PolyRhythm is a dual analog filter + phaser box. It has two voltage controlled filters and a low-frequency oscillator made from authentic Soviet components. It has 8 knobs, 5 switches with which you can control the parameters of the sound. Both filters are made of components and circuitry in accordance with well-known Soviet synthesizers, produced in USSR back in the 80's and 90's.
