I've had no experience restringing a floyd rose guitar untill earlier today when I broke my string. I had a pack of strings luckily, but all the guitarists I know say its a pain in the ass to restring it. I called guitar center and asked if they could do it, they said they dont do that, then I called some other local music shop and they said it would take a week due to "holiday season" and would cost me 25$. So instead of throwing my money away I did a search on it and found this http://www.ultimateguitarpage.com/tips/change.html

anyway I recomend it to anyone that doesnt know how to restring a floyd rose guitar
