8HP Multi-Mode LP/BP/HP Sallen-Key Filter with Tube Saturation & Distortion 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. Width: 8HP Depth: 30mm Tube Height from panel: 40mm Power: 230mA @ +12V / 70mA @ -12V
