On their new album, Judas Priest brandish an Invincible Shield of righteous heavy metal.
When people talk about Judas Priest, the band’s biggest hits easily spring to mind, and rightfully so. “Breaking the Law,” “Living After Midnight,” “Heading Out to the Highway,” and “You’ve Got Another Thing Comin’” were the songs that made the iconic British metal band a household name in the ’80s. But long before such MTV-friendly anthems catapulted them into superstardom, and more recently, earned them a nod from the Rock and Roll Hall of Fame in the Musical Excellence category, Judas Priest cut a more progressive rug.
Their ’70s-era albums, like Stained Class and Sin After Sin (the latter featuring session drummer extraordinaire Simon Phillips), are masterworks of early progressive metal. Songs like “Victim of Changes,” “Sinner,” and “Beyond the Realms of Death” exude a stylistic depth and structural breadth that was mostly shed during their ’80s heyday. The rhythms—bass and drums in particular—were more adventurous, and the arrangements more intricate. It’s a style of music that would subsequently evolve through bands like Iron Maiden, Dream Theater, and others who have since come to define and expand the genre.
On their new album Invincible Shield, Judas Priest is retrieving a bit of that musical heritage. “I said a long time ago, when we were writing these songs, that they came out a bit more progressive,” says lead guitarist Richie Faulkner. “It’s not progressive like Dream Theater or Rush, but there are a few more twists and turns musically.” Indeed, the songs on Invincible Shield are definitely more complex than one might expect from the band, with many of the arrangements more akin to their ’70s period than the following decade’s crowd-pleasers. Songs like “Panic Attack” and “Trial By Fire” are either built around, or feature significantly, odd-time riffs, a far cry from the 4/4 time signatures Judas Priest built their global success around. Throw in a heaping cup of Screaming for Vengeance-era ferocity in terms of delivery on songs like “Gates of Hell” and “Crown of Horns,” and you have the basic ingredients of Invincible Shield. Bass player Ian Hill, who has been going through the set list for the upcoming tour, is also connecting the musical dots to past works. “The things I’m running through, like ‘Victim of Changes,’ ‘Sinner,’ and ‘The Sentinel,’ are all in the same mold,” the bassist explains. “There are lots of different parts—light and shade—it’s not just all one thing or another. And Invincible Shield is very much like that.”
Judas Priest - Crown of Horns
Originally formed in Birmingham, England, in 1969, Judas Priest has been through an unusually long list of lineup changes, with the core of the band evolving to include guitarists K.K. Downing and Glenn Tipton, bassist Ian Hill, and singer Rob Halford by the release of their debut LP, Rocka Rolla, in 1974. A revolving cast of drummers, including Les Binks and the aforementioned Phillips, mostly ended when Dave Holland joined in 1979, occupying the position for 10 years. Following his departure, Scott Travis joined and has been with the band ever since. Downing left the band in 2011, replaced by Faulkner. Tipton remains an official member of Judas Priest, but his touring activities have been limited since 2018 due to Parkinson’s disease, with Firepower and Invincible Shield producer Andy Sneap filling in for him on the road.
“There are lots of different parts—light and shade—it’s not just all one thing or another.” —Ian Hill
The elements of early Judas Priest’s sound, including Halford’s operatic vocal style and the twin-guitar power of Downing and Tipton, forged a template that would help define the heavy metal genre. Their 1977 release Sin After Sin was their first under a major label, and the first of 10 consecutive records to be certified Gold or Platinum. Then, 1980’s British Steel brought them notable mainstream attention with hits “Breaking the Law” and “Living After Midnight.” A decline in exposure during the mid 1990s, coinciding with Halford leaving and being replaced by Tim “Ripper” Owens, seems a distant memory, as the 2000s saw the band once again become a major force within the metal community. They were inaugural inductees into the VH1 Rock Honors in 2006, received a Grammy Award for Best Metal Performance in 2010, and had their songs featured in popular video games such as Guitar Hero and Rock Band. 2018’s Firepower was the highest-charting album of the band’s career, and in 2022, Judas Priest were finally inducted into the Rock and Roll Hall of Fame.
Judas Priest caused quite a stir online when they announced the title and artwork for their 19th studio record, but Richie Faulkner says it’ll all make sense in the end.
Priest’s musical renaissance on Invincible Shield certainly adds greater dimension to their signature sound, but it isn’t really about taking a trip down memory lane. The nod to the past is mostly tangential. The real impetus was wanting to scratch a particular collective itch. “It’s a question of, ‘What can we do different? How can we make this more satisfying as a piece of art?’ If that doesn’t sound too pompous,” explains Faulkner. “You want to challenge yourself and you want to build upon what you’ve done already.”
