The present invention is multi-expression control system designed to control the individual sound from one or more compact analog sound modulator systems, often called “pedals, effects or stomp boxes,” or collectively herein “effects pedals,” for guitars, basses and keyboards. It couples features that are proprietary with off-the shelf products resulting in a system that spans the distance between a third party foot pedal and third party effects pedals. The system gives a musician “hands free” control of any third party effects pedal that has manually controlled potentiometers during a live artistic performance.
