How do you guys mark the location of the screws for a pickup, say a Jazz. I use the pickup itself and use a drill bit to mark the location of the screws but I am always off by a tiny bit because the pickup moves in the cavity. Looks like I really need 3 hands for that method...Is there a better method, or am I just being anal?
thanks
