SWARM (Fuzz Harmonizer)


The Swarm is an Analog Fuzz Harmonizer that sounds like a thousand killer bees coming to get you!

It basically turns your input signal into a square wave, then multiplies and divides the frequency of that wave, giving you 9 possible harmonies in two different octaves. Modulation is applied to the harmonies making them go from a nearly perfect tracking harmony, to a wild and uncontrollable swarm of mad bees. The Swarm is best when played by instinct. Mess with every control until you find a tone that you like and let the bees take you to sonic places you've never been!
