Vox Clyde McCoy Wah Clone
A wah-wah pedal (or just wah pedal) is a type of guitar effects pedal that alters the tone of the signal to create a distinctive effect, intended to mimic the human voice. The pedal sweeps the peak response of a filter up and down in frequency to create the sound (spectral glide), also known as "the wah effect." (Wikipedia)
I built a clone of the original Vox Clyde McCoy pedal for a friend. I used a number of off the shelf components as well as several high end components which are a bit hard to find. This includes components such as the "yellow fasel" inductor. Overall, the final product turned out very well.
Here's the circuit diagram for the device:
And a few pictures of the board and the internals:
