1 Limuz 2 weeks ago I recently noticed that three bushings of the tuners on my 5120 appear to be 'popping out'. It's especially noticeable on the D-string. I'm not sure how long the guitar has had the problem, I don't really pay attention to the headstock that much. It might be a new issue, it might have been there for a few years.Has anyone had this problem and know how to fix it? I really care about this guitar and don't want any lasting damage so I thought I'd ask here. Couldn't find anything online. Thanks!
