Have you tried the bypass at stop? I use that setting and it just shuts off as soon as you stop moving your foot.
I think that´s annoying as hell ... Sometimes you want that flat out sharp "screwdriver in the ear" toe sound
for a longer time than one second , and then it just turns off .....
Same with the "off at toe or heel position" ......
I turn wah on/off with switch on my Voodoo Lab Pro
But that´s me
