A few weeks? :eek:

This should not take very long. After you are strung up, stretch the strings manually. Some people pull on them like a suitcase handle, but I have broken strings that way. I prefer to do some heavy bending around the 12th fret on all strings. Just drive each string up a couple of steps, retune, repeat. Should get pretty stable right away (aside from the joy of tuning the Floyd each time).
