Straight from Gibson Guitar's Historic Re-issue guitars come Gibson Gear's new Historic Spec series " parts that have been specially designed to replicate the original parts used by Gibson in the late 1950s. With this Historic Non-Wire ABR-1 Bridge, Gibson has re-created the famous non-wire bridge it used on its electric guitars until 1962-63. "GIBSON ABR-1" is featured in raised letters on the base of the bridge. The vintage bridge also includes un-notched saddles, in order to fully emulate the classic parts. This is the gold version of Non-Wire ABR-1 Bridge, which comes with the full assembly.
