Mark Tremonti’s relationship with PRS Guitars began in 2000 with his first signature guitar. Eight years later, he had his first signature amp, theMT 15, a successful lunchbox amp that received a Best in Show award at the NAMM show that year. The new 100-watt, 3-channelMT 100 takes Tremonti’s tone concepts to higher and louder heights.
Three Corners of a Colossus
The MT 100 is designed by amp guru Doug Sewell, who built much-revered amps under his name before Paul Reed Smith recruited him. The tube layout includes four 6L6GC power amp tubes—typical enough for a 100-watt amp. But there are eight 12AX7 preamp tubes because each channel has its own preamp section. The clean channel uses one preamp tube (V1) and the overdrive and lead channels each use two. And while the MT 100’s many knobs suggest a complicated affair, the amp is actually pretty straightforward. Each channel has its own controls for presence, master, bass, middle, treble, and gain—that’s it. On the back panel is a tube-driven, series effects loop, where you can patch in reverb or delay as desired. There’s also a very handy panel of bias jacks. A 3-button footswitch is included and there are corresponding LED lights on the switch and the amp’s faceplate (blue for clean, orange for overdrive, and red for lead), so you know which channel is engaged.
Five Years in the Making
f you only know Mark Tremonti from Alter Bridge and Creed, you’d probably assume the MT 100 is a high-gain flamethrower. It’s much more than that, though. Tremonti is an amp fanatic, and his stage setup has traditionally been pretty complex, ranging from Dual Rectifiers for dirty sounds to Twin Reverbs for clean ones. The MT 100 impressively covers much of that turf via a single amplifier.Initially the MT 100 was going to have a 2-channel design like the MT 15, but Tremonti wanted to add an overdrive channel. When Iinterviewed Tremonti in 2012, he talked of his love of Dumbles. The MT 100’s middle channel is inspired by his favorite Dumble, and took five years of back and forth before the design was finalized. Dumble-style amps are typically extra expensive, so the MT 100’s $1,849 price feels like a bargain for an amp that does Dumble and then some.
With Ears Wide Open
I plugged a couple of guitars into an MT 100, including a semi-hollow and a dual-humbucker solid-body with split-coil options, with the amp hooked up to a Celestion-equipped cabinet. It was easy to find sweet spots for each instrument I tried. With the clean channel’s tone controls at noon and the presence a touch lower than that, the MT 100 sounds bright and a lot like a Fender Twin, with more warmth and copious bottom end. The clean channel brings small details to life. Fingerpicked open chords laced with hammer-on and pull-off embellishments, for example, sound especially pretty. And while the clean sounds are full-bodied, they leave a lot of space for effects like delay and reverb. I do wish that the MT 100 had built-in reverb. Almost all of us have loads of effects at the ready, but it’s also nice when an amp—and clean channel—this fundamentally good enables you to plug and play with a reverb option.
The overdrive channel is a delight, particularly when I use my semi-hollow. With the tone controls all around noon, the presence at 9 o’clock, and the gain at 2 o’clock, I could cop Robben Ford and Larry Carlton fusion sounds in a jiffy. But the overdrive channel isn’t just smooth and heavy. With a bridge-position humbucker and the gain control all the way up, it was easy to tap Brit-style metal and hard rock tones.
For Tremonti fans, the lead channel is probably the MT 100’s main attraction, and it definitely lives up to expectations. Lead sounds bloom with sustain, and notes would ring forever whether humbuckers or split-coils drove the front end. Palm-muted rhythm figures felt massive—floor-shakingly massive. And though you could fairly categorize the lead channel as dark and heavy at times, it’s far from muddy. You’ll hear a lot of detail in these zones. What’s also cool is that the tone foundation of the lead channel is distinctly different than that you hear on the overdrive channel. It really comes across as two different amps rather than the same basic sound with different gain variations on each of the two heavy channels. Factor in the use of effects and you’re looking at a lot of tone possibilities. Switching between channels, incidentally, is smooth, organic, and free from the jarring pops that some channel-switching amps exhibit.The Verdict
In a lot of ways, PRS was brave to build the MT 100. One hundred watts is a lot of power to wrangle, and to get the amp to really move air it needs to be cooking at a volume level that may not be practical in a lot of gigging situations. Obviously, an attenuation option might have been a nice touch (though you can argue that’s what the lunchbox-sized MT 15 is for), and if you use a load box/speaker simulator like UA’s OX, you can still get in on the fun. In larger environments that can handle it with a big cab, though, it is at its most beastly.
PRS and Tremonti should be commended for choosing a streamlined design path, too. Sure, it has three channels, but it forgoes power-scaling capabilities, graphic EQ, the option to use different types of power tubes, a foot-switchable effects loop, or direct recording/speaker cabinet cloning outputs like so many modern amps. And while it eschews bells and whistles, the MT 100 dominates in terms of tone—each of the MT 100’s three channels is dripping with it. If an amp that offers delicious Fender Twin Reverb-meets-Bruno Underground clean tones, a dead-on Dumble-sounding overdrive channel, and a hellacious lead channel that can stand head-to-toe with the Dual Rectifiers, Uberschalls, and 5150s of the world sounds cool to you, you’re probably not going to think once about the lack of gimmicks.

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.
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.

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.
