Beetronics Swarm
Beetronics · pedal
The Beetronics Swarm is an analog fuzz harmonizer handmade in Portland, Oregon that converts the guitar signal into a brutal square wave, then layers analog harmonies one interval above, below, or both simultaneously. Extreme frequency modulation warps and swoops the pitched harmonics in ways that soar, whine, and whoosh unpredictably. Designed for experimental rock, noise, and psychedelic players, it sits at the intersection of classic late-1960s fuzz and synthesizer-like pitch shifting. Thrillingly original and futuristic tones emerge from extended knob exploration. Retails around $270 and is sought by noise-rock and avant-garde guitarists looking well beyond conventional fuzz character.
