The Dunlop Cry Baby 535Q multi-wah is a highly versatile wah pedal that expands on the classic Cry Baby design with extensive tone-shaping controls. Instead of a single sweep, it features a six-position Range Selector to choose different wah frequency centers, and a Variable Q control to adjust the filter’s width from narrow and sharp to broad and smooth—letting you dial in everything from classic funk to expressive rock wah sounds. It also includes a switchable boost circuit for up to around +16–18 dB of gain to help your wah parts cut through the mix. These features make it something of a “Swiss Army knife” of wah pedals for guitarists who want more control and flexibility than a standard wah.
