apollo view vamp price : $369.00

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 provide ms-20-inspired resonance limiting (tube, not diodes). with flow placing the vca pre-tube or post-filter, and fangs selecting off / soft / hard output clipping, vamp ranges 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
12au7 vacuum tube: one half for input drive, one half for resonance distortion
ms-20-style resonance limiting/clipping for aggressive tones
flow switch: integrated vca pre-tube or post-filter
fangs: output clipping: off / soft clipping / hard clipping
1v/oct cutoff tracking: use vamp as a vco in self-oscillation
extensive cv control: gain, freak (cutoff), rez (resonance) (all with attenuverters)
self-oscillation for screaming tones
