The Joyo JF-322 Wow Wah is an auto-wah pedal from Joyo. Unlike a traditional wah pedal, which you rock back and forth with your foot, an auto-wah sweeps its filter automatically in response to your playing, so the effect follows your attack and phrasing on its own. Joyo describes the Wow Wah as "an auto-wah with a wide range of sounds" and says "It's extremely dynamic," meaning the filter reacts strongly to how hard or softly you pick1.
What it does
An auto-wah, sometimes called an envelope filter, listens to the level of your signal and opens a resonant filter in proportion to it. Play harder and the sweep is more pronounced; play softly and the effect recedes. That makes it a hands-free alternative to a treadle wah, and a natural fit for funk rhythm playing and clean lead lines.
The Wow Wah gives you four controls to shape that response1:
| Control | What it does |
|---|---|
| Sensitivity | Sets how strongly your picking triggers the filter sweep |
| Bias | Positions the sweep, letting you tune where the effect sits |
| Resonance | Sharpens or softens the filter's peak |
| Decay | Controls how long the effect holds before fading |
Joyo sums up the design intent plainly:
"With its 4 controls (Sensitivity, Bias, Resonance and Decay) you have your personal sound at your fingertips."1
The maker also publishes a sound demo video on YouTube so you can hear the pedal's range before committing board space to it1.
Joyo also makes treadle-style wah pedals, including the Joyo Classic Wah and the Joyo Multi-Mode Wah, if you prefer a foot-controlled sweep over an automatic one.
