Expression Pedals

An expression pedal converts foot movement into a control signal rather than processing audio directly. It can sweep parameters such as delay time, modulation depth, pitch or volume on compatible equipment. Potentiometer value, wiring polarity, connector type and minimum-range controls must match the receiving device; some models provide multiple outputs or programmable MIDI control instead of a passive resistance.
