for those with a knob fetish

"The Polivoks synth is rare socialist moog like madness! The sound is fantastic rich and warm – 100% pure analog machine! It was made in period of 1982-1990 and sold in Russia (then USSR).

The Polyvox (Polivoks) is a duophonic analog synthesizer, with a 49-note (13F-E) keyboard. It features two VCOs, a noise generator, one LFO, a filter (low-pass and bandpass), and two ADSR envelope generators. VCO1 can be cross-modulated by VCO2. Each ADSR can be switched to auto-trigger, each with independent rates.The sound is quite rich and somewhat harsh and aggressive. This is more of a space-synth. You can be sure that you will have never heard the sounds this one can produce. It sounds like these old Yamaha CS-30's, but then fat filters like in Moogs. It is built like a rock, pure military technology, contacts will last forewer. The body is solid and the knobs feel nice. It runs on 220V AC. Polivoks (Polyvox) is the most popular vintage Russian synthesizer all over the world. It has inimitable peculiar sound and very powerful aggressive filters outperforming the famous Minimoog! A fat, lush and very analogue sound is achieved through instability and thanks to unique architecture of the Soviet-era components; in addition, highly reliable military technologies were applied in the process of production. The synthesizer may be used for hard electronic music, or for soft ambient/old school projects and for modelling various effects as well."
