The pedal gurus at Beetronics FX are no strangers to the wild world of stompbox innovation. That said, we really have to hand it to them: this particular pedal chucks the rulebook right out of the window. The Zzombee crams just about every effect imaginable into its compact enclosure that Beetronics FX proudly calls a “Filtremulator,” including fuzz, swells, tremolo, cross-tremolo, filter, randomized filter, wah, LFO, overdrive, and low octave. While it houses multiple effects, the Zzombee is not a “multi-effects” pedal in the traditional sense, and each element is finely tuned for simultaneous use with the others, resulting in a pedal that simply has no sonic precedent. Featuring three levels of gain, three filter functions, and three filter types, the Zzombee provides an ocean-deep level of control, offering everything from an edge-of-breakup overdrive to an edge-of-amplifier-apocalypse fuzzy, filter-y cascading wave of sound. An instrument unto itself, the Beetronics FX Zzombee catapults the stompbox format to brave new sonic heights.
