Problems with my floyd rose

So I was messing around with my guitar last night and it devolped a problem, when ever I depress the whammy bar (push it down) the g string drops down a half step. But after this If i pull the whammy bar up it goes pretty much back to normal. The only thing that I have done recently is change the height of the bridge, because I found that I always had it way to low and the b string buzzed alot. Both locking mechanism are tight and the allen screw holding the locking part down is tight, I have also noticed a very quiet noise when ever I move it up or down. I have no Idea what to do, please help :(

Sorry mate, I don't really understand what the problem is ?? Can you give us some more info and well try to help !

Initially, as I was reading I was thinking that your locking mechanisms weren't engaged on the G string... then you said that they were tight. So, that leads me to believe that when you, or whoever, was stringing your guitar they didn't pull the string completely through. Sometimes strings can get caught on the wraps instead of the bob at the end... most of the time when you're tuning the guitar up the string will achieve a certain amount of tension and it will come loose and you will simply have to keep winding the tuners until it is tight... However, in rare cases the string can catch in a spot that can withstand the tension and won't budge once string tension is applied. This causes severe tuning instability. That is my current diagnosis for you tuning problems. I suggest taking the string out and re-stringing it with a new one.... As for the noise, Floyd Rose trems are mechanical devices, they have moving parts... when parts move in conjusction with other parts, you get some noise. The noise won't transmit through your pickups though... so don't worry. The only time you have to worry about trem noise is if it's a harsh grinding or scraping noise. Slight noise is common in trems that haven't worn in yet. Good luck...

Thanks for the suggestion, just picked up new strings and going to try restringing it. Come to think of the last time I restrung it I had problems with the string popping out of the lock at the bridge. let you know if It works.

No luck, And i have now idea what to do other then bring it to a shop, and the sad part is Im probably gonna have to bring it to the evil empire (Guitar Center) and have it cost an arm and a leg. I'll try to get more speific, don't know how much I can though. When i said the G string drops down to a F#, I meant that after I bring the bar back up from a dive it stays at about an f# when It should be a G. What I think it might be is a problem with the whole part that holds the string. I noticed that the pivot part wobbles from side to side alittle. So I think the pin in the pivot somehow grinded down or moved to one side. Any idea how to fix this? *UPDATE* First is seemed like it was only one string, now the whole things doing it, im taking it into a shop, thanks for trying guys

How many springs are installed on the trem? Some people use 2, but I've found that doesn't give enough overall tension. It's enough to hold the trem level, but not enough tension to keep it going back to a neutral position after doing a bomb dive.....If you have 2 springs, try adding a 3rd, and if you already have 3, try adding a 4th. It'll take some time to adjust the springs to get the correct tension. Don't know if this will help, but it's worth a try.....

Oh, and be sure all the hex nuts are tight at each individual saddle....
