Though the business of cloning pedals is competitive (and endless fodder for frothing Reddit denizens), I appreciate when a pedal company offers a useful twist on an established formula.Warm Audio accomplishes this with the Throne of Tone. It is clearly inspired by theAnalog Man King of Tone. But it is also very obviously a nod to the Marshall Bluesbreaker, the pedal that Mike Piera used as a departure point for his KOT design. The Throne of Tone, though, might mark the point at which the snake bites its tail. It cross-pollinates the circuits in a dual overdrive that opens up many, many tone-coloring avenues and options.
Split Personality
Mike Piera ripped up a friend’s Bluesbreaker to build the first King of Tone. But by the time he rewired it, it was a different pedal altogether. To the extent that the KOT and Bluesbreaker sections are accurate in the Throne of Tone, the differences between the original Bluesbreaker and King of Tone are easy to hear. It’s hard to accurately assess the accuracy of the Throne of Tone’s two circuits without a real-deal King of Tone or Bluesbreaker at hand. But I’ve played through both as well as excellent clones, and in both sound and feel, both Throne of Tone circuits are in the ballpark and better.
In very general terms, that means the “king” side is a bit less aggressive, darker, and more dynamically responsive to changes in pick intensity—especially when you want to go from gnarly to truly clean. The “blues” side is a bit more dynamite, revved up, and lively in the midrange. It’s more immediate and a bit harder to keep on a leash for dynamic purposes. But the Throne of Tone is a great multiplier—and mixer—of these qualities, because you can experience each basic voice through the lens of high gain and low gain settings, a boost, an overdrive or a distortion. Additionally, output from each side can be modified with a presence control which appears on neither pedal in its original form. Add up the possible tone permutations and, well, you’ll probably be less occupied with the accuracy of the circuits, and more excited about harnessing the copious killer tones here.
Pick A Door
Of the three modes, the boost is the most user friendly and easy to apply to a base tone that just needs heft and body. It’s also great for demonstrating the basic duality in the king and blues voices—which align along a Marshall/Fender divide. The blues, or Marshall-like side feels considerably more compressed as a boost, but it positively rings in the high-mid zone. If you want a guitar to be boss in a mix it dishes the goods. But it’s agreeable too, and flattered PAFs, Telecaster single-coils, Wide-Range humbuckers, and a Rickenbacker 12-string—lending all of them an infectious, excited edge. Matched with an EL84 amp it can feel a touch redundant, but with 6L6 amps it shines. The king, or more Fendery side, sounds comparatively scooped. It feels much less hyperactive, and it excels in the clean, low-gain range, but it also gets squishy when you dig in.
These same qualities are very apparent in the overdrive mode. Each voice sounds more compressed than the boost mode. But the higher reaches of the gain controls yield treasure. Here again, the blues side was explosive—sounding at many settings like Malcolm and Angus Young after consuming a bag of firecrackers. Angry but fun. The king’s OD side, at high gain range, sounds much more like a mid- to late-’60s Bassman at high volume: crunchy, but softer around the edges. Each of these voices can be nudged into more savage extremes by the high-gain toggle, which depending on your amp and guitar, can be surprisingly airy to downright sizzly.
The distortion mode kicks the high-midrange in the pants, but retains much of the overdrive mode’s basic coloration. It’s an especially cool match for 6L6 amps—especially on the king side. But the way the distortion modes remain responsive to dynamic input like volume and touch variation is impressive. Distortions can often sound quite binary—either raging or gobbling up midrange oxygen. Both distortions in the Throne of Tone give you gray area to work with that can range down to chiming clean tones.
The Verdict
The original King of Tone and Bluesbreaker pedals are revered for good reason. And if Warm Audio’s take on the two circuits represents even 80 percent of those pedals’ prime tonality, you’ll still hear and feel what makes them special. As a whole, the Throne of Tone is adaptive and versatile. The kind of pedal that could save your hide and solve problems in a studio. But it could work the same magic in a live situation, especially one with a backline surprise in store. In performance, the vertically oriented mini toggles, which are situated perilously close to the bypass switches, could be a liability. I accidentally switched the gain and mode switches with my toe more than once. That’s a shame, because they make experimentation so much easier than when DIP switches are in the mix. It’s hardly a dealbreaker, though. For $229, the Throne of Tone offers a very big bucketful of tone options that can span civilized and rabid.