“It’s a question of, ‘What can we do different? How can we make this more satisfying as a piece of art?’” —Richie Faulkner
Priest has never really been a band to repeat themselves too often. Yes, they’ve followed trends and exhausted songwriting formulas, but they’ve always adapted to changing times and band members. Between Andy Sneap’s fiery, modern production, Faulkner’s youthful and aggressive influence, and the underlying DNA—four of the guys in the band have been there for decades—Judas Priest pull off a pretty compelling hat trick on Invincible Shield. “You want to do something that’s going to be challenging, but also satisfying to us as creative people, and hopefully ticks the boxes for the fans as well,” says Faulkner.
There was, however, a bit of backlash from fans on social media over the album’s title and artwork when it was first announced—commenters felt it was boring and “cheesy”—but Faulkner says context will hopefully bring it all together. “I saw the comments,” he says. “I don’t stick my head in the sand. It’s heavy metal, it’s the shield that we all fly proudly and get behind, and it’s the thing that binds us together.” When the name, the artwork, and ultimately the music all come together, it will make sense, he says.

With Tipton sidelined and Downing out of the fold for more than a decade now, much of the writing and recording on Invincible Shield fell on Faulkner’s shoulders. Tipton is still contributing from the bench, but it’s Faulkner’s show now. When asked about the musical direction on Invincible Shield, Tipton adds, “It is definitely a case of Richie joining the writing team with his own individual ideas and going at it from slightly different angles.”
“It’s a question of, ‘What can we do different? How can we make this more satisfying as a piece of art?’” —Richie Faulkner
One noticeable difference wrought by those writing angles is the standout performance on Invincible Shield from Ian Hill. Though he’s been historically overlooked in the annals of great metal bassists, Hill has been the foundation of Judas Priest from the beginning, and is, in fact, the band’s only full-time original member. On Invincible Shield, he proves to be more than a root-note-pumping low-ender. Songs like “Panic Attack,” “The Serpent and the King,” and “Giants in the Sky” feature what Hill would call “busy bass work.” There are a lot of unison riffs between the bass and guitars, more along the lines of what you might expect from Iron Maiden, for example, or Stained Class Priest, even. Yet Hill’s approach remains simply focused on the songs. “I’ve always not done much more than what’s necessary,” he explains. “If you’re putting too much on it, you’re actually detracting from the song. This time around, the songs are busier and called for a little more movement.”

Unlike Firepower, an album they had the luxury of recording together, Invincible Shield was done remotely, largely due to the pandemic. “The bare bones of these songs have been around since 2020, just before the lockdowns happened,” recalls Faulkner. After the lockdowns were lifted, the band went back out on the road for their 50th Anniversary tour, and scheduling conflicts ensued. Not to be deterred, and with enough experience to know there’s never a perfect time to do something, the band decided they were going to record the new album however they could, rather than wait for the perfect moment. “Sometimes you just have to do what you can do with the tools that you have,” says Faulkner. “So, I recorded the guitars in my studio at home. The drums were recorded in Nashville, and Rob’s vocals in Phoenix.” Hill actually put most of his bass lines down in hotel rooms on the last tour. “Andy is with us anyway, and he’s got his laptop,” Hill explains. “And you get these days off where you’re sitting around doing nothing, so we figured we might as well be productive. It was a great way to do it, just me and Andy. You’ve got another pair of eyes and you can try different things for the same part.”
“I’ve always not done much more than what’s necessary.” —Ian Hill
Invincible Shield is also a testament to how technology has revolutionized the process of making records, even for Rock and Roll Hall of Fame inductees. Faulkner tracked his guitars at home using the Neural DSP Quad Cortex on a Marshall plexi-like setting. He then sent Sneap that sound along with a clean DI, so he could reamp it. “I think it was a Marshall JCM800 that he used. It’s a new combination—I’m joking,” he laughs, citing the holy grail of rock guitar amps. Faulkner says Sneap also put some gain boost in the front. “He’s a fan of the EVH 5150III and he had some plexis that he was using as well, so I’m not sure how he blended them, but that’s what he usually uses.”
Ian Hill's Gear
This year mark’s Judas Priest’s 55th year as a band, but they’re still chasing artistic and musical goals. “There’s always a challenge in making art,” says Faulkner, “and that’s what makes it special.”

