Synther-2000
The FBT Electronica Synther-2000 is a rare Italian monophonic analog synthesizer from 1973, featuring three VCOs with sawtooth and square waveforms, subtractive filtering, and a unique continuous oscillator frequency slider that produces Theremin-like effects. It was the first synthesizer from FBT Electronica S.P.A., a company founded in 1963 that had primarily focused on amplifiers and mixing consoles.
