I have a Jackson guitar with a floyd rose.

Recently I have changed the tuning from C# standard to E standard which involved a lot of screwing of the springs which hold the floyd rose mechanism.

So after that and changing strings, a weird squealing noise started to appear when I strum the 5th string and then immediately mute it with my palm. An example of that is in the following SoundCloud link:

This also happens when the guitar is not connected to an amp and the other strings seem to be OK.

Does anyone know what's going on?

On the assumption it only happens on the open A string - and possibly other A notes, it sounds like one of the springs just happens to be at a tension which makes it vibrate sympathetically with that pitch.

Solution: change the tension of the springs very slightly so that none will produce that afternoise.

    Another simple thing to try to remove this possible "wolf tone" is to wrap a rubber band around the springs

    @DoktorMayhem - yes, I did consider a piece of sponge around the springs, if the tension is exactly what's needed, but I'm certain that a particular tension isn't that critical. And, by damping the springs, wolf tones are eliminated on all pitches.

  • @Tim I'll try that as soon as i get home and report the results, thanks! Commented Nov 17, 2023 at 10:18
  • @Tim I've tried to change the spring tension (both tightening and loosening) and still i get this sound. I should note that other A notes are fine - It only happens with the A string. I've tried to hold the spring in question with my hand while strumming the string and the noise did stop. I'll try the dampening method next. Thanks. Commented Nov 17, 2023 at 12:43
  • Yo are talking about the springs that are connected to the claws inside the body? Which generally will be 2 or 3 for the whole block.
