Boss streamlines the size, features, and price of the already excellent Waza Tube Expander with little sacrifice in functionality.
Many of our younger selves would struggle to understand the urge—indeed, the need—to play quieter. My first real confrontation with this ever-more-present reality arrived when Covid came to town. For many months, I could only sneak into my studio space late at night to jam or review anything loud. Ultimately, the thing that made it possible to create and do my job in my little apartment was a reactive load box (in this case, a Universal Audio OX). I set up a Bassman head next to my desk and, with the help of the OX, did the work of a gear editor as well as recorded several very cathartic heavy jams, with the Bassman up to 10, that left my neighbors none the wiser.
Boss’ firstWaza Tube Amp Expander, built with an integrated power amp that enables boosted signal as well as attenuated sounds, was and remains the OX’s main competition. Both products have copious merits but, at $1,299 (Boss) and $1,499 (Universal Audio), each is expensive. And while both units are relatively compact, they aren’t gear most folks casually toss in a backpack on the way out the door. The new Waza Tube Expander Core, however, just might be. And though it sacrifices some refinements for smaller size, its much-more accessible price and strong, streamlined fundamental capabilities make it a load-box alternative that could sway skeptics.
Micro Manager
The TAE Core is around 7 1/2" wide, just over 7 " long, and fewer than 4 " tall, including the rubber feet. That’s about half the width of an original TAE or OX. The practical upside of this size reduction is obvious and will probably compel a lot of players to use the unit in situations in which they’d leave a full-size TAE at home. The streamlined design is another source of comfort. With just five knobs on its face, the TAE Core has fewer controls and is easier to use than many stompboxes. In fact, the most complicated part of integrating the TAE Core to your rig might be downloading the necessary drivers and related apps.
Connectivity is straightforward, though there are some limitations. You can use TAE Core wirelessly with an iOS or Windows tablet or smartphone, as long as you have the BT-DUAL adaptor (which is not included and sets you back around 40 bucks). However, while desktop computers recognize the TAE Core as a Bluetooth-enabled device, you cannot use the unit wirelessly with those machines. Instead, you have to connect the TAE Core via USB. In a perfectly ordered world, that’s not a big problem. But if you use the TAE Core in a small studio—where one less cable is one less headache—or you prefer to interface with the TAE Core app on a desktop where you can toggle fast and easily between large, multi-track sessions and the app, the inability to work wirelessly on a desktop can be a distraction. The upside is that the TAE Core app itself is, functionally and visually, almost identical in mobile and desktop versions, enabling you to select and drag and drop virtual microphones into position, add delay, reverb, compression, and EQ effects, choose various cabinets with different speaker configurations and sizes, and introduce new rigs and impulse responses to a tone recipe in a flash. And though the TAE Core app lacks some of the photorealistic panache and configuration options in the OX app, the TAE Core’s app is just as intuitive.Less Is More
One nice thing about the TAE Core’s more approachable $699 price is that you don’t have to feel too bad on nights that you “underutilize” the unit and employ it as an attenuator alone. In this role, the TAE Core excels. Even significantly attenuated sounds retain the color and essence of the source tone. Like any attenuator-type device, you will sacrifice touch sensitivity and dynamics at a certain volume level, yielding a sense of disconnection between fingers, gut, guitar, and amp. But if you’re tracking “big” sounds in a small space, you can generate massive-sounding ones without interfacing with an amp modeler and flat-response monitors, which is a joy in my book. And again, there’s the TAE Core’s ability to “expand” as well as attenuate, which means you can use the TAE Core’s 30-watt onboard power amp to amplify the signal from, say, a 5-watt Fender Champion 600 with a 6" speaker, route it to a 2x12, 4x12, or virtual equivalent in the app, and leave your bandmate with the Twin Reverb and bad attitude utterly perplexed.
The Verdict
Opting for the simpler, thriftier TAE Core requires a few sacrifices. Power users that grew accustomed to the original TAE’s super-tunable “resonance-Z” and “presence-Z” controls, which aped signal-chain impedance relationships with sharp precision, will have to make do with the simpler but still very effective stack and combo options and the “air feel level” spatial ambience control.The DC power jack is less robust. It features only MIDI-in rather than MIDI-in/-through/-out jacks, and, significantly, 70 watts less power in the onboard power amp. But from my perspective, the Core is no less “professional” in terms of what it can achieve on a stage or in a studio of any size. Its more modest feature set and dimensions are, in my estimation, utility enhancements as much as limitations. If greater power and MIDI connectivity are essentials, then the extra 600 bones for the original TAE will be worth the price. For many of us, though, the mix of value, operational efficiencies, and the less-encumbered path to sound creation built into the TAE Core will represent a welcome sweet spot that makes dabbling in this very useful technology an appealing, practical proposition.

