Maestro FZ-M, Comet Chorus, Invader Distortion, Discoverer Delay, and Ranger Overdrive Reviews

A classic brand’s colorful return to the stompbox fray is marked by equally vibrant sounds.
The resurrection of Maestro as a stompbox-building concern has been a real breath of fresh air. With their colorful, substantial enclosures and illuminated bugle logos, Maestro’s five new stomps recall an era when effects pedals were still, thrillingly, working through their infancy. Call them retro if you want, but they look awesome, offer practical functionality, and sound great by just about any measure.
The beauty of Maestro’s stomps runs deeper than cool, colorful enclosures. There are a lot of compelling and often distinctive sounds in these effects. And with the promise of even more new releases before the end of 2022, it’s hard to not be excited about what oddities and original sounds might lie in wait. But for now, these new cornerstone introductions suggest that Maestro is embracing the creative possibilities of an new all-analog pedal line and aiming for sounds and functionality that offer real alternatives on the more accessible side of the cost spectrum.
Maestro's Five New Pedals | First Look
FZ-M Fuzz
For more information about the Maestro pedal line, go to maestroelectronics.com.
Though much has been made about Maestro’s return to the fuzz space, the new FZ-M is a very different animal than the 3-volt, AA battery-powered FZ-1 that appeared in 1962. Maestro is tight-lipped about the FZ-M’s design particulars. But Craig Hockenberry, director of engineering at Maestro, says the FZ-M employs a six-transistor design. By comparison, the Maestro FZ-1 used just three transistors and an Electro-Harmonix Big Muff used four. Other than the beastly Shin-Ei Super Fuzz, few fuzzes use six.
While the FZ-M is not an FZ-1 reissue, Maestro captures a lot of the sonic essence of mid-’60s fuzzes like the FZ-1 that eludes other builders. In vintage mode, the FZ-M has the snarling top-end focus and rasp that makes mid-’60s fuzzes cut so prominently. There’s more gain and volume than an FZ-1, which makes the FZ-M’s voice more aligned with the silicon Fuzzrite, silicon Bosstone, and, to some extent, the MkIII Tone Bender. (Of the fuzzes I used for comparison, a silicon Fuzzrite was the closest match.) And though the FZ-M is hot in the treble zone, there is a cool high-midrange honk that adds a smooth, almost saxophone-like resonance and complexity that keeps it from sounding too sizzly.
While the FZ-M, with its silicon transistors, is less responsive to guitar volume attenuation than some vintage germanium fuzzes, the FZ-M retains a surprising amount of body and bite without sounding too thin. It can’t match the fuzzy-to-clean dynamic range of, say, a germanium Fuzz Face, but there are still many medium-gain and near-clean tones accessible via your guitar volume knob. The meatier “modern” mode adds midrange to the output that makes chord overtones clearer and tighter. It also adds more of the singing sonorities that increase sustain.
The FZ-M sounds pretty distinctive, which is not easy in a flooded fuzz sphere. Players that value sustain above all things may find the FZ-M lacking compared to something like a Big Muff. But the FZ-M is rich with character, loud, and equally capable of buzzy garage-psych lines and articulate chords, depending on where you set the classic/modern switch. That combination of capabilities is no mean feat, and the FZ-M does it all at a very nice price.
Comet Chorus
For more information about the Maestro pedal line, go to maestroelectronics.com.
Most good chorus pedals can generate a reasonable facsimile of a rotary speaker sound. The Comet Chorus, however, makes deep, rotary-like modulations the foundation of its voice. While you can generate ’70s- and ’80s-style chorus textures, there aren’t a wealth of tones here that match the liquid shimmer you associate with Roland, Boss, Ibanez, or EHX analog chorus from that era. Where the signature sounds of those units are distinguished, in part, by high harmonics that suggest ringing octave and unison strings from a 12-string, the Comet’s modulations have less sheen and excitability in the high frequencies—producing darker, pulsing, and arguably more mysterious chorus tones that evoke a Leslie or Fender Vibratone.
