Yeah but your guitar isn't meant to be grounded by YOU dude! It's meant to be grounded by your guitar lead.... Otherwise, when you pick up the guitar and you act as the ground, the electricity flows through you - this means if any electrical things are incorrectly grounded (dodgy plugs, amps, etc) - you = dead. What I suggest is looking up some wiring diagrams for your pup config, www.projectguitar.com should help - Basically, you want to ground the bridge, the pups obviously, the pots and also the jack at the side - this means a ground wire should run in circuit with all these components. If you get a hum that cancels when you touch the guitar then you are still not properly grounded!
