Walrus Monumental Harmonic Stereo Tremolo Review

Walrus Monumental Harmonic Stereo Tremolo Review

Complex tremolo sounds combine in stereo fields that can sound more like underwater swimming than swamp-rocking.

Lovely washes of complex tremolo textures that can be spread across a stereo field. High-quality build. Useful stereo pan control. Practical boost control.

High depth settings could be more intense for some voices. Some harmonic/optical blends can be subtle, compromising their essence.

Among fellow psychedelic music-making chums in the ’90s, few tools were quite as essential as a Boss PN-2 Tremolo Pan. Few of us had two amplifiers with which we could make use of one. But if you could borrow an amp, you could make even the lamest riff sound mind-bending.


Walrus Audio’s Monumental Harmonic Stereo Tremolo is far from the only modern tremolo pedal that offers stereo panning. And it’s one of many that digitally approximates the elastic, phasey sound of brown-panel Fender harmonic tremolo. But the Monumental’s economical design and compact dimensions conjure memories of PN-2s I’ve known and missed. It brims with features an old PN-2 user could only dream of in the midst of a stereo amp reverie: the harmonic tremolo, a more traditional optical tremolo-style voice, the ability to blend the two, six wave shape options, and a subdivision switch that enables precise rhythmic variations on any given modulation pattern.

Rhythms Carved in Rock

The Monumental is, as any Walrus-watcher will know, is an evolution of theMonument, which was built around harmonic and optical-inspired tremolo voices, and features tap-tempo, subdivisions, and five waveform types. So, the big news here is the stereo capacity, presets, and the ability to blend the harmonic and optical tremolo types. You’ll pay 60 extra bucks for these extended capabilities. But if you really get into using tr-molo to its fullest potential, these are no small matters.

The big news here is the stereo capacity, presets, and the ability to blend the harmonic and optical tremolo types.”

The Monumental uses the same-sized enclosure as the Monument V2. The only real drawback from this layout is the proximity of the tap-tempo switch to the bypass, and, as I was reminded at a jam last week, I for one, can easily miss my footswitch target if I’m deeply involved in a musical moment. That issue aside, the Monumental is impressive for the way it accommodates stereo in and out jacks, a tap and expression pedal jack, six knobs for volume, wave shape, stereo pan spread, rate, depth, and the optical/harmonic blend. The subdivision button is situated just below these and is easy to access and operate. None of it, save for the footswitches, feels cramped or difficult to navigate.

Soaring Skyward

It’s good that Walrus added presets to the Monumental, because while it can often seem subtle, the deeper you venture into the possible textures, the more detail and difference you hear among them. Waveforms like the square and sine wave sound great at low- and medium-depth settings. Other options benefit from a more-aggressive depth setting. I tended to like the optical and harmonic tremolo voices in their purest forms, but you can find many intricacies to probe and unravel in the blended settings. Some of those differences might go missing in the wash of a dense arrangement, but when they breathe in more spacious musical settings they are lovely. This is especially true when you use the pedal in stereo.

If you don’t intend to use the Monumental in stereo, you should carefully consider whether the presets and blendable voices merit the extra expenditure. For many, they will. But using the Momumental in mono alone means missing out on some of the pedal’s most infectious sounds. While square, sine, sawtooth, and random waveforms sound particularly exciting here, the other waveform types bubble and percolate all over the stereo field, often sounding percussive in optical mode and woozy in harmonic settings. Maximum depth settings sound particularly immersive. You can also enhance the effects of a dramatic stereo spread by equalizing your two amps differently. I boosted the bass and removed most of the treble from a black-panel Fender and did the inverse with a Vox-style amp for my stereo experiments. The resulting combination of detailed pick attack, strong transients, and peaky top-end popping over a fat, rubbery foundation sounded liquid and surreal—even with the pronounced treble peaks in the mix—making an already basically rich tremolo voice sound extra three-dimensional. By the way, yes, I tried the “How Soon Is Now” riff through a stereo setup. And yep, it sounded fantastic.

The Verdict

At $279, you will want to ask yourself how much tremolo you intend to use before you invest in the Monumental. There are certainly simpler ways to swamp-rock. The Monumental also lives at the more expensive end of its category—coming in a little pricier than pedals like the Keeley Hydra and the crazy-feature-rich EHX Super Pulsar. But there’s no contesting the high quality of this USA-made pedal or the thoughtful way the sounds within were conceived. And studio rats and texture obsessives that love the sensation of swimming in a stereo field may find the Monumental worth every penny.

The perennial appeal of one of Gibson’s most accessible Les Pauls is stoked anew in this feature-rich version.

Lots of nice vintage touches and features that evoke the upmarket Les Paul Standard at a fraction of the price. Coil-splitting capability.

A thicker neck profile would be a cool option and distinguishing feature.

Effectively a no-frills version of theLes Paul Standard, the Les Paul Studio has been a fixture of Gibson product rosters since 1983, which says something about the enduring, and robust, appeal for affordable alternatives to the iconic original. The notion behind the original Les Paul Studio was that it didn’t matter how a guitar looked when you were using it in the studio. Who cares about a flamed top, binding, inlays, and other deluxe cosmetics in a session as long as it sounds and feels good?

After a 14-year break in making solo recordings, the Louisiana guitar hero returns to the bayou and re-emerges with a new album, the rock, soul, and Cajun-flavoredI Hear Thunder.

The words “honesty” and “authenticity” recur often during conversation with Tab Benoit, the Houma, Louisiana-born blues vocalist, guitarist, and songwriter. They are the driving factors in the projects he chooses, and in his playing, singing, and compositions. Despite being acclaimed as a blues-guitar hero since his ’80s days as a teen prodigy playing at Tabby Thomas’ legendary, downhome Blues Box club in Baton Rouge, Benoit shuns the notion of stardom. Indeed, one might also add simplicity and consistency as other qualities he values, reflected in the roughly 250 shows a year he’s performed with his hard-driving trio for over two decades, except for the Covid shutdown.