These modulations are an exciting alternative to canonical ’70s and ’80s chorus tones. But a lot of the Comet’s magic is its capacity to mix rotary-style sounds and vintage bucket brigade chorus to relatively unique ends. The Comet’s versatility even extends to generating cool vibrato tones at high mix and depth levels. And while I couldn’t match the queasiest, most intense textures of a dedicated vibrato unit, like a Boss VB-2, the Comet can sound like a cross between a dark vibrato and a Vibratone rotary speaker—a composite that, like actual rotary/chorus blends, can be mesmerizing.
One interesting facet of the Comet’s voice is the way that it thickens your tone and seems to add volume as you advance the mix. This can mean less defined modulations if you situate a gain source upstream. But the syrupy-thick modulations that result can sound awesome in a spare mix.
The Comet’s coolest feature might be its “orbit” mode, which adds tremolo to the already rich modulations. At modest depth and mix settings, the tremolo lends subtle complexity to the modulation waves. But at higher settings there’s more than a hint of an old Magnatone or Fender brown-panel amp’s throbby pitch wobble—sounds that lend greasy attitude to simple chord arpeggios and sass to soulful chord melodies and leads.
The Comet Chorus is a really lovely modulator—largely because it’s able to occupy unusual spaces that mix and bridge vibrato, chorus, and rotary speaker tones. Users hell-bent on nailing vintage-’80s chorus tones down to the letter may come away disappointed. For everyone else, there are a wealth of cool, even unusual modulation tones to mess with.
Invader Distortion
For more information about the Maestro pedal line, go to maestroelectronics.com.
While arguments over overdrives and fuzz inspire no end of vitriol among guitarists, distortion pedals—in strange inverse proportion to their aggressiveness—don’t seem to ignite the same feistiness amongst their proponents. Maybe that’s because almost any half-decent distortion pedal has the potential to transform the simplest riff into a Sunset Strip smash and unleash your inner animal. And if you’re in the right mood, they’re all pretty fun! The Maestro Invader excels at delivering such thrills. But it also offers a spacious voice that leaves lots of room for detail and quick-picking nuance. It’s no less rowdy than any of the classic distortions, but it tends to color your guitar’s sound much less and, in some cases, lets your amp breathe a lot more.
I don’t own a raft of distortion pedals, but I was able to run the Invader alongside a few classics. Compared to an ancient RAT2, the Invader was much brighter and sounded a lot less compressed. Alongside a Boss DS-1, it sounded airier, fuller, and less raspy. A battered MXR Distortion+ was perhaps the closet match, but still didn’t sound quite as open or detailed as the Invader. Part of the perceived (and very relative) clarity in the Invader is down to its inherent brightness and presence, which it mostly achieves without sounding shrill. There’s also the copious headroom. The Invader is loud—it’s little wonder why Maestro included a noise gate switch—so you can be very surgical and selective about how much distortion and bite you want to add on top.
The merits of these attributes are subjective, of course. I love the woof, compression, and darker capabilities of the RAT2, for instance. And even at its bassiest settings the Invader can’t deliver that pedal’s mysterious, cloudy sense of mass. For some players, though, the Invader will represent an ideal counterpoint to those hazier distortion tones. If you crave note articulation, massive volume, and the capacity to rise above a thick mix, the Invader is a distinctive sounding distortion alternative.
Discoverer Delay
For more information about the Maestro pedal line, go to maestroelectronics.com.
Bucket brigade delay, like copious heaps of butter, tends to make everything more delicious. So it goes with the Discoverer Delay. Fundamentally, there isn’t a ton of difference between the voice of the Discoverer and other affordable bucket brigade delays like the MXR Carbon Copy and the Ibanez Analog Delay Mini. Like those pedals, it tops out at about 600 milliseconds of delay, and a bit of clock noise is almost always present in the repeats. The Discoverer’s repeats, however, are ever-so-slightly darker and hazier than the echoes from those units. The Discover also colors the attack of an initial note in a similar way. Depending on your tastes and objectives, these are not bad, and among the attributes that draw players to bucket brigade delay in the first place.
