Great Eastern FX

Though some musicians consider it a chore, I relish the creative possibilities associated with mixing a song or record. Working with the Great Eastern FX XO Variable Crossover feels a lot like the process of experimental mixing using EQ and outboard effects. The concept is simple: The XO splits the low and high frequencies from your input into two separate bands, which are routed via corresponding send and return jacks to different effects or series of them.
Depending on how you set the crossover frequency, the return balance, dry blend, and phase, you can fluidly shape, blend, and move between sounds that are subtly different or radically deconstructed. On the surface, it might look and sound like a cumbersome process. In reality, itās intuitive, fun, and full of surprises
Ā Fear Not the Frequency Shift
The XOās control set will probably look alien to most guitarists. The largest knob controls the crossover frequency, which determines the point at which the full frequency band is divided and sent to the low and high send and return. The range button just to its right selects two frequency ranges: 50 to 600 Hz, or 300 Hz to 3.4 kHz. The first is recommended for use with bass, the second for guitar, but you can experiment with either setting for any instrument. The return balance knob sets the relative levels of the two effects returns and the dry blend knob performs its namesake task. The phase button can be used to either correct phase issues when the two bands are out of phase or applied creatively to fashion out-of-phase variations on a sound. A very useful send button, meanwhile, switches the high and low sends, enabling instantaneous selection of mirror-image frequency and effects mixes.
Mutating Tone Tangles
My first experiments with the XO were simple: sending the low band to a delay with long repeats and the high band to another delay with fast repeats, lurking just at the brink of oscillation. The ways I could blend these divided and reconstituted tone composites were often unexpected, surprising, and totally inspiring. I could set up signals that found trebly repeats hovering at the edge of feedback, while low and low-mid frequencies (which can overwhelm a self-oscillating signal) provided a fat foundation for the resonant, ringing top endāa totally cool sound that responded in really interesting ways to picking dynamics and different rhythmic patterns. In a modification of that formula, I routed an intensely throbbing Vox Repeat Percussion clone, slow-sweeping phaser, and long-repeat delay to the low band and assigned a clean, heavily compressed, slapback to the high frequencies. In this configuration, simple folk-rock chords and melodic lead lines took on complex, alien alter egos, sometimes sounding like two playersāone handling a bubbling bass synth, and a guitarist carrying the tune via the clear detailed high end. When the pulsing low end got tiresome, it was easy to dial in more dry signal via the dry-blend knob or dial in a mix favoring the tighter, chiming high band.
āSimple folk-rock chords and melodic lead lines took on complex, alien alter egos, sometimes sounding like two players.ā
The spins you can put on these recipes are endless. Situating an octave-down pedal amid the tremolo and phaser made the two bands even more distinctive and heightened the illusion of a guitarist and synth player working together. You can mix fuzzy, thumping low end with ringing and heavily chorused top-end output. Or you can blend two similar but distinct effects to create oddly chorused and powerful widescreen tonalities.
The cool part of all this potential is that it can be realized with a single amp and just a few pedals. Some of my most radical sounds came via just four or five pedals including the XO, which adds up to a very modest and portable array, all things considered. Players that work with pedalboards that count stomps in the double digits could disappear in labyrinths of sound that are as immersive as those afforded by synthesis. And while XO is, after some practice, easy to control, the new, chaotic molecular reactions provoked by unorthodox stimulation of your pedals all but guarantees unique results. You will definitely find new sounds and new ways to play and compose here.
The Verdict
The XO Variable Crossover is more likely to see service as a studio tool than become a staple of live setups, though plenty of courageous musicians will find it practical in that environment. Although the mechanics and principles behind its workings can seem complex at first, it can be used effectively and dramatically with just a few stompboxes. The sounds and voices it can extract from, say, a phaser and a delay are exponentially greater in number than what youād get by simply using two such effects in series, even if some of them are subtle. And the ability to manipulate and warp these sounds on the fly with the XOās elegant, simple control interface could bring out your inner Lee āScratchā Perry or DJ Shadowācreating new moods, scenes, and tapestries that can turn a simple song or riff into a moving, mutable, and flowing tone story.