I love fuzz. I am so grateful for fuzz. I don’t know who or where I’d be—at least musically—without it. And whether or not you like using fuzz, you love fuzz, too. You just might not realize it. Fuzz pedals, which are considered loud, rowdy, and unnecessary musical devices by some tonal purists, have changed the world.
From Jimi Hendrix to Jack White, David Gilmour to Billy Corgan, fuzz pedals have not only shaped guitar sounds but shaped the way we think of and experience guitar. Starting in the 1960s, they have steered culture as the musical voice of protest (Hendrix’s “Machine Gun,” anyone?) and the communicator of a generation’s angst . And don’t forget the more recent doom and stoner genres! Also, some tones that you perceive as clean or merely overdriven are actually created by finding the sweet spot between a fuzz pedal and a guitar’s volume dial.
There are tons of different fuzz pedals out there right now, so navigating all of your options can seem like a difficult task. We truly live in the golden era of gear and, as a pedalhead, I’m here for it. But the roots of fuzz run deep to earlier eras. So in that spirit, here are some of my favorite modern fuzz boxes that nail the tones of yesteryear—without the vintage-market price tag. Enjoy! And keep thinking fuzzy!EarthQuaker Devices Hoof ($179 street)
The Hoof is a flagship pedal from this Akron, Ohio-based company, and for good reason. This pedal’s circuit is rooted in a specific tall-font Sovtek Big Muff owned by the Black Keys’ Dan Auerbach. According to Jamie Stillman, owner of EQD, Auerbach’s favorite Big Muff didn’t sound quite like other green Russian Big Muffs he’d played, so he approached Stillman to recreate its hairy goodness. The Hoof is a hybrid of germanium and silicon transistors—a modern variant of the Muff’s legendary, strictly silicon sound. While the original is a 3-knob fuzz (volume, tone, and distortion), the kicker here is a fourth “shift” control that allows you to dial in additional midrange to your liking. Want that doom-y wall of sound? It’s here. Need a bit more string articulation for your riffs? It can do that as well. Built tough, the Hoof is extremely easy to use to get killer vintage fuzz tones and will take a beating on the road.
Way Huge Swollen Pickle ($149 street)
Star designer Jeorge Tripps has had a huge impact in the pedal world for decades. The Swollen Pickle is one of the staples in his creative lineup. What started as a 3-dial Big Muff-style fuzz (See a pattern here?) took on a life of its own with the addition of “filter” and “scoop” controls. Between these two knobs, the sonic landscape is huge... you could even say way huge. The newest version of the Swollen Pickle features additional clipping options under the hood that allow you to tweak further, should you feel the need. But out of the box, this fuzz is a ripper capable of searing leads and wall-of-sound chords. Built like a tank, with a reasonable market price, I’m a big fan of this one. It’s great for guitarists interested in a Big Muff-rooted fuzz without committing to that voice exclusively. Definitely check it out!
Mythos Pedals Golden Fleece ($139 street)
Sometimes simple and stupid is the best approach, and it absolutely works with the Golden Fleece. This single-knob, no-nonsense fuzz from Zach Broyles’ company is a fine-tuned machine with a minimum of options. All the tough decision making has already been done and built into a germanium-and-silicon-based circuit. So, don’t let this pedal’s size and lack of additional controls scare you. It is a monster fuzz pedal.
With its single “more” knob (the output volume), touch dynamics, the pickup selection on the guitar, and guitar volume and tone settings play a huge role in the results. It cleans up extremely well and can go from light and crunchy to full-on saturated awesomeness. Tone-wise, it lives in a unique vintage-fuzz sweet spot. Muff-y? It kinda can be, but it has much more clarity and string definition. Fuzz Face-y? Yes, but it’s much smoother, while simultaneously more aggressive. You’d think a fuzz pedal with one knob would be easy to explain, but this pedal just does so dang much. I’m a huge fan of the tones that this stomp offers—especially at $139, and with the tiny amount of precious pedalboard real estate required. Mythos calls it, “your gateway pedal to fuzz.” Fair enough!
