That's a Floyd Rose bridge. The brand of guitar is unimportant. Here's a replay of a livestream I did on this a few weeks ago, by popular demand. It's pretty comprehensive and I changed all the strings. Watch the video, and then if you have any questions, I'm here. I've been restringing and maintaining Floyds Rose guitars for over 30 years.
