Rat Distortion

From the circuit: a slow op-amp with huge gain (its two ground legs set where the gain starts, and its bandwidth shrinks as the gain grows, which darkens and thickens it), into a 1k resistor and two silicon diodes to ground, worked out from the diode equation and antialiased at twice the rate, then the famous Filter knob: turn it up for a darker, smoother sound. From crunchy rhythm to a buzzing wall.
