G-Lab True Bypass Wah-Pad User Manual page 9

To eliminate movement of the wah-wah effect over the pad, you should stick
movement limiters (adhesive elements supplied inside the package) on the upper
surface of the pad's plate (close to the wah-wah effect legs – as shown on the picture).
To fix the wah-wah effect we suggest to unscrew the legs and use the industrial
velcro.
