Sorry for the misunderstanding. The pickups are stock, and the tape is there to prevent the screws from rusting, because I sweat a lot when I play. The tape has gotten dirty, so I'm planning to replace it.
Are you referring to the headstock modification? I secure the strings with a Floyd Rose locking nut and then add another locking nut at the string ends for protection to avoid injury. To prevent the strings from slipping, I pass them through the ball ends inside the headstock.
