(TeamRock Radio) A creative design agency have developed a Converse All Star shoe with a built-in guitar wah wah pedal. Critical Mass developed new technology that allowed them to built the effects pedal into the sole of a Converse Chuck Taylor sneaker and they've named it after Chet Atkins - the guitarist who pioneered use of the wah wah pedal.

Staff at Critical Mass say: "We wanted to make Chucks even more rock'n'roll. So we thought, why not turn one into a wah wah pedal? Having the idea was the easy part, the difficult part was learning to make it.

"The amount a wah wah pedal moves up and down is measured by something called a potentiometer. In order to allow the Converse, as it flexes, to act as a wah wah pedal, we needed to replace the potentiometer with something called a flex sensor." Read more and check out a video here.
