New from the, er, hive mind of Californian effects firm Beetronics comes the Zzombee Filtremulator – an analog multi-effect pedal that combines four gain stages and three modulated filter modes with unique and musical results.

Those aforementioned four gain stages are designed to run in parallel with a low octave circuit and you can then apply the filter to one or both of these elements. As such, you can expect sounds that blur the worlds between filter, wah, LFO, tremolo, fuzz, overdrive and octave effects. The resulting build looks (and sounds) impressive.
