Scuzz is a pre-effect. It directly modifies the pitch of any Source blocks connected and rapidly modulates it via an LFO set to higher than usual ranges.
The sound can vary from messy pulsing, to metallic sounding harmonics, a little like a ring modulator.
In it’s options, ‘Power’ sets the depth of the effect, and ‘Pulverisation’ sets the rate, ranging from audible modulation, to where the rate becomes an audible frequency.
