Walrus Audio Mako M1
walrusaudio.com
Depending on your appetite for adventure, the Walrus Audio M1 modulation machine can look like a thrill ride or a very nasty little thing. The knobs and switches—as well as the graphics and text that describe their function—are packed like sardines onto the face of the pedal. And depending on your settings, the two bright LEDs can pulse like an entire Fillmore liquid light show stuffed into two little fish eyes.
If simplicity is your muse for the moment, M1 might not be the best travelling pal. But before you move on too fast, plug the M1 in. Twist any one of those knobs any direction you’d like and play a simple D chord. My guess is that, as terrifying as the M1 might look, it’ll take just that one strum to hook you. Because the M1 is fun. Lots of fun. And even if you never use its deep and impressive sound-crafting tools to fullest potential, the M1’s sounds and smart design still make it a cornucopia of easy-to-source, immersive modulations.

Damn the Navigation Aids! Full Speed Ahead!
I could spend most of the space in this review describing the primary and secondary functions governed by the M1’s 11 switches, knobs, and toggles (not to mention the stereo I/O, MIDI in/thru jacks, and a USB jack for firmware updates). But the M1 is deep enough that the job is best left to the thorough, downloadable manual available on the Walrus web site. This excellent piece of documentation is worth cruising even before you buy the M1 to see if the deeper functions merit your investment. However, if you choose to take the plunge and explore M1 as intuitively as possible, the manual is a well-written map for your trip through modulation wonderland. Should you meander too far from the trail, it’ll likely get you back on track fast.
At the M1s core are six modulation voices. Chorus, phase, tremolo, vibrato, and rotary speaker sounds are all represented along with a modulated filter setting. Each voice spans pretty and demented sounds, and each is full of surprises. In their most traditional incarnations, the digital emulations of analog effects are beautifully accurate and replete with rich overtone detail. Secondary functions abound on the M1 and making the most of them really does require some study of the manual. But one of the best things about the M1’s designs is that if you get into the weeds with these secondary functions, it’s generally easy to get back on track using the pedal’s rate and depth modes, which lends a sense that it’s OK to proceed fearlessly.
Even in small measures, many of the lo-fi sounds can shape straightforward modulation in very cool ways.
Diving for Pearls
If and when you do get the courage to explore M1’s deeper possibilities, there’s much to enjoy. The primary path to this deeper functionality comes via the tweak and tune knobs and their associated switches. Both controls change function depending on what you select with the switch below. Tweak enables you to choose between sine, triangle, and square waveshapes; quarter-note, triplet, and eighth-note tap divisions (there are a wealth of subtle rhythmic textures here); or one of three modes for each basic program. These modes include tri-chorus in chorus mode, different horn/drum virtual miking configurations in rotary mode, tape- and warped-vinyl-inspired vibratos, harmonic tremolo, and high, low, and bandpass filters in the filter program, just to name a few. On the tune side, the 3-way switch enables the knob to be configured for adjustments to tone, wave symmetry, or “X” functions that include everything from stereo phase effects to phaser feedback and tape flutter. Should you start to worry about losing your place as you get into these deeper realms, remember that the M1 has the capacity for nine onboard presets (easily accessed using the A/B/C bank switch and the two footswitches in concert) and 128 total presets via MIDI.
Yet another realm of tone possibilities lives in the lo-fi strata of functionality. Accessing these functions on the fly is a little more cumbersome as they require selecting a function via the 3-way switch, holding down the bypass footswitch, and then using the tweak or tune knob to add the lo-fi element to taste. Not all these functions will serve all players. A lot of them tend toward the noisy, junky, and weird side of the sound spectrum. But even in small measures, many of the lo-fi sounds, like age, space (reverb), drive, and noise, can shape straightforward modulation in very cool ways. Once set up it’s easy to mix in these textures with the lo-fi knob. Don’t be afraid to set up highly weird sounds and add them incrementally.
The Verdict
One of the M1’s great achievements is that it can serve two muses—the obsessive, micro-level sound designer, and the reckless, intuitive sound tripper—simultaneously. This is no insignificant thing. And Walrus deserves praise for accomplishing this design feat in a compact stompbox. But the highest praise may be due for Walrus’s ability to make M1 so much fun and so sonically satisfying. And Walrus’s ability to walk this engineering and design tightrope makes the otherwise steep-looking $349 price a relative bargain.
Multiple modulation modes and malleable voices cement a venerable pedal’s classic status.
Huge range of mellow to immersive modulation sounds. Easy to use. Stereo output. Useful input gain control.
Can sound thin compared to many analog chorus and flange classics.

