"The push.pull pedal is a synth effect based upon the PLL (Phase Locked Loop) IC, in which the PLL has been “unlocked” and let loose through 16 knobs, a joystick, switches, and a light controlled filter. It is hard to describe the sounds I have already heard: distorted, glitchy, fuzz, bass synth, drone, full of clicks, 8 bit, and erratic synthetic hyperdrive.
