With a tone vocabulary that spans clean, smoky, grinding, and growling—plus a Two notes speaker simulator—the 25-watt Airwave is a ferociously fun, potentially formidable amp for any size stage or studio.
Needless to say, the splashy news about Supro’s Airwave is its onboard Two notes cab sim that expands the amp’s studio and live capabilities, not to mention a player’s creative options. Having Two notes cab simulations onboard is a cool thing. It takes many of the cab sim tailoring capabilities of, say, the Universal Audio OX or Boss’ WAZA Tube Expander, and makes them part of the Airwave’s amp architecture, which is no small victory for convenience.

But the 2x6V6 Airwave is a very cool stage and studio amp before you ever touch the cabinet simulation capabilities. At 25 watts, with tube-driven tremolo and spring reverb, it’s a cool alternative for players considering a tweed Deluxe, Deluxe Reverb, Princeton Reverb, or, for that matter, any of Supro’s excellent low- to mid-power combos. But while it’s not quite the blank slate a Deluxe Reverb is (the Airwave’s voice is generally more compressed, with lower headroom), if I had to record or play a show with the Airwave, a delay pedal, and a guitar, I’d do so confident that I had about 4-zillion awesome, tender-to-gnarly textures to work with.
Little Basher
The Airwave is a handsome amp, designed with lots of vintage Supro motifs, a wide aluminum control panel, rocker switches, and a control layout that are more than a little evocative of the Rolling Stones’ early Ampegs. There’s also a little Stones swagger in its voice. For while it can do a very convincing approximation of bright, almost-cleanish Princeton Reverb or Deluxe Reverb sounds, it’s basically grittier than either of those. Not in a way that confines the Airwave to garage-rock trash realms, but which hints at sepia-tone speaker sounds and a loud, rowdy vintage Supro or tweed Fender edge when you dig in with a flatpick. These savage-around-the-edges facets of the Airwave’s personality are tempered, perhaps, by the 12'' speaker, which adds thickening counterpoint to the barky midrange growl and enhances bass frequencies. It helps make the 3-band EQ section feel more sensitive and interactive, too.
The tone variations available between just the EQ and master volume/gain control interplay are plentiful. But all those sounds can be dramatically recast and even made electrifyingly aggressive with the onboard, switchable boost and drive, which are activated by the two rocker switches on the front panel or optional footswitches.
Alternate Realities
To interface with the Airwave’s Two notes capabilities, you download the Torpedo Remote app. But you can obtain excellent sounds without going deep, thanks in part to the amp’s onboard boost and drive switches. They feel like pedals perfectly selected to work with the amp and each other. The drive in particular is tough and snarling. And though your results may differ, to me the effects feel organically enmeshed in the fabric of the amp’s output. Both effects can be gritty, punchy, and explosive extensions of the amp, and together they can make it sound huge for 25 watts. The Torpedo Remote app calls up more-or-less photorealistic representations of several studios and live spaces (ancient temples included!), microphones, and cabinets. As in many other cab sim applications, you can readily and easily change microphones, slide microphone positions back and forth, switch between virtual cabinets of various sizes, as well as add preamps and reverbs with easy-to-use analog-style interfaces. If the wealth of sounds here isn’t already everything you need to get a great recorded sound, they get you off to a great start. What’s important, though, is how seamlessly they function with the whole range of the amp’s tones.
The Verdict
Although $1.5K might seem like a lot to pay for an Indonesia-built tube amp, it’s noteworthy that amps like the Fender ’65 Deluxe Reverb reissue are now pushing the $1.8K barrier. But the Airwave includes a useful and well-integrated Two notes Torpedo cab sim solution worth several hundred dollars by itself. Most impressively, Airwave excels in both the purely analog and digital cab sim realms without compromising capabilities in either. The amp has loads of personality and range. It’s up for a punky Kinks/Ramones rumble or Alvin Lee rippage, but just as eager to please as a clean-cut extra in a Jaguar-and-spring-reverb surf party flick or vintage soul session. If you’re the kind of artist inclined to do a little of all that in your recording and performing life, the Airwave satisfies on every count.
Andy Powers’ influence on the substance and style of Taylor guitars has been truly significant. Over his 14-year tenure leading Taylor’s design efforts, he’s introduced entirely new bracing patterns and body profiles—never easy when working for a legacy brand in a tradition-oriented industry. In crafting the new Gold Label 814e Koa Super Auditorium, Powers might have created Taylor’s prettiest body shape yet—a blend of sweeping curves, airy lines, and graceful proportions that, like a river stone, appear as if shaped by water.
