VAMP is a multi-mode analogue filter that gives you low-pass, band-pass, and high-pass responses in a compact 8HP design. At its heart lies a classic Sallen-Key topology supercharged with real vacuum tube (12AU7) saturation and multiple stages of clipping, letting you move seamlessly from smooth, hi-fi filtering to snarling, overdriven character.
One half of the tube is used to saturate the input, while the other half powers the resonance feedback path with an MS-20-style clipping stage. Combined with assignable VCA placement (pre- or post-filter) and a dedicated output clipping circuit, VAMP delivers everything from subtle warmth to ferocious harmonic destruction.
Features
- Three filter modes: low-pass, band-pass, and high-pass
- Classic Sallen-Key topology with tube saturation and clipping

- Integrated VCA switchable pre- or post-filter via Flow toggle
- Three-way output clipping: off / soft clipping / hard clipping
- 1V/Oct tracking: use VAMP as a VCO in self-oscillation
- Extensive CV control: VCA gain, frequency modulation (FM), and resonance (Q)
- Self-oscillation for screaming acid tones
