The Terrain Deluxe is a Harmonic Tremolo with Tap Tempo, featuring a high fidelity all analog signal path using LightDependent Resistors (LDRs) for modulation. The Harmonic Tremolo mode uses an electronic crossover to split the signal into high and low frequency components.These are modulated 180 degrees out of phase and then re-combined creating a wet, lush tone. Speaking of tone, theTone control pans between the high and low frequency signals, going from full treble to full bass and everything in between. In the unlikely event that you get tired of the beautiful Harmonic Tremolo there is a Normal / Harmonic mode switch. In Normal Mode the high and low components are modulated together creating a traditional tremolo sound.
There are Speed, Depth, and Gain controls, and a Waveform switch to select between square, sine, and triangle waveforms.The Tap Tempo foot switch works win conjunction with the Tempo Multiplier switch allowing you to create quarter note, eight note, and eight note triplet modulations by just tapping the base tempo. The two tempo LEDs above the footswitch flash together in for Normal mode and 180 degrees out of phase in Harmonic mode.Finally, there are two independent expression pedal inputs: one each for Speed and Depth.
• Harmonic Tremolo with Tap Tempo.
• High fidelity all-analog signal path using LDRs.• Speed, Depth, and Gain controls.
• Tone control that sweeps between high and low frequency signals (center is flat).
• Normal / Harmonic mode switch.
• Sine, Square, and Triangle waveform switch.
• Tap Tempo footswitch with Tempo Multiplier switch.
• Independent expression pedal inputs for Speed and Depth controls.
Building on the foundation of the company’s acclaimed pedalkits, StewMac has introduced a line of ready-to-play, fully finished guitar effects pedals.
The newly launched models include StewMac’s four most popular pedal designs: the Sun Fuzz; Lightcycle Phasor II optical phaser; Two Kings Boost dual overdrive; and Ghost Drive transparent overdrive. Each pedal delivers classic tone at an incredible price.
There have been countless replicas and reimaginations of the classic Fuzz Face pedal. StewMac’s Sun Fuzz gives you the control and tone shaping you've always wanted from the originals, and it’s a must-have for fans of Hendrix, Clapton, or Gilmour’s tone.
This circuit is one of the foundational tones for electric guitar, but the germanium powered originals can be hard to control and don't play nice with many pickups and amps—even temperature can completely change the tone! To create a more predictable, controllable, reliable tone, we've swapped the germanium transistor for a silicon BC-108, giving the pedal a brighter tone, more gain, and enhanced touch sensitivity.
Priced at $99.99, the Sun Fuzz is a no-brainer for fuzz fans who don’t want to shell out $200+ for the originals. Key features include:
Improved bias control and tone shaping compared to the originals.
Silicon BD-108 transistor.
Versatile fuzz with simple controls for volume, fuzz, and tone.
Sounds great with humbuckers, single-coils, and P-90s alike.
Inspired by one of the most sought-after dual overdrives on the market, players like John Petrucci, Gary Clark Jr., Samantha Fish, and Warren Haynes have raved about the originator of this circuit, the King of Tone. Now, you don’t have to wait to add this circuit to your rig. StewMac’s Two Kings is transparent but still warm and gritty, with a full range of frequencies available—no matter the setting. It won't overpower the unique tone of your guitar and amp—it just makes it better.
The Two Kings is actually two pedals in one, with selectable boost and distortion through internal dip switches. The two sides of the pedal are completely independent—it's easy to find the sweet spot for each side. With knobs for gain, volume, and tone you can get anything from simple boost, gritty overdrive, and even distortion in a flash. If you want to go deep, you can further tailor the sound with the internal controls for infinite tone tweaking.
Priced at $159.99, the Two Kings is an affordable and authentic alternative to the pricey, hard-to-get original. Key features include:
2-in-1 pedal.
Maintains core tone of guitar and amp.
Effortlessly provides boost, gritty overdrive, and distortion.
This isn’t just another phase shifter—it’s the unmistakable sound of deep, liquid movement that defined an era. Inspired by the MuTron Phasor II from the 1970’s this studio-quality, all-analog optical phase circuit set the gold standard for smooth, sweeping modulation. StewMac has recreated this timeless classic to bring your tone to life with the same lush, organic depth that graced the pedalboards of legends. You can recreate those complicated textures live—from a rotary speaker shimmer to wild spacey soundscapes, every knob twist sparks inspiration. On the front are controls for depth, rate, and feedback, letting you dial in anything from subtle swirl to rapid tremolo and synthesizer sounds. For even more flexibility, two internal controls let you dial in the sweep and intensity of the phased signal.