Stylish, for sure. But there’s substance in abundance, too. The ever-tinkering Powers reconfigured the V-Class bracing Taylor introduced in 2018 for the new Gold Label 814e guitars. There’s also a new glue-free long-tenon neck—significant news considering how large Taylor’s NT neck looms in the company’s identity. What’s interesting about those moves is that Powers was keen to bake a visceral sense of vintage-ness into this guitar. The Gold Label 814e doesn’t sound much like the old American flattops I run into, but it’s distinguished by sweetness, clarity, balance, and expressive range.
Presence and Proportions
The Super Auditorium body shape that debuts with the Gold Label 814e is a close relative of Taylor’s lovely Grand Auditorium shape, which, at 30 years old, is now a foundational part of Taylor’s line. In fact, the 814e Koa is just 3/16" longer and 1/4" wider than a Grand Auditorium. More obvious is the absence of a cutaway, and the symmetry of the curves highlight lovely, just-about-perfect proportions. It’s a beautiful guitar, but it’s probable the increase in dimensions has more to do with Powers chasing a specific sound. Certainly, more size could align with aspirations to the antique tone glow of a vintage American flattop.
The collective effect of the body dimensions (which live in a sweet spot between grand Concert and dreadnought size) and the modified V-Class bracing means the Gold Label 814e’s voice is distinctive rather than overtly “vintage” (a broad, unspecific term at best). At the risk of disappointing Powers and Taylor, I think the Gold Label 814e exhibits many classically Taylor tone attributes to excellent effect, and the snappy midrange and relatively even string-to-string balance at times evoke an acoustic that’s been EQ’d and compressed by a recording engineer. But what will resonate for many players is the way the Gold Label 814e complements the modern facets of its voice with toasty bass from the 6th string and a little less top-end brilliance from the 1st and 2nd strings—qualities you’re more likely to hear in a guitar with 70 years of toil baked in. In the Gold Label 814e, those tonalities are bookends for a broad midrange that is very present and very Taylor, and whether that whole suits your playing style has a lot to do with how much you can leverage its impressive dynamics. Heavy-handed strumming confirms that the Gold Label 814e is capable of being very loud. It also highlights a pronounced midrange that, for all the guitar’s string-to-string balance, can be a bully if you have a heavy touch. If your approach is more varied and sensitive, though, the extra volume becomes headroom and the midrange becomes a chrome shine set against a dusty desert patina. It’s a killer recipe for fingerstyle. A light touch can still generate detailed, complex overtone pictures, while the high headroom accommodates and inspires high-contrast high-intensity counter phrasings. There’s a lot of room to explore.
Grease the Runway
Playability is, as expected, a strong suit. The action feels extra-easy and encourages hyperactive playing styles as well as languid chording that utilizes the instrument’s sustain, range, and rich pianistic qualities. The 1:21 ratio Gotoh 510 tuners feel ultra-precise, making moves between alternate tunings easy and enhancing an already strong sense of performance stability. Flawless fretwork, meanwhile, feels fantastic and underscores Taylor’s super-high quality. A fatter neck profile certainly would have suited me, and even though you can feel the tiniest hint of a V-profile bump at the neck contour’s apex, it still feels a touch thin. Even so, a lack of hand fatigue and a sense of fleetness in the fingers make the trade-off worthwhile.
Appropriately, for a guitar that costs $4.8k, the Gold Label 814e is a feast for the eyes, but in a sneaky, not-too-extroverted kind of way. The Hawaiian koa back and sides, which are a $300 upcharge from the rosewood-backed 814e, are, along with the Continental inlays, the flashiest element of the instrument. And though the high-quality lumber elsewhere in the guitar (torrefied spruce top, ebony fretboard, mahogany neck, ebony tuning keys) all feel luxurious, the deeply figured koa adds an extra splash of bespoke flash. Seasoned Taylor spotters will also note that the lines of the koa sides are not cluttered with the controls of the Expression System 2 electronics, which have been replaced here by an excellent L.R. Baggs Element VTC system that utilizes controls tucked inside the soundhole.
The Verdict
Though the 814e Koa aspires to 1940s and ’50s American flattop vintageness, it doesn’t always deliver on that count. For the right player, though, the instrument offers a unique and complex voice with a super-wide dynamic range and soft-focus bass and treble tones that temper the midrange. The new glue-free, long tenon neck can be reset fast and inexpensively should that time ever come, which might make the sting of the hefty $4,799 investment feel less risky—at least in maintenance terms. Yep, it’s really expensive. But consider, too, the joys of beholding the 814e Koa’s graceful curves all day—you might be able to justify the cost as a musical instrument as well as art.
