On a new out of the box bass there seesm to be a thin plastic film over the pickguard. There were two pinholes and I picked at one to see what it was and made the hole bigger and so now it's not so pristine. Are these protective films and meant to be removed or just stay on for more protection? It would seem to be a bit of a problem to remove with all the screws that seem to have been placed through the film. Is it better to remove now or later or not at all?
