Wah with LDR question
« on: April 11, 2012, 04:56:02 PM »

I'm looking to build a wah from R.G's technology of the wah 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".

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?

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  Grin