Wanna talk about rabbit holes? Well, few are deeper or darker than one that awaits when you compare the virtues, shortcomings, and construction peculiarities of Big Muffs. Make no mistake, I love the things. And studying real, audible differences among Big Muff variants is fun. But I would happily take back many hours I’ve spent contrasting Ram’s Head, Triangle, and Sovtek versions, and their clones—all to arrive at the conclusion that they all sound awesome in their own right. One dude that has spent about a million hours dissecting Muff tone minutiae is EarthQuaker Devices founder Jamie Stillman. Hisefforts to reverse engineer his pal Dan Auerbach’s unique-sounding Sovtek Muff begat theHoof, which remains among EarthQuaker’s most enduring and successful products.
Just as Auerbach’s Muff possessed a certain something missing in otherwise identical Sovteks, so it was with a Version-6 (V6) Electro-Harmonix Big Muff used by James Murphy of LCD Soundsystem for his band’s fuzz-bass tones. As 40-something pedals will, Murphy’s V6 Big Muff got a bit fussy for tour life, so Stillman and EQD were tasked with crafting a replacement. But like so many vintage pedals that have become notorious and legendary, Murphy’s V6 Big Muff is distinguished by construction inconsistencies that made it a quirky and unique thing.
EQD’s interpretation of this formula—made manifest here in the Chelsea Low End Fuzz Driver—is a Big Muff-style voice that leans more Ram’s Head than Sovtek. In strictly sonic terms, that means lots of grind, presence, and a delectable balance between air and aggression that make the Chelsea soar. Like a vintage V6 Big Muff, it features a tone-bypass switch which removes the tone pot entirely. The midrange-heavy result is appealing and impressive in its own punky way. But the rangeful tone control, and the oxygenated sounds that live in its treblier zones, in particular, are highlights of the pedal’s vocabulary that make it distinctive.
As the “Low End Fuzz Driver” handle and Murphy’s historically bass-oriented usage suggest, the Chelsea’s tone profile is a great tool for crafting gnarly, nasty, bottom-end sounds that have a trace of almost saxophone-like honk and grit on top of mere mass—a sound composite that gives bass and baritone riffs lift and definition. But as sweetly and swaggeringly as the Chelsea gels with bass, guitarists will find it a source of rich and blistering tones, and a distinctive alternative to early Triangle-, Ram’s Head-, and V6-style Big Muff sounds.
It’s easy to characterize Chase Bliss' Joel Korte and “Analog” Mike Piera as pedal-designer opposites. Piera’s work is rooted in understanding what makes great vintage circuits special and building improved, refined, better-quality versions. Korte is often a maximalist (many sounds, many knobs, many possibilities) and an envelope-stretching modernist (unorthodox tones, digital control). But the two builders share much in common. Both are gifted designers, and each is tireless—perhaps obsessive—about chasing specific sounds. The intersections in their methodologies are embodied in the Brothers AM, a Chase Bliss/Analog Man collaboration based on the scarce and much-coveted Analog Man King of Tone dual-gain device.
The Brothers AM nails the creamy, clear, and agreeable essence of the KOT—at least what I know of it. Like many of you, I do not own a KOT and rely on the effusive raves from fellow musicians and what I’ve heard live and in the video sphere. But you don’t need a KOT to hear how good the Brothers AM is. It’s an excellent drive pedal by any comparison. The seamlessly integrated dual-circuit design means it moves readily from very subtle to very vicious tones. It’s even more versatile than its inspiration, thanks to the inclusion of an addictive, dynamite 2-position treble booster and DIP switches that expand the pedal’s tone palette and control options.
Rock-Solid Foundation
The original King of Tone pedal was inspired by a moddedMarshall BluesBreaker which an Analog Man client bought as a less-compressed, less-midrangey Ibanez TS9 alternative. By the time Piera completed the King of Tone, it didn’t sound much like a BluesBreaker. But it achieved other aims: It sounded natural and open and felt touch responsive. As the KOT evolved it effectively became two drive pedals in one—each of which could be configured as a boost, drive, or distortion. This KOT iteration is the foundation for the Brothers AM.
