I use a visual technique...
I tune it and to get the sound perfect I keep hitting the string while adjusting till the next string in line starts vibrating, the vibrations are visible btw they should happen at the exact same moment you strike the string you're tuning to.. I believe when that happens you have found the resonant frequency (exact same) frequency of the note you're trying to tune to..
it's still using the 5,5,5,5,4,5 fretboard tuning style... ^_^
