I am working on a 1971 Precision Bass, I am a guitar guy for the most part but I do a lot of wiring and setups, and also wiring in amps. my question is about setting frets. almost all of the frets on this bass are puling out of the fretboard. do I need to completely pull them out and re-set them or just press them back in. I have acess to all the tools necessary and I intend on practicing on a few less valuable instruments before I start on this one.