Attack—essentially the rate and intensity with which a note rises in volume from its point of creation—is one of the coolest musical expressions you can mess with. If you play an instrument from the violin family it’s a fundamental part of your vocabulary. It’s used frequently in synthesis to conjure spooky, low-gravity atmospherics, and it’s an essential tool for taking the front end off some psychotic Moog sound that might otherwise explode like a foghorn six inches from your ear.
Guitar players know the potential of this effect well too. Volume swells can drastically recast a guitar line—evokingreverse tape,pedal steel, and deep space. But doing it well is not easy. Even on guitars like theStratocaster that lend themselves to volume swells by design, it takes technique, practice, and usually a very flexible pinky finger to make it work right. Electro-Harmonix’s Swello, which has origins in the attack filter section of the POG2, can do a lot of that work for you. But it’s capable of more than simple swells, with the ability to generate envelope filter- and wah-like sounds, big synth-style pads that are ripe forlooping, and much stranger fare.
Swing in Smoothly
Though they can be mellowing, soft attack and volume swell effects aren’t always subtle. For many players that prize precise, immediate attack, they are anathema. Swello—especially in the sans-filter “green” mode—is great at backgrounding the effect and making it more subliminal. At the lowest attack levels, you can use Swello in a capacity similar to a compressor to soften picking irregularities. At slightly higher but still subtle settings, it imparts a beautiful legato quality to melodic lines—especially enchanting in understated or deeply ambient delay and reverb contexts. At much slower attack rates, it evokes lush pedal steel tones and remarkably natural volume pedal or cello-like effects. There’s a lot of range to explore in the attack control alone.
"Swello ’s capable of more than simple swells, with the ability to generate envelope filter- and wah-like sounds, big synth-style pads that are ripe for looping, and much stranger fare."
While the Swello’s control set is minimal, players without experience in synthesis or in using filters and envelopes with guitar may find them less than intuitive. This isn’t a shortcoming of the EHX design—it’s simply inherent to the complex interplay between filter and attack effects. If you start twisting knobs casually and with no particular intent you can end up with filter and attack combinations that make a guitar sound 30 feet underwater—if not altogether absent. So, it pays to move slowly though these controls, observe the sensitivities in their interactions and pay attention to how very small, incremental changes—as well as where you play on the fretboard—can alter the response and output. Though getting to your destination can be tricky and require patience, there are many surprises to find along the way.
Overtone Organizer
As a player that uses volume swells as both an expressive tool and crutch, I loved Swello’s very natural volume pedal and cello-like effects. But I also own a POG2 and treasure that pedal’s capacity to add -2-octave content to an upswelling tone. That can be a preposterously big sound with reverb (the low synth parts in Vangelis’ Blade Runner opening sequence and the Golden Gate Bridge foghorn at the distance of a couple miles are a couple handy points of reference). And there’s plenty of it here when you get a deep resonant peak, slow attack, and filter modulation working in sync, and hang out on the low strings.
As with the POG2, boosting the high frequencies can make the pedal sound less organic—and at times even a bit cloying. Some settings also introduce digital artifacts, most noticeable in the quackier, mid-forward envelope filter-style tones. These sounds can be fun, but they’re not the Swello’s strong suit (and may disappoint players that demand vintage Mu-Tron authenticity from envelope filters). That said, there are plenty of ways to use high-frequency emphasis for pleasant coloration and to shape the attack, and at many such settings the output is largely free of digital aftertaste.
The Verdict
Swello, as the name suggests, specializes in very cello-like volume swells that sound organic, and enable you to keep your fingers on the strings and your feet away from expression pedals. At less than $150, it’s a great value for the slow-attack effects alone. However, players who explore its compression-like dynamics and the vast, unconventional tones found at atypical filter frequency and modulation settings will discover that the Swello is far more than it appears—truly greater than the sum of its parts.
Since it was first introduced in 1958, Vox has released myriad iterations of the AC15 combo—built variously in England and Asia, and offered in both hand-wired and PCB formats. The new AC15 Hand-Wired suggests a strictly old-school ethos, but several of its features—most notably a move from EF86 to 12AX7 preamp tubes—are deviations from vintage form. That does result in a different feel in some situations; at times it sounds and feels more like a half-power, 1x12 AC30 than a vintage AC15. But this iteration is arguably more flexible than its predecessor, too.