Analog Man Sun Face ($195 street)
What’s a list of killer vintage-sounding fuzzes without an Analog Man pedal? It’s no secret that Mike “Analog Man” Piera sits high up on the list of vintage-fuzz experts, and his constantly in-demand pedals (you’ve heard of the King of Tone?) are a direct result of his passion and knowledge of old-school dirt. I could write a whole article on his smartly crafted fuzz pedals alone. But the Sun Face, as the name might lead you to believe, is Analog Man’s take on the legendary Dallas Arbiter Fuzz Face—that little round box championed by guitar heavyweights like Hendrix, Stevie Ray Vaughan, Eric Johnson, and Pete Townshend. But Analog Man doesn’t just make a one-size-fits-all Fuzz Face clone. Piera offers a dozen different variations of the pedal, with a multitude of choices. Both silicon and germanium transistors are available, as well as low- and high-gain options, which are a result of Mike carefully hand-selecting transistors that allow us nerds to get very specific about what flavor of Fuzz Face sound we want in our rig. The Sun Face is a top-quality build from a top-quality builder. You really can’t go wrong with any variation if you’re chasing the vintage-fuzz dragon.
Red River Amplification Bonetender ($199 street)
The Bonetender was created out of a love for the classic MkII Tone Bender circuit, which Sola Sound debuted in 1966. This device has two knobs, three transistors (Russia-made NOS MP41A “flying saucer” transistors, for the super-nerdy), and a name that bears its influence on its sleeve. David Britton of Red River Amplification in Nashville has nailed the classic Tone Bender sound. He hand-picks his PNP germanium transistors to craft a warm, round voice, with insane sustain and exceptional clean-up. This straight-to-the-point 2-knob (dirt and volume) fuzz provides instant joy for players of all skill levels and is easily one of my favorite MkII-inspired fuzz pedals.
By the way, since you’ve seen the terms germanium and silicon come up in this article several times by now, I should probably give a quick explanation of what they are, for fuzz novices. Silicon and germanium transistors are semiconductors that amplify or alter electronic signals, like those produced by your guitar that travel through your cable. Silicon transistors are more modern, and were developed in the 1950s. Germanium transistors were developed in the 1940s, and opened the door to solid-state electronics. The earliest germanium fuzz pedal, the Maestro FZ-1 used by Keith Richards on “Satisfaction,” was introduced in 1962. The first silicon pedal appeared in the late '60s. Generally, silicon is less responsive to guitar volume attenuation but more temperature-stable than germanium, which can be fussy in hot or cold weather, but pedals using either germanium or silicon can blow a hole in the side of a barn. Okay?
ZVEX Fuzz Factory ($319 street)
Where to start with this one? Odds are you know about this pedal. It’s a staple on so many rigs. It has inspired thousands of guitar players, as well as other pedal builders. It has been loved and used by fuzz purveyors like Trent Reznor and Billy Gibbons. And it is a modern classic. It started as a Fuzz Face clone, but the Fuzz Factory quickly carved its own path in the pedal world, though it’s a bit divisive among players due to its chaotic nature. The Fuzz Factory, which debuted in 1995, was one of the first pedals that purposely use feedback-loop-style self-oscillation—something that other builders at the time tried to avoid. But this stomp’s self-oscillation can easily be tamed and is part of what makes it so damn versatile. The Fuzz Factory is perhaps one of the most flexible fuzz pedals ever created, capable of nearly any tone you’ve heard on classic records or sounds you hear in your mind. Ripping Velcro-style Jack White vibes, spikey “Satisfaction” leads, or full-blown wall-of-sound fuzz are all here! If you're not scared of fuzz pedals with more than three knobs, the five on this stomp (volume, gate, compression, drive, and stability) allow you to explore fuzz in new, creative ways.
Benson Amps Stonk Box ($279 street)
Chris Benson quickly went from unknown apprentice at Verellen Amplifiers and repair tech at Old Town Music in Portland, Oregon, to in-demand, consistently backordered boutique amp builder, and for good reason. Also, his contributions to the pedal world have been fantastic—specifically his creation of what he terms “automatic thermal bias technology.” Essentially, he invented a system that regulates and stabilizes the bias of germanium transistors in a pedal, no matter how hot or cold it is outside. This is a big deal! And the Stonk Box? It is a Tone Bender MkI-inspired device that excels in vintage fuzz voices, with tone, volume, filter, and trim controls. It nails the FZ-1, MkI, and Zonk Machine sounds (which are all basically the same thing). It does the sought-after, beautiful, blossoming fuzz sound. And it can surely handle your Keef riffs, but the range of this high-quality build goes well beyond that.
