Brand spankin new guitar(month old) with string thru Bigsby. Took a look today and noticed one of the string ball-ends is almost pulled thru the hole totally into the shaft and one ain't far behind. The holes are machined out way larger than needed to feed the string thru. So I'm gonna have to see if I can pull it out today. When I re-string I'm going to line all the ball-ends up and slide a needle thru them so they can't work there way thru the opening again. Maybe a fluke, YMMV.