Channel Crossing
Given the microphonic tendencies of EF86 tubes, the switch to 12AX7s is an intriguing and practical move. Elsewhere among the tube complement, there’s a 12AT7 for the preamp and phase-inverter, two EL84s in the output stage for 15 watts RMS, and a GZ34 tube rectifier. It’s all housed in a classic Vox combo cab measuring 22 1/4"x23 1/4"x1 1/2".
The AC15 Hand-Wired’s normal channel has just a single knob for volume. But its voicing can be tweaked via a bright switch and the tone cut knob in the master section, and there’s also a boost switch to increase gain. The top boost channel features volume and dedicated treble and bass controls, but no boost or bright switch. Both channels have high and low inputs, and the latter can be handy for taming hot humbucker-equipped guitars.
The fine-tuning capabilities of the amp extend to the footswitchable, tube-driven, spring reverb circuit, which has a tone control in addition to its level, enabling you to fine-tune the frequency emphasis of the reverb itself. Send and return jacks for the effects loop—along with a bypass switch and a –10/+4 dB level switch for compatibility with both rack and pedal effects—are smartly positioned along the lower edge of the upper-back panel, rather than on the underside of the chassis. Dual speaker-outs have an impedance switch for 8- and 16-ohm operation. (The combo’s Vox-labeled Celestion Alnico Blue requires the latter.)
Vox was careful to reproduce the windings of a vintage AC15 output transformer circa 1963, which results in a heftier chunk of metal than you might expect in an amp this size. Vox makes up some of that weight by using slightly thinner plywood for the cabinet walls, which are just less than 1/2" in thickness—matching vintage specifications and, in Vox’s estimation, enhancing resonance and dimensionality. As with many AC15s past, the transformer and alnico speaker help push this new edition to 50 lbs, making for a surprisingly heavy combo of this size and output power. It might have been nice for Vox to slim things down. On the other hand, the amp might lose what turns out to be a strong, audible vintage spirit without those heavier design elements.
Chiming In
Paired with a Gibson ES-335 and a FenderTelecaster, the AC15 Hand-Wired plated up many impressive slices of vintage Vox tone, with plenty more versatility on top. With all knobs at noon and the boost and bright switches on the normal channel engaged, the two channels sound remarkably similar. There might be just a touch more grind and sparkle on the top boost side, but it’s close! At these levels, both channels still summon plenty of break up with a Telecaster. Switching to the ES-335’s humbuckers predictably kicks the overdrive up a notch at the same settings.
The boost switch on the normal channel isn’t always a breeze to manage. It delivers a pretty big jump in gain and, with it, a slightly ragged edge at some settings. With both boost and bright switches down, though, the normal channel is rich, warm, and muscular, and makes an excellent, adaptable platform for gain pedals (in my case an Analogman Prince of Tone and a Wampler Tumnus Deluxe). Knock this normal channel volume up to around 2 o’clock and it segues into toothsome sounds that dip into clipping under heavier pick attack.
Arguably the most delectable tones are found in the top boost channel with all three knobs set to around 11 o’clock. Here, the AC15 Hand-Wired achieves its closest approximation of vintage Vox tone: chewy midrange, lots of chime and sparkle in the highs, and a dynamic edge-of-breakup touch sensitivity that you can control and vary via pick attack. Cranked up, the top boost channel roars with a throaty, shimmery vintage lead tone, although at the expense of the delectable dimension and clarity achieved at lower volumes.
The amp’s master volume, by the way, is very effective at tailoring the AC15 Hand-Wired for a range of room requirements, and is essential for smaller venues. This amp is loud when maxed—probably a lot louder than you’d expect from a 15-watt 1x12" combo—which is another classic characteristic of the AC15. It’s worth noting that things can get a little ratty with the master below 10 o’clock and either channel volume up high, but that’s par for the course with such circuits.
The Verdict
Vox’s new AC15 Hand-Wired combo does a good job of capturing much of the vintage-voiced spirit of the classic while offering many features that are must-haves for modern guitarists less burdened by complete vintage correctness. And if it’s not a point-perfect reproduction, it honors the sound and spirit of the original—and looks the part onstage, too.
Khruangbin is a band that moves freely in negative space. They don’t deal in negative vibes, mind you, but the spaces in between objects—or in music, between notes and tones. In Khruangbin’s case, negative space isn’t quite as empty as it seems. In fact, a lot of it is colored with reverberated overtones, which is an aesthetic well suited to Mark Speer’s instrument of choice. Because if you want to color negative space without being a space hog, there are few better means than a Stratocaster.
