This is basically what's inside a stompbox, in case you didn't know before:
Obviously a snipped wire would be a problem, but cased inside metal like that, that's almost never a problem. Problems with SB's lit in the connections and small parts soldered into the boards. Both of which can be fixed with a short trip to a small electronics store that carries said small parts and a soldering iron. Long as you know what you're doing.
Plenty of people actually make their own stompboxes or mod current ones to better suit themselves, because if you understand the physics/technology, it's not that hard to do.
G'night!
