I was executing the vocal mod an the low range mod from this page: http://www.stinkfoot.se/andreas/diy/mods/dunlop.htm#_modding_the_wah

And everything seems fine, minus one small issue. The pedal works fine for 2/3 of the sweep. The last third of the sweep, farthest from the switch, cuts from a wah effect to a loud "WHOOP" noise. That's all I can get there. I used a 56k resistor in the vocal mod, and a .022uF cap in the low range mod. Any ideas what could be amiss?

I don't have much experience with the inside of a wah pedal, but from looking at a schematic and the mod instructions, I don't see what could be wrong... Any chance you accidentally shorted something with some excess solder ? Did you test the values of the components ? Or maybe the pot is just turned too far and that needs adjusted ? Maybe you should just email the dude that runs that site with the mods...
