Used on "Phantom Limb", as featured in this May 5, 2019 interview on the website for Stompbox: 100 Pedals of the World’s Greatest Guitarists.

“This is another great Dr. No pedal, the Road Runner,” Van Leeuwen states. “It’s a great-sounding wah with an octave fuzz, and in a very nice package. It has the fuzzy surface on it like those old Foxx pedals, too. It just does its thing. I used it on the song ‘Phantom Limb’ by Gone is Gone.”
