Thanks- I haven't had time to start taking it apart yet. I really want to keep the covers on. Only going to swap out the bridge pup. I'm happy with the stock neck (and middle position sounds).Wait, I see what you're saying, you already have S2 pickup covers and you want to use them with SD pickups. F-spaced wouldn't fit, but the standard I'm not sure. S2 pickups are 50mm and I believe SD is 49mm.
