Detail 01
Rocker treadle
You control the sweep with your foot in real time. Playing in tempo takes practice; it is a technique, not a setting.

Independent shopping perspective
Slash signature Cry Baby wah. A rocker-treadle wah for rock and funk players who want a fixed voicing rather than an adjustable one.

What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.

Detail 01
You control the sweep with your foot in real time. Playing in tempo takes practice; it is a technique, not a setting.
Detail 02
Nearly ten inches front to back. It eats an entire pedalboard row on most boards.
Detail 03
Narrow side to side, so it sits fine at the end of a row next to compact pedals.
Detail 04
Heavy for a pedal. It stays put under foot pressure but adds real weight to a gig bag.
Detail 05
The sweep is tuned to one player's sound rather than left neutral. What you hear is what you get.
Final check

Product questions
Straight answers to the questions shoppers most often ask about this product.
Most players put it early, before drive and modulation, so the filter acts on a clean signal. Placing it after drive gives a sharper, more vocal sweep. Try both.
Roughly 3.94 by 9.84 inches. The depth is the problem — it needs almost ten inches front to back, which most compact boards do not have.
Yes. Wah with muted chord work is core funk technique, and this pedal covers that alongside rock lead and rhythm playing.
It is a signature model with its own fixed voicing rather than the standard version's tuning. The pedal format and foot-controlled sweep are the same.