Speer’s signature Stratocaster, is not, in the strictest sense, a classically Strat-like specimen. Its bridge and neck pickups, after all, are DiMarzio Pro Track humbuckers, with a design informed more by PAFs than Fender single coils. Nor is it modeled after a priceless rarity. Speer’s main guitar is a humble ’72 Stratocaster reissue from the early 2000’s. But the Speer signature Stratocaster is a thought-provoking twist on classic “Stratocaster-ness,” and one well-suited to the atmospherics that mark Khruangbin’s music, but also soul, reggae, jazz, and any other expression where clarity and substance are critical.
Mr. Natural Takes It In Stride
I have to admit—and no doubt some of you will disagree—for most of my life, as an early- to mid-1960s-oriented aesthete, an all-natural-finished Strat with an oversized headstock looked flat-out wrong. My opinion on the matter has softened a bit since. And I think the Speer Stratocaster is beautiful, elegant, and does much the flatter the Strat profile. The pronounced grain in the ash body is lovely, and it certainly doesn’t reflect the drop in ash quality that many feared when ash-boring beetles started to decimate swamp ash supplies. It also looks great against the milk-white single-ply white pickguard and all-white knobs (another nice study in negative space).
Elsewhere, many features are authentically 1972. The 1-piece, 3-bolt maple neck with a 7.25" fretboard radius boasts a micro-neck-adjust feature as well as the practical and cool-looking bullet truss rod. The tuners also feature early ’70s-styled machine covers. The neck itself feels great—slightly less chunky, perhaps, than early ’70s Strats I’ve played, and, oddly, not worlds apart from the neck on my Mexico-made ’72 Telecaster Deluxe, which has a much flatter 12" radius. Some of the similarities in feel may have to do with the jumbo frets, which here give the gloss urethane fretboard a slinky, easy touch. Less delicate players (like me) who tend to squeeze when chording should check out the Speer before purchasing to make sure they don’t pull everything sharp. The frets do make string bends feel breezy, though. Other details, apart from the jumbo frets, that deviate a bit from 1972 Fender spec include a bone nut and Graphtec saddles and string trees.
Warmth of the Sun
The DiMarzio Pro Tracks dwell in an interesting tone space. They’re built with ceramic magnets (vintage Strat and Gibson PAFS were made with alnico magnets) with a resistance of about 7.7 k ohms, which is in the range of a vintage PAF humbucker but hotter than most vintage Stratocaster pickups. In terms of tone signature, they sound and respond a little more like PAFs than Stratocaster pickups, too, which aligns with DiMarzio’s design objectives. But in the neck pickup in particular, the Strat-iness is very present. And when I switched back and forth between a Stratocaster and PAF-equipped SG as baselines for comparison, I marveled at how well the DiMarzios retained qualities of both. It’s hard to know how much Fender’s 25 1/2" scale factors into lending the extra bit of Fender color. But the sound is distinctly, authentically, Speer-like. (For the record, I replicated much of Speer’s circa 2018 signal chain for this test, including a Fender Deluxe Reverb, Dunlop Cry Baby, Boss PH-3 and DS-1, MXR DynaComp, and a Echoplex-style pedal).
The PAF qualities of the DiMarzios are most pronounced in the bridge pickup, which is much burlier and thicker than a Stratocaster single coil. The one single coil on the guitar meanwhile, the middle pickup, will sound and feel familiar to any old-school Stratocaster player. It’s also perfect for chasing Jerry Garcia tones if you’re selecting the Speer for its likeness to Jer’s “Alligator.” The real treat among the Speer’s many sounds, though, is the number 4 position, which combines the neck pickup and middle pickup out of phase. It’s snarky, super-focused, and just a little bit nasty, especially with overdrive and treble bump from either a wah, OD, or boost pedal.
The Verdict
For those players who fall in love with the comfort, feel, and looks of a Stratocaster, only to find it a bit thin-sounding for their purposes, the Mark Speer Stratocaster is an intriguing option. The humbuckers deftly thread the needle between Stratocaster and PAF tonalities, with a distinct lean toward the latter, and the out-of-phase number 4 position is a cool sound that lends the Speer Strat expansive smooth-to-nasty range. Like so many Mexico-made Fenders, the quality is superb. And while the $1,499 price tag represents a Signature Series bump compared to the similar $1,209 Vintera II ’70s Stratocaster, the Speer’s extra tone range and ash body do a lot to soften any sticker shock. If the options here fit your style, it could be well worth the extra dollars.
