Guitar wah pedal?
Question, I would like to build a simple wah circuit, and i looked in Tonepad.com and it gave one result but the circuit was a distortion pedal, it was weird, but anyways, ive heard that wah's are easy to build the circuit but the build is hard, the pedal part. sooo any circuits anyone knows of? thank you!!!

By far the most common wah circuit is one based on the original Vox/Thomas Organ wah--which eventually was picked up by everyone and eventually became the Crybaby (currently owned by Dunlop). Here's a PDF with some variations.
Most wahs are very similar, mostly because the classic circuit is an LCR filter (which utilizes an inductor) and has resonance--and that sounds good with guitar.
There are other circuit types such as the "Twin-T" variable filter that don't need an inductor. They aren't quite as popular.

There are LOADS of wahwah circuits on line from optical coupled devices to traditional Pots.
