first VCO created by Robert Moog
The 901-B OSCILLATOR is the first VCO created by Robert Moog for the modular synthesizers. It's the powerful sounding you can hear on the Tangerine Dream, Klaus schulze and other electronic bands records from the seventies.
The Mos-lab design is the same than the R.A Moog design from 1968.
