I have one that I use with my Source Audio pedals - One Series and Sondblox 2. I use it as in the video, on my picking hand. It takes some getting sued to, but once you do, it's a way to add some unique flavor to an effect. Certain manipulations just happen more naturally than with an expression pedal.
