I'm happy to share Krautrock Phaser, the latest release from End of the World Plugins. It's a stereo phaser inspired by the Schulte Compact Phasing "A" (ca. 1973, West Berlin), the unit used by Kraftwerk, Tangerine Dream, Klaus Schulze, Conny Plank and others. It is so closely associated with the kosmische and Krautrock movements that it became known simply as the "Krautrock Phaser."

How it works:
Eight first-order all-pass sections share a single LFO, producing four evenly-spaced notches that sweep together through the frequency spectrum... dense and harmonically rich, more like sound moving through physical space than a filter sweep. Feedback is tapped after stage 2, creating the tight, resonant low-end bite that gives the Schulte its characteristic voice.
The lamp model gives the sweep a slightly lopsided, breathing quality. It rises faster than it falls, the way a real incandescent bulb responds to current. The Bias control determines how deep the sweep travels: lower values open it up into a wide, dramatic arc; higher values pull it back into something subtler and more continuous.
Two stereo modes:
* Hardware — shared LFO across both channels, faithful to the original character
* Dual LFO — independent LFOs offset 180°, for a wider, more animated stereo sweep
