The 3 Series Bitcrusher was built from scratch to do two things with precision: reduce bit depth and reduce sample rate, with a filter to shape the result. The Crush knob controls bit depth, moving from full 24-bit resolution counterclockwise down to 1-bit clockwise,from unprocessed through grainy and textured, into square-wave aggression and gated digital distortion. The Sample Rate knob works counterclockwise from a clean 32.768 kHz down to 2.5 Hz, introducing aliasing and artifacts that range from subtle harmonic shifts to metallic, ring-mod-like chaos and full digital collapse. The Filter knob shapes both, fully clockwise is unfiltered. Turn counterclockwise to sweep the corner frequency and increase the filtering. The Type toggle selects the filter character: down is a second-order low-pass with no resonant peak, inspired by vintage synthesizers like Oberheim, full-bodied and well-suited to bass guitar. Toggle up is a high-pass and low-pass swept in succession, focusing a band of strong mid-range frequencies that evokes the small speaker sound of a handheld game console. Under the hood, this pedal applies a zero-hole filter,a theoretical signal processing concept that had never found a practical application until it became part of this circuit.
