Dual Oscillator Model 258

The reissued Model 258 sees the classic Buchla oscillator return with its precise voltage-controlled circuitry and continuously variable waveshape. Each independent oscillator has complete CV control of waveshape and frequency with offset controls, plus frequency modulation input, and premium, oversized knob caps for accurate hands-on adjustment.

Features:

• Two independent VCOs, tunable from 5 Hz to 20 kHz
• Waveshape control for continuous variation from sine to saw (top oscillator) and sine to square (bottom oscillator)
• Frequency and Waveshape CV inputs with offset
• Frequency Modulation input with attenuator
• Fine-tuning frequency pot
• Three outputs per oscillator
