Here's a cool auto wah from Robert Penfold that can sound really funky and bubbly. In the soundclip the resonance and depth are maxed. I have adapted it for true bypass and added a volume pot since the output was alittle bit above unity. The controls are a bit finicky, especially the frequency controls that goes from low (so low that it kills the signal) to above the hearing range. I think a log pot work better here. I used a 2M resistor insted of the 1.8M and a BC108B transistor with good results. The 10K trimpot sets the input for the envelope follower. Adjust it until it sounds good and you get a "natural" sounding release.

From the volume pot, middle lug (lug 2), as written in the notes.
