A noob here. On my POD HD's Settings page#2, I found the FBV Express setting and turned it on, but none of the preset tones with Wah pedals in their chain are affected (i.e., they don't make a wah sound) when I rock the pedal. I made sure to press hard on the toe switch to turn the pedal to Wah instead of volume. Is there something I'm missing? Thanks to anyone who might be able to help.
