Dueling at the FX Frontier
StarskyCarr opens with the tantalizing promise of taking on Behringer’s most recent contender, the BM-18M Clusterbox, against Moog’s revered MF-108M Clusterflux. Straight out of the gate, it’s clear we’re in for a gritty showdown between a newcomer with aspirations and a well-loved classic. As Carr sets the stage, he highlights the key similarities: emphasis on chorus and flange effects, CV modulation prowess, and stereo capabilities. These two are like battling guitarists in a punk band, each straining to outdo the other in tonal richness and versatility. Expect flanges sharp enough to slice through the toughest of mixes and choruses that could widen the grin on a Cheshire cat. A myriad of modulation options await those brave enough to dive in, making it clear why both these units have their place in the world of sonic exploration.

Diving headlong into the chorus capabilities, Carr navigates us through a journey that’s as exhilarating as it is comprehensive. The Behringer and Moog duel it out with charisma, pushing each other to explore the lush depths and sparkling highs of their modulation realms. What stands out, according to Carr, are the nuances in stereo imaging—the Moog is a silky beast, phasing like a dream, while the Behringer offers more raw force. Like two boxers in a ring, one is smooth and calculated, the other a bit raw but bursting with untamed energy. Carr brings forth the juicy details of each oscillator’s behaviour and sweeps through rate and feedback settings with the precision of a DJ spinning their wildest set. Through Carr’s perspective, we see where each machine shines and where they stumble, revealing the delightful quirks that could either break or make your final decision.
Flange Finesse and Feedback Artistry
Carr then flips the switch to flange, aiming to showcase how each unit fares under pressure. With his seasoned ear, he dissects the warmth and punch of the Clusterflux’s flanger, finding it impeccably suited for those seeking an elegant yet powerful effect. The Behringer, however, doesn’t tread quietly—it comes roaring in with aggressive overtones. Like a bar brawl where chairs fly, the Behringer refuses to hold back, offering a surge of intensity and grit. Carr crafts a vivid auditory scene where each device’s strengths and peculiarities shine with crystal clarity. He digs into feedback paths and CV routing with fervour, illustrating how these features open an array of creative possibilities for the daring synthesist.

The Devil in the Details: Clicks and Quirks
StarskyCarr unearths the quirks that could tip the scales in either direction. The Clusterbox, though valiant, displays a few unsightly clicks and noises that may remind one too much of a public address system on its last legs. The seasoned pro, however, who knows their way around a Moog, finds solace in the reliability of the Moogerfooger. Carr compares the distortion levels and headroom, finding the Behringer somewhat rough around the edges—a bit like a punk guitarist who’s yet to find their balance. Exploring various settings, he notes where each unit stands strong and where each could falter. As he tweaks each knob and dials each setting, the video becomes a master class in understanding the impact of every modulation choice on these devices.

As the video draws to a close, StarskyCarr reflects on whether the Behringer can truly match the Moog legend. While the price difference might entice the thrifty, those seeking perfection might lean towards the classic. The Clusterbox’s quirks might charm those who crave a bit of unpredictability, but its limitations are palpable when stacked against the polished finish of the Clusterflux. Carr leaves us with a cheeky nod to the unpredictable nature of these units, inviting viewers to take his insights to heart as they decide which flavour tickles their creative fancy. Typical of Carr’s style, his conclusion is candid, reflecting a genuine passion for uncovering the raw truths nestled within every knob and circuit.