Tipton says the rhythm guitars are put down to create a certain sound throughout the album, but for lead breaks, they will try anything to create the sound they want. “I’ll tweak [my sound] with different mikes and effects,” he explains. “Andy is very good with shaping the guitar sounds, and he knows what he needs to do to get it to sound like Priest.” The bass runs clean, direct to a laptop via an interface. Hill says this has been his approach for some time. “You need a clean bass sound—one that cuts through the two distorted guitars,” he says. “Anything that needs to be changed, or any effect that needs to go on, is put on afterwards.”
As for the actual songwriting process, Tipton says it remains more or less the same, whereby he, Halford, and Faulkner all produce ideas separately then pool them together. But Faulkner has a slightly more nuanced take on the songwriting process, one that you might expect from someone who grew up a fan of the band.
“It’s heavy metal, it’s the shield that we all fly proudly and get behind, and it’s the thing that binds us together.” —Richie Faulkner
“It’s the scariest thing,” he admits. “Let’s say you take fifteen ideas, they’re not complete—they’re just ideas that you think are winners. Then, it’s your turn to put your stuff on and show the room. You think it’s good, but then you put it on in front of Glenn Tipton and Rob Halford, you’re thinking, ‘Oh my god, what have I done here?’ Because all of a sudden, all your stuff sounds like shit,” he laughs. “I think that’s just the insecurities, and then you realize, they put ideas forward and they’re thinking the same thing.” One of the things Faulkner appreciates about this process is that it challenges him to think differently about his own ideas. “Glenn might say, ‘Turn that bit around,’ or ‘Change the feel in that bit.’ And then I do it and it’s like, ‘Ah, that’s actually unique. I wouldn’t have thought of that.’ And that’s when having three creative minds in the room makes the end result a lot better.”
When it comes to crafting and tracking his guitar solos, Faulkner says about 75 percent of it is improvised. “We press record and let it rip,” he explains. “You do that three or four times and a couple of things become constant, subconsciously, and they stick, and so you build around that.” There are a few songs he worked out before recording, including “Panic Attack,” “Invincible Shield,” and “As God Is My Witness.”
“It’s your turn to put your stuff on and show the room. You think it’s good, but then you put it on in front of Glenn Tipton and Rob Halford, you’re thinking, ‘Oh my god, what have I done here?’” —Richie Faulkner
Circling back around to the way Invincible Shield was pieced together remotely, Faulkner says there are always challenges when you record music. “Whether it’s Jaws and the shark is not working, or it’s our situation, there’s always a challenge in making art and that’s what makes it special,” he says. “The challenge for us was getting Invincible Shield to sound cohesive while recording it separately. By overcoming those challenges, it arms you for the next one, and you do it again and hopefully grow.”

Wampler Mofetta
wamplerpedals.com
Wampler’s new Mofetta is a riff on Ibanez’s MT10 Mostortion, a long-ago discontinued pedal that’s now an in-demand cult classic. If you look at online listings for the MT10, you’ll see that asking prices have climbed up to $1k in extreme cases.
It would have been easy for Wampler to simply make a Mostortion clone and call it a day, but they added some unique twists to the Mofetta pedal. While the original Mostortion had a MOSFET-based op amp, it actually used clipping diodes to create its overdrive. The Mofetta is a fairly accurate replica and includes that circuitry, but also has a toggle switch for texture, which lets you choose between the original-style diode-based clipping in the down position and multi-cascaded MOSFET gain stages in the up position.
Luscious Low Gain and Meaty Mid-Gain
The Mofetta’s control panel is very straightforward and conventional with knobs for bass, mids, treble, level, and gain. The original Mostortion was revered for its low-gain tone and is now popular among Nashville session guitarists. Wampler’s tribute captures that edge-of-breakup vibe perfectly. I enjoyed using the pedal with the gain on the lower side, around 9 o’clock, where I heard and felt slight compression that gave single notes a smooth and silky feel. I particularly enjoyed the tone-thickening the Mofetta lent to my Ernie Ball Music Man Axis Sport’s split-coil sound as I played pop melodies and rootsy, triadic rhythm guitar figures. The Mofetta has expansive headroom, and as a result there’s a lot of space in which you can find really bold, cutting tones without muddying the waters too much. Even turning the gain all the way off yields a pleasing volume bump that would work well in a clean boost setting.
There’s a lot of space in which you can find really bold, cutting tones without muddying the waters too much.
Switching the texture switch up engages the MOSFET section, introducing cascading gain stages that elevate the heat and add flavor the original Mostortion didn’t really offer. Classic rock and early metal are readily available via the MOSFET setting. If you need to stretch out to modern metal sounds, the Mofetta probably isn’t the pedal for you. Again, the original Mostortion was, first and foremost, a low-to-mid-gain affair, so unless you’re using it as a boost with a high-gain amp, the Mofetta is not really a vehicle for extreme sounds.
