The JOYO JF-322 Wow Wah is a compact auto-wah pedal from Joyo. JOYO describes it as "an auto-wah with a wide range of sounds" and says "It's extremely dynamic."1 Unlike a conventional wah pedal with a rocking treadle, an auto-wah sweeps its filter automatically in response to how hard you pick, so the effect tracks your playing rather than your foot.
Controls
The JF-322 carries four knobs, which JOYO sums up this way: "With its 4 controls (Sensitivity, Bias, Resonance and Decay) you have your personal sound at your fingertips."1
| Control | What it sets |
|---|---|
| Sensitivity | How strongly the filter responds to your picking dynamics1 |
| Bias | The filter's position or character1 |
| Resonance | The emphasis of the swept filter peak1 |
| Decay | How the effect falls away after each note1 |
Because the response is driven by your attack, the Sensitivity control is the one to start with: it sets the threshold at which the wah effect kicks in for a given picking strength. The other three then shape the sweep itself1.
Power, bypass and size
The pedal runs on a DC 9V adapter and draws 22 mA1, which is a light load for any standard pedalboard supply. JOYO states the JF-322 has true bypass switching: "Of couse it has True Bypass!"1 With true bypass, the pedal's circuit is removed from the signal path entirely when the effect is off.
The JF-322 runs on a DC 9V adapter and draws 22 mA1. JOYO also publishes a manual for the pedal as a PDF and links a sound demo on YouTube from its product page.1
JOYO's power specification for the JF-322 is a DC 9V adapter, with no battery option listed on the product page.1
Where it sits in Joyo's wah range
Joyo also makes treadle-style compact wah pedals, the JOYO CLASSIC WAH and the JOYO MULTI-MODE WAH, which you operate with your foot like a traditional wah. The JF-322 Wow Wah is the different approach in the range: a small box with knobs that does the sweeping for you.1

Questions
Is the JOYO JF-322 true bypass?
Yes. JOYO's product page states the JF-322 Wow Wah has true bypass switching, so when the pedal is off your guitar signal passes straight through without going through the filter circuit. That matters on a pedalboard because it keeps the pedal from loading down your tone when it is not in use.
Does the JOYO Wow Wah run on a battery?
JOYO specifies power for the JF-322 as a DC 9V adapter, and the pedal draws 22 mA. The product page does not list battery operation, so plan on using a 9V adapter. A standard pedalboard supply with enough current headroom will run it.
What is the JF-322 input impedance?
JOYO lists the input impedance of the JF-322 Wow Wah at 500K Ohm, with an output impedance of 1K Ohm. That output impedance is low enough to drive the rest of a pedal chain without difficulty.
Is the JOYO JF-322 an auto-wah or a treadle wah?
It is an auto-wah. JOYO describes the Wow Wah as an auto-wah with a wide range of sounds, and instead of a rocking treadle it uses a Sensitivity control to set how the filter responds to your picking, along with Bias, Resonance and Decay controls.
What size is the JOYO JF-322?
JOYO gives the dimensions of the JF-322 as 73 mm long by 43 mm wide by 50 mm high, and the weight as 220 g. It is a compact pedal that takes up little room on a pedalboard.