TC Electronic SCF Gold
tcelectronic.com
When you consider stompboxes that have achieved ubiquity and longevity, images of Tube Screamers, Big Muffs, or Boss’ DD series delays probably flash before your eyes. It’s less likely that TC Electronic’s Stereo Chorus Flanger comes to mind. But when you consider that its fundamental architecture has remained essentially unchanged since 1976 and that it has consistently satisfied persnickety tone hounds like Eric Johnson, it’s hard to not be dazzled by its staying power—or wonder what makes it such an indispensable staple for so many players.
The latest incarnation of the Stereo Chorus Flanger, the SCF Gold, underscores the timelessness of TC’s classic. And the richness of its modulations, its broad versatility, and very accessible price still add up to a most appealing multi-modulator.
Complex Sounds from Simple Controls
Pedals that combine chorus, flange, and vibrato aren’t uncommon. But given the fundamental similarities between the effects, it’s curious we don’t see more boxes that bundle the three. Obviously, specialization enables enhanced control and more refined and radical results. But for gigging guitarists and studio players that need to work fast and intuitively, there is an undeniable appeal in a pedal that covers all the bases competently.
One beautiful feature of the SCF Gold’s ageless design is the simplicity of the control set. That simplicity is essential, however, because the three controls are highly interactive and vary in feel and function depending on the mode you use.
The speed knob spans rates ranging from an ultra-lazy 10 seconds per cycle to fast, rotary-style 10-cycles-per-second pulses. The width control governs the delay time between waveforms. The intensity control is the shape shifter of the bunch. In chorus mode, it’s effectively a wet/dry blend. In flanger mode it becomes a feedback control. And in pitch modulation mode it regulates the balance between vibrato and chorus effects. The input gain control situated just below the mode switch may look less vital, but the grit, body, and volume that it adds to a signal transforms many modulations into thicker, less clinical, and sometimes more organic and cohesive sounds—though that sometimes comes at the expense of the SCF’s excellent focus and clarity. It’s also critical for overcoming some of the volume loss that you perceive at intense modulation settings.
In both live and studio settings, the extra top-end clarity makes the SCF Gold pop.
Clear-Eyed and Wobbling
If you had to pick a single characteristic that sets the SCF Gold apart from other classic analog choruses and flangers, and the contemporary pedals that imitate them, it’s the TC’s focus and clarity, particularly in the high-mid and high frequencies. Many analog chorus pedals end up with a fairly dark voice—partly as a function of bucket brigade circuit design, but also, perhaps, in an attempt to tame resonant peaks and better simulate the more liquid qualities of rotary speakers and tape flange. I love those smoky modulation colors. But there are times, especially when I’m working with a dense arrangement, that I want a chorus to sit more present and distinctly in its corner. The SCF Gold’s relatively bright voice enables these simultaneously more prominent and less bossy tones. For players that revere the heavy, unmistakably underwater sounds of Electro-Harmonix’s Electric Mistress flanger and Polychorus or the Boss CE-1 chorus, the TC might sound comparatively thin. But I love the fidelity I can hear in its less murky modulations. And in both live and studio settings, the extra top-end clarity makes the SCF Gold pop, which is killer for underpinning ’80s-style applications and modern indie-pop hooks.
There are countless textures to uncover among the SCF Gold’s modulations, including a wealth of familiar classic chorus and flange sounds. But there are scores of surprising highlights, too. Mating fast and fairly intense vibrato pulses to high input gain settings, for instance, generates a fair approximation of Magnatone amp vibrato in a pinch, and a nice Boss VB-2 style throb in cleaner settings. And high flange speeds coupled with modest width settings create gently pulsing waveforms that are redolent with hints of phase, tremolo, and delay. Adding intensity in this setting adds progressively more vowely and metallic overtones—yielding some of the coolest sounds the pedal has to offer.
Among the chorus sounds, the most traditional late-’70s/early-’80s modulations were the most enticing and addictive to my ear. But the chorus also dishes stylish approximations of 12-string electric (particularly with a bright Fender bridge single-coil out front) and trippy faux-rotary sounds, which sound extra immersive in stereo.
The Verdict
If you’re a gigging player, the utility and jack-of-all-trades flexibility of the SCF Gold could make it indispensable. And if you’re into pedalboard economy, it could conceivably replace multiple pedals. Whether you’re chasing the most versatile modulator possible or just authentic ’70s to ’80s chorus and flange sounds, the SCF Gold’s $149 price represents an excellent value. The modulations may not be as deep or queasy as those you’ll hear from other classic analog choruses and flangers. But the low noise floor and focused EQ profile make it easier to wrangle in many musical situations.
Does it better the many variations of the SCF that have come before it? Well, with crown-mounted 9V power and an input gain circuit that bumps the pedal’s already considerable headroom, we’d have to say yes. However minor and incremental these improvements may be, they are reason enough to investigate this fun, multifaceted, sweet sounding, and super affordable multi-modulation device if you haven’t already had the pleasure.
