Wind Through the Trees Dual Analog Flanger
Compared to its relatively streamlined siblings the Mary Cries and the Horsemeat, the analog, LFO-driven Wind Through the Trees flanger looks like a handful to manage. But for all the knobs that populate the Wind’s enclosure, it’s surprisingly intuitive.
Many contemporary, digitally attuned players will insist that a pedal this full of possibilities should come with presets. But the Wind Through the Trees’ analog interface is fluid and clear enough that you can move between varied settings with relative ease. That makes exploring the pedal’s myriad textures a flat-out joy—particularly because you can home in on very specific modulation profiles to suit a musical moment.
“One of the Wind Through the Trees greatest strengths is its ability to generate very mellow and hauntingly subliminal modulations.”
Flange is not an effect players typically associate with subtlety. But one of the Wind Through the Trees’ greatest strengths is its ability to generate very mellow and hauntingly subliminal modulations. These subtleties are made possible by the Wind Through the Trees very interactive, sensitive, and rangy controls. And, in my experience at least, the LFO mix, wet/dry output, and the very clearly labeled “added highs” controls are key to these textures.
Using these controls, you can, for instance, fashion a very understated modulation on LFO 1, blend in just a touch of twitchy, deep, high-rate modulation from LFO 2, add a touch of haze or brightness to taste with the added highs control, and then mix the sum into your signal with the very sensitive dry/wet knob. These are obviously not revolutionary means of control, but the way they work on the Wind Through the Trees feels surgical and gives you a real sense of command where some flangers feel monochromatic or purely chaotic.
But if chaos—or at least the surreal—is what you crave, the Wind Through the trees can deliver. For instance, very effective, weird-but-musical textures can be crafted by dialing closely adjacent but just offset rate and depth settings in the two LFOs, then setting their respective manual (or waveform delay) controls in opposition and cranking the regen to extra whooshy levels. Using the same scheme but mixing slow and fast rate settings in the two LFOs yields even stranger and more complex variations that combine hints of rotary speaker and ring modulation. And backgrounding these wild combinations by subtracting high end and using a dryer mix adds mysterious animation to chords and melody lines.
The Verdict
At about 350 bucks, the Wind Through the Trees is the most expensive of the new PRS pedals. And it’s understandable that some might perceive that price as high for an effect that’s, ostensibly, specialized. But the Wind Through the Trees proves how expansive a flanger can be when done right. There are lovely chorus-like sounds, plenty of intense vintage phase tones, and the deep but elegant and intuitive control set makes crafting complex modulations feel effortlessly creative.
Players accustomed to presets on a pedal with such broad capabilities may be bummed by their absence. And it’s true that moving between vastly different flange settings in the midst of a performance won’t always be a piece of cake. But in the context of song creation and in the studio, where you have the luxury of hunting for the perfect modulation color, Wind Through The Trees can be a potent musical companion.

The luthier’s stash.
There is more to a guitar than just the details.
A guitar is not simply a collection of wood, wire, and metal—it is an act of faith. Faith that a slab of lumber can be coaxed to sing, and that magnets and copper wire can capture something as expansive as human emotion. While it’s comforting to think that tone can be calculated like a tax return, the truth is far messier. A guitar is a living argument between its components—an uneasy alliance of materials and craftsmanship. When it works, it’s glorious.
The Uncooperative Nature of Wood
For me it all starts with the wood. Not just the species, but the piece. Despite what spec sheets and tonewood debates would have you believe, no two boards are the same. One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.
Builders know this, which is why you’ll occasionally catch one tapping on a rough blank, head cocked like a bird listening. They’re not crazy. They’re hunting for a lively, responsive quality that makes the wood feel awake in your hands. But wood is less than half the battle. So many guitarists make the mistake of buying the lumber instead of the luthier.
Pickups: Magnetic Hopes and Dreams
The engine of the guitar, pickups are the part that allegedly defines the electric guitar’s voice. Sure, swapping pickups will alter the tonality, to use a color metaphor, but they can only translate what’s already there, and there’s little percentage in trying to wake the dead. Yet, pickups do matter. A PAF-style might offer more harmonic complexity, or an overwound single-coil may bring some extra snarl, but here’s the thing: Two pickups made to the same specs can still sound different. The wire tension, the winding pattern, or even the temperature on the assembly line that day all add tiny variables that the spec sheet doesn’t mention. Don’t even get me started about the unrepeatability of “hand-scatter winding,” unless you’re a compulsive gambler.
