I have to adjust the saddles on my Ibanez SR300M every few days because they somehow loosen up randomly... I played a show the other night after adjusting them the day before and to my 'surprise' they were clacking and buzzing against the frets.
Loosen a string, remove the offending screw, paint a small amount of the blue stuff onto said screw. Allow it to dry, then reinstall & tune the string back up. Repeat for all bad screws. Once again, use the BLUE stuff- it's removeable. The red is not.
I will try the nail polish trick first, im completely broke and will look into that if the polish doesnt work. luckily i wear nail polish often and dont have to steal any from a friend.
okay, i tried the nail polish, and it seems to have worked just fine.
I went back and did routine setup on the neck and then the saddles, and everything seems to be fine.
