The item is discontinued.

Dual analog oscillators with a 100% hand selected discrete transistor core. Each oscillator is individually sweepable between sine and sawtooth waves.

Range is sweeepable from ultrasonic down to LFO ranges. Exponential frequency modulation on each oscillator allows for intense, unique, and awesome cross modulation! Designed to be paired with theModel 156 Control Voltage processor.

Accurate recreations of the original 100 series modules. Entirely discrete transistor based analog circuitry, all OPamps (when used) are for eurorack level matching only.
