i am curious about the fret leveling procedure.
its something i would like to know how to do and i wonder what tools are required.

any place to read about it, i have a few high frets on a neck i just attached to a precision body and to get the action a little lower and still be clean, a few frets need to be shortened.

what is used to determine what frets are too high, i can see a few by using the string as a straight edge, you just use a real straightedge when you have the strings off?
thanks
