The CLYDE Standard Wah by Fulltone is modeled after the Vox Clyde McCoy, used by Jimi Hendrix and Eric Clapton. Jimi used the Clyde McCoy while recording Electric Ladyland! Clyde McCoy was a big-band Trumpet Player in the '60s. He wasn't the best but became famous for getting a muted wah wah sound. Vox tried to approximate this muted trumpet sound in a guitar pedal... hence the Vox Clyde McCoy wah wah circa 1967.
The Fulltone CLYDE was born from taking the best of the best of a more than 25 piece vintage Vox wah collection, and analyzing every aspect... going so far as sacrificing a few of the vintage inductors to get it right.
Fulltone's Inductor is a tuned core hand-made unit using EXACTLY the same type wire and inductance as the '60's era Vox, except VERY consistent from one unit to the next. A tuned core inductor is much more expensive to make, but the end result is worth it, drop this into your wah and Experience the difference! The only change from the original '60's Vox design is the addition of a very usable internal Resonance Control which is a large durable trimmer, for Bass and gain adjustment, which is easily adjustable by hand without tools and with room to mark your favorite settings.
