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
Wah engages under foot pressure and drops out when released. No stomping on and off.
Detail 02
The filter range sits below a guitar wah, so low notes still open up instead of thinning out.
Detail 03
Heavy enough to stay put on a bare stage floor without hook-and-loop.
Detail 04
Takes a full treadle footprint. Measure your board front to back before committing.
Detail 05
Tall pedal. Awkward inside shallow flight-case lids that close over the board.
Final check
Product questions
Straight answers to the questions shoppers most often ask about this product.
It will pass signal, but the sweep is tuned for bass frequencies. On guitar it sounds darker and less vocal than a standard Cry Baby.
No. The Q auto-return switch turns the effect off the moment you lift your foot. That is the design.
The circuit is voiced for bass, so the sweep stays in a usable range for low notes rather than sucking out the fundamental.
Roughly 3.9 inches wide by 9.8 inches deep, and 3.7 inches tall. Treadle pedals need front-to-back clearance to rock fully.
