The Dunlop Cry Baby is a popular wah-wah pedal, manufactured by Dunlop Manufacturing, Inc. The name Cry Baby was from the original pedal from which it was copied, the Thomas Organ/Vox Cry Baby wah-wah, first manufactured in 1966. Thomas Organ/Vox failed to register the name as a trademark, leaving it open for Dunlop. More recently, Dunlop manufactured the Vox pedals under licence, although this is no longer the case.

An effects unit, effects processor, or effects pedal is an electronic device that alters the sound of a musical instrument or other audio source through audio signal processing.
A pedalboard allows a performer to create a ready-to-use chain of multiple pedals to achieve certain types of sounds. Signal chain order: tuner, compressor, octave generator, wah-wah pedal, overdrive, distortion, fuzz, EQ and tremolo.
