The Black K-Phaser retains the original concept of 8 all-pass filters with photoresistors, but we redesigned the filters and modulation circuit and added several unique features. A dip switch allows for selecting the number of filter stages involved in the resonance path, while the resonance attenuverter brings in never-heard-before feedback artefacts, and most importantly – the SPREAD mode detunes the all-pass filters for even more distinct behavior. A built-in voltage controlled LFO with selectable waveforms expands the modulation possibilities of the phaser and can be used as an independent modulation source for your modular system as well. 

The Black K-Phaser is our tribute to the German electronic music pioneers that largely shaped the sound of electronic music worldwide.
