Are you sure you're turning the wah off? It sounds to me like you might not have the off/on functionality of the wah assigned to the expression pedal toe switch. So when you click the switch, you're changing the function of the expression pedal from EXP1 to EXP2 or vice versa, but you're not actually turning the wah effect off. To remedy this, go to the switch assignment screen, go to the wah effect, and select the expression toe switch to control the wah effect.

Just want to say that I've encountered the scenario as Phil_m describes.
When you put the Wah in the chain it is "on" by default and likes to stay on even if you try to setup the Exp pedal... you must do it exactly correct.
This video (starting @ the 3:30 mark) helped me understand how to set it up and I've bookmarked it for reference when I forget.

Thanks! I'm still struggling to understand the finer points of footswitch and pedal mapping (as you can tell). The wah is fine now.

Just a thought...You could be hearing the realistic tone suck the stock wahs have...
If the InputZ parameter is set to AUTO and the wah is first in the chain, then the input impedance will drop just like it does on a stock pedal...To remedy this, set Input Z to 1M or 3M...This is on the input configuration menu and can set set per patch...This switched impedance is actually not modeled, it is analog and only on input 1 of the HD500...input 2 is not affected by input Z and is a 1M input as I recall...

Agreed. That was my first thought, but the change in tone was more profound than you'd expect from a lowered input impedance. Turns out to be my misunderstanding of the toe-switch assignment (thought it was automatic).
