The Clyde Standard Wah from Fulltone is based on the classic Vox "Clyde McCoy" wah, used by both Hendrix and Clapton. The inductor is a tuned core hand-made unit that uses the exact same type of wire and inductance as the '60's Vox wahs, but with an internal "resonance control" for bass and gain adjustment. Fulltone also has their very own "Fullrange" pot that give the wah a much wider range of response. Also utilizing a booster/buffer that gives up to a 20db clean boost making this wah much more "fuzz friendly."