What really distinguishes the Discoverer is its modulation. Not coincidentally, perhaps, the modulation in the Discoverer has a bit in common with the vibrato sounds in the Comet Chorus. As a result, the Discoverer’s basic architecture and functionality starts to look and sound a lot like an old EHX Deluxe Memory Man. But there are subtle differences between the modulation in the two. The DMM’s vibrato modulations, at least on my vintage unit, have a very trebly and squiggly quality. The Discoverer’s, by contrast, are throatier, smoother, and more present in the low-midrange, as well as a tiny bit faster, giving the Discoverer’s modulations a more rotary-speaker-like voice. The results are intoxicating and addictive, to say the least.
Old-school Deluxe Memory Man users that creatively utilize the scale and spacing of the original DMM’s controls for oscillation and pitch-shift effects will also be thrilled with how the Explorer’s layout facilitates many of the same moves. All three knobs can be adjusted simultaneously with an easy three-finger grip, and the knobs turn with a smooth resistance that makes fluid, improvisational moves a piece of cake.
Ranger Overdrive
For more information about the Maestro pedal line, go to maestroelectronics.com.
Carving out unique sounds isn’t easy in the overdrive realm. Even among very different overdrive pedals, you’ll often find a loss of audible crossover in tonality—particularly when you add additional pedals to the mix. And because Maestro has thus far been pretty secretive about what goes on under the hood, it’s hard to say which overdrive circuit, if any, inspired this design. To my ear, however, the basic voice aligns closely in both sound and feel with that of the Klon Centaur and better Klon clones. Maestro highlights the Ranger’s blend of clean and distorted tones as a feature. This is, of course, a hallmark of Klon design, which blends an op-amp distorted signal path with second and third paths of undistorted lows and boosted near-clean sounds, then blends the dirty and clean paths via the gain knob.
Like a Klon, there is a basic high-fidelity feel to the Ranger. And compared to a vintage TS9 or a Boss SD-1, the Ranger is discernibly more oxygenated and open-sounding in many of the same ways that distinguish a Klon from those pedals. There are still obvious differences in the performance envelope of the Ranger and the Klon-type pedals I used for comparison. The EHX Soul Food and Tone Bakery Creme Brulee I used as Klon stand-ins (the latter was a near dead-ringer for the real thing in a shootout) both have more available treble than the Ranger. But this could be a good thing if you’re trying to tame spiky transients in your overdriven signal without sounding overly compressed. And, in general, the Ranger’s not-too-bright voice makes it a great partner for stacking with fuzz and other overdrives, and tends to color your amp and guitar voice a lot less.

Milkman’s Jerry Garcia-style JG-40 combo.
Grateful Dead-inspired gear from Milkman and Scarlet Fire helps to keep the guitarist’s sound alive.
Guitar players wanting to catch the Grateful Dead’s particular lightning in a bottle exist along a spectrum. Some are content to take inspiration from Jerry Garcia’s playing but make their own way regarding guitar choice and signal path. Others strive to emulate Garcia’s sonic decisions down to the most minor details and create signal paths as close to Jerry’s as possible. In recent years, an ecosystem of gear has developed around fostering Jerry Garcia’s electric tone, including everything from guitars, amps, and stompboxes to on-board preamps and speakers.
Entire books about the Grateful Dead’s gear have been written, so we can’t cover it all here. Garcia tinkered with all facets of his sound from about 1971 until 1978, when his signal path reached stability. By then, his On-Board Effects Loop—an innovation he developed to control how much signal reached his effects—was dialed in, his backline firm, and his choice of effects pedals solidified. Even then, adjustments were made, especially when MIDI arrived or when technology like in-ear monitoring was used. Here are some basics.
Scarlet Fire’s recreation of Garcia’s Wolf, originally built by Doug Irwin.
