I have a Morley Bad Horsie wah. I love the fact that there is no on/off button on it. As soon as you take your foot off of it, the wah is disabled. This is great for hitting the wah quickly for a quick change in sound or to add some brightness to a harmonic. I've heard this pedal is a known tone sucker, so I've been looking to replace it, but I can't find a high quality wah that behaves in the same way. Does anyone know of another good wah pedal with this functionality?
