How hard is this? I'm sure theres other names for it, but I'm thinking just a spring loaded little round button, when you push it in the signal is cut off, when you release it the signal returns. I think tom morello of rage has something like this(granted on guitar)? Anyway, I've never done any modding so I'd have to get this done at a shop....how much should it run me? I'd attempt it myself but I dont have any soldering skills/tools.
