Made by Gotoh, these high quality bridges are sturdier than the ABR-1s which is why Gibson went over to this design in the 80s. Instead of the post being screwed directly into the top of the guitar the bridge uses metal bushings which are installed in the top of the guitar and the posts rest in the bushings. The bridges are slightly wider than an ABR-1 allowing for greater intonation adjustment.
2 1/16" string spacing, 2 29/32 post spacing.