The many controls on most Chase Bliss pedals induce panic among some players. If you’re among them, Brothers AM won’t do much to calm your nerves—at least at first. In reality, though, the Brothers AM is easy to know. The six knobs are two identical sets of gain, volume, and tone controls for the two circuits. You switch each circuit between boost, OD, and distortion using two dedicated toggles on either side of the 3-position treble booster switch. The DIP switches on the pedal’s crown make it possible to add extra gain, reconfigure the footswitches for momentary bypass, repurpose volume and tone knobs as master volume and presence controls, save and switch between two additional presets, assign expression pedal control, and more.
Manifold Monster
One of the Brothers AM’s great strengths is its agreeable nature. It doesn’t seem to give a hoot what guitar or amp you throw in the pool with it. This easygoing personality makes it a great backline-surprise coping tool. Got a Telecaster and an AC15 conspiring to run you through with treble daggers? A dose of the Brothers AM’s soft-clipping OD and a dark tone setting will turn those sharp ends to honey without sapping too much energy. Need to slice through humbucker fog? A dollop of top end and a bump from the treble boost will cut through pea soup. Finding these agreeable baseline tones for a given guitar/amp combination is easy. But what’s most satisfying is shaping, refining, and recombining the Brother AM’s two basic voices into so many completely different identities.
Another great thing about the Brothers AM: You know how a lot of overdrives turn to mud at low amp volume? The Brothers AM sounds and feels great in this role. The range and interactivity between the tone and gain controls enables hot, lively tones and touch-responsive playing dynamics. The Rangemaster-voiced booster shines in this context, too. I got full-bodied, sparkling sounds from a 35-watt Fender Vibrolux whilst leaving room for an unamplified acoustic and voice in the same room. And it's easy to hear how Brothers AM will excel in small or home studios just as readily as it does in big rooms with big, loud amps.
If the Brothers AM has a drawback, it’s the heavily colored compression at the highest gain levels. But if the Brothers AM doesn’t shine brightest at these settings, the relative headroom and kinetic bump at most others underscore how you don’t need maximum gain to make your tone as hot as the hinges of Hades.
The Verdict
The Brothers AM makes almost any guitar or amp feel more alive and muscular, in shades ranging from a hint of heat and mass to fuzzy, fierce, and very loud. Though many stompbox clockers categorize the Brothers as a transparent overdrive, it does possess a compressed coloration throughout its range. It’s less cramped in the midrange than a vintage TS9, just as its creators intended. But if super-oxygenated boost-to-light-overdrive tones are the goal, you still might be better served by a good Klon clone or a preamp pedal that mixes in a clean signal. For anyone else, the Brothers AM is full of delights. It lends extra body and fullness to any tone recipe without stripping away instrument or amp personality. It’s effective in small rooms where you still want big-amp sound, but the visceral way it elevates a louder amp—especially with the thrilling treble booster in the mix—can make a player giddy. The Brothers AM, as suits its name, is like the kid at school that gets along with everyone. It doesn’t matter if you have a Rickenbacker and a Vox, an SG and a Deluxe Reverb, a baritone and a Marshall, or a decrepit old lipstick-pickup Silvertone and a Champ—all of them can sound and feel extra exciting along a spectrum that spans a gentle push and raging roar.
Xotic Effects newest version of the Vox-flavored AC Booster, the AC Booster V2, adds a second, footswitchable boost circuit (tweakable via a small, clear knob tucked among the four main-channel controls), plus a set of four DIP switches on the box’s righthand side which engage compression, modern or classic voicing, low-mid boost, and high-mid boost.
This new suite of features packs significant extra functionality into V2’s still-diminutive enclosure. The Vox sounds are all there, and with the high-mids juiced and treble nudged, you’re squarely in clanging Top Boost territory. The modern voicing trades some furry mid-range chunk for a bit more aggression and clarity, while the compression is useful for leveling leads and smoothing out unruly playing.
The boost knob is a little difficult to access, situated as it is in the center of the primary four-knob array. I don’t have particularly big fingers, but even I had trouble twiddling it. That’ll annoy some. But it’s a small price to pay for such a pedalboard-friendly footprint. The boost doses you with a healthy bump in level and gain that’s great for stand-out leads and solos. And speaking of standing out, the upper-mid boost switch is a treat. I found that creating a greater disparity between the high mids from the low mids made for a more precise and satisfying tone-shaping experience than I would experience using a standard mids knob.
There are no shortage of pedals that ape Vox AC30 mojo, but I haven’t seen many that will give you the range of utility that the AC Booster V2 will, for less for $200. Xotic nailed a smart and versatile redesign here.
