I was thinking of putting a jazz ashtray and a neck pup cover (as well as the upper thumb rest) on my MIM jazz (blue with tort guard). The question I have is, is there an opening at the back of the bridge cover, or can you still replace a string if you break one? I love the idea of how this would look, but really would only do it if it's not going to limit string changes in the event one breaks.
Thanks!
