Beetronics Swarm Fuzz Harmonizer | Royal Series

The Beetronics Swarm Fuzz Harmonizer (Royal Series) is an outrageous and inspiring effects pedal that truly sounds like a thousand killer bees descending on your signal chain. This analogue fuzz harmonizer transforms your guitar into a snarling square-wave fuzz and then multiplies and divides that frequency to generate harmonies that range from tight, musical tracking to absolute controlled chaos.

With nine selectable harmony intervals across two octaves, the Swarm gives you an enormous range of tonal possibilities. From thick octave fuzz and synth-like textures to glitchy, unstable harmonic madness, this pedal is built for adventurous players who want something totally unique.

The harmonies are shaped by two independent voices — QUEEN and DRONE — which stay one octave apart. Modulation can be applied to the harmonies using the highly interactive FLIGHT and STING controls, allowing the pedal to shift from precise harmoniser tones to a swirling, unpredictable “swarm” effect.

The Swarm is best approached instinctively: twist knobs, explore, and let the bees guide you into new sonic territory.
