The name of this part pretty much says it all! This is the Proto Pedal Enclosure, a custom-machined aluminum case designed specifically for the SparkFun Proto Pedal. This enclosure was designed to take a beating even under the hardest jam sessions. Paint it, sand it, or do whatever you want with it -- the Proto Pedal Enclosure can take it. Go ahead, step on it too hard with ROCK POWER!