Warm Audio Pedal76

Though compressors are often used to add excitement to flat tones, pedal compressors for guitar are often ā¦ boring. Not so theWarm Audio Pedal76. The FET-driven, CineMag transformer-equipped Pedal76 is fun to look at, fun to operate, and fun to experiment with. Well, maybe itās not fun fitting it on a pedalboardāat a little less than 6.5ā wide and about 3.25ā tall, itās big. But its potential to enliven your guitar sounds is also pretty huge.
Warm Audio already builds a very authentic and inexpensive clone of the Urei 1176, theWA76. But the font used for the modelās name, its control layout, and its dimensions all suggest a clone of Origin Effectsā much-admired first-generation Cali76, which makes this a sort of clone of an homage. Much of the 1176ās essence is retained in that evolution, however. The Pedal76 also approximates the 1176ās operational feel. The generous control spacing and the satisfying resistance in the knobs means fast, precise adjustments, which, in turn, invite fine-tuning and experimentation.
Well-worn 1176 formulas deliver very satisfying results from the Pedal76. The 10ā2ā4 recipe (the numbers correspond to compression ratio and āclockā positions on the ratio, attack, and release controls, respectively) illuminates lifeless tonesāadding body without flab, and an effervescent, sparkly color that preserves dynamics and overtones. Less subtle compression tricks sound fantastic, too. Drive from aggressive input levels is growling and thick but retains brightness and nuance. Heavy-duty compression ratios combined with fast attack and slow release times lend otherworldly sustain to jangly parts. Impractically large? Maybe. But Iād happily consider bumping the rest of my gain devices for the Pedal76.

EarthQuaker Silos
earthquakerdevices.com
There is something satisfying, even comforting, about encountering a product of any kind that is greater than the sum of its partsāthings that embody a convergence of good design decisions, solid engineering, and empathy for users that considers their budgets and real-world needs. You feel some of that spirit inEarthQuakerās new Silos digital delay. Itās easy to use, its tone variations are practical and can provoke very different creative reactions, and at $149 itās very inexpensive, particularly when you consider its utility.
Silos features six presets, tap tempo, one full second of delay time, and three voicesātwo of which are styled after bucket-brigade and tape-delay sounds. In the $150 price category, itās not unusual for a digital delay to leave some number of those functions out. And spending the same money on a true-analog alternative usually means warm, enveloping sounds but limited functionality and delay time. Silos, improbably perhaps, offers a very elegant solution to this canāt-have-it-all dilemma in a U.S.-made effect.
A More Complete Cobbling Together
Silosā utility is bolstered by a very unintimidating control set, which is streamlined and approachable. Three of those controls are dedicated to the same mix, time, and repeats controls you see on any delay. But saving a preset to one of the six spots on the rotary preset dial is as easy as holding the green/red illuminated button just below the mix and preset knobs. And you certainly wonāt get lost in the weeds if you move to the 3-position toggle, which switches between a clear ādigitalā voice, darker āanalogā voice, and a ātapeā voice which is darker still.
āThe three voices offer discernibly different response to gain devices.ā
One might suspect that a tone control for the repeats offers similar functionality as the voice toggle switch. But while itās true that the most obvious audible differences between digital, BBD, and tape delays are apparent in the relative fidelity and darkness of their echoes, the Silosā three voices behave differently in ways that are more complex than lighter or duskier tonality. For instance, the digital voice will never exhibit runaway oscillation, even at maximum mix and repeat settings. Instead, repeats fade out after about six seconds (at the fastest time settings) or create sleepy layers of slow-decaying repeats that enhance detail in complex, sprawling, loop-like melodic phrases. The analog voice and tape voice, on the other hand, will happily feed back to psychotic extremes. Both also offer satisfying sensitivity to real-time, on-the-fly adjustments. For example, I was tickled with how I could generate Apocalypse Now helicopter-chop effects and fade them in and out of prominence as if they were approaching or receding in proximityāan effect made easier still if you assign an expression pedal to the mix control. This kind of interactivity is what makes analog machines like the Echoplex, Space Echo, and Memory Man transcend mere delay status, and the sensitivity and just-right resistance make the process of manipulating repeats endlessly engaging.
Doesn't Flinch at Filth
EarthQuaker makes a point of highlighting the Silosā affinity for dirty and distorted sounds. I did not notice that it behaved light-years better than other delays in this regard. But the three voices most definitely offer discernibly different responses to gain devices. The super-clear first repeat in the digital mode lends clarity and melodic focus, even to hectic, unpredictable, fractured fuzzes. The analog voice, which EQD says is inspired by the tone makeup of a 1980s-vintage, Japan-made KMD bucket brigade echo, handles fuzz forgivingly inasmuch as its repeats fade warmly and evenly, but the strong midrange also keeps many overtones present as the echoes fade. The tape voice, which uses aMaestro Echoplex as its sonic inspiration, is distinctly dirtier and creates more nebulous undercurrents in the repeats. If you want to retain clarity in more melodic settings, it will create a warm glow around repeats at conservative levels. Push it, and it will summon thick, sometimes droning haze that makes a great backdrop for slower, simpler, and hooky psychedelic riffs.
In clean applications, this decay and tone profile lend the tape setting a spooky, foggy aura that suggests the cold vastness of outer space. The analog voice often displays an authentic BBD clickiness in clean repeats thatās sweet for underscoring rhythmic patterns, while the digital voiceās pronounced regularity adds a clockwork quality that supports more up-tempo, driving, electronic rhythms.
The Verdict
Silosā combination of features seems like a very obvious and appealing one. But bringing it all together at just less than 150 bucks represents a smart, adept threading of the cost/feature needle.
