I got Rocksmith as a gift a few months ago, and I immediately loved the game. The only problem that I found was that it required a controller for navigation. This was awkward for a few reasons. I disliked having to pick up and put down the controller to do every little thing in the game, like pause, restart, and especially to select my pedal presets. Guitarists use stompboxes and pedals to control their effects with their feet, which leaves their hands free to play the guitar. This controller is an attempt to copy that funtionality. You can select preset pedal effects in the game by pressing X,Y,or B during a song (the A button resets the pedal to the song's original pedal). This is a cool feature. Cool, but hard to negotiate while trying to play guitar. I tried to see if there were any premade solutions out there. There were none that I could find.
I started planning.
