it depends on the tuning methods available to you..... i would say use a chromatic tuner, if you don't have one you could use a variation of the 5th fret tuning by doing this......

start w/ standard tuning.... then....

tune E to A at the 8th fret (to C#)
tune A to D at the 6th fret (to G#)
tune D to G at the 6th fret (to C#)

then......

tune G to D at the 5th fret (F#)

i would use open tuning for the high C# and tune the 5th string to the middle C# you already have tuned

and the same for the high F#, raise it to F# by tuning it with the 4th string

this is how i would tune it by ear.......

any other suggestions?