It starts with guitars. For players wanting to get their Jerry on, there’s a wide range of Garcia-esque instruments—with just as wide a range of prices—out there. Recreations of the Doug Irwin guitars and the Fender Alligator Strat abound. China-built models from companies likePhred Instruments can go for as little as $700 or so. Luthier Thomas Lieber apprenticed with Irwin long ago, and his Lieber Guitars will deliver a copy of a variety of Garcia models. Leo Elliott’sScarlet Fire Guitars out of Dallas, Texas, takes things in another direction. Elliott builds Doug Irwin replicas that start at $20,000 and go up from there, with a current wait time of about 18 months for an instrument. He’s outfitted many of the top Garcia guitarists today, including Tom Hamilton Jr. and Jeff Mattson. Elliott says, “I’m a self-taught luthier; I didn’t really build my first guitar until 2010. I understood a little bit about woodworking before I got started, but I learned by reading books and through trial and error. I started building replicas of Doug Irwin’s Wolf guitar right away, which is sort of like building a car and starting with a Ferrari. I didn’t know any better. Then, eventually I got to know Doug Irwin and collaborated with him. So, I got to hold Garcia’s Tiger guitar and get to know it really well, and by 2015, I had built replicas of that guitar. There’s one guy who helps me around the shop, but otherwise, I am building these guitars on my own. I’m collaborating with Doug Irwin on a new series of Tiger guitars, which will retail for 50 grand each.” That’s one way to get your Jerry going.
The JBL-inspired Milkman K-120.
Garcia’s choice of amplifiers is another matter. He preferred Fender Twin Reverbs loaded with JBL Alnico speakers, which were popular amongst many rock bands in the 1970s. The details get complicated; Garcia’s amps were heavily modified, and the Fender Twin served as a preamp that ran to a McIntosh MC-3500 power amp.
It’s hard to find vintage JBL speakers today—at least ones in good shape. San Francisco’s Milkman Sound, founded by Tim Marcus, has created a faithful reproduction of those classic JBLsthey call the K-120. They’re coupling those speakers with a Garcia-style recreation of his Fender Twin that Marcus named the JG-40. “I think 75 percent of Jerry’s tone is in the JBL speakers,” Milkman’s founder says. “But when you start to analyze the other 25 percent, you kind of have to start withDon Rich. [Editor’s Note: Rich was the guitar player in Buck Owens’ band, pioneers of the Bakersfield Sound.] That’s Jerry’s tone, too, but the difference is Garcia’s midrange was a bit throatier. It sounds clean, but really, it’s not clean at the same time. Especially his tone in the late ’70s. There is something about running that Fender Twin Reverb through the McIntosh that would just completely blow out the tone in a really interesting way.”
Garcia colored his tone with off-the-shelf effects. This was, after all, long before the days of boutique pedals. By 1978 and beyond, you’d hear him playing through an MXR Distortion+, an MXR Analog Delay, and an MXR Phase 100. He often used auto wahs, preferring the Musitronics Mu-Tron envelope filter as well as a Mu-Tron Octave Divider and a Mu-Tron combination volume and wah pedal.
When I asked Jeff Mattson, Bella Rayne, and Tom Hamilton Jr. exactly how orthodox they are about using the kind of gear that Garcia did, I got three different answers.
Mattson tells me that because Dark Star Orchestra is doing something very specific, he really has to tailor his sound as carefully to Garcia’s as he can. “Some folks get too hung up on small things, like what kind of cable to use and things like that, and I don’t go that far. But it’s important for Dark Star Orchestra to get Jerry’s sound right because we are covering different eras and different shows. In 2022, for example, we went to Europe and recreated shows from the Dead’s famous Europe ’72 tour, so you have to pay close attention to what kind of gear they were using to do that right.”
Hamilton works differently. He’s always preferred a higher-gain signal than Garcia ever did, landing in more of a British or heavy metal tone. (Randy Rhoads was a big influence.) “I’ve always approached it like, ‘What’s the new information we can put into this thing?’” he says. “Not just recreate but pushing in a forward direction. And anytime I’ve played with the guys who played with Garcia back in the day, they always said to me, ‘You’re here because you’re here. Don’t try and do what we did back in 1978 or do it because Garcia did it that way.’ They’ve always encouraged me to be myself.”
