The Black K-Phaser by Erica Synths is an analog phaser effect with built-in LFO is reminiscent of the wedding of Krautrock and Tangerine Dream. The circuit, implemented with photoresistors, has eight stages, which allows for a very dense sound and at higher resonance also brings out vocal-like. For more variation, a toggle switch selects between Classic and Spread Mode. The LFO has the waveforms triangle and ramp, can be controlled in speed and has its own CV output to be able to modulate other module as well. If you plug a patch cable into the CV-In socket, the LFO is disconnected from the Phase parameter and the external signal can affect phase with positive or negative deflection.
