Hi John,

Can you tell us what sort of levers you have, please. If you read the descriptions Val posted previously it might help to identify them.

"The common lever styles/brands in America are "blades" (flat piece mounted to one side of the string that rotates to press the string), Robinson (a black plastic lever presses the string toward the neck, pinching it against a pin), Loveland or Jordan (lever is mounted between the neck & the string, & "lifts up" against the string. Loveland are gold plated, Jordan are plastic), or Camac (lever lifts up but moves a fret against the side of the string rather than pressing toward or away from the neck). Blades can be tough to adjust. The others should be able to be moved at least a little without having to re-drill any holes."

You might be able to tighten a screw in the lever, but you might have to take the string off to do that. It depends on the lever type, but normally you don't need to break the strings to fix the levers. The string will have stretched a bit, and it won't make much difference to take it off and put it back on again if the rest of the strings are all still in place and tuned up.

More info would help a lot in trying to narrow down your problem and a possible solution.
