… there it is! Only 30 pieces of the VCO.3 were built before a flood destroyed all the instrument’s documents in 1973. The Italian company GRS with headquarter in Florence is one of the great unknowns in synthesizer history. The VCO.3 with – guess what – 3 VCOs looks very interesting. Built-in spring reverb, tube amplifier … Too bad there is no CV/Gate. The panel labels are interesting. RUMORE seems quite suitable for “noise”, doesn’t it?
2 weeks ago a restored VCO.3 appeared in a shop in Bologna. We have received permission to publish the pictures of the instrument.