“One piece of ash might have a bright, airy ring, while another from the same tree might sound like it spent a hard winter in a muddy ditch.”
Wires, Caps, and Wishful Thinking
Inside the control cavity, the pots and capacitors await, quietly shaping your tone whether you notice them or not. A potentiometer swap can make your volume taper feel like an on/off switch or smooth as an aged Tennessee whiskey. A capacitor change can make or break the tone control’s usefulness. It’s subtle, but noticeable. The kind of detail that sends people down the rabbit hole of swapping $3 capacitors for $50 “vintage-spec” caps, just to see if they can “feel” the mojo of the 1950s.
Hardware: The Unsung Saboteur
Bridges, nuts, tuners, and tailpieces are occasionally credited for their sonic contributions, but they’re quietly running the show. A steel block reflects and resonates differently than a die-cast zinc or aluminum bridge. Sloppy threads on bridge studs can weigh in, just as plate-style bridges can couple firmly to the body. Tuning machines can influence not just tuning stability, but their weight can alter the way the headstock itself vibrates.
It’s All Connected
Then there’s the neck joint—the place where sustain goes to die. A tight neck pocket allows the energy to transfer efficiently. A sloppy fit? Some credit it for creating the infamous cluck and twang of Fender guitars, so pick your poison. One of the most important specs is scale length. A longer scale not only creates more string tension, it also requires the frets to be further apart. This changes the feel and the sound. A shorter scale seems to diminish bright overtones, accentuating the lows and mids. Scale length has a definite effect on where the neck joins the body and the position of the bridge, where compromises must be made in a guitar’s overall design. There are so many choices, and just as many opportunities to miss the mark. It’s like driving without a map unless you’ve been there before.
Alchemy, Not Arithmetic
At the end of the day, a guitar’s greatness doesn’t come from its spec sheet. It’s not about the wood species or the coil-wire gauge. It’s about how it all conspires to either soar or sink. Two guitars, built to identical specs, can feel like long-lost soulmates or total strangers. All of these factors are why mix-and-match mods are a long game that can eventually pay off. But that’s the mystery of it. You can’t build magic from a parts list. You can’t buy mojo by the pound. A guitar is more than the sum of its parts—it’s a sometimes unpredictable collaboration of materials, choices, and human touch. And sometimes, whether in the hands of an experienced builder or a dedicated tinkerer, it just works.
MT 15 and Archon 50 Classic amplifiers offer fresh tones in release alongside a doubled-in-size Archon cabinet
PRS Guitars today released the updated MT 15 and the new Archon Classic amplifiers, along with a larger Archon speaker cabinet. The 15-watt, two-channel Mark Tremonti signature amp MT 15 now features a lead channel overdrive control. An addition to the Archon series, not a replacement, the 50-watt Classic offers a fresh voice by producing retro rock “classic” tones reminiscent of sound permeating the radio four and five decades ago. Now twice the size of the first Archon cabinet, the Archon 4x12 boasts four Celestion V-Type speakers.
MT 15 Amplifier Head
Balancing aggression and articulation, this 15-watt amp supplies both heavy rhythms and clear lead tones. The MT 15 revision builds off the design of the MT 100, bringing the voice of the 100’s overdrive channel into its smaller-format sibling. Updating the model, the lead channel also features a push/pull overdrive control that removes two gain stages to produce vintage, crunchier “mid gain” tones. The clean channel still features a push/pull boost control that adds a touch of overdrive crunch. A half-power switch takes the MT to 7 watts.
“Seven years ago, we released my signature MT 15 amplifier, a compact powerhouse that quickly became a go-to for players seeking both pristine cleans and crushing high-gain tones. In 2023, we took things even further with the MT 100, delivering a full-scale amplifier that carried my signature sound to the next level. That inspired us to find a way to fit the 100's third channel into the 15's lunchbox size,” said Mark Tremonti.
“Today, I’m beyond excited to introduce the next evolution of the MT15, now featuring a push/pull overdrive control on the Lead channel and a half-power switch, giving players even more tonal flexibility to shape their sound with a compact amp. Can’t wait for you all to plug in and experience it!”
Archon Classic Amplifier Head
With a refined gain structure from the original Archon, the Archon Classic’s lead channel offers a wider range of tones colored with gain, especially in the midrange. The clean channel goes from pristine all the way to the edge of breakup. This additional Archon version was developed to be a go-to tool for playing classic rock or pushing the envelope into modern territory. The Archon Classic still features the original’s bright switch, presence and depth controls. PRS continues to stock the Archon in retailers worldwide.