One of the Mofetta’s real treats is its responsiveness. Even at higher gain settings the Mofetta is very touch sensitive. You can tap into a wide range of dynamic shading just by varying the strength of your pick attack. I enjoyed playing fast, ascending scalar passages, picking with a medium attack then really slamming it hard when I hit a high climactic note, to get the guitar to really scream.
The Verdict
Wampler is a reliably great builder who creates pedals with a purpose. I own two of his pedals, the Dual Fusion and the Pinnacle, and both are really exceptional units. The Mofetta captures the essence of the Mostortion and makes it available at an accessible price. But even if you’ve never heard or played an original Mostortion, you’ll appreciate the truly versatile EQ, touch sensitivity, and the bonus texture switch, which expands the Mofetta’s range into more aggressive spaces. The wealth of dirt boxes on the market today can make a player jaded. But Wampler pushed into a relatively unique, satisfying, and interesting place with the Mofetta.
Although inspired by the classic Fuzz Face, this stomp brings more to the hair-growth game with wide-ranging bias and low-cut controls.
One-ups the Fuzz Face in tonal versatility and pure, sustained filth, with the ability to preserve most of the natural sonic thumbprint of your guitar or take your tone to lower, delightfully nasty places.
Pushing the bias hard can create compromising note decay. Difficult to control at extreme settings.

Catalinbread StarCrash
catalinbread.com
Filthy, saturated fuzz is a glorious thing, whether it’s the writ-large solos of Big Brother and the Holding Company’s live “Ball and Chain,” the soaring feedback and pure crush of Jimi Hendrix’s “Foxy Lady,” or the sandblasted rhythm textures of Queens of the Stone Age’s “Paper Machete.” It’s also a Wayback Machine. Step on a fuzz pedal and your tone is transported to the ’60s or early ’70s, which, when it comes to classic guitar sounds, is not a bad place to be.
Catalinbread’s StarCrash is from their new ’70s collection, so the company is laying its Six Million Dollar Man trading cards on the table—upping the ante on traditional fuzz with more controls and, according to the company’s website, a little more volume than the average fuzz pedal, while still staying in the traditional Fuzz Face lane.
The Howler’s Viscera
Arbiter Electronics made the first Fuzz Face in 1966. The StarCrash is inspired by that 2-transistor pedal, but benefits from evolution, as did almost all fuzz pedals in the ’70s, when the standard shifted from germanium to silicon circuitry to improve the consistency of the effect’s performance. The downside is that germanium is gnarlier to some ears, and silicon transistors don’t respond as well to adjustments made via a guitar’s volume control.
While Fuzz Faces have only two knobs, volume and fuzz, the silicon StarCrash has three: volume, bias, and low-cut. Catalinbread’s website explains: “We got rid of that goofy fuzz knob. We know that 95 percent of all players run it dimed, and the remaining 5 percent use their guitar’s volume knob to rein it in.”
I suspect there are plenty of players who, like me, do adjust the fuzz control on their pedals, but the most important thing is that the core fuzz sound here is excellent—bristly and snarling, with a far girthier tone than my reissue Fuzz Face. It’s also, with the bias and low-cut controls, far more flexible. The low-cut control allows you to range from a traditional, comparatively thinner Fuzz Face sound (past noon and further) to the StarCrash’s authentic, beefier voice (noon and lower). Essentially, it cuts bass frequencies from 40 Hz to 500 Hz, resulting in an aural menu that runs from lush and lowdown to buzzy and slicing. And the bias control is a direct route to the spitty, fragmented, so-called Velcro-sound that’s become a staple of the stoner-rock/Jack White school of tone. The company calls this dial a “dying battery simulator,” and it starves the second transistor to achieve that effect.
Sweet Song of the Tribbles
Playing with the StarCrash is a lot of fun. I ran it through a pair of Carr amps in stereo, adding some delay and reverb to mood, and used a variety of single-coil- and humbucker-outfitted guitars. While both pickup types interacted well with the pedal, the humbuckers were most pleasing to my ears with the bias cranked to about 2 o’clock or higher, since the ’buckers higher output allowed me to let notes sustain longer before sputtering out. Keeping the low-cut filter at 9 o’clock or lower also helped sustain and depth in the Velcro-fuzz zone, while letting more of the instruments’ natural voices come through, of course.
