mutronc200wah.png
Heres a vero layout for anyone interested. has a 1054 inverting voltage doubler to give v+ and v- at around 15v and -15v. ldr 1 and 2 are close to the led and ldr 3 is opposite, use a bit of plastic or something to block/expose ldr 3 to the led. i used an old morley wah for mine which already uses an led so are pretty easy to gut and use (and cheapish, old pro series 2).

when its off the volume is still affected when the foot-pedal is moved a bit since the volume ldr is still exposed to the led, so might be good to use a 3pdt for volume, using the extra row to bypass the ldr when the effect is off.

if theres a volume drop when the wah effect is on try lowering the value of the 22k resistor connecting the first two op amp stages. or even better, use a trim pot around 25k until the signals match.
