Even though there are a dozen better and easier ways to do a similar thing, I love the idea of Miss Parker, a Belgian open-source digital stompbox. They've built a box containing the same DSP chip that's in an Alesis Ion. The idea is that you download a patch and turn the box into a phaser pedal. Get bored of that, and you can turn it into a moog filter. Obviously all the knobs can be programmed to do anything you like. So far they’ve built just five prototypes, and no word yet on if they'll ever be commercialised.
