The Meat Sphere is an envelope filter pedal which is based on a popular boutique filter pedal. That pedal was itself based on the old Mutron III filter, and all of these are examples of the "state-variable filter" (SVF) topology, which can produce highpass, lowpass, and bandpass filter outputs from a single circuit.
