From the post

Been fashinated by gyrator tonestacks for a while and when I saw this wah circuit by Olivier Jambois I had to give it a go. Sounds very good and powerful and it is loud! Schematic, a nice writeup and soundclips HERE.

Works equally well as a standalone bandpass filter pedal but I recommend to change Wah pot to linear taper since most of the action is at the end of the rotation.