With the low-cut filter turned up full and the bias at 10 o’clock, I got the StarCrash to be the perfect doppelganger of my Hendrix reissue Fuzz Face. But that’s such a small part of the pedal’s overall tone profile. It was more fun to roll off just a bit of bass and set the bias knob to about 2 or 3 o’clock. Around these settings, the sound is huge and grinding, and yet barre chords hold their character while playing rhythm, and single-note runs, especially on the low strings, are a filthy delight, with just the right schmear of buttery sustain plus a hint of decay lurking behind every note. It’s such a ripe tone—the sonic equivalent of a delicious, stinky cheese—that I could hang with it all day.
Regarding Catalinbread’s claims about the volume control? Yes, it gets very loud without losing the essence of the notes or chords you’re playing, or the character of the fuzz, which is a distinct advantage when you’re in a band and need to stand out. And it’s a tad louder than my Fuzz Face but doesn’t really bark up to the level of most Tone Bender or Buzzaround clones I’ve heard. In my experience, these germanium-chipped critters of similar vintage can practically slam you through the wall when their volume levels are cranked.
The Verdict
Catalinbread’s StarCrash—with its sturdy enclosure, smooth on/off switch and easy-to-manipulate dials—can compete with any Fuzz Face variant in both price and performance, scoring high points on the latter count. The bias and low-cut dials provide access to a wider-than-usual variety of fuzz tones, and are especially delightful for long, playful solos dappled with gristle, flutter, and sustain. Kudos to Catalinbread for making this pedal not just a reflection of the past, but an improvement on it.

Red Panda Radius
redpandalab.com
The release of a newRed Panda pedal is something to be celebrated. Each of the company’s devices lets us crack into our signal chains and tweak its inner properties in unique, forward-thinking ways, encouraging us to be daring, create something new, and think about sound differently. In essence, they take us to the sonic frontier, where the most intrepid among us seek thrills.
Last January, I got my first glimpse of the Radius at NAMM and knew that Red Panda mastermind Curt Malouin had, once again, concocted something fresh. The pedal offers ring modulation and frequency shifting with pitch tracking and an LFO, and I heard classic ring-mod tones as the jumping off point for oodles of bold sounds generated by envelope and waveform-controlled modulation and interaction. I had to get my hands on one.
Enjoy the Process
I’ve heard some musicians talk about how the functionality of Red Panda’s pedals are deep to a point that they can be hard to follow. If that’s the case, it’s by design, simply because each Red Panda device opens access to an untrodden path. As such, it can feel heady to get into the details of the Radius, which blends between ring modulation and frequency shifting, offering control of the balance and shift ratios of the upper and lower sidebands to create effects including phasing, tremolo, and far less-natural sounds.
As complex as that all might seem, Red Panda’s pedals always make it easy to strip the controls down to their most essential form. The firmest ground for a guitarist to stand with the Radius is a simple ring-mod sound. To get that, I selected the ring mod function, turned off the modulation section by zeroing the rate and amount knobs, kept the shift switch off and the range switch on its lowest setting. With the mix at noon and the frequency knob cranked, I found my sound.
From there, by lowering the frequency range, the Radius will yield percussive tremolo tones, and the track knob helped me dial that in before opening up a host of phaser sounds below noon. By going the other direction and kicking the rate switch into its higher setting, a world of ring-mod tweaking opens up. There are some uniquely warped effects in these higher settings that include dial-up modem sounds and lo-fi dial tones. Exploring the ring mod/frequency shift knob widens the possibilities further to high-pitched, filtered white noise and glitchy digital artifacts at its extremes.
There are wild, active sounds within each knob movement on the Radius, and the modulation section naturally brings those to life in more ways than a simple knob tweak ever could, delivering four LFO waveforms, a step modulator, two x-mod waveforms, and an envelope follower. It’s within these settings that I found rayguns, sirens, Shepard tones, and futuristic sounds that were even harder to describe.
It’s easy to imagine the Radius at the forefront of sonic experiments, where it would be right at home. But this pedal could easily be a studio device when applied in low doses to give a track something special that pops. The possible applications go way beyond guitars.
The Verdict
The Radius isn’t easy to plug and play, but it’s also not hard to use if you keep an open mind. That’s necessary, too: The Radius is not for guitar players who prefer to stay grounded; this pedal is for sonic-stargazers and producers.
I enjoyed pairing the Radius with various guitar instruments—12-string, baritone, bass—and it kept getting me more and more excited about sonic experimentation. That feeling is a big part of what’s special about this pedal. It’s so open-ended and controllable, continuing to reveal more of its capabilities with use. Once you feel like you’ve gotten something down, there are often more sounds to explore, whether that’s putting a new instrument or pedal next to it or exploring the Radius’ stereo, MIDI, or expression-pedal functionality. Like many great instruments, it only takes a few minutes to get started, but it could keep you exploring for years.
