hmmm, never had much of a tuning up prob wid mi floyd equipped guitars last time, i juz over tune up my strings e.g. E to F#, A to B etc... for the first 2 times i tune through, den i stretch and then tune up abt 2-3 times through, abuse the whammy(with the locking pads unlocked), bend all over the place, and tune back up, and juz abuse my strings for the next couple of days, then it stays in tune
want a floyd guitar? this is the price to play, but it will stay in tune when it finally settles in...btw, i grew fed-up of floating trems and prefer fixed bridges now =P
