loosened all the strings then tightened the screws
in a back a couple turns( evenly each side ) then
put the bridge in place and tightened the strings
n made sure the bridge didnt come up as i did so.
when i had the strings tuned i loosened the screws
a bit n retuned then loosened the screws and retuned til i got em back where they were.there was a thread in here a couple weeks ago ( forget where) bout floyd rose.guys was talkin bout how to avoid the problem so ya dont gotta keep fixin it.
