Dunlop Cry Baby

The Dunlop Cry Baby is a 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.

The said wah-wah effect was originally intended to imitate the supposed crying tone that a muted trumpet produced, but became an expressive tool in its own way. It is used when a guitarist is soloing, or to create a "wacka-wacka" funk styled rhythm. The original pedals were popularized by guitarists such as Jimi Hendrix, Eric Clapton, and David Gilmour, although many artists have developed signature sounds with them since.
