Founded by the Christian brothers, a pair of trained analog electrical engineers, and Peter Amft, who provided freelance photography in the 60s and 70s to some of the most influential musicians, Big Joe Stomp Box Company is comprised of completely true analog paying homage to the tones of seminal rock and blues musicians of the 20th century. The company is named after Big Joe Williams, an enigmatic blues guitarist known for his hand-modified nine-string guitar and penchant for tinkering with his instruments.

The Wah-Wah features a three-position character switch toggling between Classic, British, and "Big Joe" settings spanning a range of classic rock and blues wah sounds.
