Gotoh's ABR-1 bridge is a great replacement for those wire retainer ABR-1 Gibson bridges. This is a rattle free design without the annoying wire and there is more travel room for better intonation. This bridge is standard vintage post mount with thumb wheels. Directly replaces any Gibson or Epiphone with a post mount ABR-1 style bridge.
