So I have a Fender jazz bass (MIM) maple fretboard bass neck waiting to arrive and I contacted Consumer Relations to ask if the holes for mounting screws were pre-drilled. They said the ones for the tuning machines are but the rep said he wasn't sure about the string tree. In the event that it is not pre-drilled: Where should this string tree hole go on the headstock? What drill bit do I need? Do I NEED to use a power drill? How deep do I have to drill into the headstock?
