im trying to on my strat to put a black one on, should I do it?
just don't strip the screws
sure, but you need to get a bunch of stuff done about the electronics hanging of of it.
Well first off, you must take out the screws on the pickguard. Make sure not to tamper with the screws near the pickups, for those are the height-adjustment screws. Wait until you have the pickguard off to unscrew these. I assume you're putting all the original electronics in it as well? I would just keep everything soldered and take it out in one piece. To remove these parts from the pickguard, just take the knobs and pickups off their specific mounts. Now just go backwards for your black guard.
dont forget to de-solder the wires from the input jack
