Zlob SVF Pingable Filter Module

Zlob SVF Pingable Filter Module

The Zlob Modular SVF is a compact 4HP 2-pole 12dB state variable filter for Eurorack systems, offering low pass, band pass, and high pass outputs in a small but flexible format. Inspired by WASP and Thomas Henry filter topologies, it is designed for everything from clean filtering and classic subtractive synthesis to resonant sweeps, pinged plucks, and chaotic self-oscillation.

The module includes two audio inputs, with the second input jumper-selectable for standard audio input or pingable operation. Dedicated CV inputs let you modulate cutoff frequency, including an attenuverted ACV input for more controlled movement. Jumper-selectable resonance modes allow the SVF to move from clean and precise to juicy, drippy, low-pass-gate-like plonks, screaming resonance, and self-oscillating sine-like tones.
