FYI for anyone using the Feiten offsets, an alternate tuning method that doesn't require offsets is to tune each string using an "E" (open high E string, 5th fret on B string, 9th fret on G string, 14th fret on D string, 5th fret on A string, open low E or 12th fret harmonic). It's laid out in detail somewhere on the Feiten website...
