Loose tuner bushings :: 2012 Martin OM-42
Here's a loose high e tuner bushing on this Martin OM. There's a fine line when fitting bushings between just right and too loose. Too tight and you can risk damaging the headstock. Too loose can mess with tuning stability. The easy fix is to pull the tuner and bushing and apply superglue to the tuner hole. Once cured, you can test the fit and reapply if necessary. (Do NOT glue the bushings in!)
