CLYDE Standard Wah
Clyde McCoy was a big-band Trumpet Player in the '60s... not a great musician, but one famous for getting a muted "wah wah" sound. This led to Vox trying to approximate this muted trumpet sound in a pedal... hence the Vox "Clyde McCoy" wah wah circa 1967.
Jimi Hendrix and Eric Clapton both used a Vox "Clyde McCoy" model wah wah. Photos taken during the recording of "Electric Ladyland" document Jimi's as being the "signature" model, featuring Clyde McCoy's name written out script style on the bottomplate. The other type of Clyde McCoy was the "picture" version, which had Clyde's photo on the bottomplate. The "signature" model, with it's great sounding "halo" inductor, is what the Fulltone CLYDE is modeled after.
The Fulltone "CLYDE" was born from taking the best of the best of my more than 25 pc. vintage Vox wah collection, and analyzing every aspect... going so far as sacrificing a few of the vintage inductors to get it right.
