Analog suboctave divider circuit
A unique analog suboctave divider circuit, used in the Soviet "LIDER" guitar floor effects unit. This design is different from most octave effects because the divided signal has a strong resemblance to the input, instead of a square wave. A wet/dry mix control and a stability filter have been added for modular convenience and deviant audio behavior.
