Schlappi Engineering 100 Grit Black

This is a low pass filter that can be clean and tame when you want it to be, or pushed very easily into more more noisy and distorted territory. When used conventionally the lowpass has a pleasant sound to it while the resonance has a sharper bite to it than on other filters I own.

When nudged a little, by upping the input/gain/CV the range of noise and distortion that this filter can produce is pretty large and the resonance can scream. The filter can also produce distorted semi random noise when unpatched! Despite its noisy nature there are a lot of sweet spots in this filter, and it is possible to dial this in to taste.
