Same as MJMP and SC
I have never had an issue with Floyd Rose or Licensed Floyd Rose trems going out of tune when I dive b*mb or any other use for that matter. Unless the locks are off at the nut of course.
The only trems to ever do this in my experience are trems that
A) either have the lock behind the nut (like my westone dimension see pics) so behave like a vintage trem almost
B) A vintage or non locking trem
A floyd rose style bridge with a locking nut does not go out of tune if you dive b*mb it or pull up unless it's faulty, this is the whole point of locking at the bridge and the nut.
I have 9 (actually 10 cause I'm selling one) guitars with floyd rose (most of them licensed versions as well) and they return to pitch when I dive b*mb till the strings stick to the pickups and string bend to my hearts content.
The only guitar that has locks that behaves different is the westone because it has it's locks are behind the nut as opposed to being on the nut like FR loaded guitars.
I have seen fenders with locks behind the nut also. This is a pretty silly idea because it will still behave like a vintage trem really and when I say that I mean:
it will go out of tune if you use the trem - unless you tune it after trem use then it will stay in tune with trem use but then go out of tune if you string bend to which you will need to use the trem to get it back in tune again.
I spent many years trying to get vintage trems on a strat to stay in tune using both methods (string bends and trem use) and I never beat it. Then I moved to FR locking trems, ISSUE RESOLVED
The only time I need to tinker with tuning on locking systems is due to heat changes. Ireland is cold and going from cold to hot f*cks with the tuning sometimes. Actually sometimes this can happen just by playing a guitar and it heats up, the strings go flat (I'm talking minimal) because the metal expands slightly with the heat. Still they are in tune together at least when this happens.
Well all my jacksons have floyd trems and i have only problems 2 or 3 days after i change my strings and then no problems at all.I can yank these ,make divebombs ,abuse them ,they always return to their pitch.
If I stretch my strings well this does not happen other wise I know what you mean.
