I really liked the whole idea of the Converse All-Wah, because not only was it aesthetically pleasing, but it also seems much more useful for the guitar player. With the wah-wah integrated into the shoe, the guitar player has much more control over the sound he/she is creating and has more mobility, as they are not planted to the spot with the wah-wah pedal. I was wondering how long the flex sensor lasted and how far the shoe could bend without the flex sensor breaking. If the shoe becomes ineffective after a while, would you have to replace the whole shoe or can you just replace the flex sensor easily?
