Haible Krautrock Phaser /
Schulte Compact Clone
The background of the "Krautrock Phaser" in Jürgen's own words: If you listen to German records from the 1970's, you often hear a rather unique phasing that comes from a device called "Compact A Phaser" from the Berlin company "Gert Schulte Audio Elektronik". It's often referred to as "Schulte Phaser", and I have heard it being called "Krautrock Phaser", "Schulze Phaser" (because it's prominent on many early KS albums), "TD Phaser" (because of Tangerine Dream). In my opinion, this phaser has been important to the sound of these early electronic musicians almost as much as the synthesizers the used.
