scallopng the frets has nothing to do with the frets mr. nirvana man, it deals with removing wood to create a llighter than air feel on the neck when you are playing crappy metal songs.
the back of the neck is full of dings and what not, remember its a poly finish so it does not wear away as easily as a laquer finish, whish is found on all fenders pre 65.
leveling the frets merely means that im shaving down the frets to and equal height so there are no low spots.
make any sense to you?
