Description

Unleash the untamed power of your guitar with the Beetronics FX Swarm Fuzz Harmonizer Pedal. This is not your ordinary fuzz pedal; it's a sonic adventure that transforms your guitar signal into a square wave, then dives into the realm of harmony and modulation. With the Swarm, you can explore nine distinct intervals across two octaves using the intuitive Species knob. The Queen and Drone controls let you mix these intervals above and below your input note, opening up a universe of unique fuzz tones that defy conventional categorization.

The Swarm is equipped with Flight and Sting controls, allowing you to experiment with synth-like modulation. From smooth glissandos to robotic talkbox-style tones, these controls offer endless creative possibilities. Whether you're aiming for traditional fuzz or bold new textures, the Swarm's design ensures your notes are tracked with precision.

Crafted with Beetronics' signature vintage flair, the Swarm features a slanted enclosure and a side-mounted Master knob, adding a touch of visual sophistication to its innovative internals. Inside, a custom PCB adorned with bee-inspired art speaks to the meticulous detail and creativity that define this pedal.
