The Buchla Classic Reissue of the Dual Oscillator Model 258 is comprised of two independent voltage-controlled oscillators, each continuously tunable from 5 Hz to 20 kHz with two frequency CV inputs, waveshape CV input, and an FM input – each parameter with an offset control.
The top oscillator waveshape can be shifted from sine to saw and the bottom oscillator waveshape can be shifted from sine to square, allowing for a great range of timbre.
