Beetronics Whoctahell Custom Geometrico
Beetronics · pedal
The Beetronics WhoctaHell is the inverse of the OctaHive: rather than adding an octave above the played note it generates one below, combining overdrive and fuzz with a squared-wave sub-octave that resembles an eight-bit bass synthesiser. That gnarly, synthetic low end is the pedal's signature and puts it closer to a synth-fuzz than a conventional octave pedal. This Custom Geometrico edition carries hand-painted geometric enclosure artwork, produced in a small individually finished run, and sits in a slanted pedalboard-friendly enclosure. It suits players after aggressive sub-octave textures rather than classic octave-up fuzz.
What stands out
“Most praised for the synthetic character of the low octave”

— from the community notes
“experimental and doom-adjacent material as much as lead work”
