I am selling my Erica Synths Black VCO. It has signs of rack rash at the screw holes, but that does not impact functionality in any way.

Erica Black VCO is analogue VCO with four simultaneous waveform outputs and one octave down suboscillator. The core of the VCO is borrowed from famous Russian synth Polivoks VCO and in exponential converter we use the original matched transistor IC that was used in Polivoks. Unlike harsh logic divider based suboscillators, Black VCO transistor-based suboscillator generates distinct, rounded squarewave.

FEATURES: Simultaneous sine, triangle, saw and pulse wave outputs -1 octave suboscillator

Manually adjustable and CV controlled pulse width

Great tracking across 8 octaves

Exponential FM input with attenuator

Synchronization input

Octave switch – 5 octaves