Priced At $119.99, the Lightcycle Phasor II is an authentic and affordable alternative to the original. Key features include:
Studio-quality optical phaser.
Controls for depth, rate, and feedback.
Two internal controls to adjust the sweep and intensity of the phased signal.
Not just another “klone”, the StewMac Ghost Drive pedal is astonishingly close to the famed Klon Centaur Professional Overdrive. StewMac scoured the globe to source the nearly impossible to find (electronically identical) 1N34A germanium diodes that many claim were the heart and soul of the mojo behind the original Klon. Also, unlike so many modern klones that rely on surface mount components, the Ghost Drive is pure old school using through-hole components and traditional solder joints. The Klon was made famous by countless players like Joe Perry, Mike McCready, Joe Bonamassa, John Mayer, Nels Cline and more. Like the original, StewMac’s Ghost Drive is extremely easy to use: just gain, treble, and output. The gain is where the magic is by adding sweet saturation and harmonics while retaining the character of your amp. The treble acts as a boost or cut, allowing you to dial in the perfect mid-range for your tone.
Priced at just $129.99, the StewMac Ghost Drive provides a nearly identical tone for just a fraction of the price of the originals. Key features include:
Through-hole components and traditional solder joints just like the originals.
The electronic identical 1N34A germanium diodes in the originals.
Works great as a clean boost as well as a transparent overdrive.
Buffered bypass.

A 3-in-1 wah, envelope follower, and envelope controller that opens up a huge range of filtering possibilities.
As an avid—perhaps rabid—musical psychedelicist, I’ve had a lot of wah in my life. Maybe too much. In recent years, I seem to have had my own personal version of the rock world’s 1968 epiphany, where everyone ditched their wah and fuzz, moved to the country, and put Music from Big Pinkon constant replay.
Recently, though, I’ve been in touch with my wah side again—this time by way ofJJ Cale’s chilled out swells andCurtis Mayfield’s mellower wah flourishes. And through these applications of treadle-actuated filtering, I’ve rekindled my love for the more psychotic side of the effect. Vox’s V863-CA will happily wind along either the gentle path or the hard road. It has a nuanced filter taper that makes slow, focused sweeps sound sweet and vocal, and it responds to quick-twitch moves with precision. But the real magic in the V863-CA is its combination of envelope generator (auto wah) and envelope follower functions, as well as its ability to switch between wah and the two filtering modes merely by lifting your foot from the treadle.
It Just Takes A Touch
You can only use either the envelope generator/wah combination or the envelope follower/wah combo at any given time—a small price to pay for the versatility at hand here. You can, however, select between those two modes with a small mini toggle on the lower left side of the enclosure—which, incidentally, seems well out of the way of accidental triggering. There is a third position for wah only, which is useful for accessing cocked wah tones. But you can switch any of the effects into bypass mode with a click in the toe-down position.
Vox’s V863-CA will happily wind along either the gentle path or the hard road.
Inspired by Dead and Company’s recent shows celebrating the Grateful Dead’s 60th anniversary, I explored the envelope follower section of the V863-CA in honor of Jerry Garcia. The V863-CA performs admirably in this capacity. Using the polarity switch, you can shape the filter’s reaction to a dynamic trigger. In one mode the filter’s voice opens with a “wow”-like tonality; in the opposite polarity it yields a snappier effect. It’s a pretty sweet-sounding envelope filter, too—particularly in the more open, vowelly, Garcia-like mode. The sensitivity control, which governs the filter’s reaction to picking dynamics, isn’t the most nuanced, and I preferred to keep the sensitivity wide open and control the sound via my picking and guitar volume (which can dull the dynamic response if you turn down too much). Still, the biggest thrill of using the envelope follower mode was the ability to launch from a chilled, quacky, Garcia run to Eddie Hazel “Maggot Brain” intensity just by putting my foot on the treadle. This is a genuinely inventive feature that will open up possibilities to players outside the psychedelic sphere.
The envelope generator, or auto wah function, can be shaped with both the decay control and the attack knob, which manipulate the filter’s reactivity. (Both knobs have useful center detents). Between the two controls you can craft syrupy response for spacey, slow jams (delicious with loads of delay) or snappy, funky interactions that will keep up with rapid-fire Nile Rodgers-style licks.
