A quality replacement for the vintage Gibson bridge. The one on my reissue is fine, but it's not fixed so it's easy to nudge the action wheels when replacing strings. Also, the strings are biting into the nylon saddles. Apparently the nylon used nowadays is softer than that used in the past.
I don't want to have to worry about my action every time I change strings and the addition of harder nylon made this upgrade a no-brainer. Quality stuff!