Bella Rayne is just wrapping her head around what it really means to try to sound like Garcia. “Besides Jerry, I’m influenced by guitarists like Dickey Betts and Derek Trucks, so my tone tends to be a bit heavier and bluesy,” she explains. “I’m generally running a Stratocaster through a Fender Twin Reverb. But recently, I was doing a show, and a buddy of mine set up a Jerry rig for me, and that was so cool: JBL speakers, McIntosh head, the whole setup. I had never played through one. I didn’t know what the hype was all about. I plugged in, and it was just amazing; there was such a snap, and I was really commanding the band. I can see myself keeping my current rig but adding a Dead-rig to experiment. But honestly, anything is fine; I am not picky. I just want to play the best that I can.”
Brent Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing.
Professional transcriber Levi Clay has done the deepest of dives into Brent Mason’s hotshot licks. At one point, he undertook the massive project of transcribing and sharing one of Mason’s solos every day for 85 or so days. Mason is, of course, on of the most recorded guitarists in history, who helped define the sound of most ’90s country superstars. So, whether you know it or not, you’ve likely heard Mason’s playing. Levi shares the insight he gleaned from digging deep, and he tells us what it was like when they shared a stage last year. Plus, Levi plays us some great examples of Mason’s playing.
PRS Guitars today launched five new three-pickup, 22-fret models across the S2 and SE series. The S2 Series release includes the S2 Special Semi-Hollow and S2 Studio, while the SE Series welcomes the SE Special Semi-Hollow, SE Studio, and SE Studio Standard.
“The distinctive pickup configurations of these five guitars deliver a versatile tonal platform, whether you’re exploring subtle textures or pushing the envelope. The deep dive into our Narrowfield technology is obvious with this launch. With both the S2 models made in our Maryland factory and the SE models made in Indonesia, our goal has been to create guitars that will inspire you and spark creativity, all at an exceptional value,” said PRS Guitars COO, Jack Higginbotham.
S2 Special Semi-Hollow
The PRS S2 Special Semi-Hollow features a pair of 58/15 LT humbuckers in the bass and treble positions and a PRS Narrowfield in the middle. A 5-way blade switch and two mini-toggles allow players to tap the humbuckers, creating twelve distinct pickup combinations for sonic exploration. The carved maple top and mahogany back encompass a semi-hollow body that adds a natural airiness and depth to the guitar’s tone while enhancing sustain.
S2 Studio
The PRS S2 Studio delivers a wide range of sonic possibilities through its distinctive single-single-hum configuration. Featuring two proprietary PRS Narrowfield pickups in the bass and middle positions and a 58/15 LT humbucker in the treble position, the S2 Studio offers a palette of sounds from single-coil clarity to vocal humbucker tones. This model also has a 5-way blade switch and push/pull tone control.
SE Special Semi-Hollow
The PRS SE Special Semi-Hollow is designed with the versatility of a hum/“single”/hum setup, bringing PRS’s Narrowfield DD pickup design to the SE Series in a classic maple-top guitar. The semi-hollow construction also enhances sustain and resonance, while the f-hole adds a classic aesthetic. The coil-tap switching system unlocks a wide range of tones through a pair of 58/15 LT “S” pickups in the bass and treble positions and a PRS Narrowfield DD “S” in the middle.
SE Studio
The PRS SE Studio’s “single”/”single”/hum pickup configuration provides a wide range of tonal options. This combination of PRS Narrowfield DD “S” bass and middle pickups with a PRS 58/15 LT “S” treble humbucker offers humbucking warmth, single-coil sparkle, and everything in between. The 5-way blade switch and push/pull tone control further enhance its versatility.
SE Studio Standard
The only bolt-on neck in this release group, the PRS SE Studio Standard brings the tone, playability, and versatility of the Studio model to the SE Series and into an all-mahogany design with a vintage-style pickguard aesthetic. At the heart of the SE Studio Standard is its versatile trio of pickups: an 58/15 LT “S” humbucker in the treble position with two Narrowfield DD “S” pickups in the middle and bass positions. The 5-way blade switch and push/pull tone control allow for an array of pickup configurations.
