Photocel

Light that throbs and pulls.

Lopsided, throbbing four-stage phase shifter swept by a lamp and light cell: chorus mode for liquid, pulsing notches, vibrato mode for a seasick pitch wobble.

How it is made

Original sOURnd design blending general techniques: four first-order all-pass stages at widely staggered break frequencies, an LFO-driven lamp followed by an asymmetric one-pole light-cell model, exponential frequency mapping, and a chorus/vibrato blend of dry and phase-shifted signal.