“The Archon Classic is not a re-issue of the original Archon, but a newly voiced circuit with the lead channel excelling in '70s and '80s rock tones and a hotter clean channel able to go into breakup. This is the answer for those wanting an Archon with a hotrod vintage lead channel gain structure without changing preamp tube types, and a juiced- up clean channel without having to use a boost pedal, all wrapped up in a retro-inspired cabinet design,” said PRS Amp Designer Doug Sewell.
Archon 4x12 Cabinet
As in the Archon 1x12 and 2x12, the mega-sized PRS Archon 4x12 speaker cabinet features Celestion V-Type speakers and a closed-back design, delivering power, punch, and tight low end. Also like its smaller brethren, the 4x12 is wrapped in durable black vinyl and adorned with a British-style black knitted-weave grill cloth. The Archon 4x12 is only the second four-speaker cabinet in the PRS lineup, next to the HDRX 4x12.

The Austin-based guitarist sticks with a tried-and-true combo of American guitars and British amps.
If you’ve been on the path of this spring’s Rhett Schull/Zach Person tour, you’ve been treated to one of the coolest rock ’n’ roll double bills criss-crossing North America this year. Person, who is based in Austin, put out his second full-length record, Let’s Get Loud, in March 2024, and it was packed with alt-, blues-, and psychedelic-rock anthems built around his take-no-prisoners playing.
This year, Person is road-doggin’ it around the United States as a two-piece unit with just a drummer, and PG’s Chris Kies caught up with him before he and Shull played the Eastside Bowl in Madison, Tennessee, to see what goods Person is bringing for this spring’s shows.
Brought to you by D’Addario
Customized Custom
This Gibson Jimi Hendrix 1967 Custom SG came from Gibson’s custom shop, and for Person, an SG with humbuckers is a hard combination to beat. He removed the Maestro trem system and had a tailpiece installed for tuning stability on the road, and he subjected the neck humbucker to a “Jimmy Page mod,” which entails removing the pole pieces to get closer to single-coil tones. This SG stays in standard tuning, with Ernie Ball or D’Addario strings (usually .010–.046s). Person digs Dunlop Flow Grip .88 mm picks.
Brown Sound
Person brought this 1967 Gibson SG Special back to life with a list of modifications and upgrades, including new pickups and a refinish, but its wood, neck shape, and original frets all made it worth it to him. The neck shape is narrow but chunky in Person’s hands, landing somewhere near the feel of Tyler Bryant’s 1962 Stratocaster. The pickups now are OX4 P-90s, and like the Custom, this one’s had its Maestro system amputated.
Jeannie Comes Alive
One Thanksgiving at his in-laws’ home in Dallas, Person mentioned how badly he wanted a Gibson LG-2 acoustic. As it happened, his father-in-law suspected his mother had one, which had been relegated to storage in a shed. Person and his wife’s father ventured through rain to dig it out, and sure enough, a very beat up LG-1 was withering away in its case. No local techs in Austin thought it was worth saving, except for Elaine Filion, who was used to taking on bigger restoration projects. Filion succeeded, taking the top off and installing an X-bracing system to turn the LG-1 into an LG-2-style guitar. Now, it’s got an L.R. Baggs pickup and bears the nameplate “Jeannie” on its headstock to commemorate his wife’s grandma, the original owner. Jeannie usually stays home, but Person brought her out specially for the Rundown.
Marshall Muscle
This Marshall JTM45 MkII is Person’s usual go-to. It runs just at breakup volume and gets pushed with some variation of a Pro Co RAT, his favorite dirt box.
Supro Signature
This Super Black Magick Reverb, Tyler Bryant’s signature, is along for the ride as a backup to the Marshall.
Zach Person’s Pedalboard
Person has done tours with just an overdrive pedal and nothing else, so by comparison, this two-tiered Vertex board is luxurious. Still, it’s compact and carries all he needs at the moment. The JHS Pack Rat is the core sound, set fairly heavy and dirty. The rest includes a Boss TU-3, EarthQuaker Devices Double Hoof, Vox Clyde McCoy wah, Boss BF-2, DigiTech Drop, Strymon El Capistan, and an Interstellar Audio Machines Marsling Octafuzzdrive. A TC Helicon Mic Mechanic rides along as a vocal effect so Person can keep control over his voice from night to night.
