The Gibraltar Standard II is a hard-tail bridge used on Ibanez guitar models. It is a modified version of the Gibraltar Standard that featured more low-profiled edges, making it closer to a traditional hard-tail bridge.
It was introduced for the 2013 lineup, and was used on all the guitars that featured the Gibraltar Standard in previous years, as well as newer fixed-bridge models. In 2014, Ibanez expanded the use of the bridge onto Prestige-series guitars, including the newly-introduced RG652FX, RG752FX, and RG852FX.
As well as being available on 6-string guitars, it's also available for 7-string (Gibraltar Standard II-7), 8-string (Gibraltar Standard II-8), and 9-string (Gibraltar Standard II-9) guitars.
