I am kickstarting a new type of Expression pedal. Please check it out and let me know what you think. It all started because I had pedals with expression input, but since most expression pedals behave like a wah, it just makes your pedal act like a wah. As more and more pedals include expression input, I think there is a real opportunity to get creative with expression pedal design. Also I liked the idea of an expression pedal with the footprint of a standard pedal.
I have also been a big fan of Arduino for years and I wish to help open that door for pedal modders. This expression pedal has an entire Arduino inside of it that can be programmed using the Arduino programming language. So the behavior of this pedal is only limited by your imagination.
