Momentary switch for a wah?

[Chris S]

Just wondering if anyone has ever built a wah with a momentary switch, that engages once you have weight on the pedal. It's probably the only pedal you use only when your foot is actually on it. I'm sure there are some reasons went its not a good idea just wondering if anyone had tried it. Thanks.

Several locals here have put the momentary in the treadle so it's "auto on" when stepped on. I've never seen/heard of any issues.
