In an effort to fix an old Jack & Danny P/J bass, I ordered a GraphTech Black Tusq nut in order to eliminate tuning issues. Now, the GT-BT site suggests using 200 or 400 grit sandpaper (not a problem) to bring the nut down to proper height and length, however, I have a few questions. How do I determine the proper nut height, assuming I want a fairly low setup suited for fingerstyle and tapping (Billy Sheehan-style)? Should I default to Jerzy Drozd's setup book on that? I have a hard-copy on my desk, but I won't be back there for a few hours. The currently installed nut is half as thick as the Black Tusq. While installing the nut, is it a good idea to sand length-wise so I would thin it down to the old nut rout? Or do I try to sand it just enough get a bit of overhang, and in which direction, towards the tuners or towards the frets? Logic suggests the neck-facing side would have to be left as is to avoid detuning the entire fretboard out of intonation. If the nut slots are too thin, is using old bass strings instead of a rat-tail file (which I don't have) good enough to widen them? Thanks for the help - this is the first time I'm replacing any kind of instrument nut.