Rude Tech 3MuF-14 Distortion/Fuzz ($255 street)
Jesse Rhew, of Rude Tech in Nashville, really knocked this one out of the park. Taking three well-loved and legendary Sovtek Big Muff circuits—the "Civil War," "Green Russian," and "Black Russian"—and putting them in one enclosure is cool, right? But the modern improvements and additions included in the 3Muf-14 make these classic sounds more usable in any setting. If you’ve played a Big Muff-style circuit, you know it’s very common for your guitar or bass to lose presence as soon as you turn the Muff on in a live-band setting. Because of this, a lot of players run their Muff-style fuzzes into mid-heavy overdrives or EQs, so they don’t get lost in the mix. The 3MuF-14 adds a mid-focused drive circuit with its own footswitch, so your sweet riffs aren't left out of the fun. As you’ve gathered by now, there are lots of killer Big Muff-style circuits out there, but if you’re looking for a gig-able option that offers just enough tweak-ability without menu diving, the 3MuF-14—with volume, tone, and sustain dials, plus toggles for tone and Muff-style selection—should be on your watch list.
But Wait, There’s More!
These are my favorites, but there are dozens more fuzz pedals, at all kinds of price levels and control options, worth investigating. See Ted Drozdowski’s companion story for a rundown of many of these, and, meanwhile, here are a few more pedals that are on my radar right now, and the historic devices or characteristics they emulate.
• JAM Pedals Octaurus (currently sold out): For fans of the Univox Super-Fuzz, Shin-Ei Companion, and Tycobrahe Octavia.
• Seeker Electric Effects SUPA (currently sold out): MkI and MkII Tone Bender
• Yesterday Effects Peach Fuzz ($200 street): Frantone Peach Fuzz
• ThorpyFX Field Marshall ($254 street): Lovetone Big Cheese
• Death By Audio Fuzz War ($180 street): Inspired by the Colorsound Supa Tonebender
• Spaceman Effects Spacerocket (currently sold out): An “intermodulation” fuzz
Charlie Worsham was just wrapping up some tracking down at Sony Studios in Nashville when PG’s John Bohlinger caught up with him for a look at what tools he packs for a recording gig. Worsham had with him some of his most treasured acoustics, electrics, mandolins, banjos, and more, plus a collection of primo picks for all applications. Check out the highlights below.
Brought to you by D’Addario.
Guitar So Nice, He Bought It Twice
This 1963 Martin D-28, gifted to him from his parents, was Worsham’s first serious vintage guitar. Around 12 years ago, he took it into a shop for a refret, and after a freak in-store accident left it in pieces, Worsham accepted a check for the guitar’s value, and walked away.
A while later, he noticed it hanging on the wall of the same store—reassembled and fit for service again. Worsham couldn’t help himself; he bought it back, making it “the guitar so nice, [he] acquired it twice.”
He runs it with D’Addario XS strings and likes bluegrass gauges: mediums for the E, A, and D strings, and lights for the G, B, and high E strings. It’s kitted out with an LR Baggs HiFi pickup. And the scratches around the soundhole and pickguard? Those came courtesy of John Osborne’s heavy picking hand.
Check, Please
Worsham reckons he’s probably played this treasured Gibson J-50 on more records than any other guitar he owns. After he took the check from the busted Martin D-28, he used it to buy this one.
Family Jewel
This Parker mando used to belong to John Osborne, Worsham’s former bandmate. Worsham was always borrowing this mandolin, so when Osborne decided to sell it, Worsham picked it up to keep it in the family.
Burkett from ’Bama
This mini Burkett was built by luthier James Burkett in Alabama. Its nut is equivalent to a capo on the third fret of a regular acoustic.
Tune in to the full video to see Worsham’s Ohm open-back banjo, P-90-equipped Gibson mandolin, an Osborne-owned Strat, and a super-special wedding-gift ES-335 from Vince Gill.
Tweed Fit for a Prince(ton)
Worsham took Tom Bukovac’s wisdom and got himself a Fender Princeton Reverb, which he still loves, and he runs it alongside a Nashville Amp Works clone of a golden-era tweed Fender Deluxe.
Charlie Worsham’s Pedalboard
At his feet, Worsham runs a pedalboard with a Sonic Research ST-300 tuner, Browne Amplification Protein, Mythos Mjolnir, Guyatone ST2, Electro-Harmonix Canyon, Neunaber Immerse, Strymon El Capistan, and Chase Bliss Warped Vinyl HiFi.
