Well those came with one of two completely different trems, so you'll need to provide more details.

Since he said floyd, I'm guessing it has the JT-6. Either the plates in the locking nut are worn or (more likely) the strings are getting hung on the nut in front of the locking mechanism.

Be very specific about what's going on and we may be able to pinpoint whether the problem is at the bridge end (ie. knife edge or saddle issue) or at the nut end (slipping string lock). A couple examples:

Do a full divebomb. If the guitar is sharp afterward, that's usually slippage at the string lock. If it stays flat, it often means the knife edges are bad and aren't letting the trem return to the zero point.

Do a full pullup. If the guitar is flat afterward, think slippage at the string lock. If it stays sharp, think knife edges.

There are other things that can be going on, like spring issues, but on these old JT-6 trems, it's usually damaged knife edges or grooved string lock plates. The plates are easily replaced. Knife edges are not as easy to fix, but some people have been able to fix them with files or a Dremel tool, used very carefully.

Yes, the weak points are the Floyd knife edges and the behind the lock nut. Both are tough to fix. The locknut, specifically the Tawainese made one (not the Kahler made one), are made of a soft metal, so the strings easily groove into the housing. So even replacing the lockplates don't help too much.

BTW, worse thread title EVER!
