This is a dual resonant filter and preamp pedal. It features high-pass and low-pass resonant filters, inspired by classic synth circuits like the Korg MS-20.
It’s used to shape your guitar or bass signal dramatically. The resonant filters can create sweeping, vocal, or synth-like "wah" effects, and the preamp adds warmth and drive.
Great for guitarists, bassists, or synth players who want precise control over frequency sweeps, deep filter effects, or just a unique tone-shaping tool.
