The Justin Chancellor Cry Baby Wah is a multi-tool of sonic craftsmanship, combining three separate effects into a single pedal: the fluid expressiveness of a custom midrange filter, the bright aggression of a custom wah circuit, and the chainsaw grind of a vintage fuzz.

It's the perfect complement to bass player Justin Chancellor's multi-dimensional role in the band Tool. Whether opening up soundscapes with chords and harmonics or syncing up with guitarist Adam Jones to perform arresting single-note unison runs, Justin goes above and beyond the traditional boundaries of his instrument to help compose the band's multi-layered tunes. He is, without a doubt, one of the modern pioneer users of effects on bass, and he keeps a carefully configured pedalboard at his disposal for crafting tones and exploring sounds. This custom Cry Baby Wah combines some of his favorite ways to do just that—filter, wah, and fuzz.
