Jim Dunlop Justin Chancellor Signature Crybaby Wah Pedal

Justin Chancellor's signature Cry Baby Wah pedal represents a groundbreaking fusion of three distinct effects circuits, engineered specifically to match the multi-dimensional sonic requirements of Tool's legendary bassist. This innovative pedal combines a custom midrange filter, aggressive wah circuit, and vintage-inspired fuzz into a single, comprehensive tone-shaping tool. Chancellor's pioneering approach to bass effects has redefined the instrument's role in modern progressive rock, moving far beyond traditional boundaries to create the complex, layered soundscapes that define Tool's distinctive sound.

The pedal offers two primary modes: U.K. Filter and Wah, each providing dramatically different tonal characteristics. The U.K. Filter mode utilises custom solid-state circuitry that emulates the envelope-like filtering of Chancellor's bass tone control, producing thick, throaty sounds with pronounced peaks—perfectly capturing his melodic phrasing heard on tracks like "The Patient." The traditional Wah mode employs the classic red Fasel® Inductor with modified Cry Baby circuitry for more aggressive tones and rich harmonics. Both modes can be customised using separate Volume and Q controls, with seamless switching via the dedicated Wah Select footswitch.

The integrated fuzz circuit, based on a ferocious vintage UK design, cuts through dense mixes while maintaining the thunderous low-end presence essential for bass guitar. This fuzz provides the harmonic content that Chancellor relies on for his crushing yet musical passages, as demonstrated on Tool's "Jambi." By default, the fuzz activates only when using the rocker pedal, though it can be engaged independently via a side switch. The pedal's custom circuitry maintains low-end thickness by boosting the clean signal at 400Hz and blending it with the effect signal throughout the rocker's sweep, ensuring your bass retains its fundamental power while adding expressive tonal variations.