At $279, Vox’s Vietnam-made V863-CA seems expensive until you dig deep into its bag of tricks. And though it might appear specialized, I had little problem finding novel uses of the combination effects that broke the funky and acid-fried wah molds and led to more unusual ends. But the coolest part of the V863-CA experience remains the ability to seamlessly move from wah to filtering functions simply by lifting one’s foot. It’s a smart way to shift between verse, chorus, and solo segments without tap dancing between multiple pedals. The same functionality can generate dramatic changes in mood and dynamic, inspiring whole compositions and arrangements. In that respect, the V863-CA delivers value in abundance.
Our columnist, invoking the truth on a pedal steel like a medium with an Ouija board.
In the 1999 cult classic Mystery Men, Invisible Boy has a superpower that’s as hilarious as it is relatable: He’s invisible, but only when no one’s looking. The moment eyes are on him, he’s just a kid in a cape, exposed and ordinary. Musicians, doesn’t that hit home? When it’s just you and your guitar, the music flows like a river—raw, unfiltered, alive. But flip on the studio’s red light or face a sea of cell phones at a gig, and that river can dry up fast. It’s the red light paradox: The act of capturing inspiration often chokes it.
Players like Marcus King, Masayoshi Takanaka, and Tom Bukovac seem to live in that effortless zone, channeling endless streams of soulful licks. Alone in a room, you might tap into that, too—those late-night jams where riffs cascade and ideas feel infinite. No stakes, no judgment. Only creation. But in the studio, that red light is a judge with a gavel. Every note feels etched in stone, ready for eternal scrutiny. The ticking clock, the producer’s glance, the knowledge that a single take could live forever—it’s enough to stall the flow.
I’ll never forget filming a Rig Rundown with Thom Bresh in 2020. Thom was an absolute legend with talent that drove an incredible seven-decade career. Before we started, I said, “Hey Thom, want to play something going into the interview?” He paused, grinned, and replied, “Been playing my entire life, but the minute somebody asks me to play, I got nothing. My mind goes blank.” If a giant like Bresh could feel that pressure, what hope is there for the rest of us mere mortals? It’s proof that the red light doesn’t discriminate.
“It’s not about nailing every note; it’s about capturing something true.”
Live music, though, is a different beast. There’s freedom in the fleeting moment. The crowd’s energy, the vibe with bandmates, the knowledge that a flubbed note vanishes by the next song—it all invites risk. I’ve seen players, myself included, get bold onstage in ways we’d never try in the studio. You’ll stretch a phrase, chase a wild harmony, or lean into a bend that might not land, because it’s yours and it’s gone in minutes. It’s a tightrope walk with a net, letting you attempt crazier tricks.
In the studio, that net’s gone. The red light means evidence—permanent, unerasable. Every take is a potential exhibit in the court of public opinion. (Even onstage now, since a phone clip can haunt you online until our hypothetical ape overlords unplug the internet.) It makes you play it safe. I do it—sticking to solid takes to avoid being “that guy” holding up the session. If the bassist or keyboardist wants another pass, I’m right there—not always because I hate my take, but for insurance. Just in case there’s a gremlin in the mix—a flubbed note, a shaky vibrato, or a phrase that felt cool but now sticks out like a bad tattoo.
That self-consciousness isn’t just about avoiding mistakes; it’s the weight of permanence. Live, a missed note is usually a blip, forgotten by the encore. In the studio, it’s a ghost that could haunt you. I’ve heard players nail a take only to spend hours second-guessing it, not because it’s bad, but because it might not be perfect. And perfection, we all know, kills vibe. The studio’s a paradox: it’s where you immortalize art, but the process can drain its soul.
”That self-consciousness isn’t just about avoiding mistakes; it’s the weight of permanence.”
So how do you beat the red light curse? Some players treat the studio like a live gig—dim the lights, imagine a crowd, or track live off the floor to capture that loose, communal energy. Others prep relentlessly, woodshedding parts so the light can’t rattle them. Bukovac, in a Homeskoolin’ video, talks about playing like you’re “just messing around,” even in high-stakes sessions. Easier for a guy who bleeds licks, but there’s truth there: The less you fear the light, the freer you play. I’ve tried picturing it as a vibe check, not a verdict, but it’s tough when Thom Bresh’s words echo. Even legends go blank under pressure.
Maybe the answer lies in embracing the imperfection the red light exposes. Live, we forgive ourselves because the moment’s gone. In the studio, we must forgive ourselves knowing the moment’s forever. It’s not about nailing every note; it’s about capturing something true. Next time you’re in the booth, staring down that glowing red eye, channel Invisible Boy. Shrug off the gaze and play like no one’s watching. Because the only judgment that matters is whether the music moves you. If it does, it’ll move someone else, too
