I'm looking to build a wah from R.G's technology of the wah (http://www.geofex.com/article_folders/wahpedl/wahped.htm) page and I think I have a layout that'll work. I'll escape the wah pot by using an LDR instead. What I don't know is if the LDR should be in light or shadow when the pedal is "up".

ldr in light low resistance, ldr in dark high resistance.

Yes, I know. What I really wanted to know is how the wah pot corresponds to the wah pedal "location".
When I push the pedal "forward", should the wiper be closer to ground or further from ground?
shadow = up.....(kicked back)
or use the darklight to have it opposite...or even adjustable... ;)
Thanks d'astro.
This oughta be pretty kewl... Not sure how you're implementing the system, but if you want ideas, I posted pics of my wah in the 1590A thread. My wood wah (in the lounge) uses a different goofy light trap, but I'm not sure if I got pics of that part yet. You making your own treadle, or using something new or gutted (question mark... Silly qwerty keyboard won't insert one).

Let's see if I can pull it off first. If all goes well this might end up on page 1000 ;D
