The Perpetual Falsehood is a combo tremolo and phase shifter pedal with vactrols and LED lights. It offers a variety of tonal options, including classic tremolo, tremolo with a wah filter, and different wave shapes. The controls include output volume, tremolo depth and speed, wave shape toggle, filter tone toggle, filter circuit toggle, and wave shape toggle. The circuit design uses pots that act as cuts rather than increases in value.
