basically with a floyd rose or any floating bridge the guitar must be restrung or setup so that the bridge is straight ie parallel with the top of the guitar. to fix your bridge its simple and self explanatory. if its pulled forward tighten the bar spring tension or add more bar springs. if its leaning back do the opposite. also jumping between different string gauges will need you to adjust such settings and also the neck. hope i could help.god gave rock'n roll to you. ta.
