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, than multiplies and divides the frequency of that wave, giving you nine 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.
